kidney pain


Renal pain is a pain sensation that is projected onto the kidney area. These are localized in the flank region, which extends laterally from the abdominal wall from the costal arch to the groin. For this reason, renal pain is also referred to as flank pain.

Kidney pain: left, right, bilateral?

Kidney pain can be either left, right, or bilateral, depending on which kidney is affected.

However, since both kidneys, as a paired organ, perform the same tasks, the causes and nature of left and right side kidney pain hardly, if at all, differ.
More important are more information, especially about accompanying symptoms and the pain character. This will be discussed in more detail in the following sections.

Kidney pain left

Unilateral kidney pain, whether left or right-sided, can occur in pyelonephritis .

It is usually caused by a colonization with bacteria, often it develops from a complicated urinary tract infection. In addition to the pain, accompanying symptoms of kidney pelvic inflammation are often fever and chills. Also in the context of a bladder infection may occasionally cause pain in the kidneys in this case, however, usually both kidneys are affected.

Another cause of unilateral, for example, left-sided kidney pain is renal colic . This is caused by kidney stones. The stones may either lie in the area of ​​the kidney or have already reached the draining urinary tract. This means that the pain can migrate.

So it can only be in the kidney area, but later it can come to a charisma in groin and flanks. However, kidney pain is not always due to kidney disease and may be due to other causes.

Left-sided kidney pain, which mainly occurs during exercise, rarely has an actual kidney disease as its cause. Here are more likely muscle strains or diseases of the spine as causes in question. Even if kidney pain occurs when coughing, for example, in the context of a cold, this is more likely to suggest a tension in the muscles.

If unilateral kidney pain occurs during pregnancy, this may be an indication of a urinary retention. This means that the urine on the one hand can no longer drain sufficiently from the kidney via the ureter. This can be achieved, for example, by the fact that the significantly enlarged uterus presses on the ureter. However, kidney pain during pregnancy is often a symptom that only lasts for a short time and does not pose a risk.

For prolonged kidney pain during pregnancy, a doctor should be consulted. Even with non-pregnant women with kidney pain can be considered a rule of thumb: If there is a kidney pounding pain, it is likely that the disease comes from the kidney. To check the kidney pains, lightly hit the area where the left / right kidney is lying with the edge of the hand. If the cause of the kidney pain is a tension or a problem with the spine, the kidney is usually not bumpy.

Nocturnal kidney pain during pregnancy

Especially in women in advanced pregnancy it comes through the size of the growing child to completely different space in the abdomen.

Thus, the uterus displaces the surrounding organs to a not inconsiderable extent with the child embedded in it. Often, the ureters are also restricted by the child. Both kidneys are no longer able to pass the urine produced by the mother unhindered into the bladder, which may result in a backflow of urine into the kidneys.
This results in deep ultrasound of kidney pelvis and kidneys appearing on ultrasound.

The backflow often causes severe pain in the kidneys (often on both sides). When sleeping at night, it can happen that if the woman is lying on her back, the pressure of the child is so great that the ureters are severely restricted and it comes to a sudden renal congestion. Lateral storage leads to early recovery.

Kidney pain after alcohol

Occasionally, sufferers are reported to experience kidney pain after consuming alcohol or already having it. This can not be scientifically explained. It is also true that pain that occurs simultaneously in the region of both kidneys, usually have no kidney disease as a cause.

The exception to this is cystitis. However, kidney stones or inflammation of the renal pelvis are usually associated with unilateral pain. If you experience repeated kidney pain when drinking alcohol, which otherwise would not show, then the attempt of alcohol abstinence would be a way to relieve the symptoms.

If the pain occurs again and again regardless of alcohol consumption, for example, kidney stones can be responsible for this. The pain usually occurs here in waves and are very strong, it is called a renal colic.

After having had renal colic a doctor should be consulted as the kidney stones may need to be treated.

Kidney pain after alcohol withdrawal

Alcohol withdrawal is not known to cause kidney pain.

Kidney pain with nausea

The combination of kidney pain and nausea occurs especially in the presence of kidney stones. If a kidney stone displaces the renal pelvis or the ureter and progresses slowly, recurring colicky pains will result. These are very strong and are therefore often associated with nausea and vomiting. #

Painkillers and anticonvulsants help with renal colic. If the nausea occurs in the renal colic, it is usually over after completing the colic. Of course, kidney pain and nausea can also occur independently.

Kidney pain in pregnancy

Kidney pain during pregnancy can be a harmless symptom that only lasts for a short time. However, you can also return. For example, a possible symptom of kidney pain during pregnancy may be a urinary drainage disorder. This can be due to the fact that the uterus, which is significantly enlarged by the pregnancy, presses on one or both ureters.

This can lead to a more or less pronounced urinary retention. If it is just a slight variation, the expectant mother can be symptom free. However, due to the urinary instinct, the risk of developing a urinary tract infection is increased. In severe congestion, it can cause pain in the flank, usually one-sided, but sometimes also on both sides.

For recurring kidney pain during pregnancy, a doctor should be consulted, who can determine by means of an ultrasound examination, whether a urine retention is present and whether a treatment is necessary. Generally applies to expectant mothers with kidney pain: a lot of drinking and heat applications help.

Kidney pain after cystitis

Bladder infection is often manifested by frequent urination and burning sensation. Occasionally, as part of such a urinary tract infection may also cause kidney pain. This can be harmless, but should also be seen as a warning signal. Because an untreated cystitis can spread to a renal pelvic inflammation.

This happens because the bacteria "ascend" from the discharging urinary tract to the kidney and cause inflammation there. This so-called pyelonephritis is then associated with kidney pain and often fever and chills and must be treated with antibiotics.

Because of this risk, kidney pain that has come on or after a cystitis has been taken seriously. Kidney pancreas is usually a disease of only one of the two kidneys, so the pain is usually localized on one side.

Kidney pain in case of a cold

Kidney pain that occurs as part of a cold is often no real kidney pain. Rather, it is back pain or muscular pain in the sense of a slight soreness, for example, after a long cough.

If it really is kidney pain, they probably have a different cause than the common cold, such as a bladder infection.

Kidney pain at night

Nocturnal kidney pain is not a specific symptom. Often pain in the spine can be misjudged as a kidney pain. If there are repeated nocturnal pain in the area of ​​the kidney, a doctor should be consulted for further diagnostics.

Kidney pain in the morning

Kidney pain in the morning is just as little as nocturnal kidney pain, a symptom that is indicative of a specific condition. Often it is actually not kidney but back pain caused by wrong nightly lying.

Kidney pain due to painkillers

There are painkillers that are harmful to the kidney. These include drugs from the group of non-steroidal anti-inflammatory drugs. Representatives of this group are for example ibuprofen and diclofenac. When taken occasionally, these medicines are harmful to kidney health.

However, if they are taken permanently in high doses or if they are regularly used by someone whose kidneys are already affected, this can lead to a progression of kidney damage. Pain usually does not develop as a result of such kidney damage.

Can kidney pain be a sign of pregnancy?

Some women describe kidney pain that they would have felt in early pregnancy. Why this symptom occurs is unclear.

Causes of kidney pain

Regardless of whether the pain is in the left or right kidney, it can be an indication of various diseases.

Kidney pain is a relatively specific symptom; This means that pain in the kidney area can often indicate a process in the kidney or in the urinary tract.

Back pain and kidney pain

Back pain can also cause pain in the kidney, which could then be misinterpreted as "real" kidney pain.
The cause of this could be, for example, slight bony deformities of the spine, degenerative changes or muscle tension.

Therefore, it is important to consider back pain when looking for a cause of existing kidney pain.
There are some clues that can help with this question:

  • For example, back pain is when the pain increases with exercise,
  • For kidney pain, however, speaks a so-called "kidney bearing knocking pain":
    This means that tapping the kidney stock (left and right of the spine about two to three fingers across the palpable iliac crest) increases or elicits pain.

If the suspicion of kidney disease can not be eliminated, kidney-related causes must be considered.

Kidney stones

The most common cause of kidney pain is kidney stones.
These occur in about 4% of the population in Germany, especially between the 35th and 65th year of life. They are more common in men than in women.

Kidney stones are small accumulations of substances from the urine, which become noticeable either in the area of ​​the kidney or only in the area of ​​the ureters, because they are too large to be excreted freely with the urine. The most common type of kidney stones are the calcium oxalate stones .

Kidney or ureteral stones typically cause colicky pain. The pains flood in waves, get stronger and then flood again, they are usually followed by a pain break.
Depending on the location of the stone, the pain radiates more into the area of ​​the kidney or into the flanks, into the groins or, in the case of very deep-seated stones, into the genital region. Pain in crotch may also be accompanied by painful urination.
Also, nausea and vomiting are common accompanying symptoms of ureteral stones.

During the colic painkilling agents are administered, which reduce the wall tension of the ureter as much as possible and thus also provide for a reduction in pain. Here Novalgin® is ideal.

Depending on the size and location of the kidney stones can be treated conservatively, so here is waiting until the stone goes off by itself, that is excreted. This is possible for stones up to about 5 mm in size. The patient should move and drink a lot to stimulate the finish.
If this is not successful, or if the stone is larger, various methods can be used, which include crushing the stone and the subsequent distance to the target.


Another major cause of (one or two-sided) kidney pain is pyelonephritis, which usually results from cystitis .
Bladder and kidney pelvic inflammation is particularly common in women, as the female urethra is much shorter than the male.

Cause of the inflammation is usually a colonization of the urinary tract with bacteria. The pain here is not like the kidney stones colicky but rather permanent and increasingly.

Common accompanying symptoms are:

  • high fever,
  • chills
  • and severe feeling of illness.

In recent years, moreover, a bladder infection with typical symptoms such as:

  • Pain when urinating,
  • frequent urination
  • and possibly dark-colored, strong-smelling urine,

It is very likely that a pyelonephritis is the cause of kidney pain.

kidney cancer

Kidney cancer can also be painful but more advanced. In the early stages, there is more blood in the urine and physical exhaustion as a sign. In addition, weight loss often occurs.
Thus, if only kidney pain without the other symptoms described before, a kidney cancer disease is unlikely.

In summary, it can be said that kidney pain can be an indication of various clinical pictures. It is therefore important to look at other symptoms such as fever or blood in the urine and the diagnostic examination.

If the kidney pain is accompanied by other symptoms or persists for several days, a visit to a doctor is recommended.
The general practitioner can assess the clinical picture and initiate a therapy or, if necessary, refer directly to a urologist.

Diagnosis and clarification of kidney pain

The most important imaging for kidney pain is sonography

As is the case with all diagnostic findings, the history of kidney pain also begins with:
It is especially important to find out

  • how long the complaints already exist,
  • with what other symptoms they go along
  • and what character the pain has.

Subsequently, in the physical examination a painfulness of the kidney stock can be tested.

This is complemented by a blood and urine examination and imaging techniques.
In the blood, the inflammatory parameters (white blood cells, CRP) are determined in kidney pain, to see if there is an inflammation in the body.
In addition, the kidney-specific values ​​(urea, uric acid and creatinine) are of concern, as the doctor can see if kidney performance has been impaired.

The urine is examined for blood, bacteria, white blood cells ( leukocytes ) and the pH value (acidity of the urine). In addition (if a urinary tract infection is suspected) a urine culture can be created. If bacteria were the cause of the complaints, they would be determinable.

The most important imaging technique used to treat kidney pain is the ultrasound of the kidneys, including the urinary tract. An experienced examiner can thus recognize completely radiation-free the most important clinical pictures.
In the case that the ultrasound examination can not make an accurate statement, X-ray images of the abdomen, computed tomography (CT) or magnetic resonance imaging (MRI) are optionally made.

In case of special questions excretory urography (to determine the residual urine volume and visualization of the urinary tract) or a reflection of the ureter ( ureterorenoscopy ) and the bladder ( cystoscopy ) can be performed.

    Here are a few examples of the most common diseases that can cause kidney pain and the respective diagnostic route:

    • Kidney pelvic inflammatory disease is diagnosed on the basis of inflammatory values ​​in the blood, urine examination (bacterial and leukocyte detection) and ultrasound, sometimes in combination with computed tomography.
    • Stones can be found by means of ultrasound, x-ray of the abdomen or excretory urography.
    • Kidney trauma is best diagnosed with ultrasound, X-ray, CT and excretory urography.
    • The diagnosis of kidney cancer is made mainly by ultrasound, X-rays / CT and laboratory changes.
    • In the ultrasound, stenoses can be closed by urinary tracts that have been dilated in the context of a urinary stasis. In kidney pain, kidney scintigraphy is also performed, whereby the excretory capacity of the kidneys is measured in a side-by-side comparison. Side differences may be associated with narrowing in combination with other diagnostic procedures.
    • Ultrasound, a bladder reflex and a micturition cystourethrourography are useful for the diagnosis of urinary reflux. Contrast agents are injected into the bladder and, above all, the urinary tract as well as the micturition are assessed.
    • For the detection of renal infarction mainly computer tomography and angiography ( vascular imaging ) are used.

      Accompanying symptoms

      The position of the kidneys is often not properly understood by those affected, so it happens that kidney pain is described, but the pain continues to develop deeper, namely in the area of ​​the spine.
      The kidneys spread approximately laterally in the adult 25-30 cm above the pelvis.

      When it comes to kidney disease, it usually affects only one kidney at first, so symmetrically reported pain would be unusual but not impossible.

      On the other hand, unilateral pain along the spine may well indicate a disease of the kidney and the urinary system.

      Especially if the pain pulls forward unilaterally around the flank and at the level of the bladder, the urinary system should be shortlisted as a cause.

      If the kidneys or the urinary system are affected, the pain can also radiate, first pointing to another organ, which is diseased. Kidney problems can therefore be associated with pain from other localizations.

      Kidney pain and abdominal pain

      The kidneys are bilaterally connected to the urinary bladder via the ureter ( ureter ).
      This ensures that the kidney-filtered urine safely reaches the storage reservoir - the urinary bladder. The ureters pull from the renal pelvis of the kidney on both sides of the fuselage at an angle to the front.

      At the back wall of the bubble The ureters from left and right then enter the urinary bladder.

      On their way from the renal pelvis of both kidneys, the ureters cross the lateral edge of the abdomen.
      Common diseases, especially in women, are urinary tract infections that may originate in the urethra and then ascend. On the way up the infection enters the bladder - it comes to a bladder infection.

      If not treated, the ureters are usually affected unilaterally or bilaterally. When incipient urinary tract infection patients usually complain only about burning on urination and a so-called Pollakisurie - a frequent urinary urgency without sufficient amount of urine.

      If the infection reaches the urinary bladder, pressure pain at the level of the urinary bladder, in addition to painful urination, also occurs. These complaints can easily be dismissed as a stomach ache.

      When examining the abdomen just above the bladder is often painful. This is due to the projection of the pain from the bladder upwards. If the urinary tract infection continues to rise and reaches the ureters, it will take a not inconsiderable path through parts of the abdomen. At all stages in the course of the ureter, an ascending infection of the urinary tract can cause oppressive or drawing pains, which are described as abdominal pain and sometimes are due to the corresponding projection of the nerves.

      Also relatively often it comes to ureteral stones. Mostly they take their origin in one of the kidneys. Here it comes to classic, usually one-sided pain of the kidneys.

      Kidney stones can detach and then pass through the renal pelvis into the ureter. Via the ureter they walk down towards the urinary bladder and can cause pain in the entire way down. This pain results from irritation of the ureters when the kidney stone gets stuck to the wall.

      The pain is thus often described as a stabbing back or flank pain.
      If the stone gets into the bladder, it usually does not cause so much discomfort.
      However, a feeling of pressure in the abdomen is often described. On the way down there can always be strong colic in the flank and abdomen. This colic results from a sticking of the stone in the thin ureters.

      Nausea and fever

      Especially with colicky pain, which arise in the area of ​​the ureter and are caused by small kidney stones, it may happen that in addition to the strong abdominal pain and accompanying symptoms are given by the patients.

      In severe colic, the patient is usually in extremely bad shape. Due to the strong pain, which occur in waves, it usually comes reflexively to nausea or even vomiting. Colic pain is often a never experienced pain intensity.

      Fever usually does not occur in a renal colic. If it comes to kidney or abdominal pain associated with fever should always be thought of an infectious cause. As a rule, the urinary tract infection comes in the shortlist.
      In the presence of fever, however, it is either a severe urinary tract infection that has not been treated for a long time, or a high-grade urinary tract infection that has reached the renal pelvis. It is also known as pyelonephritis ( pyelonephritis ). This is a serious complication of urinary tract infection. Not infrequently the patients have high fever, severe nausea and vomiting. The general condition is usually extremely bad, a rapid therapeutic procedure is urgently needed.

      In terms of differential diagnosis, nausea and fever associated with abdominal pain should always be thought of as a cause in the gastrointestinal tract. In particular, gallbladder inflammation, pancreatitis or biliary colic would be considered.

      In biliary colic it is similar to renal colic. A gallstone has grown into the gallbladder and now pushes itself through the narrow bile duct system. Whenever it gets stuck on a wall of the bile duct, it causes extreme pain in the abdominal area. These biliary colic can also be associated with nausea and vomiting.

      High fever, on the other hand, often occurs only with gallbladder inflammation or bile duct inflammation. The final diagnosis and distinction should be clarified by ultrasound examination of the kidneys and the gastrointestinal system. Also, laboratory tests of the blood give clues to the cause of the complaints.


      It is true that the patient is sometimes reported to have nausea, fever and vomiting as well as urinary or renal disease.

      However, this is more common in infections of the gastrointestinal tract. When the bile ducts are traversed by a stone or a strong inflammation of the bile duct or gallbladder, it may happen that the bile acids necessary for the digestion no longer enter the intestine in the amount as usual. This can sometimes lead to incomplete digestion, which the patient feels through pulpy bowel movements or watery diarrhea

      If all symptoms (kidney pain, abdominal pain, nausea, vomiting and fever) appear, a general influenza infection should also be considered. This is not a single organ affected, but rather the weakening of the organism by the virus to the symptoms to blame.

      Therapy / What to do?

      The therapy of kidney pain initially aims to reduce the pain.
      Then the respective underlying cause is treated causally.

      Homeopathy for kidney pain

      Numerous homeopathic remedies are touted for the treatment of kidney pain. These include Goldenrod ( Solidago ), Berryis vulgaris, Sarsaparilla, Siambenzoic acid ( Acidum benzoicum ) and Cactus cacti

      They are said to relieve pain, have an anti-inflammatory effect and be effective against kidney stones.

      pain relief

      Kidney pain in general can be alleviated by many painkillers or completely eliminated. For example, preparations such as paracetamol or Novalgin® are used. For example, in case of severe pain, a dosage of 500 mg paracetamol 3x daily or Novalgin® 500 mg 3x daily can be chosen. It is important to make sure that the cause must be investigated if the pain returns after the painkiller has been discontinued.

      To relieve kidney pain, it is important to drink a lot. As a result, the kidneys are sufficiently "flushed". Also, heat applications are often helpful in kidney pain. Place a not too hot cherry stone pillow or a hot water bottle on the painful area.

      Cause-oriented treatment

      If the cause is a kidney stone that has grown up in one of the kidneys and causes pain there, you should pay attention to a sufficient amount of drinking water and, if necessary, increase it to 2-3 liters. In addition, should be paid to a regular exercise.
      As a rule, the kidney pain disappears as soon as the kidney stone has detached and is excreted in the urine. The fluid intake and exercise are therefore one of the most important treatment measures for kidney stones in kidney stones.
      If the stone does not go out, you can think about a stone fragmentation.

      If the cause of kidney pain is urinary tract infection or pyelonephritis, timely antibiotic treatment should be used to prevent kidney complications. Mostly so-called broadband antibiotics are used, which should be taken regularly for up to 10 days. As soon as the effect has begun, most of the time, the symptoms in the kidney area disappear.

      A urinary retention can also lead to moderate to very severe complaints in the kidney area. It comes about through a drainage obstruction at one or more points of the urinary system. These include transfers through a ureteral stone or through a tumor. It can also lead to a kidney congestion in pregnancy, which is due to the fact that the child in the uterus has become so large that it presses on one of the ureter of the mother and urine can no longer get from the kidney into the bladder, Timely discharge is essential, so that the kidney pain soon subside.

      Home remedy for kidney pain

      In addition to the conventional non-herbal medicines that can be used to treat kidney pain, there are also numerous alternative methods of treating kidney pain in general. Again, exploring the cause is important.

      Urinary tract infections that cause kidney pain can be treated very well with stinging nettle and cranberry preparations. Kidney and bladder tea can quickly lead to a relief of the symptoms. The juniper is also attributed a kidney protective and healing effect. Auch wird immer wieder beschrieben, dass Löwenzahnblätter zu einer wohltuenden Wirkung bei Schmerzen im Nierenbereich führen. Wichtig ist auch hier die Trinkmenge entsprechend anzupassen. Es sollte zwischen 2 und 3 Liter bei einem akuten Harnwegsinfekt getrunken werden. Zur Vorbeugung eines weiteren Harnwegsinfekt sollte gleiche Trinkmenge angestrebt werden.

      Schmerzen im Bereich der Nieren und des Rückens sind oftmals sehr gut mittels Wärmeanwendung zu behandeln. So kann entweder eine Wärmflasche, die mit einem Handtuch umwickelt wurde, auf die schmerzende Stelle gelegt werden oder aber ein zuvor im Backofen erwärmtes Handtuch kann diese Aufgabe übernehmen. Auch der Einsatz von Wärmelampen, wie sie etwa bei der Erkältung und bei der Nasennebenhöhlenentzündung zum Einsatz kommt, kann schnell zu einer Linderung führen, wenn man die Bestrahlung regelmäßig durchführt. Auch wärmende Bäder, die aber nicht zu heiß sein sollten, können zeitnah zu einer Schmerzlinderung im Bereich des Rückens führen.
      Wichtig ist, dass der Rücken entlastet wird und nicht noch zusätzlich schwere Lasten getragen werden. Beim Liegen kann man versuchen den Rücken durch die sogenannten Stufenlagerung zu entlasten. Dabei legt man die Unterschenkel auf mehrere Kissen und erreicht so das Aussehen einer Treppe.

      Neben den wärmenden Maßnahmen können auch zahlreiche Salben und Gele auf den schmerzenden Bereich der Niere aufgetragen werden. So kommen Kytta-Salbe, Pferdebalsam und ähnliches ergänzend oder ausschließlich zum Einsatz. Auch kann die Haut über den schmerzenden Nieren mit warmem Massageöl beträufelt werden. Der wärmende Faktor ist einer der wichtigsten Behandlungsansätze bei der Schmerzbehandlung von Nierenschmerzen. Wichtig ist zu beachten, dass die Wärmezufuhr sofort gestoppt werden sollte, wenn sich der Schmerz im Bereich der Nieren dadurch verschlimmert. In diesem Fall ist eine schulmedizinische Behandlung sowie eine genaue Ursachensuche der Beschwerden einzuleiten.

      Hausmittel in der Schwangerschaft

      Treten Nierenschmerzen rechtsseitig oder linksseitig der Wirbelsäule während der Schwangerschaft auf, sollte noch intensiver nach der Ursache gesucht werden als man dies bei nicht Schwangeren tun würde. In der Vielzahl der Fälle handelt es sich bei den angegeben Beschwerden in der Schwangerschaft nicht um Nierenschmerzen sondern um Rückenschmerzen, die durch die ungewohnten orthopädischen Belastungen auf den Körper zustande kommen. So zieht das Kind den Rücken der stehenden Mutter nach vorne. Die Rückenmuskulatur wird somit äußerst stark belastet, da die Mutter immer dem Gewicht entgegenhalten muss.
      Wird trotzdem deutlich, dass die Schmerzen auslösende Ursache die Nieren der Schwangeren sind, sollte unbedingt nachgeschaut werden, ob es zu einem Nierenstau gekommen ist. Diese Abflussstauung ist relativ häufig bei Schwangeren, da das heranwachsende Kind in der Gebärmutter so groß ist, dass es Teile der Harnleiter verlegen kann und so den Abfluss des Urins gefährdet. Das Resultat ist ein Aufstau in eine oder beide Nieren. Die wichtigste Behandlung ist die Entlastung der Harnleiter, um den Abfluss wieder zu ermöglichen. Als Hausmittel bei Nierenschmerzen bei Schwangeren können wärmende Maßnahmen, wie Wärmekissen oder Wärmflasche angewandt werden, oder es kann der Rückenbereich mit einem Rotlicht bestrahlt werden. Auch können wärmende und kühlende Salben oder Gels auf die Haut über der Nierenregion aufgetragen werden. Oftmals kommen Franzbranntwein, Kytta-Salbe oder Pferdebalsam zum Einsatz. Auch kann vorher angewärmtes Massageöl auf den Hautbereich aufgetragen werden. Zur allgemeinen Schmerzbehandlung können auch Arnikasalbe auf den Nierenbereich aufgetragen werden. Unterstützend hierzu kann auch Arnika in Globuli-Form verabreicht werden. Da es sich hierbei um homöopathische Arzneimittel handelt, sind sie auch in der Schwangerschaft unbedenklich einzusetzen.

      Ebenfalls wichtig ist die Entlastung des Rückens, weil die starke Beanspruchung der Muskulatur um die Wirbelsäule zusätzlich zu Schmerzen führen kann. Die Schwangeren sollten sich aus dem Grund öfters in eine seitliche Liegeposition begeben, um entsprechende Entlastung herbeizuführen. Ebenfalls sehr gut einsetzbar ist das Auflegen von Heublumenkissen. Hierbei kann man Heublumen in einen Stoffbeutel oder leeren Kissenbezug legen und dann erwärmen. Das erwärmte Kissen sollte dann auf die schmerzenden Stellen gelegt werden. Durch die Erwärmung der Heublumen sind Öle entstanden, die sich dann durch den Beutel auf die Haut des Betroffenen übertragen und so zur Linderung der Beschwerden führen können. Eine regelmäßige Anwendung sollte zu Beginn der Behandlung angestrebt werden. Wichtig ist zu beachten, dass alle wärmenden Behandlungsmaßnahmen abgebrochen werden sollten, sobald sich die Beschwerden verschlechtern. Hier sollte dann ärztlicher Rat eingeholt werden, da eine umfassende Diagnostik durchgeführt werden sollte.


      Um die Entstehung von Nierenschmerzen im Rahmen einer Nierenbeckenentzündung zu verhindern, sollte man Kälte und Luftzüge im Bereich der Blase sowie der Nieren vermeiden.

      Nierenschmerzen, die durch Steine verursacht werden, kann man vorbeugen, indem man viel trinkt und wenig Salz sowie Eiweiß zu sich nimmt.

      Nach einem Nierentrauma ohne direkt ersichtliche Verletzungen sollte trotzdem – auch wenn keine Nierenschmerzen vorliegen - alle 6 Monate eine Kontrolle der Nieren für einen Zeitraum von mindestens 5 Jahren vorgenommen werden.

      Nierenkrebs kann gegebenenfalls positiv durch die Vermeidung der genannten Risikofaktoren beeinflusst werden.

      Bei Veränderungen wie Stenosen oder Harnreflux existiert keine Prophylaxe.

      Der Vorbeugung eines Niereninfarkts dienlich sein kann eine Veränderung des Lebensstils, um Gefäßverkalkung (Arteriosklerose) zu verhindern. Hierzu gehören Nikotinverzicht, gesunde Ernährung (mediterrane Kost), wenig Alkohol (


      kidney pain

      Die Prognose für den Verlauf von Nierenschmerzen richtet sich nach der zugrunde liegenden Erkrankung.

      Unkomplizierte Nierenbeckenentzündungen heilen unter antibiotischer Therapie in der Regel ohne Schäden aus.

      Steine als Verursacher von Nierenschmerzen gehen in 75% der Fälle spontan ohne ärztliche Maßnahmen ab. Ein Rezidiv tritt jedoch bei 50 bis 100% der Patienten auf.

      Liegt ein Nierentrauma als Ursache der Nierenschmerzen vor, ist bei 15% der Fälle eine Entfernung der Niere ( Nephrektomie ) von Nöten.

      Die Prognose von Nierenkrebs hängt vom Stadium des Tumors ab. Bestehen noch keine Metastasen ( Tochtergeschwulste ), liegt die 5-Jahres-Überlebensrate bei 65%. Ist der Tumor hingegen bereits metastasiert, verschlechtert sich die Prognose.

      Stenotische Veränderungen können in der Regel durch die Operation geheilt werden; die Prognose ist gut.

      Bei angeborenem Harnrückfluss ist eine Rückbildung bis zum 10. Lebensjahr ohne ärztlichen Eingriff möglich.

      Nach einem Niereninfarkt liegt die 5-Jahresfunktionalität bei 70 bis 85%, ersichtlich an einem normalen Blutdruck, da dieser von den Nieren beeinflusst wird. Darunter versteht man, dass sich bei 70 bis 85% der Patienten mit einem Niereninfarkt nach 5 Jahren der Blutdruck normalisiert, was ein Zeichen für eine adäquate Nierenfunktion darstellt.


      Bei Nierenschmerzen handelt es sich um Flankenschmerzen, in der seitlichen Bauchregion lokalisierte Schmerzempfindungen. Ihre Ursache ist meist in krankhaften Veränderungen der Nieren oder der ableitenden Harnwege zu finden. Dazu gehören Nierenbeckenentzündung ( Pyelonephritis ), Nieren oder Harnleitersteine ( Nephrolithiasis, Ureterolithiasis ), Nierentrauma, Nierenkrebs, Verengungen der Abflusswege ( Stenose ) mit nachfolgendem Harnstau, Harnrückfluss ( Reflux ) oder Niereninfarkt durch Verschlüsse der Nierengefäße. Nierenschmerzen können jedoch auch unabhängig von der Nieren und den Harnwegen, beispielsweise durch muskuläre Veränderungen, Bandscheibenvorfälle der BWS oder Gürtelrose (Herpes Zoster), entstehen.

      Diagnostisch wegweisend für die Ursache von Nierenschmerzen sind neben Anamnese und körperlicher Untersuchung die Bestimmung bestimmter Laborparameter (Nierenwerte, Entzündungswerte), die Untersuchung des Urins, Ultraschall der Nieren und der Blase ( Sonographie ) sowie weitere bildgebende Verfahren (Computertomographie, Ausscheidungsurographie, Blasenspiegelung, Harnleiterspiegelung).

      Therapiert wird je nach Grunderkrankung entweder konservativ oder operativ: Nierenbeckenentzündungen werden in der Regel antibiotisch behandelt, Steine bei fehlendem Spontanabgang zertrümmert und Traumata, Krebs, Stenosen sowie Reflux meist operativ versorgt.
