Renal pains may cause various diseases of varying severity. Disorders of renal function are often discovered in routine blood or urine investigations. Sometimes, however, back pain or pain in the kidneys lead to a doctor’s visit. Then the doctor has to clarify whether the pain emanates from the back or the paired kidney.
Renal Pain: Where? Right, left or both sides
Renal pains occur in the flanks, especially in the renal pelvis. Depending on whether one or both kidneys are affected, kidney pain can occur right, left, or bilateral. While back pain can affect the movement and often lead to a flexed posture, this is not necessarily the case with kidney pain. If a slight blow with the hand edge, about two to three fingers wide over the pelvic crest, causes pain or strengthens, this indicates a kidney problem. A urine examination can ensure the diagnosis.
Renal pain can also occur during pregnancy, in which it is not clear at first whether there are back pain or kidney pain. Renal pains occur during pregnancy when the pressure on the urine urine back into the renal pelvis system. We then speak of a kidney jam, which should be dealt with quickly. If you have kidney pain, you should visit a doctor. They can indicate serious diseases.
Kidney stones as a cause of renal pain
If you have kidney pain, you should visit a doctor. They can indicate serious diseases. These diseases include, for example:
- Renal cell inflammation as a result of a “highly migrated” cystitis
- kidney infections
- Cystic kidney disease
- kidney cancer
- Kidney stones
- renal gravel
- renal colic
Kidney stones are formed when the urine is supersaturated with substances which form the stone, such as calcium, oxalate, phosphate, uric acid, and cystine. Therefore, people who are prone to stone formation should refrain from using beverages such as coffee, black tea and alcohol, since they accumulate the urine with stone-forming substances.
Usually, certain substances (e.g., calcium binding citrate) hinder the precipitation of a urine from the supernatural urine fluid. If, however, these inhibitors are only present in small amounts, the formation of small crystals, called grit, is an advantage. If the conditions are favorable, this kidneys produce larger stones over time.
Renal colic as a result of kidney stones
As long as it is urinary-grit or small stones, up to 80 percent can be excreted (over weeks) via the ureter and urinary bladder using large amounts of drinking without causing severe pain.
If, however, a large stone travels out of the kidneys, painful colic often occur. A lot of drinking alone is not sufficient. The stones are crushed either with external shocks. The fragments leave by themselves. Or the stones are removed by means of an endoscope or during an open operation. Partially, they also dissolve medically.
Symptoms of renal cell inflammation
Renal pain can be a symptom of renal cell inflammation (pyelonephritis). Renal cell inflammation is an acute or chronic inflammation of the renal connective tissue, which is usually caused by a bacterial infection. However, certain medications and other infections can lead to acute or chronic renal cell inflammation. In acute renal pelvis inflammation, high fever and a sudden, strong feeling of illness occur, except renal pains. After an antibiotic use, the acute renal pelvis usually heals.
Sometimes a chronic renal artery disease (chronic interstitial nephritis) develops from acute. Chronic pelvic inflammation can be symptom-free for a long time, but symptoms such as flank pain can also occur. Another possible cause of renal pains is interstitial nephritis. In particular, the space surrounding the urinary tubules is inflamed.
Cystines cause painful renal growth
Also the mostly inherited cystennies can be responsible for kidney pain. Cystitis is a dangerous renal disease in which both kidneys have more than three cysts. In the long term the cystennies leads to progressive renal failure. At first, symptoms do not usually occur. At a later stage, however, the patients affected more frequently with chronic urinary tract infections, have pain in the kidney area and occasionally also sudden urinary bleeding. Consequently, the kidney can less and less perform its functions. The treatment of cystines is mainly about relieving the symptoms.
Flank pain can also be an indication of a kidney cancer disease. Risk factors for the development of kidney cancer include obesity, smoking, high-fat diet, frequent contact with kidney-damaging solvents, asbestos and chronic kidney disease. Early symptoms are a rarity in kidney cancer. In the advanced stage of kidney cancer, there are also fever, fatigue, loss of appetite, blood in the urine, and possibly bone pain.
