Correct kidney pain correctly

Behind kidney pain can be different diseases of different severity stuck. Kidney function disorders are often discovered in routine blood and urine tests. Sometimes back pain or pain in the kidney area lead to a doctor's visit. Then the doctor must clarify whether the pain emanating from the back or the paired kidney.

Kidney pain: where? Right, left, both sides

Kidney pain occurs in the flanks, especially in the renal pelvis. Depending on whether one or both kidneys are affected, kidney pain may be right, left or bilateral. While back pain interferes with exercise and often results in a stooped posture, kidney pain is not necessarily the case. If a slight slap with the edge of the hand, about two to three fingers wide over the iliac crest, causes or amplifies pain, this indicates a kidney problem. A urine test can secure the diagnosis.

Renal pain may also occur during pregnancy, although it is initially unclear whether it is back pain or kidney pain. Kidney pain occurs during pregnancy when the urine returns to the renal pelvic system due to pressure on the urinary tract. One then speaks of a kidney congestion, which should be treated quickly.

Kidney stones as a cause of kidney pain

If you have kidney pain, you should definitely consult a doctor. They can indicate serious illnesses. These diseases include, for example:

  • Renal pelvic inflammation as a result of "migratory" cystitis
  • kidney infections
  • Cystic kidney disease
  • kidney cancer
  • Kidney stones
  • renal gravel
  • renal colic

Kidney stones are formed when the urine is supersaturated with stone-forming substances such as calcium, oxalate, phosphate, uric acid and cystine. Therefore, people who tend to stone should refrain from drinks such as coffee, black tea and alcohol, as these enrich the urine with stone-forming substances.

Normally, certain substances (for example, calcium binding citrate) make it difficult for a urinary substance to precipitate out of the supersaturated urine. However, if these inhibitors are present only in small amounts, this favors the formation of initially tiny crystals, called semolina, in addition. If the conditions are favorable, over time larger kidney stones develop from this semolina.

Renal colic as a result of kidney stones

As long as it is a meal made of urine or small stones, 80 percent of it can be excreted via the ureter and urinary bladder via the ureter and bladder, without causing severe pain. As additional home remedies here offer moist lumbar wrap and hot full baths.

If, on the other hand, a large stone migrates out of the kidney, painful colic often develops. Then a lot of drinking alone is not enough. The stones are either crushed with shock waves from the outside. The fragments go away by themselves. Or the stones are removed by endoscope or in an open surgery. Partly they also dissolve medically.

Symptom of pyelitis

Kidney pain can be a symptom of pyelonephritis. Renal pelvic inflammation is an acute or chronic inflammation of the renal connective tissue, most of which is caused by a bacterial infection. However, certain medications and other infections can lead to acute or chronic pyelitis.

In acute pyelonephritis, except for kidney pain, high fever and a sudden strong feeling of illness occur. After taking an antibiotic, the acute pyelonephritis usually heals.

Sometimes acute outbreaks develop chronic pyelitis (chronic interstitial nephritis). Chronic pyelitis can be symptom-free for a long time, but it can also cause symptoms such as flank pain. Another possible cause of kidney pain is interstitial nephritis. In particular, the space surrounding the urinary canals is inflamed.

Cystic kidneys cause painful kidney remodeling

Even the mostly inherited cystic kidneys can be the cause of kidney pain. Cystic kidney is a dangerous kidney disorder in which both kidneys have more than three cysts. In the long term, the cystic kidney leads to progressive renal failure.

In the beginning there are usually no symptoms. At a later stage, however, sufferers then frequently suffer from chronic urinary tract infections, have pain in the kidney area and sometimes even sudden bleeding. As a result, the kidney is less able to perform its tasks. In the treatment of cystic kidneys, it's all about alleviating the symptoms.

Kidney cancer as a cause of kidney pain

Flank pain can also be an indication of kidney cancer. Risk factors for the development of kidney cancer include:

  • overweight
  • Smoke
  • high-fat diet
  • frequent contact with kidney-damaging solvents and asbestos
  • chronic kidney disease

Early symptoms are a rarity in kidney cancer. In addition to flank pain, fever, fatigue, loss of appetite, blood in the urine and possibly bone pain occur in the advanced stage of kidney cancer.
