What causes a dilated renal pan?

Hydronephrosis, the condition that occurs when the urine neirine does not emerge from the kidney is the primary cause of the expansion renal pelvis. The renal pelvis is an area in the kidneys where urine collects before the ureter performance, and when the urine is backed up, it expands. Infants and adults are the main populations affected by this problem, which is usually the result of blocking or another problem that limits one or both urinary urees. In infants, the cause is usually a congenital defect in urinary urinary urethra, such as narrowing of pipes or the problem with the valves that control urine drainage. In adults, the dilated kidney pan may result from a number of problems, including tumor pressure or material pressure, structural problems in the kidneys or ureters or disorders due to the disease. They may have one or both urerers, which at the end closest to the kidneys narrower than normal, causing blocking the ureteropelvic intersection or UPJ. Another common problem is that the valves that control the urine flow through the faultUreter, cause urine reflux back to the kidneys.

Adults can develop a dilated renal pan, although it is less common than in infants and can happen for many different reasons. While structural abnormalities can also lead to a condition, it is preferable to occur due to other problems in adults. One of the common problems is the pressure on the uric uric urine network, which causes them to narrow and defend the UPJ. This may be the result of close materials, such as tumors or enlarged prostate or swelling in the surrounding tissues due to inflammation. Pregnant women often exert a dilating pelvis of the kidneys, because the pressure from the growing fetus can easily exert pressure on Nearby ureters and the kidneys.

disease and other health conditions can also lead to an expansion renal pelvis in adults. Urerers can be blocked by blood clots, kidney stones or uric acid crystals, which prevents nor all of the urine outflow from the kidneys. Diseases that cause urinary tract inflammation may be to blame. People who have undergone surgery on their urinary tract sometimes also have problems with drainage of urine from the kidneys.
