Whether renal cysts have any effect on the body is related to the size and nature of the cysts and other factors, most patients have no obvious symptoms, but can also be manifested as hypochondriacal abdominal pain, erythrocytosis, compression of the intestinal tract or biliary obstruction and so on.
1. Most patients do not have obvious symptoms, and most of them are found incidentally during ultrasound and other imaging examinations. In some patients, abdominal masses can be detected (more common in pediatric patients, mostly larger cysts in the lower pole of the kidney).
2. If the patient has symptoms, the most common is coeliac pain, which can be caused by the larger cyst pulling the renal peritoneum or compressing the renal parenchyma, and can also be caused by the cyst bleeding, infection, etc. Some patients have hematuria and microscopic urine. Some patients have hematuria and microproteinuria.
3. A few patients may have erythrocytosis. Very few patients have compressive intestinal or biliary obstruction. If the cyst compresses the adjacent blood vessels, hypertension may occur as a result of reduced local renal blood flow and elevated renin levels. Once infection occurs, there may be low back pain, pyuria, fever and other manifestations. Rupture of cyst cavity is rare, and once it happens, the consequences are more serious.
If you have renal cysts, please consult your doctor promptly and choose the appropriate treatment plan after evaluation.
