1, adult type renal cysts

Adult type renal cyst is a congenital hereditary disease, kidney parenchyma filled with countless size ranging from the outside world is not connected to the circular kidney cyst. Manifested as nocturia increased, low back pain, high blood pressure and so on.

1, high blood pressure: the disease is the early common performance, and a direct impact on prognosis. According to reports, no azotemia patients nearly 60% of hypertensive patients; normal renal function in patients with hypertension when the kidney was significantly greater than normal blood pressure.

2, renal dysfunction: 30 years of age rarely occurs before chronic renal failure, to 59 years old when about half of the patients have lost renal function and the need for alternative treatment.

3, kidney enlargement: can be greater than normal 5-6 times, both sides may have significant differences. Early renal enlargement imaging examination can be found in severe abdominal palpation can be found.
