Clinical manifestations of renal cysts: the vast majority of renal cysts without symptoms. Some patients may be increased because of the pressure, the cyst itself and intracystic infection and the following symptoms:
Lumbar, abdominal discomfort or pain: the reason is due to the enlargement and expansion of the kidney, so that the tension of the capsule of the kidney, the renal pedicle was pulled, or adjacent organs caused by pressure. In addition, the kidneys due to polycystic moisture, becomes heavy, pull down, will also cause the waist pain. The pain characterized by pain, dull pain, fixed on one side or both sides of the back to the waist, and the lower part of radiation. If there is bleeding or secondary infection, then the pain suddenly increased. As with stones or bleeding after clot urinary tract obstruction, renal colic can be.
Hematuria: can be manifested as microscopic hematuria or gross hematuria. Onset of periodicity. The onset of back pain is often aggravated, strenuous exercise, trauma, infection can be induced or aggravated. The reason is because there are many blood vessels under the capsule wall, due to increased pressure or infection, so that the blood vessel wall due to excessive traction and rupture bleeding.
Abdominal mass: sometimes the main reason for patients to see a doctor, 60 - 80% can touch the enlarged kidney. The larger the kidney, the worse the renal function.
The amount of proteinuria: not much, 24 hours urine will not exceed 2 grams, so it won't happen in nephrotic syndrome.
The hypertension: solid kidney cyst compression, caused by renal ischemia, the renin secretion, caused by hypertension. In normal renal function, more than 50% of patients with high blood pressure, renal function, the incidence of hypertension is higher.
The decline in renal function due to cyst compression, occupying the normal renal tissue significantly reduced kidney function loss.
