The vast majority of renal cysts and asymptomatic.Some patients may be increased due to the cyst itself and the intraluminal pressure,infection, and the following symptoms:
① waist, abdominal discomfort or pain
The reason is that the tension increases due to kidney enlargement and expansion of therenal capsule, the renal pedicle by traction, or to adjacent organs caused by compression. In addition, kidney polycystic kidney water content, become heavy, fallingtraction will cause lower back pain. The pain is characterized by pain, dull, fixed in one or both down, waist back radiation. If intracystic bleeding or secondary infection, make the pain flare. Such as the merger of the stones or bleeding blood clots blocking the urinary tract, can renal colic.
② hematuria
Can be expressed as microscopic hematuria or gross hematuria. The onset of cyclical.Attack of low back pain, often exacerbated by strenuous exercise, trauma, infection can be induced or aggravated. The causes of bleeding because of the wall below the numberof arterial pressure to increase co-infection, so that the wall of blood vessel rupture dueto excessive traction.
③ abdominal mass
Sometimes as the main reason for patient visits, 60% to 80% of patients with palpable enlargement of the kidney. In general, the greater the kidney, the renal function was worse.
④ proteinuria
Generally small, 24-hour urine does not exceed 2g. Multi-does not occur with nephrotic syndrome.
⑤ hypertension
Solid cyst oppression of the kidneys, causing renal ischemia, renin secretion increased, causing high blood pressure. With normal renal function, more than 50% of patients withhypertension, renal dysfunction, higher incidence of hypertension.
The ⑥ renal dysfunction
Cystic space-occupying, oppressive, a significant reduction in the normal kidney tissue,and progressive loss of renal function.
