① waist, abdominal discomfort or pain: The reason is that the tension
increases due to kidney enlargement and expansion of the renal capsule, the
renal pedicle by traction, or to adjacent organs caused by compression. In
addition, kidney polycystic kidney water content, become heavy, falling traction
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: 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 number of arterial pressure to increase co-infection, so that the
wall of blood vessel rupture due to 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: small, 24-hour urine does not exceed 2g. Multi-does not occur
with nephrotic syndrome.
⑤ hypertension: Solid cyst oppression kidney, causing renal ischemia, so that
the increase in renin secretion caused by high blood pressure. With normal renal
function, more than 50% of patients with hypertension, renal dysfunction, higher
incidence of hypertension.
⑥ renal insufficiency: due to the cystic space-occupying, oppression, and
normal kidney tissue was significantly decreased.
