Polycystic kidney is what it is harmful to.

Polycystic kidney disease is a hereditary nephropathy, accounting for end-stage renal insufficiency of the total 5% --- 10%.
Polycystic kidney disease with age, cysts gradually increased, the earliest performance is:
        Waist pain, elevated blood pressure, kidney B-type abnormalities. If not timely control, renal cysts continue to increase, oppression of the surrounding renal function unit will cause its damage, start the process of renal fibrosis, early manifestations of urine test: protein and blood cells;
If the process of renal fibrosis has not been effectively stopped, there will be increased serum creatinine or glomerular filtration rate decreased, and ultimately the development of end-stage renal failure.
