Patient's question:
What is a kidney cystDoctor's answer:
Whether simple renal cysts are congenital or acquired remains unclear regarding the etiology of renal cysts. The origin may be similar to polycystic kidney disease, although the extent might differ. On the other hand, animals can develop simple renal cysts by causing tubular obstruction and local ischemia. An isolated cyst may be located to compress the ureter, leading to progressive hydronephrosis, which can then be complicated by infection.
