I am a urologist from Guangzhou, China. For patients with autosomal dominant polycystic kidney disease (ADPKD) who meet surgical indications, I perform cyst decortication combined with renal capsule stripping to relieve pain, reduce hypertension, and slow the progression of renal failure.

This is intraoperative video footage. You can see abundant coffee‑colored fluid within the cysts. The cyst fluid is complicated by hemorrhage and secondary infection. When I puncture the cysts with an ultrasonic scalpel, the purulent contents are under high pressure and spray out.

Autosomal Dominant Polycystic Kidney Disease (ADPKD) cysts often exhibit the "cyst within a cyst" appearance: smaller, separate daughter cysts grow inside a larger parent cyst, forming a nested structure of mother and daughter cysts. Frequently, additional independent cysts can also be found deeper and adjacent to the main cyst.

Simple renal cysts usually present as isolated, single fluid-filled sacs. Nested structures with secondary cysts growing inside the primary cyst are extremely rare.
