How to prevent recurrence of laparoscopic treatment of renal cysts

Laparoscopic renal cysts are the preferred modality for those requiring surgical treatment, but if the cyst is located in a large intracortical portion (more than 50% of the volume is located in the renal cortex which I used to define as central), it is prone to recurrence after surgery. We have used partial tipped fatty capsules to fill the cystic cavity with good results and no recurrence on postoperative review. However, it is important to note that postoperative imaging reports can easily suggest a malformation, and it is necessary to explain to the patient that it is actually a fat-filled capsule. The brief method is as follows: 1. After longitudinal incision of the perirenal fascia, the fat capsule is incised longitudinally along the outer edge of the kidney; 2. The fat capsule is separated from the dorsal hiatus of the kidney; 3. The dorsal fat capsule is separated from the hiatus of the psoas muscle; 4. Depending on the location of the cyst, the fat is cut transversely in a superior or inferior position, and the fat is lifted upward or downward to obtain the tipped fat; 5.
