Comparison of retroperitoneal laparoscopy with flexible ureteroscopy for treating renal pelvis cysts: superior perioperative outcome with a comparable recurrence rate

OBJECTIVES: To assess the efficacy and safety of laparoscopic excision and drainage for treating renal pelvis pericystic cysts. METHODS: A total of 100 patients with renal peripelvic cysts were included and divided into two groups according to surgical method: the Open group (receiving ureteroscopic peripelvic cyst excision and internal drainage) and the Observation group (receiving laparoscopic retroperitoneal peripelvic cyst decompression), with 50 cases in each group. The surgical data of the two groups were compared, including surgical time, intraoperative blood loss, first exhaust time, activity time, length of hospital stay, use of analgesics, renal function indicators, pelvic dilation, visual analog scale (VAS) scores for swelling compression related symptoms (lower back pain), postoperative complications, and cyst recurrence rate. RESULTS: > 0.05). CONCLUSION: Retroperitoneal laparoscopic decortication for the treatment of peripelvic cysts significantly improved perioperative outcome and safety, while demonstrating a comparable long-term recurrence rate to flexible ureteroscopic internal drainage.
