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: Compared to the Open group, the Observation group was superior in operation time, intraoperative blood loss, first exhaust time, time of getting out of bed, hospitalization time, and analgesic demand (all P < 0.001). At 6, 12, and 24 months after operation, the improvement rate of renal function and renal pelvis dilatation in the Observation group was higher, the VAS score was lower (all P < 0.001), and the overall incidence of complications was lower (P < 0.05). During the follow-up period of 6-24 months, there was no significant difference in cyst recurrence rate between the two groups (P > 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.
