Comparative study of percutaneous nephroscopy surgery and laparoscopic surgery for the treatment of simple renal cysts

Abstract

Objective To compare the efficacy and safety of percutaneous nephroscopy surgery and laparoscopic surgery for the treatment of simple renal cysts. Methods Forty patients with simple renal cysts were retrospectively analyzed from April 2012 to December 2016. They were treated by laparoscopic renal cyst unroofing decompression (laparoscopic group, 20 cases) and percutaneous nephroscopy cyst unroofing decompression (percutaneous nephroscopy group, 20 cases). The mean operation time, operation bleeding, the rate of postoperative complications (infection, fever, urine leakage), hospitalization time after operation, and follow-up data after 6 months were compared between the two groups. Results All the 40 operations were successfully performed. The clinical cure rate of two groups was 100%, the mean operation time, the operation bleeding, postoperative complications and hospitalization time after operation between the two groups were not significant difference. The postoperative drainage of percutaneous nephroscopy group was more than that of laparoscopic group, the difference was statistically significant (P<0.001). During the follow-up of 6 months, no recurrence was found in the two groups, patient's satisfaction of percutaneous nephroscopy group was better than laparoscopic group, the difference was statistically significant (P<0.001). Conclusions Percutaneous nephroscopy and laparoscopic surgery are effective and security for the treatment of simple renal cyst. At present, percutaneous nephroscopy cyst unroofing decompression is an alternative method and is worth promoting with the increase of experience.
