Comparison of holmium laser ureteroscopic intrapelvic drainage vs.retroperitoneal laparoscopy for the treatment of peripelvlc cyst

Abstract

Objective To evaluate the clinical efficacy of holmium laser ureteroscopic intrapelvic drainage for the treatment of peripelvic cyst and to compare this technique with retroperitoneal laparoscopic renal cyst unroofing.Methods From January 2009 to December 2012,a total of 48 patients with peripelvic cysts were treated.The patients were divided into two groups randomly.The patients in group A were treated by Holmium laser ureteroscopic endo-decortication (n =25),and those in group B by retroperitoneal laparoscopic unroofing (n =23).The operative time,intraoperative blood loss,success rate,postoperative intestinal recovery and hospital stay were compared between the 2 groups.The recurrence rate was compared during the follow-up period.Results In groups A and B,the operative time was (24.12 ± 4.51) vs.(69.48 ± 14.21) min (P ＜0.05); intraoperative blood loss was (10.24 ± 3.38) vs.(49.35 ± 12.18) ml (P ＜ 0.05) ; intestinal recovery time was (13.24 ± 2.39) vs.(31.43 ± 6.99) h (P ＜ 0.05) ; hospital stay was (3.24 ± 1.42) vs.(6.04 ± 1.29) days (P ＜0.05),respectively.All the patients recovered smoothly.During the follow-up period of 6-24 months,2 cases had recurrence in each of both groups (P ＞ 0.05).Conclusion Holmium laser ureteroscopic intrapelvic drainage for the treatment of peripelvlc cyst has the advantage of mini-invasion and rapid recovery in comparison with retroperitoneal laparoscopic unroofing.
