Comparison of transperitoneal and retroperitoneal approach in robotic-assisted laparoscopic partial nephrectomy / 中华泌尿外科杂志

ABSTRACT

Objective To compare the peri-operative outcomes of patients who underwent transperitoneal or retroperitoneal robotic-assisted laparoscopic partial nephrectomy (RALPN).Methods From September 2014 to June 2015, 103 patients with kidney neoplasms who underwent RALPN were retrospectively analyzed, including 64 males and 39 females.Their mean age was 52 years(24-80 years) .Forty-four cases (29 male, 15 female) were in transperitoneal group and 59 (35 male, 24 female) in retroperitoneal group according to tumor location.The tumor size was ( 3.8 ±2.3 ) cm in transperitoneal group and ( 3.3 ± 1.4) cm in retroperitoneal group.Results Warm ischemia time (WIT) was (23.5 ±5.3) min in transperitoneal group and (19.1 ±6.9) min in retroperitoneal group (P>0.05).WIT of dorsal mass was (26.3 ±6.0) min and (19.4 ±6.5) min (P>0.05), operation duration was (127.1 ±31.3) min and (91.2 ±24.1) min (P0.05), and bowel recovery time was 2.2 days (2-4 days) and 1.3 days (1-2 days) (P <0.05), respectively.The operation duration, WIT of dorsal mass and bowel recovery time were obviously less in retroperitoneal group than those in transperitoneal group. Conclusions Both transperitoneal and retroperitoneal approach of RALPN were effective and safe for kidney neoplasms patient treatment.Compared with transperitoneal approach, retroperitoneal method could greatly shorten operation time, WIT of dorsal mass and bowel recovery time.
