Prospective randomized comparison between transperitoneal laparoscopic pyeloplasty and retroperitoneoscopic pyeloplasty for primary ureteropelvic junction obstruction

Abstract

Background and Objectives: To compare laparoscopic transperitoneal versus retroperitoneoscopic pyeloplasty for primary ureteropelvic junction obstruction in a prospective randomized manner and assess overall results with long-term follow-up. Methods: In this prospective study, from 2008 to 2012, 112 cases of primary ureteropelvic junction obstruction were randomized in a 1:1 ratio into 2 groups. Group I included patients who underwent transperitoneal laparoscopic pyeloplasty, and group II consisted of patients who underwent retroperitoneoscopic laparoscopic pyeloplasty. Demographic and clinical characteristics and postoperative and operative data were collected and analyzed. The statistical analysis was performed with the Fisher exact test, x2 test, and Mann-Whitney U test for independent groups, and P
