Prospective randomized comparison between transperitoneal laparoscopic pyeloplasty and retroperitoneoscopic pyeloplasty for primary ureteropelvic junction obstruction . 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 , χ2 test , and Mann-Whitney U test for independent groups , and P < .05 was considered statistically significant . RESULTS The total operative time and intracorporeal suturing time were significantly higher in group II than in group I ( P < .001 ) . The visual analog scale score for pain on postoperative day 1 and the requirement for tramadol were significantly higher in group I than in group II ( P=.004 ) . The hospital stay and the rate of temporary ileus were significantly greater ( P < .036 and P < .02 , respectively ) in group I than in group II . The success rate of transperitoneal laparoscopic pyeloplasty versus retroperitoneoscopic laparoscopic pyeloplasty was 96.4 % versus 96.6 % with a mean follow-up period of 30.75±4.85 months versus 30.99±5.59 months ( P < .88 ) . CONCLUSION Transperitoneal laparoscopic pyeloplasty is associated with significantly greater postoperative pain , a higher tramadol dose , a higher rate of ileus , and a longer hospital stay in comparison with retroperitoneoscopic laparoscopic pyeloplasty . Although the operative time for retroperitoneoscopic laparoscopic pyeloplasty is significantly longer , the success rate remains the same for both procedures .
