Abstract：Objective To investigate the safety and efficacy of retroperitoneoscopic pyeloplasty and traditional open pyeloplasty in the treatment of congenital ureteropelvic junction obstruction. Methods The literature databases PubMed, Cochrane Library, EM-base, CNKI, WANFANG and VIP were searched for randomized controlled trials ( RCTs) on retroperitoneoscopic pyeloplasty and tra-ditional open pyeloplasty in the treatment of congenital ureteropelvic junction obstruction from January 1st 2005 to August 1st 2015. After manual search for reference documentation classified into literature and the selection, data extraction, assessment of the RCTs which were undertaken by 2 reviewers independently according to inclusion and exclusion criteria, meta-analysis was conducted with the RevMan 5. 3 software. Results Ten studies involving 801 patients met the inclusion criteria. Meta-analysis results showed that there was no statistically significant difference in the operative time and the recurrence rate between the retroperitoneoscopic pyeloplasty and traditional open pyeloplasty (P>0. 05). Compared with traditional open pyeloplasty, the patients with retroperitoneoscopic pyeloplasty had less blood loss (95%CI-84. 46~-51. 3, P<0. 000 01), shorter postoperative hospitalization length (95%CI-5. 64~-4. 05, P<0. 000 01), and fewer postoperative complications (OR=0. 37, P=0. 007). Conclusion Retroperitoneoscopic pyeloplasty shares similar safety in the treatment of congenital ureteropelvic junction obstruction with traditional open pyeloplasty, but with the advantages of smaller trauma, faster recovery and fewer complications, which is worth of recommendation.
