Abstract
OBJECTIVE: To present our technique of laparoscopic pyeloplasty (LP) with concomitant pyelolithotomy in ureteropelvic junction obstruction (UPJO) complicated by renal calculi and compare outcome with a group of UPJO patients undergoing modified LP without coexistent calculi. MATERIALS AND METHODS: We retrospectively reviewed the charts of 51 UPJO patients undergoing modified LP from January 2013 to November 2016 at our institution. Sixteen patients were diagnosed as UPJO with coexistent ipsilateral renal calculi and underwent pyelolithotomy using our modified technique at the time of modified LP. The outcome data of this group were compared with those of 16 matched patients undergoing modified LP without calculi. RESULTS: No conversion to open surgery occurred. The mean operative time for modified LP and pyelolithotomy was 151.6 min, while the mean operative time for modified LP was 137.6 min (p = 0.21). Additionally, no differences in estimated blood loss (p = 0.96) or postoperative complications (p = 1.00) were observed between the 2 groups. The stone-free rate was 100%. During a mean follow-up of 27.1 months, there were no recurrent calculi or secondary UPJO. CONCLUSIONS: The combination of our novel flexible guiding tube and modified suture technique provides a practical and economic approach with satisfying outcome in the treating of UPJO with concomitant renal calculi.
