Abstract：Objective:Ureteropelvic junction (UPJ) obstruction and concomitant renal calculus disease may coexist. We present our experience with simultaneous laparoscopic pyeloplasty and pyelolithotomy in such patients. Methods:Eighteen patients underwent retroperitoneal laparoscopic pyeloplasty and concomitant pyelolithotomy at our institution. An initial dismembering of the UPJ was followed by removal of the calculi. Stones were removed with the aid of laparoscopic grasper, fluid irragation or flexible ureteroscope. The pyeloplasty was subsequently performed on all cases. Results:Complete stone clearance was possible in 13/18 patients (72%). One patient underwent subsequent extracorporeal shock-wave lithotripsy. Diuretic renography at follow-up revealed improved drainage in 16/18 (89%) patients; 2 patients had an equivocal drainage pattern but their symptoms disappeared. Conclusions:Laparoscopic pyeloplasty with concomitant pyeloplasty is feasible and effective. Laparoscopic grasper and fluid irragation can achieve satisfactory stone clearance.
