Pediatric laparoscopic dismembered pyeloplasty.
We performed laparoscopic dismembered pyeloplasty in a boy with right ureteropelvic junction obstruction using 4 cannula sites, and a dismembering and reanastomosis technique identical to that used in open pyeloplasty. Interrupted sutures were placed and tied intracorporeally. A nephrostomy tube was placed under direct vision for drainage but no ureteral stent was used. Total operating time was 5 hours. The patient was discharged home 36 hours after the procedure. The nephrostomy tube was removed 10 days postoperatively after radiographic demonstration of patency and 24 hours of clamping without pain. Followup excretory urography at 6 weeks showed much less hydronephrosis and a widely patent anastomosis. Our case illustrates the technical features and feasibility of laparoscopic pyeloplasty in children, and should encourage further development of pediatric urological reconstructive laparoscopic techniques.
