Abstract
The most difficult portion of laparoscopic pyeloplasty is the intracorporeal suturing involved in the anastomosis. We identified whether there is a difference in outcomes between a laparoscopic hand sewn anastomosis and a robotic assisted anastomosis. We studied 29 patients who underwent pyeloplasty in the last 30 months, including a robotic assisted procedure in 15, a laparoscopic procedure in 12 and an aborted procedure in 2. Followup was 10 to 122 weeks (average 41). All surgeries except 1 were deemed successful by resolution of hydronephrosis on ultrasound and symptomatic criteria. Intraoperative time for robotic assisted pyeloplasty was 150 to 290 minutes (average +/- SD 223.1 +/- 46.5). Laparoscopic time was 200 to 285 minutes (average 236.5 +/- 24.1). Robotic assisted and laparoscopic anastomosis produced similar outcomes in pediatric patients who underwent pyeloplasty. Overall operative times did not vary significantly between the 2 procedures. There appeared to be no quantifiable benefits between the 2 procedures.
