Laparoscopic pyeloplasty in the pediatric patient: Hand sewn anastomosis versus robotic assisted anastomosis - Is there a difference?

Purpose: 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. Materials and Methods: 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. Results: Followup was 10 to 122 weeks (average 41). All surgeries except I 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). Conclusions: 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.
