Abstract

Purpose: Robot-assisted laparoscopic pyeloplasty (RALP) and laparoscopic pyeloplasty (LP) are both minimally invasive surgical options to correct ureteropelvic junction obstruction in children. There are limited data reporting surgeons' experience of switching from LP to RALP and comparing the outcomes of the two procedures.

Methods: We conducted a retrospective study on 63 consecutive children who underwent either LP or RALP by the same surgeon in a tertiary center from January 2008 to November 2016. LP had been the standard practice until January 2014 when it was replaced by RALP in short transition.

Results: Thirty-seven LP and 26 RALP were successfully performed in children aged 2 months to 16 years. There was no difference between the two groups in age, body weight, laterality, clinical presentations, preoperative imagings, primary/reoperative repairs. The overall success rates were 34/37 (91.9%) and 25/26 (96.2%) for LP and RALP, respectively (P > .05). RALP was associated with shorter length of stay (3.1 days versus 4.0 days; P = .03). Surgeon-in-training participation was greater in RALP group (P < .001). There was no difference in operative time, complication rates, and analgesic requirement between the two groups.

Conclusions: Surgeons proficient in LP can adapt quickly to RALP, achieving comparable outcomes. Robotic technology may facilitate training on minimally invasive pyeloplasty.
