Robot-assisted laparoscopic pyeloplasty: Multi-institutional experience in infants

Area of Science:

• Pediatric Urology
• Minimally Invasive Surgery
• Robotic Surgery

Background:

• Robot-assisted laparoscopic pyeloplasty (RALP) is increasingly adopted by pediatric urologists.
• Limited data exists on RALP specifically in infants, presenting unique surgical challenges.
• This study addresses the safety and efficacy of RALP in infants.

Purpose of the Study:

• To evaluate the operative experience and outcomes of RALP in infants (≤1 year old).
• To assess the safety and efficacy of RALP in this pediatric population.
• To discuss technical considerations for performing RALP in small patients.

Main Methods:

• Multi-centered observational study.
• Data collected from 60 infants (≤1 year old) undergoing RALP between 2006-2012.
• Primary outcome: resolution of hydronephrosis; Secondary outcomes: surgical time, complications.

Main Results:

• 91% of patients showed resolution or improvement of hydronephrosis.
• Mean surgical time was 3 hours 52 minutes.
• 11% of patients experienced intra-operative or immediate post-operative complications.

Conclusions:

• RALP demonstrated a 91% success rate and an 11% complication rate in infants.
• These outcomes are comparable to open pyeloplasty series.
• While advantages of robotic assistance in infants require further study, this cohort is encouraging.
