Pediatric standard and robot-assisted laparoscopic pyeloplasty: a comparative single institution study

Area of Science:

• Pediatric Urology
• Minimally Invasive Surgery
• Surgical Technology

Background:

• Ureteropelvic junction obstruction is a common cause of congenital hydronephrosis in children.
• Laparoscopic pyeloplasty has become a standard surgical approach.
• Robot-assisted surgery offers potential advantages in complex minimally invasive procedures.

Purpose of the Study:

• To compare the outcomes of standard laparoscopic pyeloplasty versus robot-assisted laparoscopic pyeloplasty in pediatric patients.
• To evaluate operative time, hospitalization, and success rates for both techniques.

Main Methods:

• Retrospective cohort study of children undergoing either standard or robot-assisted laparoscopic pyeloplasty for ureteropelvic junction obstruction.
• Data collected on operative time, hospitalization, narcotic use, followup duration, and clinical/imaging outcomes.
• Successful outcome defined by symptom resolution and improved or stable hydronephrosis/renal function.

Main Results:

• Robot-assisted laparoscopic pyeloplasty had a significantly shorter median operative time (209 vs. 298 minutes, p=0.008).
• Hospitalization and narcotic use were similar between the groups.
• Both techniques demonstrated high success rates, with symptom resolution in 100% of robot-assisted and 87.5% of standard cases, and comparable improvements in hydronephrosis.

Conclusions:

• Robot-assisted laparoscopic pyeloplasty and standard laparoscopic pyeloplasty are both effective for pediatric ureteropelvic junction obstruction.
• Robot-assisted approach offers a reduced operative time with comparable success and complication rates.
• The choice of technique should consider patient factors and surgeon expertise.
