Long-term outcomes of robotic-assisted laparoscopic pyeloplasty for unilateral ureteropelvic junction obstruction in infants

jpedsurg.org

This study aims to assess the long-term outcomes of robotic-assisted laparoscopic pyeloplasty (RALP) for the treatment of ureteropelvic junction obstruction (UPJO) in infants under 3 months of age, and to compare these outcomes with those of infants aged 3–12 months.

In brief

This study evaluates long-term surgical outcomes of robotic-assisted laparoscopic pyeloplasty in very young infants (under 3 months) with ureteropelvic junction obstruction, comparing results with older infants aged 3-12 months. The research addresses the safety and efficacy of minimally invasive robotic techniques in this vulnerable patient population.

RALP is feasible in infants <3 months for UPJO, with outcomes comparable to older infants (3-12 months).
Long-term success rates of RALP for infant UPJO remain high across both age groups studied.
Early surgical intervention with RALP does not appear to compromise outcomes in very young infants.
Robotic approach offers minimally invasive option for complex reconstructive surgery even in smallest patients.
