An assisted suspension fixation technique in transperitoneal laparoscopic pyeloplasty for infants and young children with ureteropelvic junction obstruction: a retrospective cohort study.

ABSTRACT:

Background

Anderson-Hynes pyeloplasty is a classic and highly effective technique for treating congenital ureteropelvic junction obstruction (UPJO). Laparoscopic minimally invasive surgery (MIS) has become the preferred approach for infants and young children. However, a small working area and the complexity of reconstruction procedure pose significant challenges. This study aims to evaluate the efficacy and safety of four-point suspension fixation technique in laparoscopic dismembered pyeloplasty (LDP) for infants and young children with UPJO.

Methods

This retrospective cohort enrolled 37 infants and young children diagnosed with UPJO and underwent transperitoneal LDP between 2014 and 2020. The 37 cases were divided into two Groups based on whether suspension fixation was a
