Laparoscopic dismembered pyeloplasty for ureteropelvic junction obstruction in children: a single-surgeon experience

Objective: The objective of this work is to evaluate the safety and short-term outcomes of laparoscopic dismembered pyeloplasty (LDP) for ureteropelvic junction obstruction (UPJO) in children, based on a single-surgeon experience using a transabdominal suspension technique. Methods: We retrospectively analyzed children with UPJO between January 2023 and October 2024 who underwent transperitoneal LDP with a transabdominal suspension maneuver performed by a single surgeon. The diagnosis was confirmed by ultrasonography and magnetic resonance urography. The outcomes were operative time, complications, hospital stay, and postoperative hydronephrosis reduction, assessed by ultrasonography at least 3 months after the operation. Results: < 0.05). All patients were free from symptoms with reduced hydronephrosis during the follow-up period. Conclusions: Transperitoneal laparoscopic dismembered pyeloplasty is a safe and effective option in the treatment of UPJO, and a transabdominal suspension technique may facilitate the procedure.
