Laparoscopic In Situ Dismembered Pyeloplasty Can Facilitate Laparoscopic Ureteropelvic Junction Obstruction Repair: A Prospective Cohort Trial.

Purpose: To describe the technique of laparoscopic in situ dismembered pyeloplasty as a modified technique during which the alignment of ureter and renal pelvis remains intact during ureteropelvic junction (UPJ) anastomosis. We also assessed intraoperative and postoperative outcomes of this modification in comparison to standard laparoscopic dismembered pyeloplasty.

Patients And Methods: Patients with significant primary UPJ obstruction without any history of abdominal surgery, high ureter insertion, or renal anomalies were considered.
