ABSTRACT：

Ureteropelvic junction obstruction （UPJO） is a condition characterized by the blockage of urine flow from the kidney to the ureter.With advancements in endoscopic technology，robotic-assisted laparoscopic dismembered pyeloplasty has become the dominant approach.However，approximately 10% of patients who undergo pyeloplasty still experience treatment failure，often due to long-segment proximal ureteral strictures （length greater than 2 cm）.This increases the difficulty and risk of subsequent surgeries.In the past，ileal ureter replacement or kidney autotransplantation procedures were used as alternatives to shorten or replace the ureter.However，these procedures are associated with metabolic and vascular complications and are not always preferred.A pelvic flap，which utilizes the enlarged wall of the renal pelvis，is a good solution for bridging longer segments of a diseased ureter.This article reviews the specific applications of pelvic flap pyeloplasty in the existing literature and summarizes the technical improvements and research progress of renal pelvic flap pyeloplasty in our center to provide a reference for clinical application.
