ureteral reimplantation
Surgical procedure to correct vesicoureteral reflux by repositioning the ureter's entry point into the bladder to create a functional valve mechanism.
Full Definition
Ureteral reimplantation is a surgical procedure performed to treat vesicoureteral reflux by creating a longer submucosal tunnel for the ureter as it enters the bladder. This procedure establishes a competent ureterovesical junction that prevents retrograde flow of urine from the bladder to the kidney. Common techniques include the Politano-Leadbetter, Cohen cross-trigonal, and Lich-Gregoir approaches, which can be performed via open, laparoscopic, or robot-assisted methods. The surgery is typically indicated when medical management fails, breakthrough urinary tract infections occur, or new renal scarring develops. Success rates exceed 95% for stopping reflux, with low morbidity when performed by experienced pediatric urologists.
