One-trocar-assisted pyeloplasty (OTAP)

Abstract

The Anderson–Hynes pyeloplasty is still the gold standard for the surgical treatment of the ureteropelvic junction obstruction in children. Laparoscopic, retroperitoneoscopic, and robotic approaches have been proposed as alternatives in order to reduce postoperative hospitalization, pain, and scars. We describe a modification of the retroperitoneoscopic technique that combines the advantages of a minimally invasive technique with the high success rate of standard dismembered pyeloplasty. We called the procedure OTAP (one-trocar-assisted pyeloplasty).
