Modified Nondismembered Pyeloplasty for Ureteropelvic Junction Obstruction Using Axial Advancement of Renal Pelvic Flaps: Technique and Clinical Outcomes

We describe a modified technique to repair a narrow segment at the junction between the kidney and the tube draining urine to the bladder. The technique involves surgery without removing the narrow portion of tube that is blocking urine. Our results show that this is a feasible option for patients with this condition and that robot-assisted surgery resulted in faster recovery.
