Robot‐assisted laparoscopic pyeloplasty in the management of lower pole ureteropelvic junction obstruction in a patient with an incomplete duplicated collecting system

Introduction The performance of robot‐assisted laparoscopic pyeloplasty has recently been increasing in frequency. However, patients with duplicated renal pelvises and ureters can present challenges. Case presentation A 71‐year‐old woman presented flank pain was diagnosed ureteropelvic junction obstruction an incomplete collecting system. Preoperative imaging did not reveal the details stenosis. Therefore, three reconstructive procedures were prepared: Anderson–Hynes procedure, end‐to‐side pyeloureterostomy, upper pole ureter to lower procedure for pole. These determined by length intact presence crossed vessels. During surgery, crossing vein severed, allowing successful reconstruction anastomosis. Conclusion evaluation preparation multiple surgical techniques are crucial systems.
