A Novel Robot‐Assisted Laparoscopic Pyeloplasty Technique to Ensure Secure Anastomosis for Lower Pole Ureteropelvic Junction Obstruction in a Patient With an Incomplete Duplicated Collecting System

This case demonstrates the feasibility of end-to-side pyeloureterostomy for UPJO with incomplete duplication using robotic techniques. Key modifications-catheter-assisted incision, anatomical mobilization, and M-shaped traction-allowed for precise anastomosis. Further case accumulation is needed to validate these strategies for similar anatomical variations.
