First, an open\u2010ended ureteral catheter was used to guide accurate ureteral incision and secure anastomosis. Second, the dorsal pelvis of the lower pole was anastomosed to the larger\u2010caliber common ureter rather than the narrow upper pole ureter. To ensure a tension\u2010free anastomosis, the kidney and pelvis were mobilized as needed. Third, an M\u2010shaped traction technique was applied during posterior wall suturing: the lateral stay suture was tied, while the medial one was left untied and retracted with a bulldog clamp to create a groove, enhancing lumen visibility and enabling continuous posterior suturing under direct vision.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>This case demonstrates the feasibility of end\u2010to\u2010side pyeloureterostomy for UPJO with incomplete duplication using robotic techniques. Key modifications\u2014catheter\u2010assisted incision, anatomical mobilization, and M\u2010shaped traction\u2014allowed for precise anastomosis.
