From cheek to ureter: initial experience and learning curve of single-port robotic buccal mucosa graft ureteroplasty for complex strictures

Abstract To evaluate the initial experience of single-port robot-assisted ureteral reconstruction using a buccal mucosa graft and assess the preliminary learning curve associated with this technique. A retrospective analysis was conducted on 20 consecutive patients who underwent single-port robot-assisted ureteroplasty with buccal mucosa grafts between January 2020 and January 2026. Perioperative parameters, complications, and follow-up outcomes were recorded. Restenosis-free survival was estima
