Robotic‐assisted double lingual mucosal graft ureteroplasty for multifocal ureteral strictures: Case report and technical description

Ureteroplasty with a single onlay graft for proximal ureter stricture has been widely used in the clinic. However, robotic ureteroplasty with a double lingual mucosal graft (RU-DLMG) has not been reported.The intraoperative measured ureteral stricture lengths of patient 1 were 1.8, 2.5, and 4.6 cm, and those of patient 2 were 2.5 and 3.5 cm. We performed a RU-DLMG in which the diseased ureter was incised longitudinally from the ventral side and repaired with a double lingual mucosal graft to widen the ureteral lumen. Because of the presence of a distal ureter stricture, RU-DLMG combined with ureteral reimplantation was performed in patient 1.Antegrade urography showed no obstruction of the reconstructed ureteral segment after removing the ureteral stent. The patients had no complaints about the donor site and flank pain during the 12-month follow-up.RU-DLMG appears to be a suitable option for multifocal ureteral strictures.
