Posteriorly augmented anastomotic technique with modified presuture methods in LMG ureteroplasty. (A) The ureteral stricture was incised in a longitudinal direction. (B) The ureteral stricture segment was retained, and the two ends of the healthy ureter were presutured. (C) Following the presuture procedure, the stricture segment of the ureter was excised. (D) The augmented anastomosis between the two ends of the healthy ureter. (E) Anastomosis of the donor site and the prepared LMG. (F-G) The LMG was anastomosed to the ureteral defect. (H) Omental flap wrapping the repaired ureter. LMG = lingual mucosa graft
