Tubal Buccal Mucosa Graft without Anastomosis of the Proximal Urethra for Long Segment Posterior Urethral Defect Repair

ABSTRACT

A 31-year-old man was referred for further management of a urethral stricture. He was a victim of a traffic accident and his urethral injury was associated with a pelvic bone fracture. He had previously undergone a suprapubic cystostomy only owing to his unstable general condition at another hospital. After 3 months of urethral injury, direct urethral anastomosis was attempted, but the surgery failed. An additional 4 failed internal urethrotomies were performed before the patient visited Chungbuk National University Hospital. Preoperative images revealed complete posterior urethral disruption, and the defect length was 4 cm. We performed a buccal mucosa tubal graft without anastomosis of the proximal urethra for a long segment posterior urethral defect. The Foley catheter was removed 3 weeks after the operation and the patient was able to void successfully. After 8 months, he had normal voiding function without urinary incontinence.
