Case Report

A 35-year-old man presented for an elective vasectomy under local anaesthetic at a separate institution. During attempted ligation of the right vas deferens intraoperative bleeding and patient discomfort necessitated conversion to a general anaesthetic. Vicryl (polyglactin) haemostatic sutures were placed in the right hemiscrotum. Twelve hours post operatively the patient developed acute urinary retention. Urethral catheterisation was not possible and a suprapubic catheter was inserted. Urethroscopy revealed occlusion of the urethra at the peno-scrotal junction by visible suture material.

Following endoscopic division of the suture with a urethrotomy knife it was still not possible to access the posterior urethra due to urethral tissue damage and luminal occlusion. Retrograde urethrograms and urethroscopy three months later confirmed occlusion of the urethra at the penoscrotal junction and the patient was referred for further management. Four months following the vasectomy a buccal mucosal inlay graft urethroplasty was performed.

A subsequent urethrogram six weeks following urethroplasty revealed satisfactory urethral calibre with no anastomotic leak. The patient is now voiding normally and is symptom free seven months following the urethroplasty.

Discussion

Following an extensive literature review no other reported cases of iatrogenic urethral injury during vasectomy were found. Numerous articles have highlighted the complications of vasectomy[₁,₂,₃] with no reference to urethral injury. This case highlights the potentially serious complications of a minor surgical procedure.
