Voiding dysfunction after colpectomy and urethral lengthening in transgender men.

Background: Colpectomy is a frequent part of gender-affirming surgery in transgender men. Urologic complications with these procedures can complicate and delay further management. Aim: We reviewed the rate of postoperative voiding dysfunction after colpectomy with urethral lengthening in transgender men.

Methods: We reviewed postoperative voiding in 47 transgender men (age, 19-50 years) who underwent colpectomy with urethral lengthening. Thirty-eight patients (81%) had undergone hysterectomy (36 total, 2 subtotal/supracervical) previously and 11 (23%) underwent concomitant hysterectomy or removal of the residual cervix (4 abdominal, 6 laparoscopic, 1 transvaginal). Colpectomy was done transvaginally by opening and developing laterally the vesicovaginal and rectovaginal spaces and then transecting the lateral vaginal attachments with bipolar vessel sealing. Urethral lengthening with an anterior vaginal flap was performed in the same procedure as colpectomy. A transurethral catheter was left in situ for 14 days postoperatively. Voiding dysfunction was defined as failure of spontaneous micturition after removal of the catheter at 14 days.

Results: 40/47 (85%) patients were able to void after catheter removal, 7 (15%) were not. Voiding dysfunction occurred in 3/11 (27%) patients undergoing concomitant hysterectomy or removal of a residual cervix and in 4/36 patients (11%) status post total hysterectomy. Voiding dysfunction persisted for a median of 3 months (2 days - 46 months).

Conclusions: In this series voiding dysfunction developed in 15% of transgender men undergoing colpectomy with urethral lengthening and appeared to be more common in patients undergoing concomitant hysterectomy or removal of a residual cervix than in those status post hysterectomy. Patients should be counseled accordingly.
