Background: In transgender men, effects of colpectomy on voiding function are unknown, except for the incidence rates of urinary tract infections and urinary retention.Aims: To provide insight into the effect of colpectomy on Lower Urinary Tract Function (LUTF) in transgender men.Methods: A retrospective chart review was conducted among transgender men who underwent colpectomy between January 2018 and October 2020. Primary outcomes were objective and subjective changes in voiding. Secondary outcomes were transurethral catheterization length and the need for clean intermittent self-catheterization (CISC).Results: Of 132 men, 89 (67%) underwent Robot-assisted Laparoscopic Colpectomy (RaLC) and 43 (33%) Vaginal Colpectomy (VC). Maximum flow rate on uroflowmetry decreased following RaLC (mean of 29.1 vs. 38.3 mL/s, p = 0.002) and VC (mean of 29.2 vs. 40.3 mL/s, p < 0.001) after a median of four months postoperatively. An increase in total International Prostate Symptom Score was seen more frequently following VC compared to RaLC. Subjective changes were indicated by 39%, more often by men who underwent VC, of which the majority improved during the first months postoperatively. Trial without catheter (TWOC) on the first postoperative day was more successful after RaLC (79/89, 89%) than VC (24/43, 56%). Secondary TWOC was successful in 22/132 (17%) patients after a median of eight days postoperatively. In 5/132 (4%) men (three VC and two RaLC), temporary CISC was necessary for a period ranging from 5 to 21 days. The last 2/132 (2%) men after RaLC were still performing CISC at end of follow-up. Eventually, 5% (two VC and four RaLC) had to refrain from genital gender-affirming surgery with urethral lengthening due to voiding dysfunction.Discussion: After colpectomy, most objective and subjective worsening in LUTF is of a temporary nature, however, 5% had to refrain from genital gender-affirming surgery with urethral lengthening due to persistent voiding dysfunction, despite the desire to void while standing.
