Collagen injection for intrinsic sphincteric deficiency in men: a reasonable option in selected patients.
OBJECTIVE
We evaluate transurethral collagen injection as a minimally invasive option in treating stress urinary incontinence in men and identify the prognostic factors for success or failure.


METHODS
Transurethral collagen was injected in 35 men with grades III (22) and II (13) incontinence.


RESULTS
Of the patients 7 became dry (20%), 11 improved (31.4%) and 17 were considered failures (48.6%). Abdominal leak point pressure increased and the number of pads needed decreased. In the failed group 4 patients had a history of pelvic irradiation, 5 urethral stricture disease and 3 bladder instability before injection. There was 1 case of temporary urinary retention as a complication.


CONCLUSIONS
Transurethral collagen injection for male stress urinary incontinence is a reasonable option in select patients.
