Purpose: Results of retrograde transurethral collagen injection for treatment of stress urinary incontinence have been generally disappointing for men with intrinsic sphincter deficiency following radical prostatectomy. We describe a new technique of antegrade transvesical collagen injection using suprapubic percutaneous bladder access. Materials and Methods: Between October 1994 and January 1996, 20 patients underwent antegrade collagen injection for post-radical prostatectomy stress urinary incontinence. Evaluation by pad test, urodynamics and subjective scores was performed before and after injection. Results: At a mean followup of 8.5 months 9 of 20 patients (45%) had significant subjective improvement and 5 (25%) were totally dry. Conclusions: Antegrade collagen injection is a promising and simple method of correcting post-radical prostatectomy stress urinary incontinence. Further study and longer followup are necessary to determine its precise role in the treatment of this condition.
