Surgeon's workshop: antegrade collagen injection: new technique for postprostatectomy stress incontinence.

Intraurethral collagen injection has become a recognized modality to treat stress urinary incontinence. The results of this procedure using the traditional retrograde endoscopic approach have generally been disappointing for men with sphincteric incontinence after radical prostatectomy. We describe a new technique of antegrade collagen injection utilizing suprapubic percutaneous bladder access to achieve simultaneous antegrade and retrograde endoscopic views of the bladder neck. This new injection technique is a promising and simple method of correcting postprostatectomy stress urinary incontinence.
