Periurethral collagen injections for incontinence following radical prostatectomy: does the patient benefit?

Promising early results have been reported with periurethral collagen injections in the treatment of incontinence after radical prostatectomy. However, a significant proportion of patients does not benefit from this minimally invasive option. Recently, the results of longer follow-up studies have become available in some series. Investigators have also attempted to identify the prognostic factors of success. This review reports the latest advances on periurethral collagen injections in the treatment of incontinence after radical prostatectomy.
