Purpose: We evaluated the efficacy of collagen injections in the treatment of male urinary incontinence due to intrinsic sphincteric deficiency.Materials and Methods: A total of 88 men (mean age 68 years) with mild to severe intrinsic sphincter deficiency underwent a mean of 3.5 transurethral injections of collagen (mean total volume injected 25 ml.). Patients were subdivided into 2 groups based on use of more than 3 or 3 or fewer pads per day. Patient age, pad use before treatment, duration of leakage, number of injections, volume of collagen used and etiology of incontinence were compared for the 2 groups.Results: Of the patients 42 became nearly completely dry, 19 had substantial improvement but still required 1 to 3 pads per day, 14 consistently used fewer pads but still more than 3 per day and 13 showed no improvement. Most injections were performed with the patient under local anesthesia and no significant morbidity occurred.Conclusions: In select patients collagen injections appear to be ef...
