A minor surgical procedure called collagen periurethral injection may be recommended for treatment of male and female stress incontinence caused by urethral sphincter dysfunction. The collagen makes the area around the urethra thicker, which helps control the urine leakage.
This procedure is done in an outpatient setting, with a local or spinal anesthesia.
The procedure may need to be repeated after a few months to achieve bladder control.
Women treated with collagen injection therapy reported higher success rates than men. Potential complications include infection, urine retention, and temporary erectile dysfunction in men. Some people may have a potentially serious allergic reaction to collagen. Any potential candidate for collagen injection must have an allergy skin test prior to treatment.
