Collagen implants are injections done to help control urine leakage that is caused by a weak urinary sphincter. The sphincter is a muscle that allows your body to hold the urine in the bladder. If your sphincter muscle stops working well you will have urine leakage.

Collagen is a strong material found throughout your body in your bones, skin, and other tissues. The doctor will use animal or human collagen to help control your urine leakage.
The doctor injects collagen through a needle into the wall of your urethra, the tube that carries urine from your bladder. The collagen bulks up the urethral tissue and allows it to close up, stopping urine from leaking out of your bladder.
You may have a choice of three types of anesthesia (pain relief) for this procedure:
After you are numb or asleep from your anesthesia, the doctor will put a medical device called a cystoscope into your urethra. The cystoscope allows your doctor to see the area.
Then your doctor passes a needle through your urethra to the sphincter muscle. Collagen is injected into the sphincter through this needle. The doctor can also inject collagen into the tissue next to the sphincter.
Collagen implants are usually done in the hospital, but they also may be done in your doctor's clinic. The procedure takes about 20 to 40 minutes.
Collagen implants can help both men and women.
Men who have urine leakage after prostate surgery may choose to have collagen implants.
Women who have urine leakage and want a simple procedure to control the problem may choose to have them. These women may not want to have surgery that requires general anesthesia.
