The simple outpatient procedure involves the injection of a water-based gel through a small surgical needle into the tissues surrounding the urethra, the tube through which urine flows from the bladder out of the body. The gel, which is called Durasphere, is a sandy material with small carbon-coated beads that works by helping to keep the bladder neck closed by providing additional support. An incision is not needed because the needle is inserted up through the urethra with the guidance of a small videoscope. The procedure is done under light anesthetic, and there is minimal recovery for the patient.
Patients go home the same day after therapy.
But the collagen has a rapid absorption rate so the injections must be redone every four to 12 months. The new Durasphere material has a much slower absorption rate so the effects last longer, which is more beneficial to the patient. It may appeal to women hoping to avoid invasive surgery or men who have bladder control problems after prostate surgery. Of the patients who have the Durasphere treatment, about one half will need only one treatment. Nine out of 10 patients will be improved after treatment, and most will return to normal activity in a day or two after the procedure.
