Description of Procedure  

An IV will be placed in your arm . It will deliver fluids and medicines directly into your bloodstream. A special jelly or fluid may be placed into your urethra to numb the area. If you are having spinal anesthesia, it will be injected into the spine. General anesthesia will be given through an IV.

The doctor will insert a tiny camera into your urethra. This will allow the doctor to see the bladder. The coaptite substance will be passed through the scope. It will be injected into the urethra wall near the bladder. The procedure will be repeated on the other side of the urethra. The gel will create a bulge just under the bladder.

Immediately After Procedure  

You will be monitored as the anesthesia wears off..

How Long Will It Take?
