A substance is injected into the wall of your urethra. A special device called a cystoscope is used. The scope has a light. It looks in the bladder and urethra.
The substance bulks up the urethral tissue. This causes it to tighten. This limits urine leaking if it is the result of a weak urinary sphincter.
