Bulking agents help the urethra stand up to pressure and prevent urine unexpectedly leaking when under pressure from an action such as a sneeze.
Bulking agents may be an option if you are unable, or do not wish, to have other surgical treatments, or if you need, or wish, to postpone having surgery. Bulking agents are not a permanent solution and cannot cure stress incontinence because the bulking agent gradually and harmlessly dissolves over time, so the benefit is short-term.
During the operation, a surgeon uses a narrow, flexible, surgical telescope (called an endoscope) to insert a needle into, or next to, the wall of the urethra. Once inside, bulking agent is injected into the outside edges of the urethra. There are no incisions or stitches involved with this procedure.
