Intraurethral injections of bulking agents is generally proposed as a stress incontinence treatment for older women who cannot or do not want to undergo surgery. It’s also used in cases in which perineal rehabilitation has not been effective. Bulking agents can also be used to treat chronic urinary incontinence in younger women.
The intraurethral injections of bulking agents has the effect of swelling the urethral wall. This, in turn, provides resistance against urine leakage and facilitates closure of the striated sphincter.
While this treatment provides only short-term results, it can be repeated and has the advantage of being non-invasive. When tested in clinical trials, injections of bulking agents have had positive results, with 66% of patients self-reporting that their condition improved or was resolved after a year of treatment.
