Transurethral bulking injections are a potential treatment option for women who experience stress urinary incontinence. Following evaluation via urodynamic testing and cystoscopy to determine the reason for a patient’s involuntary leakage, a skin allergy test may be also be provided when collagen is the bulking agent that will be used. During the actual procedure, a local anesthetic is injected vaginally into the urethra. This can cause a temporary burning sensation but will then numb the area completely. Next, the bulking agent is injected into the wall of the urethra through a needle that is introduced via a cystoscope. The cystoscope has a tiny camera at the end that produces images you will be able to see on a computer monitor. Injections may be provided at multiple sites in order to help narrow the urethral opening on all sides. After the procedure is finished, the patient will be evaluated to ensure that urination can occur and that no leakage happens when she coughs.
