Urethral Bulking Injection What is a Urethral Bulking Injection? This is an operation to treat stress incontinence (leakage of urine when you exercise, sneeze or strain). The operation involves injecting a bulking agent into the wall of your urethra (tube that carries urine) using a small telescope to treat symptoms. The bulking agent helps the urethra to make a watertight seal and to prevent urine leaking from your bladder.
