Stress incontinence is a common condition that involves an involuntary loss of urine; it occurs when physical movement places pressure, or stress, on the bladder. Women with this condition may experience urine leakage while coughing, laughing or participating in physical activities. Stress incontinence often occurs as a result of weakened sphincter and pelvic muscles that cannot adequately support the bladder and/or urethra. If conservative treatment is unsuccessful, a transobturator sling procedure may be performed to support a weak pelvic floor and urethral sphincter muscles. During a transobturator sling procedure, a strip of synthetic mesh tape is used to create a sling under the urethra. The transobturator sling acts like a hammock; it supports the urethra and helps keep it closed, preventing urine from leaking out. The transobturator sling procedure is safe and effective, and has a lower risk of bowel and bladder injury than other sling procedures.
