Intrinsic sphincter deficiency (ISD)

Dr Caroline R Dowling, Dr Helen E O’Connell

Intrinsic sphincter deficiency (ISD) is a form of stress urinary incontinence (SUI) that occurs due to poor urethral closure function as a result of defective urethral mucosal coaptation. Clinically, it is typically associated with severe leakage of urine with minimal exertion, where increased abdominal pressure, not bladder pressure, is the expulsive force.
