This document discusses occult stress urinary incontinence (SUI) associated with pelvic organ prolapse (POP). [1] Between 36-80% of women with POP have occult SUI that is only revealed when the prolapse is reduced. [2] There is no standardized method for diagnosing occult SUI. Methods to reduce the prolapse include pessaries, vaginal packs, and speculums. Cough tests during filling cystometry can identify urine leakage indicative of SUI. [3] Treatment options include postponing or performing concomitant anti-incontinence surgery with POP repair. More studies are needed to determine best practices for diagnosing and treating occult SUI.
