Diagnosing occult stress urinary incontinence (OSUI) prior to surgical intervention for pelvic organ prolapse (POP) repair may allow for adding an anti-incontinence procedure and thus prevent postoperative SUI.
To compare preoperative detection rates for OSUI by either a multichannel urodynamic investigation or by a plain pelvic examination.
We retrospectively evaluated the medical charts of all women who underwent urodynamic investigation prior to surgical repair of advanced POP at our institution between 1 January 2006 and 31 December 2012.
In total, 720 women underwent surgical POP repair during the study period, of whom 54 (7.5%) were diagnosed with OSUI preoperatively. Of these patients, 54 (100%) were detected by multichannel urodynamic investigation while only 27 (50%) were detected by a plain pelvic examination (P = 0.001). Bladder fullness during the pelvic examination was associated with higher detection rates for OSUI (P = 0.001). Women with OSUI who underwent concomitant tension-free vaginal tape and POP repair procedures did not develop de novo SUI or obstructive voiding symptoms (OVS) postoperatively.
Preoperative multichannel urodynamic investigation has significantly higher detection rates for OSUI than a plain pelvic examination. Utilizing this modality resulted in no cases of de novo SUI or OVS postoperatively.
