Optimization of Spontaneous Trial of Void in Women

Study Description

Optimization of Spontaneous Postoperative Trial of Void Among Women

Trial of void (TOV) is a diagnostic test performed on all women who undergo prolapse repair or incontinence surgery, due to the importance of diagnosing postoperative urinary retention (POUR). Incidence of POUR may be as high as 62% in some studies. Timely and accurate diagnosis is important to avoid complications such as urinary tract infection, bladder overdistension, and permanent bladder injury. Despite the frequent use of TOV, there is no gold standard for the test, and it likely has poor specificity, leading to discharge of more patients with catheter than required. This prospective cohort study will seek to establish evidence-based optimal parameters for spontaneous trial of void, a TOV modality that has merit for further evaluation given lower theoretical risk of urinary tract infection.
