STUDY OBJECTIVE: To assess the diagnostic accuracy of a retrograde voiding trial for the restoration of spontaneous voiding function after prolapse and urinary incontinence surgery and thereby determine whether the retrograde method can be a reliable alternative to the spontaneous voiding trial.
DESIGN: A retrospective cohort study.
SETTING: A single tertiary hospital in South Korea.
PATIENTS: Women who underwent operations for prolapse, urinary incontinence, or both.
INTERVENTION: Sequential voiding trials on postoperative day 1 or 2-retrograde voiding trial followed by spontaneous voiding trial.
MEASUREMENTS AND MAIN RESULTS: Of the 408 women analyzed, 278 (68.1%) passed the spontaneous voiding trial on the first day of assessment and none experienced urinary retention after a successful voiding trial. Receiver operating characteristic analyses of retrograde voiding trials evaluating voided volume (VV), postvoid residual (PVR), and voiding efficiency (VE) all demonstrated high diagnostic accuracy for restoration of spontaneous voiding function, whereas measuring PVR and VE had better discriminative ability than VV (area under the curve [95% confidence interval] = 0.93 [0.90-0.95] for PVR, 0.94 [0.91-0.96] for VE, and 0.88 [0.85-0.91] for VV; DeLong's test between PVR/VE and VV p < .01). The optimal cutoffs determined by the Youden index were 200 mL for VV (sensitivity 85.0%, specificity 78.0%), 100 mL for PVR (sensitivity 84.0%, specificity 87.0%), and 66.7% for VE (sensitivity 86.0%, specificity 88.0%).
CONCLUSIONS: The retrograde voiding trial is an accurate predictor for restoration of spontaneous voiding function after prolapse and incontinence surgery and can be a useful alternative to the spontaneous voiding trial.
