Improving Postoperative Efficiency: An Algorithm for Expedited Void Trials After Urogynecologic Surgery

Abstract

We propose an algorithm for void trials after urogynecologic surgery. After backfilling the bladder if voided volume is ≥200 mL, the void trial is successful and no PVR is needed; if voided volume is between 100 and 199 mL, the void trial is indeterminate and PVR is recommended; and if voided volume is <100 mL, the void trial is unsuccessful and catheterization is needed. Applying this algorithm to our study population would have eliminated the need for PVR in 85% of patients. Calculated PPVs and NPVs depend on the prevalence of voiding dysfunction in the population being studied, and therefore may be unique to our institution.
