Purpose

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.

Intervention Model Description
Subjects will be taught to perform self-catheterization prior to prolapse repair or incontinence surgery; voiding data will be collected on the participant's first void after surgery. Participants will be discharged home to perform self-catheterization until post-void residual is less than half the volume voided on 2 sequential voids to assess actual voiding function, and this data will be used to calculate the diagnostic accuracy of pre-determined combinations of the TOV parameters.

Experimental
PVR-based home self-catheterization
Patients will learn to self-catheterize preoperatively prior to urogynecology surgery requiring trial of void. First post-operative void will be used to collect basic information about voiding function. All participants will leave the hospital and self-catheterize until they achieve two sequential voids with post-void residual (PVR) less than half the volume voided. The cases of urinary retention captured with abnormal PVR will be used to compare the diagnostic accuracy of several commonly-used, pre-defined parameters for trial of void.

Detailed Description

Patients will learn to perform self-catheterization ('clean intermittent catheterization', or CIC) preoperatively; after surgery, the investigators will collect a range of voiding parameters used during different TOV protocols (including minimum voided volume [MVV], post-void residual via bladder scanner [PVR], subjective force of urinary stream [sFOS]). Patients will discharge home to perform CIC until two sequential post-void residuals of less than half the volume voided have been achieved. The rate of voiding dysfunction and resulting PVRs will be used to compare the diagnostic accuracy of the perioperative voiding parameters to predict need to perform CIC and post-operative urinary retention.
