Abstract
INTRODUCTION AND HYPOTHESIS: The objective was to compare the safety and accuracy of voided volume with the standard retrograde fill approach for voiding assessment after pelvic floor surgery. METHODS: This cohort represents all women in our repository who underwent postoperative voiding assessment following procedures for pelvic floor disorders between September 2011 and June 2014. One surgeon utilized a spontaneous voiding (SV) protocol and allowed any patient who voided 150 ml or more at one time to pass the trial. The other surgeon used a retrograde fill (RF) protocol. This involved instilling the bladder with 300 ml of water or until maximum capacity immediately after the outpatient procedures and on the first postoperative day for hospitalized patients. For this protocol, a voided volume of 200 ml was considered sufficient to pass the trial. RESULTS: In this cohort, 431 women had a voiding trial with SV, and 318 with RF. The groups were similar with respect to baseline characteristics but more women in the RF group had a sling-only procedure. The failure rates of the RF (22.8%) and SV (20.0%) groups were similar (p = 0.46). Among women who passed the voiding trial, similar percentages of women returned with urinary retention and needed catheter insertion after the RF (1.6%) and SV (0.9%) methods (p = 0.65). CONCLUSION: Spontaneous voiding trial based on a minimum voided volume of 150 ml is a safe and reliable alternative to the retrograde fill method after female pelvic floor procedures.
