Objectives: This study aimed to assess the efficacy, efficiency, and costs of 2 methods of trial of void (TOV) after midurethral sling (MUS) placement. Methods: A retrospective chart review was performed on women who underwent outpatient MUS between January 2013 and April 2014 by 3 urologists. Patients were excluded if they had a concomitant prolapse repair, hysterectomy, bladder/urethral injury, or any procedure that may prolong recovery room (RR) stay. Trial of void was performed by either (1) bladder instillation, catheter removal in the operating room (OR) fill with attempted void in RR, or (2) bladder instillation and catheter removal with immediate attempted void in the RR fill. Intraoperative, postoperative, and cost data were analyzed. Results: Ninety-one of 183 women (mean age, 55.9 ± 12 years; mean body mass index, 28.8 ± 5.8 kg/m2) met inclusion criteria. Eighty-three had a transobturator sling. Forty-nine (54%) had an OR fill and 42 (46%) had an RR fill; age and body mass index were similar between groups. The OR fill group had shorter median operative time (15 vs 22 minutes; P = 0.003) and median RR time (138 vs 161, P = 0.033). The OR fill and RR fill groups did not differ in TOV failure rate (3/49 vs 6/42; P = 0.29), overall mean LOS (4.96 vs 5.51 hours; P = 0.055), and median RR costs ($627 vs $678; P = 0.065). No patient had urinary retention after successful TOV. Conclusions: After MUS placement, both OR fill and RR fill TOV methods are effective and efficient with similar TOV failure rates.
