OBJECTIVES: The aim of this study was to determine whether the use of a preoperative transdermal scopolamine (TDS) patch for postoperative nausea and vomiting prophylaxis affects the success of a voiding trial after a transobturator tape sling procedure. METHODS: This study is a retrospective cohort study of adult women who underwent a transobturator tape sling procedure without concomitant procedures from February 1, 2009 through August 1, 2010. The exposed group included all eligible women who received a preoperative TDS patch. For each exposed woman, we selected the next 2 consecutive eligible women who did not receive a TDS patch to be included in the unexposed group. The primary outcome was postoperative voiding trial failure. RESULTS: We identified 35 women who met eligibility criteria and used a preoperative TDS patch, and included 70 women who did not use a preoperative TDS. A significantly higher proportion of women in the TDS patch group (54.3%) failed their voiding trial than in the group that did not receive TDS (7.1%, P ≤ 0.001). A history of an incontinence procedure, older age, and higher body mass index strengthened the association between TDS patch and voiding trial failure. The adjusted model yielded a risk ratio for voiding trial failure of 13.8 (95% confidence interval, 5.2-36.5) for women who received TDS patch compared with those who did not. CONCLUSIONS: The results of this study demonstrate that use of TDS patches for postoperative nausea and vomiting prophylaxis may negatively affect the success of voiding trials after transobturator tape sling procedures.
