title: The association between regional anesthesia and acute postoperative urinary retention in women undergoing outpatient midurethral sling procedures.
abstract: OBJECTIVE
  The objective of the study was to estimate the association between regional anesthesia and acute postoperative urinary retention in women undergoing outpatient midurethral sling procedures.
  
  
  METHODS
  We performed a retrospective cohort study of women undergoing outpatient midurethral sling procedures. Exposure was defined as the type of anesthesia, categorized as regional (spinal or combined spinal/epidural) or nonregional (general endotracheal, monitored anesthesia care with sedation, or local). The outcome, acute postoperative urinary retention, was defined as a failed voiding trial prior to discharge.
  
  
  RESULTS
  A total of 131 women met our inclusion criteria. Forty-two women (32%) had regional anesthesia and 89 (68%) women had non-regional anesthesia. Overall, 48 women (36.6%) had acute postoperative urinary retention. Women who had regional anesthesia had an increased odds (adjusted odds ratio, 4.4; 95% confidence interval, 1.9-10.2) of acute postoperative urinary retention compared with women receiving nonregional anesthesia.
  
  
  CONCLUSIONS
  Regional anesthesia is a risk factor for acute postoperative urinary retention following outpatient midurethral slings.
