Effect of anesthesia on voiding function after tension-free vaginal tape procedure.
OBJECTIVE
To determine whether the mode of anesthesia used during the tension-free vaginal tape procedure affects postoperative voiding function.


METHODS
A retrospective cohort study was performed using cases in which tension-free vaginal tape placement was the sole procedure performed. Of the 173 cases reviewed, we were able to use the data from 163. Hierarchal linear regression was used to identify independent predictors of our dependent variable: days to complete voiding. In the first block, established predictors of postoperative voiding dysfunction were entered into the model. In the second block, potential confounders of the relationship between anesthesia type and days to complete voiding identified during univariate analysis (P <.15) were entered into the model. In the third block, anesthesia type was entered into the model to determine whether it added any unique variance after controlling for previously established predictors of postoperative voiding dysfunction.


RESULTS
The mean days to complete voiding was similar in our local or regional anesthesia (n = 90) and general anesthesia groups (n = 73) (2.3 [0-21] versus 2.3 [0-14], P =.95). Our final regression model (F = 2.74, P =.011) included age, prior pelvic organ prolapse surgery, and preoperative urge symptoms and explained 22.2% of the variance in days to complete voiding. Anesthesia type did not add any predictive improvement after controlling for these variables.


CONCLUSIONS
General anesthesia, and therefore lack of a cough-stress test, does not increase the chance of postoperative voiding dysfunction associated with tension-free vaginal tape.
