AB - Purpose. To determine the association between the two methods of obtaining current perception thresholds (CPTs) in the lower urinary tract (LUT). Materials and Methods. Twenty-one women undergoing pelvic surgery underwent CPT determinations of the urethra. CPTs were measured at 2,000, 250, and 5 Hz (corresponding to A-β, A-δ, and C fibers, resp.) both pre- and postoperatively. Threshold values were obtained in all patients by using the method of limits and the method of levels. Results. CPT values obtained by using the method of levels and the methods of limits were highly correlated at all frequencies before and after surgery (ρ=0.93–0.99, P<0.0001). The mean threshold values obtained by the method of levels were significantly lower at all frequencies compared with those obtained by the method of limits. Conclusions. Our findings suggest that the method of levels is more sensitive for the detection of CPTs compared to the method of limits.
