UNLABELLED: INTRODUCTION & HYPOTHESIS: Determine if treatment of urge incontinence with tolterodine results in changes in bladder and/or urethral sensation using Current Perception Threshold (CPT) testing.
METHODS: Women with >or=1 incontinence episode on 7-day diary were treated with 4 mg of long-acting tolterodine for 2-months. At baseline and 2-months, participants had CPT testing of the urethral and bladder at 3 frequencies 2000, 250, and 5 Hz. Baseline and post-treatment measures were compared using Wilcoxon Signed Rank Test.
RESULTS: Seventeen women underwent baseline CPT testing. Four discontinued medication due to side effects and did not have repeated testing. Urethral CPT at 250 Hz was lower after treatment (median 1.3 [Interquartile range .69-2.1] and .75 [.45-1.2], p = .003) and at 5 Hz trended toward a significant decrease (1.1 [1-1.9] and .84 [.32-1.1], p = .06).
CONCLUSIONS: Urethral sensitivity improves after 2-months of tolterodine, suggesting it may restore urethral sensory nerves in addition to known motor effects.
