Effect of Vibrator Use on Symptoms of Urgency Urinary Incontinence, Sexual Function, and Sleep

This is a randomized superiority trial designed to evaluate the efficacy of scheduled vibrator use as an adjunct to standard lifestyle and behavioral modifications for urgency urinary incontinence (UUI) or urgency-predominant mixed urinary incontinence (MUI). UUI is defined as involuntary urine leakage preceded by a sudden, compelling urge to void. This will be identified and confirmed by patient report and screening with urgency-related items on the Urogenital Distress Inventory-6 (UDI-6), with participants required to report urgency-related leakage at least once per week.

Eligible participants will be recruited from the Albany Medical Center Urogynecology clinic during routine outpatient visits. After informed consent and baseline assessment, participants will be randomized 1:1 to either (1) lifestyle and bladder training counseling alone (control arm) or (2) lifestyle and bladder training counseling plus scheduled vibrator use (intervention arm). Participants in the intervention group will be instructed to use a provided FDA-registered Class II wellness vibrator for 5-10 minutes at least three times per week over an eight-week period, while all participants will receive standardized bladder retraining education materials. The primary outcome measure will be change in UDI-6 score, Female Sexual Function Index (FSFI), and Brief Pittsburgh Sleep Quality Index (B-PSQI) from baseline to eight weeks. Secondary outcomes will include validated assessments of quality of life and distress, including the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12), Patient Global Impression of Improvement (PGI-I), Patient Health Questionnaire-4 (PHQ-4).

The study will be conducted at Albany Medical Center, Department of Obstetrics and Gynecology, Division of Urogynecology and Pelvic Reconstructive Surgery, following approval by the Institutional Review Board (IRB).
