Sponsor: Arbor Research Collaborative for Health

View on ClinicalTrials.gov

Summary

The purpose of this study is to define and characterize important subtypes of patients with urinary urgency to improve our understanding of the pathophysiology, risk factors, experiences, and comorbidities to lay the foundation for more effective treatment by focusing on the most bothersome and difficult to treat symptoms of urinary urgency and urgency urinary incontinence.

Interventions

OTHER

Observational

Treatment: Up to five interactions: In-person visits at Baseline, 3 months, and 12 months after initial visit, and phone/online interaction at 6 months and 9 months after initial visit. Each in-person follow up visit is expected to last up to 2 hours and each phone/online interaction is expected to last up to 1½ hours. Answering questions about your general health and urinary symptoms - may be done remotely Physical exam Completing Self- Reported Measures questionnaires - may be done remotely Completing voiding/intake and food diaries, either online or on paper Weekly text message survey regarding symptom and treatment changes Biosample collection: At baseline: Up to 4 tablespoons of whole blood, dried blood spots, and urine At baseline: Whole blood will be collected with other biospecimens At 3 months: Up to 4 tablespoons of blood, dried blood spots and urine At 12 months: Dried blood spots

OTHER

Observational Controls

One in-person visit that is expected to last up to 2 hours Answering questions about your general health and urinary history Physical exam Completing Self- Reported Measures questionnaires Completing voiding/intake and food diaries, either online or on paper Biosample collection of up to 4 tablespoons of whole blood, dried blood spots, and urine

OTHER

Central Sensitization

One in-person visit expected to take up to 30 minutes, that include: Segmental Mechanical Hyperalgesia - a hand-held device with a small flat rubber surface will be placed above the pubic bone and forearm, and will apply pressure. Participant will be asked about the intensity and unpleasantness that they experience. Pinprick Temporal Summation - participant will receive tactile stimulation by a pointed skin probe ("pinprick stimulator") being placed above the pubic bone and forearm. Participant will be asked to rate the sensation they are feeling. Current treatment information including prior surgery or procedures, medication use, other current treatment/therapy used at the time of the visit. Self-reported measures questionnaires

OTHER

Physical Activity and Sleep Tracker

A physical activity and sleep monitor (Fitbit Charge 3 or similar) will be worn for a 2 week period starting at baseline prior to treatment and again at 3 months. During each 2 week period: The Fitbit will be worn both day and night to collect the most information. Text message reminders to wear the Fitbit will be sent. Daily text messages asking the number of nighttime voids you had.

Organ-Based

One in-person visit involving: Urethral vibratory sensation threshold Urethral Pressure Profilometry Cystometry Uroflowmetry Lidocaine Pre-Treatment Cystometry

Qualitative Assessment of Patients with Urinary Urgency

Participation will include two interviews with a research assistant over the phone and are expected to take up to 60 minutes for each interview. The first interview will be done within four weeks from enrollment, before the start of treatment. The interview will include questions about participant's urinary urgency, including symptoms experienced, the onset of symptoms and other factors that affect urgency. Approximately three months after the start treatment the participant will be interviewed again. This interview will cover changes in symptoms and experience with treatment, such as side effects and satisfaction with treatment.
