A Pilot Study of the Correlation Between Symptoms of Interstitial Cystitis and Urinary pH (NCT03024619)

This is a pilot study to assess the correlation between urinary pH and Interstitial Cystitis (IC) pain, with emphasis placed on exploring the type and severity of pain.
  • Other: Pain and Urinary pH
    assess the correlation between urinary pH and Interstitial Cystitis (IC) pain, with emphasis placed on exploring the type and severity of pain
    Ages eligible for Study
    18 Years to 90 Years
    Genders eligible for Study
    Accepts Healthy Volunteers
    Inclusion Criteria:
    • Women aged 18-70, with diagnosed Interstitial Cystitis (IC) and bladder pain present during week preceding enrollment.
    Exclusion Criteria:
    • Subjects who are pregnant. Subjects with current UTI or are unwilling/unable to provide consent.
    Subjects who agree to participate in the study will meet with a research team member who will review the study with them, obtain informed consent sign the HIPPA form, and provide study materials (void diary for urine quantification and recording of IC symptoms, pH strips to dip urine, "hat" to measure urine). Medical charts will be reviewed to determined how Interstitial Cystitis was diagnosed, medications, medical/surgical history, and demographics such as weight, height, BMI, race, age, marital status, education, insurance, tobacco or alcohol use. Subjects will need to dip pH paper into the urine and specific gravity reagent strip, and, by color comparison between the strips and the corresponding scales, determine and record urine pH and specific gravity. They will need to fill out the corresponding section in the voiding diary that is a survey to type and severity or pain as well as other symptoms of IC. The research team member will teach the subject how to measure the volume of their urine and how to measure and record specific gravity and pH. When not practical to record the volume of the urine (when patients are at work or away from home) they will still be asked to record pH, specific gravity and experienced symptoms. Subjects will be asked to perform the above described protocol with each episode of micturition for 3 days.

    After enrollment, subjects will complete the O'Leary-Sant pain (symptom and problem index) questionnaire, if subjects have a combined score greater than or equal to 12 they are considered to have problematic or symptomatic IC. The voiding diary that include pH and specific gravity measurement measurements, times, volume, and survey of symptoms will be returned 1-2 weeks following completion of 3 day void diary for a face-to-face meeting with a research team member. Attempts will be made to have those meetings coincide with a clinical visit to minimize study burden to the subject(e.g. - at the time of cystoscopy or follow-up visit. )
