Overactive bladder (OAB) is a widespread condition characterized by urgency, urge incontinence, nocturia and excessive urinary frequency, affecting millions of people worldwide.(1) In two epidemiological studies, OAB was found in about 17% of American and European populations.(2)(3). This accounts for an estimated 33 million patients suffering from OAB in the USA. The disorder constitutes a psychological stress that impacts the patient's social life.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   Yes
Sampling Method:   Probability Sample
Study Population
Twenty healthy women (control), 20 women suffering from overactive bladder and other 20 women suffering from UTI will be selected for the study. Each control will be age matched within +/- 5 years to patients.

Inclusion Criteria:

  • Group I (OAB patients)

    1. Women with OAB, ≥18 years and premenopausal non-menstruating, not on any anticholinergic for at least two weeks before enrollment in the study.
    2. Significant urgency,i.e., having moderate or severe urgency score.
    3. Having a score > 8 on the OAB-V8 questionnaire.
    4. Urinary frequency of more than 8/day, with urgency of urination, with or without urge incontinence.
    5. Negative screening urinalysis one month after documented UTI.
  • Group II (Control)

    1. Age-matched normal volunteers (≥18 years and premenopausal non-menstruating)
    2. No Urgency.
    3. OAB-8 score < 8.
    4. No UTI.
  • Group III (UTl)

    1. Age-matched
    2. ≥18 years and premenopausal non-menstruating women with culture proven UTI.

Exclusion Criteria:

  1. Treatable genitourinary conditions that could cause incontinence
  2. Hematuria
  3. Obstructive uropathy
  4. Patients diagnosed with vaginitis
  5. History of urothelial carcinoma
  6. Urinary tract infection (except group III)
  7. Pelvic radiation.
  8. Neurogenic bladder.
  9. Renal pathology.
  10. Stress urinary incontinence.
  11. Medications.
  12. Recent history of Botox injection in the bladder (Within the last year).
