Description
Inclusion Criteria:
- Adult females between the ages of 18 and 80 inclusive
- Patients being treated for IC who are refractory to conservative management and oral therapy.
- willing and able to initiate catheterization post-treatment
Exclusion Criteria:
- Any history of bladder cancer, uterine cancer, ovarian cancer, vaginal cancer, urethral diverticulum, spinal cord injury, stroke, Parkinson's disease, multiple sclerosis, spina bifida, cyclophosphamide treatment, radiation treatment to the pelvis, bladder tuberculosis, genital herpes.
- Currently on or requiring anti-platelet/anti-coagulant concomitant therapy or having been on anti-platelet/ anti-coagulant therapy within the past 3 months
- Pregnancy. Pregnancy is an absolute contraindication to undergoing these procedures. Thus, as part of their normal pre-operative work up, which is standard of care, pregnancy tests are administered if they are women of child-bearing age, are sexually active, and are within 10 days of the normal menstrual period. If positive, they will be excluded as they will not undergo the procedure.
- An active urinary tract infection as shown during clean-catch urinalysis at screening visit. Subject may be re-screened if UTI is successfully treated and urinalysis is negative at rescreening.
- A history of hypersensitivity or allergy to any botulinum toxin preparation
- A post-void residual (PVR) urine volume >200mL at baseline
- Treatment with botulinum toxin during the 12 week period prior to the trial

Participant Group / ArmParticipant Group / Arm |
Intervention / TreatmentIntervention / Treatment |
|---|---|
|
Experimental: Botox upper aspect trigone
Subjects in the experimental cohort will receive a one time dose of 100 units of Onabotulinumtoxin A diluted in 10 mL of preservative free normal saline and injected in 1.0 mL boluses in a set pattern across the upper aspect of the trigone of the urinary bladder.
|
100 units of botox spread out among 10 separate injections
Other Names:
We hypothesize that injections into the trigone should be more effective in the treatment of IC than injections elsewhere in the bladder.
|
|
Active Comparator: botox periphery of trigone
Each group will receive a total of 100 units of botox spread out among 10 separate injections.
Subjects in the control group will have 10 injections made about the periphery of the trigone.
The control cohort will receive a one time dose of Onabotulinumtoxin A using the same dilution and number of boluses, but boluses will be administered at random sites on the posterior bladder wall (excluding the trigone).

Measure Description |
Time Frame |
|---|---|---|
|
The Primary Outcome Will be Assessing the Measurement of Subjective Patient Pain Using the O'Leary-Sant Symptom and Problem Indexes.
Time Frame: 30 and 90 days post treatment
|
The O'Leary-Sant is one questionnaire that assesses the severity of symptoms and the how much of a problem the symptoms cause for the patient and it provides two scores.
The scores ranges for the symptoms is 0-20 and for how bothersome the symptoms are, the score range is 0-16.
Higher scores for both denotes worse outcomes.

30 and 90 days post treatment
|
|
The Primary Outcome Will be Assessing the Measurement of Subjective Patient Pain Using the Pelvic Pain and Urinary Urgency Frequency (PUF) Questionnaire
Time Frame: 30 and 90 days post-treatment
|
The PUF questionnaire evaluates symptoms of pain and how much they bother the patient.
Two score are given and added together to produce a total score.
The score range for symptoms is 0-28 and the range for bother is 0-16.
Higher scores denotes worse outcomes.

Change in Patient Performance in Uroflowmetry.
Time Frame: 30 days and 90 days post treatment
|
Uroflowmetry is a test that measures the volume of urine released from the body, the speed with which it is released, and how long the release takes.

30 days and 90 days post treatment
