Clinical Trial Summary

The specific aim of this trial is to determine if hydrodistention at the time of intradetrusor injection of botulinum toxin A has additional benefit in patients with refractory overactive bladder (OAB) and urgency symptoms compared to intradetrusor injection of botulinum toxin A alone.

Consented patients will be randomized to hydrodistention at a pressure of 80 cm H2O for 5 minutes, prior to the intradetrusor injection of 100 units of botulinum toxin A (hydrodistention group) or intradetrusor injection of 100 units of botulinum toxin A alone (botulinum toxin A alone group).

The primary aim will be subjective improvement measured as change from baseline at 12 weeks using the OAB-q bother subscale.

Eligibility

Inclusion Criteria:

• Women with refractory overactive bladder symptoms, failing a credible behavioral therapy intervention and medical therapy or not tolerating medical therapy. Patients who are on medical therapy will stop the medical therapy for at least 2 weeks prior to botulinum toxin A treatment in the study

• Female = 18 years old

• Ability to consent

• Ability to complete all study related items and interviews

Exclusion Criteria:

• History of intradetrusor botulinum toxin A injection

• History of or current cancer of the genitourinary or gynecology tract

• Neurogenic bladder

• Interstitial cystitis

Related Conditions & MeSH terms

• Overactive Bladder
• Urinary Bladder, Overactive

Intervention

Procedure:
• Hydrodistention
The hydrodistention will then be performed with the bladder filled at a pressure of 80 cm H2O and noted to be full as evidenced by no further influx of water into the bladder. This volume will be held in the bladder for 5 minutes.

Drug:
• Botulinum toxin-A
Intradetrusor injection of 100 units of botulinum toxin a

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Symptom Bother	The primary outcome will be measured as change from baseline at 12 weeks using the OAB-q bother subscale which consists of eight questions assessing symptom bother with a possible score from 0 to 100 with a higher score indicating greater symptom bother.	12 weeks
Secondary	Urge Urinary Incontinence Episodes	Number of UUI episodes as reported in a 3-day bladder diary at 12 weeks as measured in change from baseline.	12 weeks
Secondary	Total Number of Voids	Total number of voids reported in the 3-day bladder diary at 12 weeks as measured in change from baseline.	12 weeks
Secondary	Subjects Requiring Clean Intermittent Self-catheterization	Proportion of subjects requiring clean intermittent self-catheterization (CISC) post-operatively as reported at 2 week post-operative visit. CISC will be initiated at post-void residual volumes of > 300 mL or > 150 mL in the presence of bothersome retention symptoms.	2 weeks
Secondary	Post Void Residual Volume	Post-void residual volume (PVR) at the 2 week follow-up visit measured with catheter or bladder scan.	2 weeks
Secondary	Rate of UTI	Rate of urinary tract infection (UTI) as assessed by positive urine culture in patients having symptoms (dysuria, urgency, frequency, temperature = 38 degrees Celcius, and/or suprapubic pain) at the 2 weeks post-operative visit. Subjects who call throughout the study complaining of symptoms but are unable to give a urine culture in clinic will also be treated and reported as having had a UTI.	2 weeks
Secondary	Quality of Life Measures	Health related quality of life (HRQL) will be measured as a change from baseline at 12 weeks using the OAB-q HRQL subscale part which consists of 25 questions that assess HRQL addressing coping, concern, sleep, and social interaction where the scoring scale is from 0 to 100 with a higher score indicating a better quality of life.	12 weeks
Secondary	Patient Impression of Improvement	Patient global impression of improvement at 12 weeks as measured using the Patient Global Impression of Improvement Questionnaire (PGI-I).	12 weeks
Secondary	Patient Satisfaction	Patient satisfaction at 12 weeks as measured using Patient Satisfaction Questionnaire (PSQ).	12 weeks
Secondary	Quality of Life Measures	Subjective outcome at 24 weeks using the OAB-q	24 weeks
