Conditions

Overactive Bladder

Brief 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.

Interventions

PROCEDUREHydrodistention

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.

MeasureTime frameDescription
Symptom Bother12 weeksThe 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.

Subjects Requiring Clean Intermittent Self-catheterization2 weeksProportion 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.
Post Void Residual Volume2 weeksPost-void residual volume (PVR) at the 2 week follow-up visit measured with catheter or bladder scan.
Urge Urinary Incontinence Episodes12 weeksNumber of UUI episodes as reported in a 3-day bladder diary at 12 weeks as measured in change from baseline.
Quality of Life Measures12 weeksHealth 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.

Rate of UTI2 weeksRate 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.
