Intradetrusor Onabotulinumtoxin A (Botox) at the Time of Transurethral Resection of the Prostate or Transurethral Waterjet Ablation of the Prostate for Mixed Lower Urinary Tract Symptoms
What this study is about
Patients with longstanding obstructive lower urinary tract symptoms (LUTS) due to benign prostatic hypertrophy (BPH) can also develop symptoms of overactive bladder syndrome (OAB). Transurethral resection of the prostate (TURP) and Transurethral Waterjet Ablation of the Prostate (Aquablation) are amongst the gold standard surgical treatments for BPH.
View original scientific description
Patients with longstanding obstructive lower urinary tract symptoms (LUTS) due to benign prostatic hypertrophy (BPH) can also develop symptoms of overactive bladder syndrome (OAB). Transurethral resection of the prostate (TURP) and Transurethral Waterjet Ablation of the Prostate (Aquablation) are amongst the gold standard surgical treatments for BPH. However, in the immediate post-operative period, TURP and Aquablation can also include OAB-like symptoms, including urinary frequency and urgency. For men with baseline OAB symptoms, this initial worsening of symptoms can be distressing. Botox is an FDA approved medication with on-label indications to treat overactive bladder. The purpose of this study is to evaluate the outcomes of men who have Botox concurrent with their TURP or Aquablation.
Interventions
OTHER
Survey using a questionnaire.
* 1 week post-operative visit for: trial of void, to assess for rates of postoperative urinary retention. * 4 and 12 week post-operative visits for: post void residual assessment via bladder scan, AUA symptom score, PGI-I, UDI-6, and VM Post Procedure questionnaires will be administered * Hospitalization readmission rates, urinary retention episodes will also be recorded.
Primary outcome measures
To identify whether concurrent Botox and TURP or Aquablation are effective at reducing post-operative irritative voiding symptoms.
Time frame: 4 months
This will be measured using Postoperative Urinary Retention (POUR): At 1 week post-operative visit for trial of void to assess for rates of postoperative urinary retention. At 4 and 12 week post-operative visits for post void residual assessment

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
