简要总结
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) is the gold standard treatment for BPH. However, in the immediate post-operative period, TURP 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. According to AUA guidelines, it is considered a third-line treatment therapy.
The purpose of this study is to evaluate the outcomes of men who have Botox concurrent with their TURP.
详细描述
An observational study of the effect of Botox injection at the time of TURP will be performed.
If deemed eligible, participants will be invited to participate in this trial. The International Prostate Symptom Score (IPSS) is a questionnaire that is widely used to assess LUTS in patients and assesses for incomplete emptying, frequency, intermittency, urgency, weak stream, hesitancy, and nocturia. The AUA quality of life score (AUA-QoL) asks how these symptoms affect quality of life. When administered as a combined questionnaire, this is referred to as the AUA symptom score. These scores are summed to produce an overall severity score, which can categorize patients as having mild (score 0-7), moderate (8-19) or severe (20-35) LUTS (11). The AUA symptom score is a benchmark in defining the severity of symptoms, and collection of these scores is recommended in the AUA guidelines as part of the initial management of BPH (3,4,12). The UDI-6 is a validated short form of the urogenital distress inventory, and it assesses for the impact and severity of urinary incontinence (13).
Participants will then undergo their TURP and Botox procedure with one of three surgeons in the department of Urology at Virginia Mason.
At approximately four weeks post-op, participants will have a visit with their provider. Symptoms will be assessed by re-administering the AUA symptom score, the UDI-6, PGI-I and the VM Post-Procedure Questionnaire to assess for change in symptoms as well as satisfaction with their procedure.
Participants will then have an approximate 3 month post-op visit, at which time the questionnaires will be re-administered.. Patients will have the opportunity to follow-up with their provider sooner, if needed, based on individual symptoms.

结局指标
主要结局
To identify whether concurrent Botox and TURP are effective at reducing post-operative irritative voiding symptoms.
时间窗: 1 week
At the post-operative visit: Trial of Void assessment will be used to assess for rates of postoperative urinary retention.
次要结局

- To identify whether concurrent Botox and TURP lead to higher rates of urinary retention using a bladder scan to assess the amount of residual urine in bladder post trial of void.(Four and twelve-week)
- To identify whether concurrent Botox and TURP lead to higher rates of urinary retention using the Urinary Distress Inventory, Short Form (UDI-6)(Four and twelve-week)
- To identify whether concurrent Botox and TURP lead to higher rates of urinary retention using the Patient Global Impression of Improvement (PGI-I) to assess patient observed improvement in urinary incontinence.(Four and twelve-week)
- To identify whether concurrent Botox and TURP lead to higher rates of urinary retention using the American Urological Association symptom score(Four and twelve-week)
