Trial Outcomes & Findings for Is 10 Injections of Bladder Botox Less Painful Than 20 Injections? (NCT NCT04124939)

NCT ID: NCT04124939

Last Updated: 2024-04-17

Results Overview

The patients will rate their level of pain from 0 as no pain to 10 as a severe pain immediately following the completion of bladder injections by selecting a whole number from 0 to 10 that represents their level of pain during the procedure.

• Recruitment status: COMPLETED
• Study phase: PHASE4
• Target enrollment: 41 participants
• Primary outcome timeframe: Post Procedure Day 1
• Results posted on: 2024-04-17

Participant Flow

154 patients found eligible for study trial participation. 89 of 154 did not meet the inclusion criteria, 14 declined participation, and 10 patients with other reasons did not participate. Total 41 patients participated with 21 in 10 injections arm and 20 in 20 injections arm.21 patients of 10 injections arm and 19 of 20 injection arm were accounted in study analysis.

Participant milestones

Measure	10 Botox Injections 100 units of Botox® (onabotulinumtoxinA) will be combined with 10 cc of sterile saline for the purpose of 10 injections. The bladder will be instilled with 2% lidocaine solution through a catheter for at least 5 minutes prior to the procedure. Cystoscopy with either a rigid or flexible cystoscope (per surgeon preference) will be performed using sterile technique. The Botox® will be injected in a grid like pattern avoiding the trigone. OnabotulinumtoxinA 100 UNT: BOTOX for injection is an acetylcholine release inhibitor and a neuromuscular blocking agent indicated for: • Treatment of overactive bladder (OAB) with symptoms of urge urinary incontinence, urgency, and frequency, in adults who have an inadequate response to or are intolerant of an anticholinergic medication.	20 Botox Injections 100 units of Botox® (onabotulinumtoxinA) will be combined with 20 cc of sterile saline for the purpose of 20 injections.
