Evaluation of Efficacy and Patient Satisfaction of Local Anaesthesia Versus Sedoanalgesia for Botox (R) Injection in the Urinary Bladder for the Treatment of Idiopathic Overactive Bladder
- Conditions
- Overactive Bladder
- Interventions
- Drug: intravesical botulinum toxin A injection unter local anaesthesia
- Registration Number
- NCT06437899
- Lead Sponsor
- Hospital LKH Hochsteiermark - Leoben
- Brief Summary
Patients with symptoms of overactive bladder suffer from frequent micturition, urinary incontinence and recurrent urinary tract infections. Intravesical injections with botulinum toxin A can be used as a second-line therapy for this purpose.
Intravesical botulinum toxin A injections can be performed under general anesthesia, regional anesthesia, sedoanalgesia and local anesthesia. Which form of anesthesia is used varies greatly from region to region.
As these patients are often elderly and morbid, the lowest-risk and least stressful anesthesia method should be used. The lowest-risk anesthesia method that can be used is local anesthesia. Currently, there are no guidelines that describe the use of standardized protocols for local anesthesia.
The aim of this study is to show that the use of local anesthesia in this context is not inferior to the use of sedoanalgesia.
All patients with overactive bladder symptoms who fulfill the inclusion criteria and present at the Urogynecology Outpatient Clinic of the Department of Gynecology and Obstetrics at the LKH Hochsteiermark in Leoben within 24 months will be invited to participate in the study.
The main outcome measure is pain, secondary outcome measures are quality of life, patient satisfaction, incontinence score, operation time and length of stay in the recovery room, acceptance of repeating the procedure under local anesthesia, satisfaction with the type of anesthesia method, side effects/complications and duration of inpatient stay.
The study will be randomized into 2 arms (local anesthesia/sedoanalgesia) with a 1:1 ratio to carry out the intravesical injection with botulinum toxin A.
- Detailed Description
Urinary urgency symptoms with frequent micturition, urinary incontinence, nocturia and recurrent urinary tract infections are typical complaints of women with symptoms of an overactive bladder. The level of suffering is usually very high. Social withdrawal, depressive moods, frequent antibiotic use and financial burdens due to the increased need for incontinence products can be the result. In accordance with the guideline-based treatment of idiopathic overactive bladder, intravesical injection of botulinum toxin A can be offered after unsuccessful conservative first-line and second-line treatment. Intravesical injection of botulinum toxin A has been approved for the treatment of idiopathic overactive bladder in Austria since 2013. Botulinum toxin A is a registered drug in Austria and is used for injection into the detrusor with 100IE according to its approval indication.
Intravesical botulinum toxin A injections can be performed under general anesthesia, regional anesthesia, sedoanalgesia and local anesthesia. Which form of anesthesia is used varies greatly from region to region. The effectiveness of botulinum toxin A is limited in time. Injections are repeated on average after 6-12 months. Patients are often older and often have comorbidities. Due to this and the potential need for repeated applications, the procedure should be performed under general and regional anesthesia. The use of local anesthesia, as one of the anesthesia methods mentioned, is considered to be very low-risk and the least stressful overall.
Comparing the use of local anesthesia with the use of sedoanalgesia to perform the botulinum toxin A injection is equivalent to comparing two guideline-compliant standard treatments. The confirmation of our hypothesis, namely that performing the procedure under local anesthesia is equivalent to performing it under sedoanalgesia (non-inferiority study), could serve to optimize the treatment of overactive bladder patients and contribute to an increase in the level of health protection by strengthening the role of local anesthesia in the context of this procedure as an efficient option with the elimination of all anesthetic risks and as a first-choice procedure.
All patients with overactive bladder symptoms who fulfill the inclusion criteria and present at the Urogynecology Outpatient Clinic of the Department of Gynecology and Obstetrics at the LKH Hochsteiermark in Leoben within 24 months will be invited to participate in the study.
The following examinations are carried out on all patients before inclusion, in accordance with the examination standard of our department:
* Medical history: age, micturition frequency day/night, urinary leakage, sexuality, amount drunk, frequency of urinary tract infections, previous treatments for incontinence, parity, secondary diseases (diabetes mellitus, obesity, arterial hypertension, central nervous diseases, etc), previous gynecological operations, medication
* Urogynecological examination
* Urinalysis (midstream urine)
* Urodynamics with stress test
* Micturition protocol (will be scanned)
* Standardized questionnaires to assess incontinence symptoms and quality of life
This is an open prospective randomized controlled non-inferiority study. Patients participating in the study will be randomized into 2 arms (local anesthesia/sedoanalgesia) with a 1:1 ratio. Randomization will be done electronically (www.randomizer.at).
The sample design was calculated based on a non-inferiority study with pain score evaluation as the primary endpoint.
A sample size of 39 per group, including expected drop-outs (approximately 3 per group) results in a required number of participants of 84.

- Primary Outcome Measures
Name Time Method pain assessed by numeric rating scale twentyfour hours The numeric rating scale is a pain screening tool, commonly used to assess pain severity at that moment in time using a 0-10 scale, with zero meaning "no pain" and ten meaning "the worst pain imaginable".
- Secondary Outcome Measures
Name Time Method patient satisfaction assessed with postoperative anaesthesia questionnaire twentyfour hours The postoperative anaesthesia questionnaire is a tool used to assess a patient's experience with anesthesia following surgery. It aims to gather information about the patient's perceptions of anesthesia-related outcomes and any adverse effects they may have experienced. It collects direct feedback from patients about their subjective experiences, including satisfaction and any discomfort or complications. Common sections and questions are about preoperative information, intraoperative experience, postoperative symptoms and overall satisfaction. Questions are answered with "yes" or "no".
quality of life assessed with King's Health Questionnaire three and twelve months The King's Health Questionnaire is a disease specific, self-administered questionnaire designed to assess the impact of urinary incontinence on quality of life in women. The questions in this questionnaire are to be answered using a 0-4 scale, with zero meaning "not applicable" and four meaning "very accurate".
