Botulinum toxin (BTX) injections offer a safe and effective treatment for neurogenic detrusor overactivity (NDO), improving bladder control and quality of life. Repeat treatments maintain efficacy over time.
Area of Science:
- Urology
- Neurology
- Pharmacology
Background:
- Neurogenic detrusor overactivity (NDO) presents a significant challenge in managing bladder dysfunction.
- Conservative therapies often prove insufficient for NDO patients.
- Botulinum toxin (BTX) injections are emerging as a promising therapeutic option.
Purpose of the Study:
- To review the current literature on the safety and efficacy of BTX injections for NDO.
- To summarize objective and subjective outcomes of BTX therapy in NDO patients.
Main Methods:
- Systematic review of existing studies on BTX bladder injections for NDO.
- Analysis of urodynamic parameters and patient-reported outcomes.
Main Results:
- BTX injections demonstrate significant improvements in continence and quality of life.
- Objective urodynamic findings include increased bladder capacity and compliance, and reduced voiding pressures.
- The therapy is generally well-tolerated with a low-risk profile.
Conclusions:
- BTX bladder injection is a safe and effective treatment for refractory NDO.
- Benefits include both subjective patient-reported improvements and objective urodynamic changes.
- Repeat injections are feasible and maintain therapeutic efficacy, though reinnervation limits duration.

The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...
