Abstract:
Refractory neurogenic detrusor overactivity refers to the clinical condition that is no longer manageable by anticholinergic therapy. This condition represents a formidable task to caregivers because the treatment of urinary incontinence and adequate protection of the upper urinary tract become extremely difficult. Treatment options for refractory neurogenic detrusor overactivity include detrusor injections of botulinum toxin and intravesical instillation of vanilloid compounds, mainly resiniferatoxin, or anticholinergic drugs. If these options fail, bladder augmentation or sacral anterior root stimulation offers excellent outcomes, although at much higher costs and risks to the patients.

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...
Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
