Intravesical Botox effectively treats refractory monosymptomatic nocturnal enuresis (MNE) in children. Over half of patients experienced significant improvement, with a well-tolerated safety profile.
Area of Science:
- Pediatric Urology
- Pediatric Nephrology
- Pharmacology
Background:
- Monosymptomatic nocturnal enuresis (MNE) affects many children, often proving resistant to standard treatments.
- Intravesical Botox is utilized for other pediatric voiding disorders, but its role in MNE requires further elucidation.
Purpose of the Study:
- To evaluate the efficacy and safety of intravesical Botox injections for children with refractory MNE.
Main Methods:
- A retrospective analysis of 22 children with MNE treated with intravesical Botox (200iU detrusor injection).
- Participants had previously failed desmopressin and often enuresis alarms or oxybutynin.
- Outcomes were categorized as complete, partial, or no response based on wet night reduction.
Main Results:
- A complete response (100% reduction) was seen in 36% of patients, with a partial response (50-99% reduction) in 32%.
- The median reduction in wet nights was 2.5 per week.
- Treatment was well-tolerated, with mild, self-resolving side effects and no serious complications.
Conclusions:
- Intravesical Botox offers an effective and safe treatment for pediatric refractory MNE.
- A significant portion of patients demonstrated a sustained positive response to the intervention.
- Botox represents a valuable therapeutic option for this challenging condition.

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...
