Insights
Vesicoureteric reflux (VUR) with reflex bladder sphincter dyssynergia (RBSD) in children is complex. Medical management with reeducation is often effective, while surgery is best reserved for persistent cases.
Area of Science:
- Pediatric Urology
- Nephrology
- Pediatric Surgery
Context:
- Reflex bladder sphincter dyssynergia (RBSD) is a condition affecting children, often presenting with vesicoureteric reflux (VUR).
- Urinary tract infections are the most common symptom, alongside voiding dysfunction.
- VUR in this cohort was typically low-grade and bilateral.
Purpose:
- To evaluate the effectiveness of various treatments for VUR associated with RBSD in pediatric patients.
- To compare surgical reimplantation, behavioral reeducation, and medical management strategies.
Summary:
- A review of 33 children with RBSD and VUR analyzed outcomes of reimplantation, reeducation, and medical treatments.
- Early reimplantation resolved VUR but led to post-operative issues in some. Medical treatment, often combined with reeducation, showed promising results in resolving VUR or improving voiding dysfunction.
- Reeducation followed by reimplantation was also utilized.
Impact:
- Highlights the complexity of managing VUR in children with RBSD.
- Suggests that surgical intervention should not be the first-line treatment.
- Emphasizes the potential role of conservative management and selective surgical use for complete reflux resolution.
Purpose:
To analyze the efficacy of the different treatments of vesicoureteric reflux (VUR) associated with reflex bladder sphincter dyssynergia (RBSD).
Patients And Methods:
The medical records of 33 children (28 girls) aged 4 to 12 years presenting reflex bladder sphincter dyssynergia and vesicoureteric reflux have been reviewed. The most common clinical symptom was urinary tract infection. Voiding dysfunction included: dysuria, urinary leak, enuresia, urgency, constipation. In most cases, vesicoureteric reflux was low grade (grade 1, n=9; grade 2, n=18; grade 3, n=6) and bilateral (n=18). Three types of treatments have been utilized: reimplantation, reeducation, medical treatment (diet, antibio-prophylaxis, anti-cholinergics).
Results:
Eleven children (2 with a solitary kidney) underwent early reimplantation which was effective on vesicoureteric reflux but 6 of them had post-operative voiding dysfunction and 5 had a new episode of urinary infection. Six had reeducation first then they underwent reimplantation. Sixteen children had an exclusive medical treatment (13 with reeducation). In 9 children vesicoureteric reflux disappeared (one child still complains of voiding dysfunction). In 7, voiding dysfunction improved but vesicoureteric reflux is still present.
Conclusion:
The management of vesicoureteric reflux associated with reflex bladder sphincter dyssynergia is complex. Surgery should certainly not be the initial treatment. However, it can remain useful if one wishes to get complete resolution of reflux.

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...
Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
