Insights
Bladder diverticula occur in 1.7% of children, often linked to neurogenic bladder or outlet obstruction. Multiple diverticula strongly suggest underlying conditions like neurogenic dysfunction or specific syndromes.
Area of Science:
- Pediatric Urology
- Genitourinary Medicine
Background:
- Bladder diverticula are outpouchings of the bladder wall.
- Understanding their prevalence and associations in children is crucial for diagnosis and management.
Purpose of the Study:
- To determine the frequency and number of bladder diverticula in a pediatric population.
- To investigate the underlying conditions associated with bladder diverticula in children.
Main Methods:
- Retrospective review of a pediatric genitourinary database.
- Identification of 85 children diagnosed with bladder diverticula from 5,084 patients.
Main Results:
- Bladder diverticula were identified in 1.7% of the pediatric cohort.
- Associated conditions included vesicoureteral reflux (20 children), neurogenic bladder dysfunction (26 children), bladder outlet obstruction (14 children), and various syndromes (9 children).
- 60% of children with bladder diverticula had an associated condition; multiple diverticula were typically linked to neurogenic dysfunction or obstruction.
Conclusions:
- Bladder diverticula are relatively uncommon in children, affecting 1.7% of the studied population.
- The presence of multiple bladder diverticula is a significant indicator of underlying neurogenic bladder dysfunction, bladder outlet obstruction, or specific genetic syndromes.
Purpose:
The frequency, number, and underlying associations of bladder diverticula were studied in a pediatric population.
Materials And Methods:
Eighty-five children with bladder diverticula (31 girls and 54 boys) were retrospectively identified in a pediatric genitourinary data base of 5,084 children.
Results:
Primary bladder diverticula were seen in 20 children with vesicoureteral reflux and 14 children without reflux. Fifty-one of the 85 children (60%) had associated neurogenic dysfunction of the bladder (n = 26), outlet obstruction (n = 14), or a syndrome (n = 9) or were postoperative (n = 2). A single child of the 26 with multiple bladder diverticula had no associated condition.
Conclusion:
In this population, bladder diverticula were found in 1.7% of the children. The presence of more than one diverticulum on a side was usually associated with neurogenic dysfunction of the bladder, bladder outlet obstruction, or syndromes such as Williams, Menkes, prune-belly, or Ehlers-Danlos type 9 syndromes.
