PURPOSE: The frequency, number, and underlying associations of bladder
diverticula were studied in a pediatric population. MATERIALS AND MET
HODS: Eighty-five children with bladder diverticula (31 girls and 54 b
oys) were retrospectively identified in a pediatric genitourinary data
base of 5,084 children. RESULTS: Primary bladder diverticula were see
n in 20 children with vesicoureteral reflux and 14 children without re
flux. Fifty-one of the 85 children (60%) had associated neurogenic dys
function of the bladder (n = 26), outlet obstruction (n = 14), or a sy
ndrome (n = 9) or were postoperative (n = 2). A single child of the 26
with multiple bladder diverticula had no associated condition. CONCLU
SION: In this population, bladder diverticula were found in 1.7% of th
e children. The presence of more than one diverticulum on a side was u
sually associated with neurogenic dysfunction of the bladder, bladder
outlet obstruction, or syndromes such as Williams, Menkes, prune-belly
, or Ehlers-Danlos type 9 syndromes.
