Sonographic measurement of bladder wall thickness in healthy children

The aim of this study was to determine the ultrasonographic [US] bladder wall thickness [BWT] in normal children. In 106 children [54 boys and 52 girls, aged 8 months to 15 years] without any history and laboratory findings of bladder dysfunction or infection, US measurement of bladder points was performed with bladder filled to at least 50% of its expected capacity. The mean thickness of four bladder wall points was 1.79 +/- 0.28 mm. The mean anterior wall thickness was 1.5 +/- 0.31 mm [range 0.9-2.2 mm], posterior 2 +/- 0.36 mm [range 1.2-3.1 mm], right lateral 1.8 +/- 0.34 mm [ranges 0.8-3mm] and left lateral 1.8 +/- 0.36mm [range 1-3mm]. There was a significant difference between bladder sites [P<0.05] except between lateral sites. We recommend after measurement of four points, to compare these values with normal +/- 2SD curves according to age
