Deformities of the Renal Tract in Children With Meningomyelocele and Hydrocephalus, Compared With Those of Children Showing No Such Central Nervous System Deformities

SUMMARY An analysis of deformities of the renal tract in a survey of 4, 500 necropsies in children showed an overall prevalence of renal tract deformities in 7.8 per cent. When the renal tract deformities were analysed in relation to the presence of meningomyeloceles, it was found that the incidence in the latter was 29 per cent. overall, ranging from 25 per cent. at birth to 58 per cent. at between the ages of 3 and 5 years. The types of deformity seen in children with meningomyeloceles are similar to those in children without meningomyelocele but there is an added factor of dilatation deformity developing later.
