Urography in the child who wets.

Most children who wet have no underlying structural abnormality and will not benefit from urography. However, several conditions may mimic simple enuresis, and in children with clinical clues that suggest these diagnoses, urography can be confirmatory. The urogram should be conducted so as to exclude an anatomic cause for wetting. This is likely in females in the presence of a duplex collecting system, a nonfunctioning kidney, marked vaginal reflux, or a widened interpublic distance. In the urogram of a child of either sex, a spinal anomaly should be sought.
