Ectopic ureterocele in adults with a comparison of the anomaly in children.

Ectopic ureteroceles, while not uncommon in children, have been reported only rarely in adults. We present five adults with ectopic ureteroceles with emphasis on the varied clinical and radiographic manifestations. These findings were compared with those in 32 children with ectopic ureterocele. It was found that the clinical presentation differed in adults and children, but the radiological findings were similar. The diagnosis was in some cases delayed for many years. The anomaly could not be detected by imaging means in two of five adults and eight of 32 children, and was found only at surgery.
