We report a case of a 13 year old boy with trisomy 21 syndrome who presented with recurrent urinary tract infections. A duplication of the urinary bladder was diagnosed by echography and x-ray examination with each portion of the duplicated bladder having its own uretral opening: Surgery and histology showed however the lesion to be a large diverticulum of the urinary bladder with the right uretral orifice being located in the wall of the diverticulum.
