Duplex collecting system diagnosed during the first 6 years of life after a first urinary tract infection: a study of 63 children.

Purpose: We determined the prevalence, anatomical variants and coexisting complications of duplex collecting systems in children with a history of UTI. Additionally, we compared the prevalence and severity of the coexisting anomalies with those found in single systems.

Materials And Methods: We reviewed the records of children younger than 6 years who were evaluated following a first UTI during a 9-year period to identify those with duplex systems.
