However, they can be associated with significant pathology, often with long\u2010term morbidity. There is minimal literature on the review of the duplex kidney, its associated anomalies and complications. The purpose of this paper is to review our experience of imaging the spectrum of abnormalities associated with duplex kidneys in the paediatric population and correlate this with contemporary literature.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>A retrospective review of the radiology database in a tertiary paediatric centre was performed.

Ultrasound was the most common modality for early detection of these
