title: Rare variant of isolated lower pole hydronephrosis: primary obstructive megaureter.
abstract: Hydronephrosis in the lower pole moiety of a duplex system is relatively uncommon, usually associated with vesicoureteric reflux. We report on a patient with primary obstructive megaureter of a lower pole moiety that we believe is the first case report in the literature.
