title: Pelviureteric junction obstruction in duplex system.
abstract: An unusual case of a PUJ obstruction in the upper moiety of a duplex kidney is presented. PUG obstruction in duplex moieties is commonly seen in the lower moiety ureter and is usually due to extrinsic compression by a crossing vessel. In our case there was a long stenotic segment of the ureter draining a functionally insignificant and infected segment of the kidney. The opposite kidney was hypoplastic and non functional. An upper polar hemi nephrectomy was performed.
