Experimental Ureteric Obstruction and Hydronephrosis in dogs: Clinical Assessment, Ultrasonographical and Hematological Findings

Abstract

The present experimental study was carried out on 12 appatrently healthy dogs which divided into two equal groups, complete unilateral uretral obstruction was performed in group A and bilateral partial obstruction was performed in group B. Both techniques were evaluated clinically, hematobiochemically and ultrasonographically for one month post obstruction. Signs of depression, aneroxia and loss of weight were observed in both groups, the animals in group A regained their appetite and activity with time. Significant increase in SUN and creatinine was observed in group A. Ultrasonographic finding showed marked increase in kidney length and width with decreased thickness of cortex and medulla in both groups. It could be concluded that bilateral partial obstruction of the ureter resulted in significant hematobiochemical and prolonged clinical signs than unilateral complete uretral obstruction.
