Obstructive urolithiasis in domestic animals: A study on pattern of occurrence and etiology

Abstract

The study was conducted at surgical OPD of IVRI, Izatnagar, during a period of 3 years (2002-2005). During this period 294 cases of urolithiasis were reported, which constituted a hospital incidence of 6.22%. Caprine were the most affected species followed by buffaloes and canine. Male young caprine and buffaloes were mostly affected in the peak winter or peak summer. Rupture of the urinary bladder was very com~on in buffalo calves (48.28%) and not uncon1mon in goats (12.15%). Castration at an early age may contribute to obstructive urolithiasis in goats and cattle but most of the buffaloes and dogs were un-castrated. Feeding of concentrate diet, rich in phosphorus and extreme climatic conditions were considered as important causes of urolithiasis in ruminants.
