Abstract

The aim of this study was to report a case of polycystic kidneys and ovarian cyst in a donkey. A 24-year-old female Andalusian Breed Donkey (Extremadura, Badajoz, Spain) with weight loss syndrome chronic for date six month. The eyes had sclera ecchymoses, edema and icteric. Haematology and blood biochemistry revealed an increased leukocyte count, an elevated blood lactate concentration. Serum calcium, phosphorous, and potassium concentrations were within the normal ranges. The blood urea nitrogen and the serum glutamic oxaloacetic transaminase levels (SGOT) were 75mg/dL, and 337U/L, respectively. The necropsy revealed glade with distention severed for cumulus for urine and no change in the walk. Kidney left present atrophy severed (10 centimeters). Both kidneys were polycystic diffuse of different diameters with bilateral pyelic ectasia, ureteral dilation, lack of cortico-medullary differentiation, and sponge-like appearance of the renal parenchyma. In the sections histology demonstrated marked alteration of the normal renal parenchymal architecture, bilaterally. The renal cortices contained numerous round cysts ranging in size from 150 milimeters (mm) to 2.5 mm in diameter, lined by low cuboidal to flattened epithelium, and filled with clear fluid containing a small amount of flocculent proteinaceous debris. Both ovaries had multiple cysts. In conclusion, it was reported a case of severed polycystic kidney disease and ovarian cyst in a donkey.
