A 5 years old intact male dog (Labrador) was presented with a history of anorexia, stranguria, pollakiuria and dribbling of urine. Clinical examination revealed pyrexia (rectal temperature 104.6 0
F), dullness, depression, difficulty in walking and distended abdomen. Detailed clinical examination revealed enlargement of prostate and hydronephrosis. The case was successfully managed with Levofloxacin @ 500mg/ day P.O, Furosemide @2 mg/kg bwt P.O., Finasteride @ 0.1 mg/kg bwt P.O. and Pantaprazole @ 1mg/kg bwt P.O. for 15 days.
Hydronephrosis is a disease that occurs due to complete or partial obstruction of the urinary flow. This causes progressive distension of the renal pelvis and diverticula, which results in atrophy of the renal parenchyma and loss of function. The severity of the lesion depends on the time elapsed since the onset of obstruction (Santarosa et al., 2007). Enlargement of prostate is one of the most common cause of obstruction of urine outflow in dogs. Renal failure and uremia are important consequences of hydronephrosis. Consequently, the patient can exhibit signs of azotemia (Silveira et al., 2008). There fore its early diagnosis and management is of utmost importance to prevent functional damage of kidneys.
