Radiographical study showed radio-opaque calculi preoperatively and post-operatively, the radiography did not contain any calculi. In two cases, the location of the calculi was in urethral and cystic and in four cases, cystic calculi were found. All the six cases were operated by incision on the urethra or placing catheter through urethral incision. No cystotomy was performed. Water samples from all pet's owner indicated that the water contained chloride, sulphate, nitrite and Iron and had some amount of hardness.
