Unfortunately, in the early stages of the development of the disease, the owner’s eye does not disturbing symptoms of urolithiasis in a cat are visible. Yes and the animal itself at first may not feel painful reactions until it is about sand or stones of very small size. but an increase in the number and size of uroliths can lead to a sharp pain at every desire of the cat to go to the toilet.

In more complex cases (when the lumen of the urethra is almost completely blocked by uroliths) may be required urethrostomy is a surgical intervention, the purpose of which is the formation of a new urethral opening for urine excretion. When the diameter of the stones exceeds the diameter of the urethra itself, and the count goes to the clock, cat requires complete removal of stones by surgical method (cystotomy). Such manipulations are carried out by the animal under general anesthesia. Stones after removal are sent to chemical analysis to determine the nature of their appearance (more often total urolithiasis is due to the appearance of oxalates or struvites) – this will help you choose the right treatment. Further to the animal intravenous infusions are required to restore the body after intoxication. Antibiotics, antispasmodics are used, painkillers, anti-inflammatory and antibacterial drugs. In cases where urolithiasis is on initial stage (the cat is able to go small in the urine no impurities in the form of blood, the animal does not feel strong discomfort), doctors may suggest conservative treatment urolithiasis. His goal is to dissolve stones with special diets and the use of diuretic phytopreparations. but the conservative method will bear fruit only after a while, therefore nevertheless most often they treat urolithiasis surgically.
