Pathologiocal characteristics of feline urolithiasis and assessing treatment efficacy

Abstract

This study was carried out with method of perfoming screening diagnosis by ultrasound and observing urine sediment on 48 cats with clinical manifestations of urinary tract infection, such as dysuria, urinary incontinence and cloudy or bloody urine. The studied results showed that there were 37 urolithiasis cases (STN) in cats at the age of more than 1.5 years old (accounting for 77.08%). In which, there were 2 cases of kidney stones (accounting for 5.4%), 14 cases of bladder stones (37.84%) and 21 cases of stones in both bladder and urethra (56.76%). Cats with urolithiasis often manifested symptoms, such as: urinary retention, change in position when urinating, difficulty urinating, urinary incontinence, blood in urine, decreased appetite or anorexia, pain and fever.
Hematological parameters, such as: BUN, creatinine, WBC, NEU% increased clearly while (RBC) decreased slightly. The incidence of urolithiasis in cats gradually increased by the age. Male cats had higher incidence of urolitiasis than female cats. Urolithiasis cats could be treated effectively by either medical or surgical methods. However, surgical method showed better results.
