Prevalence of cystine and urate uroliths in bulldogs and urate uroliths in dalmatians.

Data were evaluated from all dogs admitted to the University of Minnesota Veterinary Teaching Hospital (UMVTH) between June 1, 1981 and Dec 31, 1991. During this period, uroliths were retrieved and analyzed from 452 of 37,574 dogs admitted. The odds that uroliths from Bulldogs were composed of cystine were 32.3 times greater than for other breeds evaluated. The odds that a Bulldog admitted was affected with cystine uroliths were 154.1 times greater than for other breeds. Cystine uroliths were retrieved only from male Bulldogs. The odds that uroliths from Bulldogs were composed of urate were 7.9 times greater than for other breeds. The odds that a Bulldog admitted was affected with urate uroliths were 43.0 times greater than for other breeds. Male Bulldogs were 14.3 times more likely to be affected with urate uroliths than were females. The odds that uroliths from Dalmatians were composed of urate were 228.9 times greater than for other breeds. The odds that a Dalmation admitted was affected with urate uroliths were 122.4 times greater than for other breeds. Male Dalmatians were 16.4 times more likely to be affected with urate uroliths than were females. Data also were evaluated from files of canine uroliths submitted to the Minnesota Urolith Center for quantitative mineral analysis between June 1, 1981 and Dec 31, 1991. During this period, 94 of 11,188 uroliths analyzed were obtained from Bulldogs and 387 were obtained from Dalmatians. The odds that uroliths retrieved from Bulldogs were composed of cystine were 40.7 times greater than for other breeds. Cystine uroliths were retrieved only from male Bulldogs.(ABSTRACT TRUNCATED AT 250 WORDS)
