Epidemiology of feline uroliths and urethral plugs
August 1st 2008In 1981, calcium oxalate was detected in only 2 percent of feline uroliths submitted to the Minnesota Urolith Center, whereas struvite was detected in 78 percent. However, beginning in the mid-1980s, a dramatic increase in the frequency of calcium oxalate uroliths occurred in association with a decrease in the frequency of struvite uroliths (Figure 1) .
Quantitative urolith analysis: A standard of practice?
December 1st 2007A quarter-century ago, analysis of uroliths removed (usually by surgery) was optional. In fact, rather than have the stones analyzed, some veterinary practitioners gave them to their clients as a topic of conversation. What about today? Is it an acceptable standard of practice to give stones retrieved from the urinary tract to owners without knowing their composition? What would be your response to a physician who gave you stones retrieved from your urinary tract? Believe it or not, we have received uroliths for analysis formed by our veterinary colleagues that were given to them by a physician. Of course, we did not perform the requested analysis because we did not want to cross the line of practicing medicine without a license. Instead, we sent them to a laboratory licensed to provide that service.
Practical Matters: Urine cortisol:creatinine ratio-the most useful normal test around
July 1st 2006Definitively diagnosing canine hyperadrenocorticism (Cushing's disease) can be exceptionally difficult because nonadrenal illness can affect the test results. However, I think that the urine cortisol:creatinine ratio (UC:Cr) serves an invaluable role in ruling out canine Cushing's disease since a dog with a normal UC:Cr almost assuredly does not have Cushing's disease.
Help clients get to the source of housesoiling problems (PDF)
September 1st 2004Feline urinary problems can frustrate both owners and veterinarians. To help us discern whether the problem is medical or behavioral or due to litter box issues, we have the owners complete this form. Inappropriate housesoiling is often due to a combination of these issues, and this form helps us narrow in on the cause and correct it. --Maureen Owen, LVT Fishers, Ind.
