What urinary tract diseases are commonly associated with dogs?
leptospirosis, lyme’s nephritis, canine herpe’s virus disease, renal dysplasia, toxic tubular necrosis, membranous glomerulonephritis, amyloidosis, urolithiasis, cystitis, transitional cell carcinoma, and renal lymphosarcoma
What lesions does acute leptospirosis cause in dogs?
hemoglobinuric nephrosis and acute tubulointerstitial nephritis
What strains of bacteria commonly cause acute leptospirosis in dogs?
L. canicola and L. icterohemorrhagica
What lesions does chronic leptospirosis cause in dogs?
azotemia, polyuria, isosthenuria, bacteriuria, enlarged nodlar kidneys, lymphogranulomatous and purulent tubulointerstitial nephritis and spirochetes within tubule lumens
What strains of bacteria commonly cause chronic leptospirosis in dogs?
L. grippotyphosa and L. bratislava
What phase of Lyme’s disease causes Lyme’s nephritis?
the chronic phase
What lesions does Lyme’s nephritis cause?
membranoproliferative glomerulonephritis +/- intersitital nephritis
What bacteria commonly causes Lyme’s nephritis?
Borrelia burgdorferi
How is canine herpesvirus disease transmitted and what dogs are commonly effected by it?
it is transmitted from bitch to pup and it usually effects puppies less than 3 weeks of age
Why are puppies less than 3 weeks of age susceptible to canine herpesvirus disease?
because they cannot regulate their body temperature at this time and the virus replicates at a lowered temperature so if the pup is neglected by the mother there is a chance that the pups temp will get too low
What type of defect is renal dysplasia?
it is a congenital/neonatal defect that is inherited in several breeds
What clinical syndrome is associated with renal dysplasia?
chronic renal failure by 3 years of age
What lesions are associated with renal dysplasia?
small, segmentally fibrotic kidneys, fetal glomeruli, metanephric ducts, fibrosis, and supernephrons
What is cystitis in dogs commonly caused by?
ascending bacterial infection
What urinary tract diseases are commonly associated with cats?
urolithiasis, feline urologic syndrome/chronic cystitis, toxic tubular necrosis, feline infectious peritonitis, renal lymphosarcoma and chronic glomerulonephritis
What are struvites in cats commonly composed of?
fine sand-like crystals and a mucous matrix
Why do male cats commonly get urethral obstruction?
because their urethra is very narrow
What lesions are associated with urolithiasis in cats?
marked urinary bladder distention with hemorrhagic cystitis
What clinical syndromes can cats with urethral obstruction acquire?
post-renal azotemia and hyperkalemia-the hyperkalemia can cause bradycardia and death
What lesions can feline urologic syndrome cause?
mild recurrent hemorrhagic cystitis
What can cause toxic tubular necrosis in cats?
ethylene glycol and easter lilies
What lesions and clinical syndroms are often associated with toxic tubular necrosis?
acute proximal convoluted tubule necrosis and acute renal azotemia/acute renal failure
What is feline infectious peritonitis?
multisystemic disease caused by FIP coronavirus
What lesions are associated with feline infectious peritonitis?
immune-mediated phlebitis/vasculitis, lymphoplasmacytic to pyogranulomatous vasculocentric exudate, and segmental, white nodular lesions along subcapsular and arcuate veins
