Ruminant Urinary Disease - Coggle Diagram
Ruminant Urinary Disease
anatomy
kidney
bovine :cow:
lobulated
only L kidney palpable per rectum
mobile
often pushed to midline by rumen
sheep n goat :sheep::goat:
smooth kidney
palpation
:forbidden: rectal
possibele transabdominal
:female_sign:
urethra
shorter
larger diameter
obstructions rare
challenging cathterization
suburethral diverticulum on vaginal floor
particularly more difficult in :goat::sheep:
try free catch
:cow: vulvar rub
:sheep: occlude nostrils
:male_sign:
urethra
:forbidden: cathaterization
why they suck
urethral process/vermiform appendage :goat::sheep:
sigmoid flexure
urethral diverticulum
azotemia and renal failure
mechanism same as horses
post-renal disorders much more common
clinical evaluation
acute renal failure (ARF)
same mechanism as horses
drugs
oxytetracycline
NSAIDs
aminoglycosides
endotoxemia/shock
dehydration
nephrotoxic drugs
pigmenturia
hemolysis
myoglobin
rare in ruminants
toxicities
copper
ethylene glycol
oak
all parts
diarrhea will accompany
oxalate-containing plants
lamb's quarter
sorrel
vitamin D-containing plants
Cestrum
Solanum
mercury
GI and CNS signs will accompany
arsenic
gastroenteritis
diarrhea
if suspected
investigate environment and feed
necropsy
CS
nonspecific
weakness
trembling
reduced urine output
dehydration
anuria
oliguria
:microscope:
azotemia
e- derangement
hyponatremia (opposite of horse)
hypochlormia
hypo/hyperkalemia
hyperphosphatemia (opposite of horse)
urinalysis
casts +/- blood
treatment
stop drugs/toxin exposure
rumenotomy if toxin within 24hrs
activated charcoal
mineral oil
correct hemodynamic and blood chem derangement
enteral or IV fluids
diuretics
furosemide
increase renal blood flow
increase tubular flow
promote solute excretion
serial monitoring
supportive care/nutrition
prognosis
good if
early diagnosis
aggressive treatment
poor if
oxalate
heavy metal toxicity
differentiating dysuria
cystitis with pyelonephritis
systemic signs of illnes
CBC/chem changes
left kidney enlarged, painful, less lobulated
ureters possibly enlarged
abnormal kidneys on palpation or us
cystitis vs urolithiasis
both may present w dysuria
urolith
male
distended bladder
female more likely cystitis
ulcerative posthitis and vulvitis
aka pizzle rot. nice.
ulcerative infection of the mucous membrane/skin of the prepuce/vulva region caused by c.renale
usually normal flora
can proliferate madly in reponse to high urinary [urea]
C. renale
converts urea to ammonia
irritates surrounding skin
scabby ulcerations
dysuria
pain
reluctance to breed
treatment
reduce dietary protein
topical abx
systemic abx for severe cases
enzootic hematuria
chronic ingestion of bracken fern
mutagenic
irritant
carcinogenic
initially hemorrhagic cystitis
eventually
bladder neoplasia
intermittent hemorrhage
urinary tract infection
obstructive urolithiasis
