Azoturia
Excess urea in the urine.
Myoglobinurea
Presence of muscle protein in urine that indicates severe muscle damage
Crystalluria
Crystals excreted in the urine that cause kidney irritation
Examples of crystalluria
FUS & FLUTD
True hemoglobinura
Hemoglobin from RBC’S that hemolyzed within the vascular system; deadly
Example of true hemoglobinura
DIC- dissimulated intra vascular coagulation
False hemoglobinura
More common; hemoglobin from RBC’S that hemolyzed within the urinary bladder
What causes false hemoglobinura
Bacteria
Glucosuria, glycosuria, dextrosuria
Glucose in the urine
What causes Glucosuria, glycosuria, dextrosuria
Renal tubules may not be absorbing glucose completely
Isosthenuria
Maintenance of constant concentration of urine, regardless of changes of osmotic pressure in blood
What causes Isosthenuria
USG approaches that of the glomular filtrate; chronic renal disease

When is Ketonemia seen
With high fat diets, starvation, long term anorexia, and impaired liver function
Ketonuria

When is Ketonuria seen
With diabetes mellitus; result of fat being broken down to meet animals energy needs
Pyuria

Urolith
Calculi in urinary tract
Micturition
Act of urinating
Cystitis
Inflammation of bladder due to infected kidney or urethra
Nephritis
Inflammation of kidney; may involve glomerulus, tubule, or interstitial renal tissue
FUS
Feline urologic system. Ex- FLUTD or idiopathic steryl cystitis
FUS C.S.
Hematuria, disuria, partial or complete obstruction of urinary tract by uroliths
Renal glomerulus
Mass of capillaries that bring blood to the nephron
Anuria
Without urine; sign of kidney failure
Polyuria
Formation and excretion of large volumes of urine
Oliguria
