Urinalysis 2 Flashcards
Anuria
Not producing urine
Ketonuria
Excretion of abnormally large amounts of ketone bodies in urine
Micturition
Urinating
Oliguria
Production of abnormally small amounts of urine
Pollakiuria
Frequent small voids of urine
Polyuria
Production of LOTS of urine
Proteinuria
Presence of abnormal quantities of protein in the urine
Cast
Building a mold of something
Isosthenuria
Urine whose SG is not greater or less than that of protein free plasma
Polydipsia
Abnormally great thirst
Urolithiasis
Stones in bladder or urinary tract
Urolith
Stone
Crystalluria
Crystals found in urine
Cystitis
Inflammation of bladder
Azotemia
Waste in blood
Normal amounts of erythrocytes in urine
0-3/hpf
Concentrated urine makes erythrocytes what
Shrink / crenate
Dilute urine causes erythrocytes to what
Swell
Normal amount of leukocytes in urine
0-5/hpf
Leukocytes can be contaminates of what
Lower urinary tract
Three types of epithelial cells
Squamous, transitional, renal
Squamous epithelial cells come from where and indicate what in large numbers?
Distal urethra, vagina, vulva prepuce ; not significant
Transitional epithelial cells come from where and indicate what in large numbers?
Bladder, ureters, renal pelvis, proximal urethra ; cystitis / pyelonephritis
Renal epithelial cells come from where and indicate what in large numbers?
Renal tubules ; parenchymal damage
Where are casts formed?
Lumen of distal and collecting tubules of the kidney
4 things that need to be present to form casts
⬆️salt concentration
⬆️time through tubules
Lower pH
Protein present
What 3 conditions can casts indicate
Irritation, inflammation, and degenerative kidneys
Two normal types of casts and in what amount?
Hyline and granular ; 0-1/LPF
Most common cast
Granular
Waxy casts look like what
Wider with square ends
Crystal formation is influenced by what
pH, concentration, elements from renal activity
Struvites are AKA
Triple phosphate
Struvite Crystal are most oftenly associated with what
UTI
2 crystals associated with Dalmatians
Uric acid and ammonium urate
Normal crystals found in horse and rabbit URINE
Calcium carbonate
What crystals are found with ethylene glycol toxicity
Monohydrate calcium oxolate
What is the danger of sulfonamide crystal formation
Stones can damage tubules
Kidneyworm AKA
Dioctophyma renale
Bladderworm AKA
Pearsonema plica
Quivering bacteria is AKA
Brownian movement
Many bacteria + many WBCs =
UTI
What do mucus strands indicate
Irritation
2 most common types of stones in cats and dogs
