Microscopic examination Of Urine Flashcards
Most glomerular disorders are caused by:
Immunologic disorders
Dysmorphic RBC casts would be a significant finding with
Good pasture syndrome
Acute glomerulonephritis
Henoch-Schönlein purpura
Dysmorphic RBC casts would not be a significant finding with
Chronic pyelonephritis
Occasional episodes of macroscopic hematuria over periods of 20 or more years are seen with :
IgA nephropathy
Antiglomerular basement membrane antibody is seen with
Goodpasture syndrome
Antineurophilic cystoplasmic antibody is diagnostic for:
Wegner Granulomatosis
Respiratory and renal symptoms are associated with
IgA nephropathy
Wegener granulomatosis
Henoch-Schönlein purpura
Respiratory and renal symptoms is not associated with
Goodpasture syndrome
The presence of fatty casts is associated with
Nephrotic syndrome
Focal segmental glomerulosclerosis
Minimal change disease
The presence of fatty casts is not associated with
Nephrogenic diabetes insipidus
Highest levels of proteinuria are seen with
Nephrotic syndrome
Ischemia frequently produces
Acute renal tubular necrosis
A disorder associated with polyuria and low specific gravity is:
Nephrogenic diabetes insipidus
An inherited disorder producing a generalized defect in tubular readsorption is:
Fanconi syndrome
A teenage boy who develops gout in his big toe and has a high serum uric acid should be monitored for:
Uromodulin-associated kidney disease
The only protein produced by the kidney is:
Uromodulin
Presence of renal tubular epithelial cells and casts is an indication of:
Acute tubular necrosis
Differentiation between cystitis and pyelonephritis is aided by the presence of
WBC casts
Presence of WBCs and WBC casts with no bacteria is indicative of:
Acute interstitial nephritis
End-stage renal disease is characterized by all of the following except:
Hypersthenuria
Prerenal acute renal failure could be caused by:
Massive hemmorrhage
The most common composition of renal calculi is
Calcium oxalate
Urinalysis on a patient with a severe back pain being evaluated for renal calculi would be most beneficial if it showed:
Miscroscopic hematuria
Warming of urine at 37deg C
Dissolves some crystals
Refrigeration of urine
Precipitation of amorphous urates/phosphates and other non-pathologic crystals
Centrifugation
5 minutes in 4000RCF
LPO detects
General composition of sediment
Casts
HPO indentifies
Urinary sediments
Sternheimer-Malbin stain
Most used in urinalysis
Crystal violet and Safranin O
Sternheimer-Malbin stain
Sedi stain and KOVA stain
Sternheimer-Malbin stain
Confirm.presence of triglycerides, neutral fats, and cholesterol
Lipid stains, Oil red O, Sudan III and Polarizing microscopy
Identification of bacterial casts
Gram stain
Crystal violet, Iodine, Alcohol Safranin
Gram stain
Purple/Violet
Gram(+) bacteria
Red
Gram(-) bacteria
Preferred stain for urinary eosinophils (In cases of drug-induced allergic reaction producing inflammation of the
renal interstitium)
Hansel stain
Methylene blue and Eosin Y
Hansel stain
Prussian blue stain
Stain for iron
Aids in identification of Treponema Pallidum
Dark-Field microscopy
Hyaline casts, mixed cellular casts, mucous threads and Trichomonas
Phase-Contrast microscopy
Cholesterol, oval fat bodies, fatty casts and crystals
Polarizing microscopy
Three dimensional microscopy
Interference contrast
Associated with damage to the glomerular membrane or vascular injury within the genitourinary tract
Red Blood Cell
Frequently associated with advanced glomerular damage but is also seen with damage to the vascular integrity of the urinary tract caused by trauma, acute infection or inflammation, and coagulation disorders.
Macroscopic hematuria
Critical to the early diagnosis of
glomerular disorders and malignancy of the urinary tract and to confirm the presence of renal calculi
Microscopic hematuria
Increased in urinary WBC which indicates the presence
of an infection or inflammation in the genitourinary system.
Pyuria
Drug-induced Interstitial Nephritis, UTI and renal
transplant rejection
Eosinophil
Resembles RBC
Lymphocytes
increased numbers in the early stages of renal transplant rejection
Lymphocytes
Used to enhance nuclear detail
Supravital staining/Addition of Acetic Acid
Largest cells found in urine sediment
Squamous EC
