Study Notes
Urine Analysis
- Urine normally contains negligible amounts of sediments and appears clear.
- Turbidity (cloudiness) in urine can indicate a pathological or non-pathological condition.
- Organized elements or cellular elements like pus cells, RBCs, crystals, and bacteria are not normally found in urine.
- These elements may be present due to contamination or improper specimen collection.
Organized Elements
- Epithelial cells are large, flat cells found in the bladder, urethra, and vagina.
- They are commonly present in the urine of women.
- Pus cells, which are white blood cells, are often indicators of infection.
- Report their presence using words like "occasionally," "many," or "plenty," or with numbers.
- +1: Filled 1/4 of the field
- +2: Filled 1/2 of the field
- +3: Filled 3/4 of the field
- +4: Filled the entire field
- Report their presence using words like "occasionally," "many," or "plenty," or with numbers.
- Red blood cells (RBCs) can indicate inflammation or damage to the urinary tract or kidneys.
- Hypotonic urine can cause RBCs to swell and appear as ghost cells or shadow cells.
- Hypertonic urine can cause RBCs to shrink and appear as crenated cells.
- Sperm in urine is generally considered normal, but a large number of sperm can indicate epilepsy.
- Report the presence of sperm immediately to the physician.
Casts
- Casts are cylindrical structures formed in the renal tubules.
- Hyaline casts are colorless, homogenous, capsule-like structures made of a protein matrix.
- They are the most frequently found type of cast.
- These casts may indicate glomerulonephritis, pyelonephritis, chronic renal disease, congestive heart failure, stress, or exercise.
- Red blood cell casts are casts containing RBCs.
- Indicate glomerulonephritis or strenuous exercise.
Parasites
- Trichomonas vaginalis is a pear-shaped, motile, flagellated parasite.
- Often associated with “Ping – Pong” disease.
- Schistosoma haematobium can cause hematuria due to damage to the bladder.
- Enterobius vermicularis is the most common fecal contaminant.
- Wuchereria bancrofti is also a parasite frequently found in urine.
