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
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.
