Urine Casts Explained
Urine casts are formed in the kidney tubules and help diagnose kidney diseases.
• Hyaline: Normal, dehydration, exercise, fever
• RBC: Glomerulonephritis, glomerular bleeding
• WBC: Pyelonephritis, interstitial nephritis
• Epithelial: Tubular injury
• Granular: ATN, CKD
• Waxy: Advanced CKD • Fatty: Nephrotic syndrome
• Broad: End-stage kidney disease
Urine microscopy provides valuable clues about kidney damage and disease severity.

What Does Your Urine Say Under the Microscope?
Urinalysis doesn't stop at the dipstick — the real story unfolds under the microscope! 🧫
Microscopic examination of urine sediment helps clinicians detect hidden pathologies that routine tests can miss.
Here's a quick breakdown:
🔴 Cells
→ RBCs = Bleeding or Stones
→ WBCs = Infection (UTI)
→ Epithelial Cells (increased) = Contamination or Renal Damage
🧪 Casts (Kidney Origin)
→ Hyaline = Normal (few)
→ RBC Casts = Kidney Inflammation
→ WBC Casts = Infection
→ Granular Casts = Chronic Kidney Disease
💎 Crystals
→ Calcium Oxalate = Kidney Stones
→ Uric Acid = Gout
→ Cystine = Genetic Disorder
🦠 Microorganisms
→ Bacteria = UTI | Yeast = Fungal Infection | Parasites = Trichomonas vaginalis
💡 Clinical Insight:
RBCs + Crystals + WBCs + Bacteria → UTI
Casts + Protein → Kidney Involvement
Every element in urine sediment tells a clinical story — it's our job as lab professionals to read it right! 🏥🔬
