Your ultrasound report shows a small right renal cortical cyst measuring 9.5 × 7.6 mm.
A tiny renal cortical cyst of this size is usually benign (simple cyst) and very common in adults. In most cases, it does not cause pain and does not require any specific treatment unless it has complex features (which would be mentioned in the report).
Since your
liver fibroscan is normal and the cyst is very small, the discomfort in the lower right abdomen spreading to the back is unlikely to be due to this tiny renal cyst.
More common causes of this type of pain include:
• Muscular strain
• Right-sided ureteric stone (if pain is severe/colicky)
• Intestinal causes (gas, mild colitis)
• Early appendicular irritation (if associated with fever or worsening pain)
• Lumbar spine-related pain
Next Steps
1. Get a urine routine examination to rule out infection or microscopic blood.
2. Check serum
creatinine if not already done.
3. If pain persists, consider a CT KUB (only if clinically indicated).
4. If the pain is mild and not progressive, you can take:
• Adequate hydration
• Paracetamol for pain (avoid unnecessary painkillers)
Health Tips
Seek urgent care if:
• Fever develops
• Severe worsening pain
• Vomiting
• Burning urination or blood in urine
Most small simple renal cysts are harmless and only require periodic follow-up ultrasound after 6–12 months if advised by your doctor.
