1. Right ureter stone
   • A 6.5 x 3.3 mm stone is lodged in the mid-right ureter, around the L3 vertebral level.
   • It is blocking urine flow enough to cause mild right hydroureteronephrosis, meaning mild swelling of the ureter and kidney.
   • There is also a very tiny non-obstructing stone in the right kidney.
   Likely causes of stones: low fluid intake and concentrated urine are common contributors. Other possibilities include high salt intake, high animal-protein intake, recurrent urinary infection, high calcium/uric acid or other metabolic abnormalities, and family tendency. The stone itself is the direct reason for the mild kidney swelling, as reflected in standard urology imaging descriptions.
2. Old calcified lesion in the right lobe of the liver
   • CT describes a lesion with a thick calcified rim and additional tiny calcified foci.
   • The radiologist considers it most likely an old, healed liver abscess / granulomatous inflammatory scar.
   • The ultrasound also mentions another possibility: a calcified hydatid cyst. Hydatid disease is a parasitic infection, more likely in people with exposure to dogs/sheep or livestock areas, but imaging alone cannot confirm it.
   • This does not look like an active liver abscess on the wording provided, but it needs clinical correlation.

Are the kidney stone and liver lesion related?

What should happen next

• See a urologist promptly, ideally within a few days, for the 6.5 mm obstructing ureter stone. A stone of this size may not pass on its own and sometimes needs medicines, ureteroscopy/laser removal, or a stent depending on pain, infection, obstruction, and kidney function.
• Get urine routine/culture, serum creatinine/kidney function, CBC, and follow-up imaging as the treating clinician advises.
• Discuss the liver finding with a physician/gastroenterologist. They may compare with old scans and decide whether liver function tests, contrast imaging, or hydatid serology are appropriate, especially with relevant animal exposure.
• Drink fluids unless a clinician has restricted fluids, but fluids alone will not reliably clear an obstructing stone of this size.

Seek emergency care today if any of these occur

• Fever, chills, burning urine, or feeling very unwell
• Severe or escalating right-sided pain, repeated vomiting
• Reduced urine output
• Blood pressure drop, confusion, or weakness
