A 62-year-old male is seen by his general practitioner with loin pain

A 62-year-old male is seen by his general practitioner with loin pain, dysuria and haematuria. His urine dipstick is positive for blood but negative for nitrites and leucocytes. He has a past medical history of gout and irritable bowel syndrome. A computed tomography of the kidneys, ureter and bladder (CT-KUB) is requested as it is likely that the type of stones this patient is suffering from will not be visible on plain x-ray.

For the patient above, please select the type of renal stone that they are most likely to be suffering from. Select ONE option from the list above.
