Candidate brief
You are the paediatric registrar. The patient is 13 and has passed his second calcium oxalate kidney stone in two years, this time after an episode of colicky pain. His metabolic workup has confirmed idiopathic hypercalciuria with an otherwise normal blood panel. The consultant has asked you to explain to his parents why the stones keep recurring, what can be done to stop them, and what a thiazide diuretic would add. The parents are worried this will damage his kidneys and want to know if it is curable. Explain clearly, check their understanding, and agree a plan. [1]
