The man who gained a stone

A 62‐year‐old male, previously on continuous ambulatory peritoneal dialysis for 1 year, received a cadaveric renal transplant. His renal failure was due to nephritis of undetermined cause. Past history consisted of hypertension and gout. He denied any history of renal stone disease or urinary infections. There was no family history of renal disease. The donated left kidney came from a 60‐year‐old male, white Caucasian smoker with a history of hypertension. There was no history of renal stone disease. HLA matching was three out of six with 0% panel reactive antibodies, and a negative T‐ and B‐cell cross‐match. The donor kidney had a single renal artery with mild atheroma and an intrarenal aortic aneurysm. Biopsy showed minor acute tubular necrosis (ATN). No glomeruli were sclerosed. Cold and warm ischaemic times were 8 h 45 min and 35 min, respectively, before revascularization. Inspection of the graft prior to its placement in the recipient showed no evidence of renal calculi.
