Investigation--including computed tomography and ultrasonography--of the renal transplant patient with hypercalcaemia.

One hundred and eleven stable renal transplant patients were investigated, using sensitive methods, for the effect of hypercalcaemia on renal function and for the presence of nephrocalcinosis. Twenty-five patients (22.5%) were hypercalcaemic but this had no effect on renal function. Nephrocalcinosis was detected in a small percentage of patients using ultrasonography and computed tomography.
