TRCa calculations (using the values of plasma ultrafiltrable Ca and urinary Ca) revealed impaired renal Ca handling in 14/32 patients with transplanted kidneys. TRCa improved in relationship with the increment in renal transplant function, and was within the normal range in all patients with GFR above 50 ml/min. There was a positive correlation between serum Ca and TRCa; hypocalcaemia was found in 9 patients and hypercalcaemia in 3. In the majority of hypocalcaemic patients TRCa impairment was discovered, however, pathologically decreased serum Ca values were found in only one half of the patients with impaired TRCa. In most hypocalcaemic patients the concomitant renal transplant insufficiency, hyperphosphataemia and/or insufficient dietary Ca intake seemed likely to have contributed to serum Ca depletion.
肾小管钙重吸收（TRCa）计算（使用血浆可超滤钙和尿钙值）显示，32例肾移植患者中有14例存在肾钙处理受损。TRCa随着肾移植功能的改善而提高，在所有肾小球滤过率（GFR）高于50 ml/min的患者中均在正常范围内。血清钙与TRCa之间存在正相关；9例患者出现低钙血症，3例出现高钙血症。在大多数低钙血症患者中发现了TRCa受损，然而，在TRCa受损的患者中只有一半发现血清钙值病理性降低。在大多数低钙血症患者中，同时存在的肾移植功能不全、高磷血症和/或饮食中钙摄入不足似乎是导致血清钙消耗的原因。
