An oral calcium loading test was performed on 55 patients with upper urinary tract stones to find absorptive or renal hypercalciuria. The mean urinary calcium excretion level of this patient group was significantly greater than that of a control group of 10 patients without abnormal upper urinary tract. Idiopathic hypercalciuria defined as more than 250 mg per day in males and more than 200 mg per day in females was observed in 13 patients; 4 patients with absorptive hypercalciuria, 6 patients with renal hypercalciuria and 3 patients of origin-unknown hypercalciuria. Five of the 6 patients with renal hypercalciuria had recurrent and/or multiple urolithiasis. From these results, this test was considered to be useful in the discrimination between absorptive and renal hypercalciuria.
对55例上尿路结石患者进行了口服钙负荷试验，以发现吸收性或肾性高钙尿症。该患者组的尿钙排泄平均水平显著高于10例上尿路无异常的对照组患者。13例患者出现特发性高钙尿症，定义为男性每天超过250毫克，女性每天超过200毫克；4例吸收性高钙尿症患者，6例肾性高钙尿症患者，3例病因不明的高钙尿症患者。6例肾性高钙尿症患者中有5例有复发性和/或多发性尿路结石。根据这些结果，该试验被认为有助于区分吸收性和肾性高钙尿症。
