Oral purine loading: a diagnostic procedure in stone forming patients. 95 stone formers (83 patients with calcium oxalate and calcium phosphate, 12 patients with uric acid stones) and 10 healthy volunteers were given 2 g guanosine as an oral purine load. Calcium oxalate and caldium phosphate stone formers showed two different patterns of uric acid excretion after oral purine loading, correlating with different incidence of recurrent stone formation. Patients with uric acid lithiasis showed initially lower values of urate excretion, after oral purine load no difference of uric acid excretion compared to normal controls was seen.
结石形成患者的一种诊断方法。对95例结石形成者（83例草酸钙和磷酸钙结石患者，12例尿酸结石患者）和10名健康志愿者给予2克鸟苷作为口服嘌呤负荷。草酸钙和磷酸钙结石形成者在口服嘌呤负荷后显示出两种不同的尿酸排泄模式，这与复发性结石形成的不同发生率相关。尿酸结石患者最初尿酸排泄值较低，口服嘌呤负荷后与正常对照组相比尿酸排泄无差异。
