Seven hundred patients with 735 urinary calculi were studied for the compositions of calculi by infrared analysis and for stone recurrence. Of these 700 cases, 422 cases were possible to follow up, and 250 cases have had no further stone; 138 cases experience recurring stones, and 34 cases had multiple stones. The length of follow-up period was 1-19 years averaging 8 years, 8 months. 41.2% of patients with calcium oxalate-calcium phosphate calculi had stones recurrently, and although there was some variation of recurrence rates for patients with various proportions of oxalate to phosphate in the calculi, it was impossible to predict the tendency of recurrence by these proportions. The stone recurrence was noted in 38.6% of patients with magnesium ammonium phosphate calculi, in 38.9% with mixed magnesium ammonium phosphate-calcium oxalate calculi, in 55.6% with uric acid calculi, and in 50% with cystine calculi.
对700例患有735枚尿路结石的患者进行了研究，通过红外分析确定结石成分，并观察结石复发情况。在这700例病例中，422例得以随访，其中250例未再出现结石；138例经历了结石复发，34例有多发结石。随访期为1至19年，平均8年8个月。草酸钙 - 磷酸钙结石患者中41.2%出现结石复发，尽管结石中草酸与磷酸盐比例不同的患者复发率存在一定差异，但无法通过这些比例预测复发倾向。磷酸镁铵结石患者中38.6%出现结石复发，磷酸镁铵 - 草酸钙混合结石患者中38.9%出现复发，尿酸结石患者中55.6%出现复发，胱氨酸结石患者中50%出现复发。
