During the 48-year period from January, 1938 to December, 1985, upper urinary tract stones obtained from 794 patients were analyzed by infrared spectroscopy in our Department. Their clinical manifestations were studied, mainly in relation to stone composition. The ratio of males to females was 3.0 to 1. In recent years, the incidence of females tended to increase. In the age distribution, twenties were most frequent followed by thirties together with fourties before 1965, but after 1966, the thirties were most frequent, and fourties and fifties increased. The composition of 794 stones was as follows. The most frequent type was calcium oxalate combined with calcium phosphate (43.1%), followed by calcium oxalate (39.8%) and calcium phosphate (9.6%). Magnesium ammonium phosphate stones were found in 1.6% and uric acid stones in 2.9%. Calcium oxalate stones, uric acid stones and oxalate-containing stones were found more frequently in males than in females. On the other hand, magnesium ammonium phosphate stones, calcium phosphate stones and phosphate-containing stones were found less frequently in males than in females. There was a high occurrence of calcium phosphate stones and uric acid stones in patients older than 60 years old. The occurrence of calcium oxalate stones and uric acid stones increased and that of phosphate-containing stones decreased after 1966. Most of the recurrent stones revealed the same or similar composition as the initial stones.
在1938年1月至1985年12月的48年期间，我们科室对794例患者的上尿路结石进行了红外光谱分析。研究了其临床表现，主要涉及结石成分。男女比例为3.0比1。近年来，女性发病率呈上升趋势。在年龄分布方面，1965年以前，二十多岁的患者最为常见，其次是三十多岁和四十多岁的患者，但1966年以后，三十多岁的患者最为常见，四十多岁和五十多岁的患者有所增加。794颗结石的成分如下。最常见的类型是草酸钙与磷酸钙混合（43.1%），其次是草酸钙（39.8%）和磷酸钙（9.6%）。磷酸镁铵结石占1.6%，尿酸结石占2.9%。草酸钙结石、尿酸结石和含草酸结石在男性中的发现频率高于女性。另一方面，磷酸镁铵结石、磷酸钙结石和含磷结石在男性中的发现频率低于女性。60岁以上患者中磷酸钙结石和尿酸结石的发生率较高。1966年以后，草酸钙结石和尿酸结石的发生率增加，含磷结石的发生率下降。大多数复发结石的成分与初始结石相同或相似。
