The incidence of urolithiasis associated with a stone colic has been investigated in general practice in a rural, partly industrialized area of Eastern Norway. Two cases per year per 1000 inhabitants were observed. The incidence showed seasonal variation, with a maximum during the winter and autumn months in four consecutive years. As reported by others, there was an excess of male patients (2.7:1) and of persons with sedentary occupations. A peak stone incidence was found in the middle-aged groups (30-60 years). The probably unselected patient group from the incidence registration was compared with a selected material of patients referred for recurrent stone disease. The unselected patients from general practice showed about 1/5 the median number of stone episodes and 1/4 the median duration of the disease.
在挪威东部一个部分工业化的农村地区的普通医疗实践中，对与肾绞痛相关的尿石症发病率进行了调查。每1000名居民中每年观察到2例。发病率呈现季节性变化，在连续四年的冬季和秋季月份达到最高。正如其他人所报告的，男性患者（2.7:1）和从事久坐职业的人较多。在中年组（30 - 60岁）中发现结石发病率最高。将发病率登记中可能未经过筛选的患者组与因复发性结石病转诊的选定患者材料进行了比较。普通医疗实践中未经过筛选的患者结石发作的中位数约为五分之一，疾病持续时间的中位数约为四分之一。
