尿路性器結核の最近の動向 1.日本の尿路結核の死亡率と奈良県における罹患率について

Abstract

Observation was made on yearly changes of number of death and crude death rates from urogenital tuberculosis in Japan based on the vital statistics. On the other hand, statistical studies were performed on newly registered cases of urogenital tuberculosis in Nara prefecture from 1964 to 1970. Following results were obtained. (1) Number of death and crude death rates from urogenital tuberculosis decreased slowly in Japan every years. In 1966 and in 1968, crude death rates from urogenital tuberculosis showed the highest death rates among extra-pulmonary tuberculosis in each year. Furthermore, number of death from urinary tuberculosis occupied 96.5% to 99.7% of death cases from urogenital tuberculosis during the period from 1950 to 1968. These results suggest that there 'He still many incurable cases and severe cases of urinary tuberculosis in Japan. (2) Number of death from urogenital tuberculosis by 5-years age groups in Japan showed most frequent occurrence in the 25~29 age group in 1950 being 279 cases, in the 40~44 age group in 1968 being 36 cases. However, the highest death rate showed in the 25~29 age group in 1950, in the 70~74 age group in 1968. Comparing number of death from urinary tuberculosis by age group from 1950 to in 1968, total number of under 29 years of age group occupies 45.3% in 1950, 13.4% in 1968. On the other hand, total number of over 60 years of age group increased in percentage from 5.3% in 1950 to 19.8% in 1968, which was statistically significant difference (p<0.001). (3) As to sex distribution of death cases from urinary tuberculosis from 1950 to 1968, the male to female ratio was found to be 1.2 with male predominance. (4) Yearly change of morbidity of urogenital tuberculosis in Nara prefecture from 1964 to 1970 showed slight decrease, however, morbidity of urinary tuberculosis showed constant rates. (5) As to sex distribution of newly registered cases of urinary tuberculosis during the period, the male to female ratio was found to be 1.4 with marked male predominance. Age distribution showed the highest incidence in the 4th decade, followed by in the second and the third decade, with the total cases of these three decades of age group occupying 65.5%. (6) The number of newly registered cases of genital tuberculosis in Nara prefecture during the period was 126 cases of male and 21 cases of female. Age distribution of 126 cases showed the highest incidence in the third decade, followed by the second decade, with the total cases of these two decades of age group occupying 50.0%; and total cases of over 40 years of age group occupied 39.4%.
