尿路性器結核の疫学的観察 (シンポジウム: 尿路性器結核の昨日・今日・明日 第22回日本泌尿器科中部連合地方会 )

Abstract

Statistical observations were made on death cases from genito-urinary tuberculosis in Japan from 1950 to 1970. On the other hand, statistical studies were performed on newly registered cases with genito-urinary tuberculosis in Nara Prefecture from 1964 to 1971, and on newly diagnosed outpatients and inpatients with genito-urinary tuberculosis in the urological clinic of Nara Medical University from 1963 to 1971. Following results were obtained. (1) During the period 1951 to 1970 number of death cases and crude death rates from genito-urinary tuberculosis decreased slowly in Japan every year. In 1966 and since 1968, crude death rates from genito-urinary tuberculosis showed the highest death rate among extrapulmonary tuberculosis. Furthermore, number of death cases from urinary tuberculosis occupied over 96.5% of death cases from genito-urinary tuberculosis during the period of 20 years. These results suggest that there are still incurable cases and severe cases with urinary tuberculosis. (2) Morbidity of genito-urinary tuberculosis in Nara Prefecture showed slight decrease during the period of 8 years, however morbidity and number of death cases of urinary tuberculosis showed no remarkable change. Yearly change of newly diagnosed outpatients with genito-urinary tuberculosis in the urological clinic of Nara Medical University during the period from 1963 to 1971 showed the same trend as in Nara Prefecture. (3) Age distribution for the highest incidence of death cases from urinary tuberculosis by 5-year age group in Japan was found in the 25-29 age group in 1950, in the 45-49 and in the 50-59 age group in 1970. The highest incidence was found in the fourth decade by newly registered cases with urinary tuberculosis in Nara Prefecture and by newly diagnosed inpatients with urinary tuberculosis in the urological clinic of Nara Medical University. (4) As to sex distribution of death cases from urinary tuberculosis in Japan during the period from 1951 to 1970, the male to female ratio was found to be 1.22 with male predominance. The male to female ratio was 1.3 with male predominance of newly registered cases with urinary tuberculosis in Nara Prefecture and 1.1 with male predominance of the newly diagnosed inpatients with urinary tuberculosis in urological clinic of Nara Medical University. (5) 17.6% of the newly diagnosed inpatients with genito-urinary tuberculosis and 24.7% of the newly diagnosed inpatients with url'nary tuberculosl's h ave a fam'lI y h istory of some tuberculous diseases. (6) 36.6% of the newly diagnosed inpatients with genito-urinary tuberculosis and 42.7% of the newly diagnosed inpatients with urinary tuberculosis had some extra-urogenital tuberculosis previously. (7) Extra-urinary tuberculous complications in the newly diagnosed inpatients with urinary tuberculosis were genital tuberculosis in 21.3%, pulmonary tuberculosis in 14.6%, and spondylitis tuberculosa in 5.6%~ Association of genital tuberculosis in the male patients was found in 38.3%. (8) Classification of pyelograms according to Lattimer was done on 89 cases, and the results were as follow: IV 56(62.9%), III 18(20.6%), II 8(9.0%), I 5(5.6%) and O 2(2.2%).
