東邦大学皮膚泌尿器科に於ける最近5年間の結石症について

Abstract

During the past five years, 342 cases of urolithiasis were found among the 3, 821 cases of urological patients who visited the Toho University medical school clinic. Clinical statistical analysis of these 342 cases gave the following results. Thirty-nine cases of them showed double location of stones in the urinary tracts. (1) The occurrence of urolithiasis during the past five years was 8.95 p e r cent of the whole cases. (2) They consisted of 78 cases (20.5%) of renal, 234 (61.4%) of ureteral, 35 (9.2%) of vesical, 13 (3.4%) of urethral and 21 (5.5%) of prostatic calculi. The number of the patients with calculus in the up p er urinary tracts was much more than that of the patients with calculus in lower urinary tracts. So-called "Stone wave" was revealed. (3) As to sex, the condition w as found to occur for more frequently in males (280 cases : 81, 87%) than in females (62 cases : 18, 13%). The ratio was 4.5 to 1. (4) Age distribution of the cases showed 152 occurred in the third decade and 90 in the fourth decade. (5) As to seasonal variation, the results were reported previously. (6) As to occupations of the patients, the results of a nalysis shound higher incidence among office workers. (7) The r ecurrence was 20 cases (5.25%). (8) As the initial symptoms and th e chief complaints pain and haematuria were observed most frequently.(9) Treatment of the upper urinary tract calculi was surgical operation in about a half of cases while the other half received conservative therapy. For cases of vesical and urethral calculi, endosc o pic treatment was commonly used, and for cases of prostatic calculus, the treatment was conservative in all of them. It should be noted that cases of spontaneous discharge or chemical dissolution of stones have been increasing.
