Abstract: 本邦に於ける尿路結石症の発生頻度を知る為に泌尿器科外来患老数に対する尿路結石症が患老数の比率を求めて各地域別に比較した.全般的には北方に少く南方に多く, 地方別に記せば四国, 中国, 九州, 近畿, 中部, 関東, 東北, 北海道の順である.瀬戸内海沿岸地方及び九州の一部に於て特に多い事は注目すべきである.結石の部位的分布状態については, 全症例を集計すれば尿管結石, 膀胱結石, 腎結石, 尿道結石, 前立腺結石の順であり, 昭和29年現在に於ける状態は尿管結石45.12%, 腎結石27.31%, 膀胱結石20.6.70/, , 尿道結石4.66e/., 前立腺結石2.17%である.結石の部位的分布状態も地域的に多少の差があり, 上部尿路結石症の比率が高いのは関東及び九州地方であり, 低いのは東北及び近畿地方であつて, 下部尿路結石症に関してはその逆である・過去20年間の尿路結石患者数は昭和14年を頂点とし, 以後漸次減少し昭和20年を底として, 以後急激に増加し昭和29年には戦前の数倍に達している.下部尿路結石症はその増減が極めて僅かであるのに対し, 上部尿路結石症は昭和12年より昭和19年まで及び昭和2?年以降に増加して2っの結石波を示している.上部尿路結石症の内でも尿管結石症の変動が著しい.戦後に於ける結石波は特に大きくその原因探求は今後に残された問題である.年令及び性別関係は従来の統計と大差はない.男女の比は5.6:1である.年令的には20才代が最も多く29.45%, 次いで30才代であり10才未満及び80才以上は極めて少い.患者の職業別を調査したがそれによる明確な差異は見出し得なかつた.ただ農村人に於ては都会人に比較して上部尿路結石症が少く, 下部尿路結石症が多い傾向を認めた.尿路結石症の発生に就ては未だ不明の点が多く, 疫学的にも多くの問題が残されている.本論文は向後に於ける同方面の研究の一助となれば幸である.
We sent cards of inquiry to urological clinics of the principal hospitals all over the country, and receiving 130 answers from them, we made a statistical investigation on "Urolithiasis in Japan". To find the frequency of urolithiasis, we obtained the percentages of urolithiasis in whole numbers of ambulatory patients of urological clinics, and campared the results regionally. Generally speaking, it was less in the northern regions and more in the southern regions, especially much more found along the coastal regions of the Seto Inland Sea and a part of the Kyushu region. As the total figure throughout the country, the patients of urolithiasis were 3.84 % of the ambulatory patients. The location of calculus was investigated in these twenty years, and in 1954 it was classified as follows: Ureteral calculus 45.12 % Renal calculus 27.31 % Vesical calculus 20.67 % Urethral calculus 4.66% Prostatic calculus 2.17% Surveying the numbers of urolithiasis in the past twenty years, we found that there was one peak in 1939 and then it gradually decreased until 1945. Thereafter there was rapid increase with a sharp curve in 1954 approximately two and a half as much as the number in 1939. The increase and decrease of the urolithiasis in the lower urinary tract was very little, but there were two so-called stone waves in the urolithiasis in the upper urinary tract, one in pre-war days and the other in post-war. The postwar stone wave is especially remarkable. We further more made some investigations about the relation between the disease and sex, age, and occupation.
