血尿に関する臨床統計

Abstract

1983年1月から1984年9月までに順天堂大学泌尿器科外来を受診した血尿患者に関し検討した.血尿陽性であったものは2, 545例中1, 214例で, 対象群の47.7%を占めた.原因疾患としては尿路感染症, 尿路結石, 尿路悪性腫瘍などが多かった.持続的に認められた血尿では腎炎およびIgA腎症などの内科的疾患が多く, 間歇的血尿では結石, 前立腺肥大症などの泌尿器科的疾患が多かった.悪性腫瘍による血尿はその出現様式, 程度ともに多彩であったが, ことに60歳以上の高齢者の血尿では悪性腫瘍, そのなかでも膀胱癌が多かった.悪性腫瘍による血尿はほとんどが肉眼的血尿であった

The records of 2, 545 outpatients who visited our clinic from January, 1983 to September, 1984, were reviewed retrospectively. Gross hematuria was recognized during the clinical course in 341 patients, and microscopic hematuria, in 873 patients. The patients who experienced hematuria included 701 males and 513 females. The most common causes of hematuria were UTIs (53.0%), urinary tract calculi (15.6%), and malignant tumors (7.1%). Patients with malignancies tended to develop gross hematuria rather than microscopic hematuria; moreover gross hematuria caused by a malignancy was seen more commonly in the elderly population. In renal parenchymal diseases (e.g. glomerulonephritis and IgA nephropathy), continuous hematuria (93.7%) was the rule, although in calculous diseases (55.9%) and prostate hypertrophy (73.9%), intermittent hematuria was more frequent. Hematuria caused by G-U malignancy could not be specified as either microscopic or gross or as either continuous or intermittent. In conclusion, hematuria is a sign of malignancy in 7.1% of all outpatients with hematuria during the clinical course; therefore, a complete examination is indicated for any kind of hematuria.
