三重大学泌尿器科における尿路結石症の臨床的観察

Abstract

1) 1974年よりの10年間の尿路結石症患者は1, 433例で, 同症は外来患者の10.1%を占めた.2)上部尿路結石症は男子の40歳代にピークがみられ, 好発年齢の高齢化が進んでいると考えられた.3)中結石(6×10 mm以下)の場合でも, 6ヵ月までは十分に自然排石が期待できると考えられた.4)男子の73.2%は蓚酸Ca含有結石で, 女子の81.6%はリン酸塩含有結石であった.5)入院結石患者において, 過Ca尿症は34.0%で, 尿中細菌培養陽性率は33.0%であった

The urinary tract calculus patients seen at our Department between January, 1974 and December, 1983 were reviewed to determine the trend of urolithiasis. The urinary tract calculus patients accounted for 10.1% of all the outpatients. Recurrent calculus diseases were seen in 16.9% of male patients and in 12.1% of female patients. The frequency of recurrence was very high in the patients in their forties. Upper urinary tract calculi were seen most frequently in the patients in their forties. We could expect spontaneous passage of stone for at least 6 months in the case of a middle-sized stone (less than 6 X 10 mm). The percentage of calcium oxalate-containing stone was 73.2% in male patients and the percentage of phosphate-containing stones was 81.6% in female patients. Hypercalciuric patients were seen in 34.0% of the calculus inpatients. Urinary bacterial culture revealed positive in 33.0% of the calculus inpatients.
