無症候性顕微鏡的血尿の臨床的検討

Abstract

1)無症候性顕微鏡的血尿患者の200例に泌尿器科的精査を施行し, 血尿の原因となる疾患が92例に見つかった.2)血尿の原因疾患は遊走腎, 腎のう胞, 慢性膀胱炎の順に多かった.3)治療を要した疾患は28例で, 悪性腫瘍は膀胱腫瘍の2例だけであった.4)血尿の程度と疾患の重症度との間に相関はなかった

A statistical survey was performed on 200 patients with asymptomatic microhematuria who visited our hospital between January 1986 and October 1989. Urinalysis, urinary cytology, urinary culture, IVP, echography and cystoscopy were carried out for the evaluation of the origin and nature of the microhematuria. In 92 patients (46%), urological abnormalities were observed. Among them, urological lesions requiring medical and surgical treatments were found in 28 patients (14%) including two malignant cases of bladder tumor. No urologic lesion could be identified in 108 patients (54%). The degree of hematuria was unrelated to the seriousness of its cause. Thirteen of 28 patients (46%) with diseases that required treatment had under 5 red blood cells per high power field on the microscopic urinalysis. Therefore, complete urologic investigation of all patients with any degree of asymptomatic microhematuria is recommended.
