Asymptomatic microscopic hematuria is a common finding that demands urologic evaluation. Of the 236 patients over the age of 40, 6.8% were found to have a genitourinary cancer, while 27.5% had other significant urologic disease. However, 52.1% of the patients had unknown etiology of microscopic hematuria and 13.6% had insignificant urologic lesions. Of the 72 patients under the age of 40 a positive diagnosis was made in 16 patients (22.2%). Cystoscopic examination was of diagnostic value in only 1 patient. Therefore, cystoscopy is of little diagnostic value in young patients. Once asymptomatic microscopic hematuria is established and no etiological cause is identified, we follow the patient by urinalysis and cytology every three months and reevaluate the patient in whom urological symptoms develop.
无症状镜下血尿是一种常见的检查结果，需要进行泌尿外科评估。在236名40岁以上的患者中，6.8%被发现患有泌尿生殖系统癌症，而27.5%患有其他重要的泌尿系统疾病。然而，52.1%的患者镜下血尿病因不明，13.6%有不严重的泌尿系统病变。在72名40岁以下的患者中，16名（22.2%）得到了阳性诊断。膀胱镜检查仅对1名患者有诊断价值。因此，膀胱镜检查在年轻患者中的诊断价值不大。一旦确定为无症状镜下血尿且未发现病因，我们每三个月通过尿液分析和细胞学检查对患者进行随访，并对出现泌尿系统症状的患者进行重新评估。
