Voided urine specimens from 82 cases of histologically verified urothelial neoplasia (transitional cell carcinoma grades I, II, III, and carcinoma in situ [CIS] ) were evaluated for the presence of gross and microhematuria (MH). Microhematuria was assessed macroscopically with the reagent-strip blood test and evaluated microscopically with enumeration of erythrocytes using a standardized semiquantitative Papanicolaou-stained urine sediment examination. The authors' retrospective study indicated that gross hematuria rarely was present in urothelial neoplasia, however, occult blood (greater than 5 RBC/HPF) was present in four out of five cases when one sample was examined. In some cases there was an overlap between the number of erythrocytes excreted by control population and those with urothelial neoplasms. Urine sediment examination was more sensitive than reagent-strip testing for MH in patients with urothelial neoplasia.
对82例经组织学证实的尿路上皮肿瘤（移行细胞癌I级、II级、III级和原位癌[CIS]）患者的晨尿标本进行肉眼血尿和镜下血尿（MH）检测。镜下血尿通过试剂条潜血试验进行宏观评估，并使用标准化半定量巴氏染色尿沉渣检查对红细胞进行计数，从而进行微观评估。作者的回顾性研究表明，肉眼血尿在尿路上皮肿瘤中很少出现，然而，当检查一份样本时，五分之四的病例存在潜血（大于5个红细胞/高倍视野）。在某些情况下，对照组人群和尿路上皮肿瘤患者排出的红细胞数量存在重叠。对于尿路上皮肿瘤患者，尿沉渣检查对镜下血尿的检测比试剂条检测更敏感。
