显微镜血尿作为泌尿道肿瘤的筛查程序

Microscopic hematuria as a screening program for urinary tract malignancies

目的建立显微镜血尿方法与尿红细胞（RBC）计数的诊断界线，证实可以列入筛查泌尿道肿瘤的程序。方法调查3批军人和一批地方体检尿分析尿红细胞，研究总结泌尿系统肿瘤574例住院病人尿红细胞（RBC）计数。结果尿试条潜血特异性为94．6％。尿沉渣定量板诊断界线为RBC≤8μl，此相当于尿沉渣镜检RBC0-3／hp。在10例显微镜血尿〉50岁者中查出1例膀胱癌。临床106例膀胱癌病人尿红细胞为237±524／μl；门诊231例体检者尿红细胞为0．3±2．0／μl。结论尿红细胞计数RBC≥9／μl，可作为膀胱上皮细胞癌初筛标志物，显微镜血尿继以尿道造影术、尿道膀胱镜、细胞学证实。

Objective Although an urinalysis is a widely application, it has not yet been shown if microscopic hematuria is an appropriate and useful screening marker for urologic malignancies. In order to create a diagnosis criteria of urine erythrocyte counting and to confirm the screening marker.Methods It is invented that urinalysis and urine erythrocyte counting of 3 group soldier 1 groupt locality. The incidence of Microscopic hematuria was studied in 574 patients with urinary tract malignancies. Results There is 94.6% specificity of urine strip hemoquant. Urine erythroeyte counting RBC≤8/μl as diagnosis criteria, Such correspondent microscopic examination RBC 0 - 3/hp. One case bladder cancer is found and for diagnosing in 10 asymptomatic 〉 50 year adults with microhematuria. Urine erythrocyte counting is 237 ±524/μl in 106 case bladder cancer. Urine erythrocyte counting is 0.3 ± 2.0/μl in 231 health examination.Conclusion It is an appropriate screening marker for urothelial carcinomas, particularly in elderly men, that urine erythrocyte counting RBC ≥ 9/μl as Microhematuria. It is identified that detection of tract imaging, cystourethroscopy,and cytologic examination.
