慢性肾脏病流行病学调查中确定持续血尿的筛查报告

目的基于慢性肾脏病（CKD）流行病学调查资料，通过对初诊为血尿患者进行复查，了解持续血尿的患病率，为慢性肾脏病血尿筛查提供参考。方法对北京市进行的慢性肾脏病流行病学调查中的沉渣镜检确定为血尿的患者进行尿试纸条、二次尿沉渣镜检和相差显微镜检查，并进行问卷调查。结合北京市调查结果，推算持续血尿患病率。结果234例接受了复查（回访率为50．1％），经过二次尿沉渣镜检确定为持续血尿的患者仅55例，占23．5％，其中肾小球源性血尿47例，北京市持续血尿患病率为0．8％。结论在流行病学闶查中建议行两次尿沉渣镜检，以确定持续性血尿的患者作为加强随访的对象。

The screening for persistent hematuria in survey of chronic kidney disease

Objective To investigate the prevalence of persistent hematuria in the survey of chronic kidney disease by repeating the urine test in hematuria patients. Methods 467 patients who were identified as hematuria by microscopy in Beijing chronic kidney disease（CKD） survey study were asked to repeat urine tests five months later. Every subject received questionnaire. In the repeated test, patients who got a uric positive result of dipstick were asked to take urine examination with the microscopy and the phase contrast microscopy to confirm and recognize the origin of the hematuira. Based on the result of Beijing chronic kidney disease（CKD） survey study, the prevalence of the persistent hematuria was evaluated and the underlying diseases of persistent hematuria were diagnosed with the help of the phase contrast microscopy, ultrasound and cystoscope. Results There were 234 patients accepted the repeated test（ the response rate is 50.1% ） , of which 55 patients were identified with persistent hematuria. The rate of persistent hematuria among the subjects who were diagnosed as hematuria in the first microscopic examination was 23.5%. 47 cases of hematuria were originated from glomerular disease and the other 8 patients were not. The prevalence of the persistent hematuria was 0.8%. Conclusion Our results suggested that repeated examination of urine sediment was necessary in hematuria participants in CKD survey study.
