A retrospective study of the results of dipstick testing and microscopical examination of urine from 10 050 men undergoing health screening showed a prevalence of occult haematuria of 2.5%. Those patients with occult haematuria who were resident in the United Kingdom and registered with a general practitioner were identified and a questionnaire sent to their general practitioners asking what further investigations had been performed. The response rate was 92% (152/165 inquiries). Fifty nine general practitioners (39%) had not instigated any investigations. Among the 76 patients who underwent some further investigations abnormalities were found in 21 (28%); and among those fully investigated by examination of midstream urine, intravenous urography, and cystoscopy abnormalities were found in 12(50%). These included bladder neoplasms (two; one in a patient aged 37), epithelial dysplasia (one), staghorn calculi (one), and chronic reflux nephropathy (one). It is proposed that occult haematuria should be fully investigated regardless of the age of the patient.
一项针对10050名接受健康筛查男性的尿液试纸检测和显微镜检查结果的回顾性研究显示，隐匿性血尿的患病率为2.5%。确定了那些居住在英国且在全科医生处注册的隐匿性血尿患者，并向他们的全科医生发送了一份问卷，询问进行了哪些进一步检查。回复率为92%（165份询问中有152份回复）。59名全科医生（39%）未进行任何检查。在76名接受了一些进一步检查的患者中，21名（28%）发现了异常；在那些通过中段尿检查、静脉肾盂造影和膀胱镜检查进行全面检查的患者中，12名（50%）发现了异常。这些异常包括膀胱肿瘤（2例；1例发生在37岁患者）、上皮发育异常（1例）、鹿角形结石（1例）和慢性反流性肾病（1例）。建议无论患者年龄大小，都应对隐匿性血尿进行全面检查。
