Our study attempted to answer the following questions: What percentage of patients at routine hospital admission have notable urine sediment abnormalities? Is the urine specific gravity related to the yield of sediment abnormalities? Is there an increased yield of sediment abnormalities when the test is specifically requested by the physician? Of 442 patients admitted to the hospital, microscopic sediment abnormalities were present in 28%. In one half of these, the only abnormality was the presence of WBCs. There was no relationship between the yield of microscopic abnormalities and urine specific gravity. When the examination was specifically requested by the physician, our work load dropped by 75%. However, surprisingly, the yield of abnormalities did not increase. Therefore, we recommend that microscopic sediment examination be performed on every patient admitted to the hospital.
常规入院的患者中，有明显尿液沉渣异常的患者比例是多少？尿比重与沉渣异常的检出率是否相关？当医生特别要求进行该项检查时，沉渣异常的检出率是否会增加？在442名入院患者中，28%存在显微镜下的沉渣异常。其中一半患者，唯一的异常是存在白细胞。显微镜下异常的检出率与尿比重之间没有关系。当医生特别要求进行该项检查时，我们的工作量下降了75%。然而，令人惊讶的是，异常的检出率并未增加。因此，我们建议对每一位入院患者都进行显微镜下的沉渣检查。
