尿淀粉酶/尿肌酐比值在急性胰腺炎诊断中的意义

Significancl of the Ratio of Urine Amylase to Urine Creatinine Assay in the Diagnosis of Acute Pancreatitis

目的:探讨尿淀粉酶/尿肌酐比值在急性胰腺炎诊断中的意义。方法:对52例急性胰腺炎患者、50例非胰腺炎急腹症患者和50例健康对照人员进行血淀粉酶(Samy)、尿淀粉酶(Uamy)、尿肌酐(Ucr)测定。结果:急性胰腺炎尿液Uamy/Ucr敏感性为92.31%,特异性为92.00%,均高于临床常用的诊断指标Samy和Uamy。结论:尿淀粉酶/尿肌酐比值是较好的早期诊断急性胰腺炎的指标。

Objective：To explore the apply of the ratio of urine amylase to urine creatinine in the diagnosis of acute pancreatitis. Methods：Serum amylase, urine amylase and urine creatinine in 52 patients with acute pancreatitis,50 patients with nonpancreatitis acute abdomen, and 50 healthy people were detected and compared. Results：The sensitivity and specificity of the ratio of urinary amylase to urinary creatinine assay were 92.31% and 92.00% （cut off value： 75%）, which were also higher than those of the two traditional assays for the diagnosis of acute pancreatitis. Conlusion： The ratio of urine amylase to urine creatinine assay is better for the diagnosis of acute pancreatitis in the early stage.
