INTRODUCTION AND HYPOTHESIS
A dipstick test is recommended to screen for urinary tract infection in patients with overactive bladder (OAB). It was the aim of this study to test if a dipstick test is sufficient to identify patients with urinary tract infection attending a urological private practice because of OAB.
METHODS
All patients who attended the practice because of OAB symptoms were routinely catheterized; a urine specimen was tested with dipstick, the spun sediment was examined microscopically, and the specimen was sent for microbiological examination.
RESULTS
Two thousand two hundred fifty-two patients were examined. Of 1,754 patients with negative dipstick screening, 353 patients (20.1%) had growth of ≥10(3) colony forming units. The dipstick test had a sensitivity of 0.442 and a specificity of 0.865 for the correct identification of urinary tract infection.
CONCLUSIONS
Dipstick screening is not sufficient to identify patients with urinary tract infection and symptoms of OAB.
引言与假设
推荐使用试纸法检测来筛查膀胱过度活动症（OAB）患者是否存在尿路感染。本研究旨在检验试纸法检测对于识别因OAB就诊于泌尿外科私人诊所的尿路感染患者是否足够。
方法
所有因OAB症状就诊的患者均常规进行导尿；用试纸检测尿液标本，对离心后的沉渣进行显微镜检查，并将标本送去做微生物学检查。
结果
共检查了2252例患者。在1754例试纸筛查结果为阴性的患者中，353例（20.1%）有≥10³菌落形成单位的细菌生长。试纸法检测正确识别尿路感染的灵敏度为0.442，特异度为0.865。
结论
试纸筛查不足以识别同时患有尿路感染和OAB症状的患者。
