INTRODUCTION
Bladder tumors are common and the only way to prove it is cystoscopy which is invasive and expensive. Finding noninvasive, well-accepted, and cost-effective method for early detection of bladder cancer is necessary. The aim of this study was to evaluate the role of ultrasonography in the diagnosis and evaluation of bladder tumors.
METHODS
This study was conducted on 75 patients with indications for cystoscopy. After recording demographic data, ultrasound, and cystoscopy was performed for all patients. Sensitivity and specificity of sonography in the diagnosis of bladder tumors were measured.
RESULTS
The most common form of bladder in ultrasound was papillary tumors (86%) and the lowest was related to cystic mass (4%). The sensitivity, specificity, positive predictive value, and negative predictive value of sonography for the diagnosis of bladder tumors were 93.24%, 100%, 100%, and 16.66%, respectively.
CONCLUSION
The results of our study showed that ultrasonography has high sensitivity and specificity in the diagnosis of bladder cancer and since that ultrasound is a noninvasive, well-accepted, and cost-effective diagnostic technique, ultrasound can be performed in suspected patients in the first stage.
引言
膀胱肿瘤很常见，而证明其存在的唯一方法是膀胱镜检查，该检查具有侵入性且费用高昂。因此，有必要找到一种非侵入性、易于接受且具有成本效益的方法来早期检测膀胱癌。本研究的目的是评估超声检查在膀胱肿瘤诊断和评估中的作用。
方法
本研究对75例有膀胱镜检查指征的患者进行。记录人口统计学数据后，对所有患者进行超声检查和膀胱镜检查。测量超声检查诊断膀胱肿瘤的敏感性和特异性。
结果
超声检查中膀胱肿瘤最常见的类型是乳头状肿瘤（86%），最少见的是囊性肿块（4%）。超声检查诊断膀胱肿瘤的敏感性、特异性、阳性预测值和阴性预测值分别为93.24%、100%、100%和16.66%。
结论
我们的研究结果表明，超声检查在膀胱癌诊断中具有较高的敏感性和特异性，且由于超声是一种非侵入性、易于接受且具有成本效益的诊断技术，因此可在疑似患者中首先进行超声检查。
