The role of ultrasound in diagnosis and evaluation of bladder tumors.

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.
