Abstract
Objective To study the clinical diagnostic value of contrast-enhanced ultrasound (CEUS) in bladder occupied lesions. Methods 38 cases of conventional-ultrasound-found bladder occupied lesions did color Doppler flow imaging (CDFI) and CEUS checks. By comparing the difference between two types of blood flow imaging technologies in displaying the flow of bladder occupied lesions and observing the perfusion modes of contrast agents to enter lesions, the perfusion characteristics of CEUS were analyzed. Finally, they were contrasted with the surgical pathology results. Results Of all the 38 cases, there were 51 bladder occupied lesions, including 43 bladder malignant tumors, 2 bladder inverted papillomas, and 6 glandular cystitis lesions. The blood flow display rate of bladder occupied lesions was 100% using CEUS. Apparently, it was higher than that of CDFI (62.7%), and the result of these showed a statistically significant difference (P < 0.05). Using CEUS, 46 malignant lesions and 5 glandular cystitis lesions were indicated, and the diagnostic accuracy rate was 86.3%. Conclusion CEUS can improve the blood flow display rate of bladder occupied lesions, and it can also observe the real-time blood flow of these lesions. It can help judge their nature and has a higher clinical value in differentiating the benign from the malignant.
Highlights
Bladder cancer is the most common malignant tumor in the genitourinary system, and its morbidity and mortality rank the first among male genitourinary tumors in China [1]
contrast-enhanced ultrasound (CEUS) involves the application of ultrasound contrast agents (UCAs), microbubbles with a diameter similar to red cells, to obtain enhanced imaging of the parenchymal microvasculature of tissues based on conventional ultrasonography [3]
As color Doppler ultrasound can detect lesions as small as 5 mm, early detection and early treatment can be achieved, which is of great significance for the observation of pelvic lymph node metastasis and lesion invasion in patients with bladder cancer [9]
Summary
Bladder cancer is the most common malignant tumor in the genitourinary system, and its morbidity and mortality rank the first among male genitourinary tumors in China [1]. As it is convenient, nonradioactive, etc., ultrasonography has been widely used in the diagnosis of bladder tumors and has become an important method to differentiate benign bladder masses from malignant ones. We used CEUS to detect the blood flow of the bladder occupied lesions. Compared with CDFI, the perfusion mode and perfusion characteristics under CEUS were concluded so as to explore the clinical value of CEUS in the diagnosis of bladder occupied lesions
