To study computed tomography (CT) imaging characteristics of bladder tumors, to explore the value of CT in tumor diagnosis, and to identify the relevant factors of CT missed diagnosis so that medical staff can be more accurate in the diagnosis of bladder tumors.
To retrospectively analyze the CT manifestations of 153 bladder tumor cases confirmed by paraffin pathology in our hospital and to study the difference between the benign and CT imaging features. CT indicators mainly include the number, location, morphology, calcification, bladder wall smoothness, CT value, degree of enhancement, and invasion of surrounding tissues and organs. Then, we retrospectively analyze 17 cases of CT missed diagnosis of bladder tumors, analyze related factors, and discuss the role of CT in the diagnosis of bladder tumors.
This study has shown that with the help of CT images, the diagnosis rate of bladder tumors has been greatly improved. Of the 153 patients studied, noninvasive urothelial carcinoma accounted for 18.95% of all benign and malignant bladder tumors, invasive urothelial carcinoma accounted for 67.93%, prostatic metastatic carcinoma and inflammatory myofibroblastoma accounted for 8.47%, pheochromocytoma accounted for 1.31%, inverted papilloma accounted for 1.31%, tubular choriocarcinoma accounted for 0.63%, and endocystitis accounted for 1.31%. In addition, the blood supply level, CT index bladder wall smoothness, and CT value are also statistically significant ( < 0.05).
CT is of high value in the diagnosis of bladder tumors, and benign and malignant bladder tumors have CT and CT imaging features. The size of bladder tumors is related to the missed diagnosis rate of CT. The application of CT examination technology can improve the accuracy of diagnosis of bladder tumors.
研究膀胱肿瘤的计算机断层扫描（CT）成像特征，探讨 CT 在肿瘤诊断中的价值，明确 CT 漏诊的相关因素，以便医务人员在诊断膀胱肿瘤时更加准确。
回顾性分析我院经石蜡病理证实的 153 例膀胱肿瘤 CT 表现，并研究良、恶性 CT 影像学特征的差异。CT 指标主要包括数目、位置、形态、钙化、膀胱壁光滑度、CT 值、强化程度及周围组织器官侵犯情况。然后，回顾性分析我院 17 例膀胱肿瘤 CT 漏诊病例，分析相关因素，并探讨 CT 在膀胱肿瘤诊断中的作用。
本研究表明，借助 CT 图像，膀胱肿瘤的诊断率得到了极大提高。在研究的 153 例患者中，非浸润性尿路上皮癌占所有良恶性膀胱肿瘤的 18.95%，浸润性尿路上皮癌占 67.93%，前列腺转移癌和炎性肌纤维母细胞瘤占 8.47%，嗜铬细胞瘤占 1.31%，内翻性乳头状瘤占 1.31%，管状绒毛膜癌占 0.63%，膀胱炎占 1.31%。此外，血供水平、CT 指标膀胱壁光滑度、CT 值比较差异均有统计学意义（ < 0.05）。
CT 对膀胱肿瘤的诊断具有较高价值，良、恶性膀胱肿瘤具有 CT 及 CT 影像学特征。膀胱肿瘤的大小与 CT 漏诊率有关。CT 检查技术的应用可以提高膀胱肿瘤的诊断准确率。
