Abstract

Objectives: To describe the clinical and histopathological characteristics and to evaluate the role of imaging modalities in the diagnosis of non–muscle-invasive bladder cancer (NMIBC) at Cho Ray Hospital. Materials and methods: A retrospective study was conducted on patients diagnosed with NMIBC from January 2019 to January 2024. Data on clinical presentation, imaging modalities (ultrasonography, computed tomography (CT), cystoscopy), and histopathology (T stage, histological grade, tumor characteristics) were analyzed. Results: A total of 156 cases were included, male (89.1%), with a mean age of 63.9 years. Gross hematuria was the main presenting symptom 78.8%. All patients underwent ultrasonography, CT, and cystoscopy. The tumor detection rate of ultrasonography was 36.5%, whereas both CT and cystoscopy achieved 100%. Stage Ta predominated 85.9%, and high-grade tumors accounted for 65.4%. Conclusion: In non–muscle-invasive bladder cancer, gross hematuria was the most common symptom 78.8%. Abdominal ultrasonography had a lower tumor detection rate at 36.5% compared with CT 100% and cystoscopy 100%. Most cases were diagnosed at stage Ta 85.9% with a predominance of high-grade histology 65.4%.
