Objective To evaluate the diagnostic accuracy of computed tomography (CT) for pelvic lymph node metastasis in muscle-invasive bladder urothelial carcinoma (MIBUC). Methods The present study retrospectively assessed the clinical and imaging characteristics of 40 MIBUC patients who underwent radical cystectomy and pelvic lymphadenectomy. The relationship between CT imaging characteristics and pathological examination for pelvic lymph node metastasis was assessed in MIBUC patients. Results (1) Compared to pathological diagnosis, CT imaging examination for pelvic lymph node metastasis had an accuracy of 90%, a sensitivity of 75%, and a specificity of 93.8%. (2) The pelvic lymph node metastasis rate increased along with more advanced tumor stage (T1, 0; T2, 9.1%; T3, 45.5%; T4, 100%). Conclusions (1) CT imaging characteristics are of great importance for evaluating pelvic lymph node metastasis in MIBUC patients. (2) The probability of metastatic pelvic lymph nodes significantly increases with more advanced T stages in MIBUC patients (P<0.05).
