Bladder cancer can be grouped into non-muscle invasive bladder cancer (NMIBC) and muscle invasive bladder cancers (MIBC), the latter displaying high aggressiveness, a high degree of malignancy, complicated treatment, high propensity to metastasis, and poor prognosis. Currently, the clinical feasibility and accuracy of preoperative detection of muscle invasion in bladder cancer with contrast-enhanced ultrasonography (CEUS) are unclear.~To evaluate the diagnostic accuracy of CEUS for the preoperative staging of bladder cancer, which would benefit the implementation of efficient therapeutic strategies.
