Evaluation of the Preoperative Detection of Muscle Invasion in Bladder Cancer with Contrast-enhanced Ultrasonography: a Prospective Study
To evaluate the diagnostic accuracy of CEUS for the preoperative staging of bladder cancer, which would benefit the implementation of efficient therapeutic strategies.
Inclusion: (a) eligible patients should be 18-year-old or older; (b) patients should have a histologically or cytologically confirmed diagnosis of primary bladder cancer; (c) patients should not have had any surgery, chemotherapy, immunotherapy, or any therapy before CEUS diagnosis.
Exclusion: (b) participants with previous pelvic surgery, who had undergone therapy, any bladder surgery, or had received chemotherapy, radiotherapy or immunotherapy; (c) participants diagnosed with tumor recurrence or metastasis; (d) participants who were allergic to ultrasound contrast agents or could not tolerate CEUS examination, for instance, with recent myocardial infarction, angina pectoris, cardiac insufficiency, severe cardiac arrhythmia, a right/left cardiac shunt, severe pulmonary hypertension, uncontrolled systemic hypertension, acute respiratory distress syndrome, or chronic obstructive pulmonary disease; (a) participants with confirmed to have no carcinoma of the bladder.
