About this study
Official title: 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.
Read the detailed description
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.

The record says: looking for participants now, as of the sponsor's last update on 13 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does the primary outcome measure?
Detection of Muscle Invasion in Bladder Cancer (time frame: within 3 minutes). It is what the study was designed to measure, not a finding.
