High-resolution microultrasound imaging for bladder cancer: the birth of a new diagnostic tool?

Historically bladder cancer (BC) has been diagnosed with transurethral resection (TUR) (1), which is the gold standard, and imaging was not considered very useful to assess the invasiveness of BC. Computed tomography urography is generally used for BC staging but has a poor spatial resolution and provides only few details about tumor invasion into the muscolaris propria.
