The bladder is an abdominal organ that can be easily evaluated with an ultrasound scan, and with adequate bladder filling, most neoplastic and non-neoplastic bladder diseases are usually well-shown and differentiated by means of ultrasound. In bladder cancer, although ultrasound is not a primary imaging modality for staging, it provides baseline information regarding the depth of tumor invasion. A proper bladder evaluation and the use of a new technical device are extremely helpful in improving the sensitivity and specificity of this simple and noninvasive technology.
