Predicting Grade and Stage at Cystoscopy in Newly Presenting Bladder Cancers-a Prospective Double-Blind Clinical Study

For clinical purposes, in newly presenting patients with bladder cancer, urologists appear to reliably predict lower grade and muscle-invasive disease, confirming widely held belief. This allows for appropriate and efficient use of surgical expertise, available technology, and selection of participants for clinical trials on the basis of prehistology risk categories.
