Invasive cancer urinary Tests can have little diagnostic value, Kaiser Permanente study warns

Hematuria, or blood in the urine can trigger a battery of urinary tests for cancer are invasive and unnecessarily expose patients to radiation, but the procedures contribute little to the diagnosis, according to a study conducted by Department of research & evaluation of the Kaiser Permanente Southern California published in May the issue of the Journal of Urology...

VCUG is a common x-ray that shows the bladder and lower urinary tract. Using motion x-ray called fluoroscopy, the radiologist is able to view and assess the function of the bladder and urinary tract, watching as the bladder is filled and emptied with a water-based contrast solution.

Digital radiography in urologic imaging: radiation dose reduction on urethrocystography.

Digital luminescent radiography (DLR) is a new form of digital radiographic technology which can be used as an alternative to conventional radiologic systems; it replaces conventional screen-film systems by photostimulable phosphorus. Due to the linear dynamic range of photostimulable phosphorus, x-ray examinations can be performed with significantly lower radiation exposure. In this study radiation dose was reduced by about 90% using DLR for urethrocystography.
