[Cost-effectiveness of ultrasound in a urology department].

Ultrasonography has demonstrated to be a precise test with high sensitivity and specificity. The urologist is the most capable professional to obtain the maximum effectiveness of this technique, so that the availability of ultrasound machines in urology departments rationalizes and limits the demand of ultrasound tests, diminishes significantly the indication of radiological tests and the number of cystoscopies, being an indispensable element in high-resolution office consultations. We report the statistics of the use of ultrasound in our department, with the disappearance of the demand of ultrasound tests from the urology outpatient clinic to the radiology department. The use rate is high, reflecting the functional criteria for use of the ultrasound equipment. In the economic analysis we found there is an almost complete absence of controlled clinical trials comparing the cost effectiveness of imaging tests in urology. There are not cost studies comparing ultrasounds performed by the urologist with those performed by radiologists.
