In reviewing our experience in the field of bladder ultrasonography, we conclude that this method is seldom used because its value has not been disseminated widely. Such a method is especially valuable in the investigation of infiltrative bladder tumors and the calculation of bladder volume. We herein report the results obtained in 100 patients whose bladder content has been calculated with the formula 12.56 times radius times height. We also outline the advantages of ultrasound over catheterization.
Tridimensional transrectal prostatic ultrasound is an imaging test applicable in the clinical practice which offers quality images and may provide great benefits for the diagnosis and local staging of prostate cancer, by means of the analysis of the front view.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
