ABSTRACT
With a little help from my friends John Lennon (1940-1980) and Paul McCartney (1942-)
ULTRASONOGRAPHY has revolutionized the diagnosis of urological disorders. It is the perfect partner to good radiography, since the contrast of ultrasound pictures is often best at times when radiographic contrast is reduced, for example in the presence of fluid. It is particularly useful in demonstrating abnormalities of the internal architecture of soft tissue organs and in the diagnosis and localization of collections of fluid within or around viscera. It is especially helpful in the differentiation of prostatic disorders, especially cysts and abscesses. Ultrasonography allows accurate localization of a lesion so that meaningful and safer (ultrasoundguided) biopsy or fluid samples can be obtained.
