[Sonography of the efferent urinary tract. Suprapubic and intravesical methods]

The ability of sonographic methods to demonstrate the urinary passages and their abnormalities were studied systematically. The ureters can only be demonstrated if they are dilated. Sonography of the bladder can be used as a screening method for tumours, diverticula and stones. Intravesical sonography is useful for staging of bladder tumours. The value of these methods is discussed.
