[Transurethral and transrectal examination of the bladder and prostate by ultrasound (author's transl)].

This article describes a non-invasive technique of intravesical examination used for the purpose of staging a bladder tumour and to assess the state of the prostatic bed during and after electrical transurethral resection. The apparatus visualises the bladder tumour and its infiltration using a type B image produced by rotation of an ultrasonic head. In addition it is easy to estimate the dimensions, size and weight of a benign tumour of the prostate using a transrectal ultrasonic probe.
