Transabdominal ultrasonotomography of prostatic carcinoma.

In a series of 134 patients with histologically verified prostatic carcinoma, ultrasonotomography, using the transvesical technique, yielded positive results in 97.0% of the cases; in 11.9% inaccessible localization made rectal palpation of the tumour impossible. Ultrasonographic examination is an important contribution to determination of the extent of a tumour whose palpation accessibility is limited and which can be demonstrated only indirectly by radiography. It allows more exact indication of the form of treatment and a non-aggressive follow-up of its effect.
