[The echotomographic diagnosis of renal expansive processes (author's transl)]

The authors carried out a study of renal echotomography as a diagnostic technique for renal expansive processes. The reliability of the results obtained, the simple technique, its absolute harmlessness and the low cost are tending to give echotomography an increasingly important place in the differential diagnosis of renal masses. This limits, without eliminating, the indications for arteriography and exploratory surgery. It should in no way be considered to be in competition with radiography, but rather as an excellent complementary technique. By the use of apparatuses giving moving images, our group obtained 96.4 per cent of success in liquid masses and 90.3 per cent of success in solid masses.
