title: The role of ultrasonics in the evaluation of renal masses.
abstract: Analysis of our experience with echography in the evaluation of renal masses reveals an error rate of 31 per cent. Presently, this technique may be useful in directing the evaluation of a renal mass to either arteriography, if a tumor is suspected, or needle aspiration and renal cystogram, if a cyst is suspected. However, echography should not replace more definitive studies.
