Ultrasonic diagnosis in and about the kidney.

EARLY in the investigation of ultrasonic diagnosis of retroperitoneal organs it became apparent that kidney parenchyma is highly transonic. As a result of the surrounding connective tissue, as well as the strong echo-producing characteristics of the structures in the renal hilum and pelvis, the kidneys yield a characteristic echographic appearance. Thus, the kidney has been one of the first organs examined by echographic scanning. With recent improvements in ultrasonic diagnostic technology, it has become even more accessible to evaluation by this method. The intravenous urogram is, of course, satisfactory for most diagnostic needs requiring renal imaging. Occasionally, however, one encounters a patient who has poor renal function or in whom for other reasons intravenous urography does not yield complete results. In such cases—and for some other applications—the new diagnostic tool of reflected ultrasound scanning has become useful, is now accepted as a clinical examination beyond the experimental stage, and yields
