Yang, Weon Seok; Park, Jong Duk

Abstract

Ultrasonography were performed on 52 patients with 64 cases of urologic diseases, and its significance was discussed. The results were as follows: 1. Overall diagnostic accuracy of ultrasonography was 90.6% and diagnostic error was 9.4%. 2. It is not helpful to use ultrasonography as a primary screening procedure or to use it alone, but it is recommended to use ultrasonography as a supplementary measure after excretory urography. 3. Many needless renal angiographys and explorations can be avoided by performing ultrasonography prior to renal angiographys and explorations to get more accurate information. 4. Ultrasonography is known to be atraumatic, noninvasive and not harmful to human body, and it may be used safely in children and pregnant women. 5. Ultrasonography can be performed regardless of renal function and is particularly helpful in differentiating between cystic and solid masses. 6. Ultrasonography was particularly helpful in the diagnosis of non-visualization of kidney in I.V.P.
