Studies on 65 cases of incidental renal cell carcinoma : Significance of ultrasonography in diagnosis / 대한비뇨기과학회지

ABSTRACT

The medical records of two hundred and sixteen(216) cases of renal cell carcinoma during the period. January 1980 to June 1991, were investigated and analyzed with particular attentions on incidental discovery, stage and prognosis ; and value of ultrasonographic examination for early detection. Of 216 cases, 65 cases(30.1%) were diagnosed incidentally ; 10.4% in 1980-1985. 21% in 1986-1989, 65% in 1990 and 68.4% in 1991. Of 65 cases of incidental discovery, 44 cases(67.8%) were initially detected by ultrasonography. Stages were lower in incidental cases(64.6 %. stage I and II) than in sysmptomatic cases(39.7 %, stages I and II). Ultrasonography is very valuable in early detection and screening of renal cell carcinoma but its cost-effectiveness should be furtherevaluated.
