Sonographic Findings of Early Prostatic Cancer:With Clinical Correlation

최근 전립선암의 증가로 인해 전립선암의 조기 발견이 점차 중요시되고 있으며 저자들은 지난 1년6개월간 경직장 초음파를 시행후 조직학적으로 진단된 전립선암 22례중 비교적근치적 수술이 가능한 stage A와 B의 조기전립선암 7례를 대상으로 후향적분석을 하였으며 수지직장검사와 혈청 PSA검사, 경직장 전립선 초음파는 같이 시행할 경우 상호 보완적인 점에서 조기전립선암의 발견율이 증가될 것으로 사료된다.We retropectively analyzed 7 cases of transrectal ultrasonography(TRUS) of patients with early prostatic cancer(stage A & B) and correlated with clinical findings such as digital rectal examination(DRE), serum PSA, and pathologic Gleason grade. TRUS detected prostatic cancer in 5 of 7, PSA was elevated above normal range in 6 of 7, and hard nodules were palpated in 6 to 7. One case of stage A adenocarcinoma of prostate was not detected sonographically due to inhomogeneous echogenecity. One case of stage B adenocarcinoma of prostate was not detected due to its isoechogenecity. Five cases stage B adenocarcinoma were located at the peripheral zone and showed hypoechoic lesions in TRUS. We conclude that TRUS is useful in detection of early prostatic cancer when combined with serum PSA and DRE.We retropectively analyzed 7 cases of transrectal ultrasonography(TRUS) of patients with early prostatic cancer(stage A & B) and correlated with clinical findings such as digital rectal examination(DRE), serum PSA, and pathologic Gleason grade.

CT Differentiation of Renal Cell Carcinoma and Renal Pelvis Urothelial Tumor

It may be difficult to differentiate renal cell carcinoma involving collecting system from renal pelvis urothelial tumor invading into renal parenchyma. The purpose of this study was to find out CT differential points of two diseases. Renal cell carcinoma was characterized by no hydronephrosis(80%), normal CT renal function (100%) and outward bulging mass(100%). However, renal pelvis urothelial tumor showed hydronephrosis(70%), abnormal CT renal function(60%) and preserved reniform shape(100%). In conclusion, renal contour changes and CT renal function are reliable criteria in differentiating two diseases.It may be difficult to differentiate renal cell carcinoma involving collecting system from renal pelvis urothelial tumor invading into renal parenchyma.
