| Popis: | To the Editor. As the authors indicated, due to the high incidence of renal cell carcinoma among patients with acquired cystic disease of the kidney and the necessity for screening these high risk patients, ultrasonography is the most suitable diagnostic tool as a noninvasive and relatively inexpensive screening method. For the last 12 years, we performed periodic ultrasonographic examination as a screening method in 690 patients on dialysis at our hospital.' However, degenerated echogenic cysts and small renal cell carcinoma hidden in the kidneys with acquired cystic disease are often misleading with falsepositive and false-negative findings. Our experience with 16 cases of renal cell carcinoma' is different from that of the authors and their repetitive view.3 Ultrasonography missed 4 cases (see table). Contrary to their experience with angiography (detection rate 659), we performed angiography in 11 patients (4 with stage T1 and 7 with stage T2 disease) and recognized tumor vessels or tumor stain in every case without any adverse effect. Angiography provides definitive information when ultrasonography and computerized tomography tCT) findings are equivocal. |
