Seventeen dialysis patients with renal cell carcinoma were examined preoperatively by ultrasonography, computerized tomography (CT) and angiography. Ultrasonography, CT and angiography correctly predicted the diagnosis of renal cell carcinoma in 17 (100%) and 12 (71%) of 17, and 11 (69%) of 16 patients, respectively. All renal tumors of more than 3.0 cm in diameter were detected by the three diagnostic procedures. However, ultrasonography, CT and angiography detected renal tumors of less than 3.0 cm in 12 (100%) and 7 (58%) of 12 patients and 6 (55%) of 11 patients, respectively. Seven renal cell carcinomas were associated with acquired cystic disease of the kidney (ACDK). All renal tumors were found by ultrasonography. However, CT predicted the correct diagnosis in 3 (43%) of 7 patients with ACDK and in 9 (90%) of 10 patients without ACDK, and angiography was correct in 3 (50%) of 6 patients with ACDK and 8 (80%) of 10 patients without ACDK. Our results indicate that ultrasonography is an effective procedure to detect renal cell carcinomas in dialysis patients.
