Sonograms in 205 patients undergoing dialysis were obtained to evaluate renal features according to duration of treatment. Both length and parenchymal thickness had gradually decreased in kidneys treated for < 3 yr. After the 3rd yr of treatment, an apparent increase in the incidence of cysts was seen. Forty-three cases of acquired cystic disease, including 1 case with renal cell carcinoma, were detected. All kidneys had increased cortical echogenicity, with prominence first occurring after 7 yr of dialysis. In patients undergoing dialysis for < 3 yr, those with diabetic nephropathy showed fewer changes from normal appearances than patients undergoing dialysis for treatment of glomerulonephritis.
