Introduction: chronic kidney disease (CKD) is frequently associated with acquired renal cystic disease (ARCD). The latter condition is usually clinically asymptomatic, but it may complicate with renal carcinoma. Objective: identify the frequency of presentation of ARCD and the possible relationship of renal length and the number and size of cysts, to characteristics of patients on hemodialysis. Methods: an analytical cross-sectional study was conducted of all the patients on hemodialysis at the Institute of Nephrology in June 2012. Patients with cystic disease as the cause of CKD, nephrectomized patients and those with a poor echographic window were not included. Renal echography was performed with high resolution Toshiba Nemio XG equipment and a 3.5 MHz convex transducer. Data was processed with the statistical software SPSS version 15.0. The Wilcoxon-Mann-Whitney and Kruskal-Wallis tests were used for identification of the possible relationships between variables. The Pearson linear correlation coefficient (r) was also used. Results: 38.4 % of the patients had ARCD. An association was found between the number of cysts and the time on hemodialysis, the doses of erythropoietin used, and hemoglobin values (p< 0.05 in the three cases). The relationship between time on hemodialysis and number of cysts was direct and moderate (r= 0.60). Conclusions: the frequency of ARCD was high among patients on hemodialysis. The number of cysts increased with treatment time. Patients with a greater number of cysts have higher hemoglobin values and require smaller doses of erythropoietin
