Abstract
We describe 3 cases of hemodialysis patients with spontaneous rupture of acquired cystic kidney disease (ACDK). All patients suddenly complained of colicky flank pain. Computed tomography (CT) demonstrated bulky hematoma with swollen ACDK. Blood examination showed progressing anemia and hyperkalemia. We transfused a total of 800ml packed cells to the first case, 1000ml to the second case and 1200ml to the third case. Simultaneously hemodialysis was performed using nafamostat mesilate to improve hyperkalemia. After these treatment, anemia and hyperkalemia were corrected, and the patients' symptom disappeared. A few months later CT showed that the hematoma had been absorbed.
