Abstract

In the past, kidneys after long-term dialysis represented a terminal state of renal failure, for which the care provided remained primarily atrophy assessment. Later, however, it was suggested that the development of acquired cystic disease of the kidney (ACDK) after prolonged dialysis was associated with renal carcinoma, drawing attention to the importance of the diagnosis of ACDK. Furthermore, in recent years, a rise in the age of incident patients has been observed concurrently with longer periods of dialysis, highlighting that the diagnosis of renal carcinoma is increasingly important. For this reason, ultrasonic examination of the kidneys in patients on maintenance dialysis is conducted as a quasi-requisite test in many dialysis centers today. Meanwhile, changes in the breakdown of underlying diseases among incident patients due to decreases in those originally suffering from chronic glomerulonephritis and increases in those with diabetic nephropathy-derived renal failure in combination with other factors, including modifications occurring after treatments provided prior to dialysis, have caused changes in the kidneys leading them to appear in varied forms after dialysis initiation. Based on the above observations, it is important to fully understand changes over time in kidneys on long-term dialysis, their relations with the underlying pathology, differences between congenital and acquired cystic kidneys, differences between cystic hemorrhage and renal tumors, as well as the contrast-enhanced echo techniques for diagnosis of renal carcinoma, before performing ultrasonic diagnosis in patients on prolonged dialysis treatment.
