Acquired cystic disease of the kidney (ACDK) has been frequently noted among adult patients treated with long-term dialysis. This association has not been well studied in the pediatric population and there have been only a few related papers published so far. We evaluated the incidence of ACDK in 15 pediatric patients treated in our hospital. Fifteen patients (9 males and 6 females) with chronic renal failure being treated with hemodialysis were studied with ultrasonography and/or CT scan. The mean age when dialysis was initiated was 13 years and 10 months. Patients had been dialyzed for a mean of 7 years.
Four patients (26.6%) had no cysts, two (13.3%) had solitary cysts and nine patients (60%) had bilateral multiple cysts (ACDK). Duration of dialysis therapy was greater in patients with ACDK (105.1±38.8 months) compared to those with solitary cysts (65.5±14.5 mo) or no cysts (46.5±21.2 mo). All patients who had undergone dialysis for more than seven years had ACDK. A sex difference was noted with there being a higher incidence among males (males: 7/9, females: 2/6). ACDK frequently occurs in children treated with long-term dialysis. Neoplasm formation in one of the complications of ACDK, and routine screening of pediatric patients who undergo dialysis may be necessary.
