Acquired Cystic Kidney Disease in Patients Undergoing Long-term Hemodialysis Treatment / 대한비뇨기과학회지

ABSTRACT

PURPOSE: The present study was designed to evaluate the incidence and characteristics of acquired cystic kidney disease (ACKD) in patients with end-stage renal disease who were treated by chronic hemodialysis, using renal ultrasonography. MATERIALS AND METHODS: We performed renal ultrasonography as a screening modality in 112 patients treated with long-term hemodialysis due to end-stage renal disease. We classified the patients years from one to six years. RESULTS: In our study, cystic lesions were noted in 41 patients (36.6%) and there was no sexual predilection of ACKD. Also, a prolonged period of hemodialysis increased the incidence of ACKD, especially for those treated more than 49 months. We encountered a case of renal cell cancer, evaluated it with CT, and then treated it by radical nephrectomy. CONCLUSIONS: With these results, renal ultrasonography can be used as a screening modality in patients treated with long-term hemodialysis more than 49 months due to end-stage renal disease. As complications occur, further evaluation will be needed.
