[Acquired cystic kidney disease among hemodialysis patients: echographic and clinical study].

Thirty-six of 56 (64%) patients on chronic hemodialysis for 1 to 194 months were found to have ACKD (at least 3 cysts per kidney) by means of ultrasonographic evaluation. The number, size and extent of cysts were positively and significantly correlated with the months on hemodialysis. There was also a significant positive correlation between grade of ACKD and Hb. Moreover there was a significant positive association of abdominal pain; none had suffered from hemorrhage or neoplasm.
