Acquired cystic disease of the kidney: ultrasound as the primary screening procedure.
Patients with end-stage renal disease on long term dialysis may develop de novo renal cystic disease. We used ultrasound as a primary screening procedure for renal cysts in 71 patients. In seven patients (10%) the native kidneys could not be identified. In 35 patients renal cysts were identified indicating a prevalence of acquired renal cystic disease of 49%.
