title: Presymptomatic diagnosis of adult onset polycystic kidney disease by ultrasonography.
abstract: Results of an ongoing prospective study of progeny of patients with adult-onset polycystic kidney disease using grey-scale ultrasound and high-dose nephrotomography are reported. Six asymptomatic subjects out of 17 at risk for polycystic kidney disease were found by ultrasonography to have multiple renal cysts; this included two unrelated children aged 18 months and 6 y who had normal high-dose nephrotomography. We suggest that ultrasonography may be the method of choice for presymptomatic detection of polycystic kidney disease. Serial studies of at-risk individuals by sonography will be useful in determining the earliest age of detection, the latest age of ultrasonography presentation, and in following the natural history of polycystic kidney disease.
