title: Characterization of renal stone models with Gray Scale echography. In vitro studies with clinical correlation.
abstract: Solid, matrix, and urate stone models were studied in an idealized laboratory setting by gray scale echography. The stone models could be both identified and characterized by ultrasound. Preliminary studies indicate that ultrasound may be useful in determining the nature of foreign matter in the collecting systems of patients with renal calculous disease.
