Abstract

The recent advent of percutaneous removal of renal calculi — including extraction, dissolution, and ultrasonic or electromechanical destruction of calculi — makes it important to determine the chemical composition of a patient’s calculus prior to deciding upon the best method of therapy. While blood chemistry, examination of the urine sediment, and review of the patient’s clinical history are helpful in this regard, the true nature of a calculus often remains in doubt. The experiment detailed in this report represents an initial, ex vivo evaluation of computed tomography (CT) as a method of improving the categorization of calculi prior to deciding upon a treatment plan. Our results indicate that CT may prove to be a useful adjunct to traditional clinical and laboratory methods for discriminating among types of renal calculi.
