title: Controlled continuous flow (CCF) resectoscope. Report of 200 cases.
abstract: Controlled continuous flow (CCF) is a new balanced pumping system which has been designed for the resectoscope. The system is controlled by an intravesical pressure sensor. Upper limits of pressure are set, and the input flow is shut off electronically if it is attained. Flow rates of up to 1,000 ml/minute can be achieved for maximum clarity of vision. Two hundred cases have been performed with the CCF resectoscope. Various parameters were measured and are presented. The results indicate that TURP can be performed safely and more efficiently with the CCF resectoscope.
