title: [Mechanical pressure regulator for transurethral surgery of the bladder].
abstract: A new device is presented, rendering to constant pressure conditions during transurethral operations without need of intravesical pressure determination. Using a double sheath resectoscope the device is solely connected to the irrigation system. By backflow, intravesical pressure changes are transmitted to a membrane within the device. Irrigation is then controlled accordingly by a connected valve. In order to adapt bladder configuration to a situation ideal for performing resections, intravesical pressure can be set manually by regulating the tension of the membrane with a spring.
