Abstract
A cystometry system to measure the pressure-volume relationship in the bladder of a patient from a source of fluid comprising, a catheter having an elongated shaft defining an infusion lumen communicating with an infusion opening adjacent a distal end of the shaft, and a pressure lumen communicating with a pressure opening adjacent the distal end of the shaft. The system has a device for supplying a selected volume of fluid from the source to the bladder through the infusion lumen of the catheter, and a device for measuring the bladder pressure through the catheter pressure lumen.
