1. A method of monitoring delivery and recovery of a distension fluid to detect loss during treatment of a body or potential space using a controller, said method comprising:
recording a reference volume of distending fluid contained within a supply container;
supplying an inflow of distending fluid into the body or potential space;
recovering an outflow of distending fluid from the body or potential space;
filtering the recovered distending fluid;
re-circulating the recovered fluid to the supply container to provide a replenished volume; and
calculating a fluid deficit with the controller by subtracting the replenished volume from the initial reference volume;
wherein the controller monitors and signals a fluid deficit parameter on an intermittent or continuous basis via a user interface using at least one signal from a group consisting of visual, aural, and tactile.
