1. A method for determining an intraperitoneal volume during peritoneal dialysis, comprising the steps of:

  • passing a peritoneal solution from a peritoneal cavity in a first circuit adjacent a first side of a semipermeable membrane;

    passing a dialyzing fluid in a second circuit adjacent a second side of the semipermeable membrane;

    measuring the concentration of an endogenous substance in the peritoneal solution, wherein the endogenous substance passes through a peritoneum into the peritoneal solution in the peritoneal cavity; and

    determining the intraperitoneal volume from the variation in the concentration over time.
