A peritoneal function testing method of using a ratio MTAC.sub.un/MTAC.sub.c calculated using MTAC.sub.un and MTAC.sub.c as an index for a peritoneal function test. MTAC.sub.un is an overall mass transfer-area coefficient for urea nitrogen and MTAC.sub.c is an overall mass transfer-area coefficient for creatinine. Use of the MTAC.sub.un/MTAC.sub.c ratio enables examination of the future peritoneal function of a patient (a mechanism of deterioration in peritoneal function). MTAC.sub.un and MTAC.sub.c are obtained using a Pyle-Popovich model. The peritoneal function testing method further calculates a permeability coefficient for cell pores (L.sub.PS.sub.C) and an overall permeability coefficient (L.sub.PS) from a Three-Pore Theory model to obtain a ratio L.sub.PS.sub.C/L.sub.PS calculated using the L.sub.PS.sub.C and the L.sub.PS, and further uses the L.sub.PS.sub.C/L.sub.PS ratio and the MTAC.sub.un/MTAC.sub.c ratio as indexes for the peritoneal function test.

Method for testing peritoneum function and a peritoneal dialysis planning apparatus

A peritoneal function testing method uses a ratio of MTAC.sub.un/MTAC.sub.c, calculated using MTAC.sub.un and MTAC.sub.c, as an index for a peritoneal function test, wherein MTAC.sub.un is an overall mass transfer-area coefficient for urea nitrogen and MTAC.sub.un is an overall mass transfer-area coefficient for creatinine. The use of MTAC.sub.un/MTAC.sub.c enables examination of the future peritoneal function of a patient (a mechanism of deterioration in peritoneal function). To be specific, MTAC.sub.un and MTAC.sub.c can be obtained by computing a Pyle-Popovich model. In addition, the peritoneal function testing method further calculates a permeability coefficient for cell pores (L.sub.pS.sub.C) and an overall permeability coefficient (L.sub.PS) from a Three-Pore Theory model while obtaining a ratio of L.sub.PS.sub.C/L.sub.PS calculated using the L.sub.PS.sub.C and the L.sub.PS. The L.sub.PS.sub.C/L.sub.PS ratio and the MTAC.sub.un/MTAC.sub.c ratio can be used as indexes for the peritoneal function test.

The present invention is a peritoneal function testing method characterized by using a ratio MTAC.sub.un/MTAC.sub.c calculated using MTAC.sub.un and MTAC.sub.c as an index for a peritoneal function test, where MTAC.sub.un is an overall mass transfer-area coefficient for urea nitrogen and MTAC.sub.c is an overall mass transfer-area coefficient for creatinine. The use of MTAC.sub.un/.sub.c of the present invention in this way enables examination of the future peritoneal function of a patient (a mechanism of deterioration in peritoneal function). To be specific, MTAC.sub.un and MTAC.sub.c can be obtained by computing Pyle-Popovich model. In addition, the peritoneal function testing method may further calculate a permeability coefficient for cell pores (L.sub.PS.sub.C) and an overall permeability coefficient (L.sub.PS) from Three-Pore Theory model while obtaining a ratio L.sub.PS.sub.C/L.sub.PS calculated using the L.sub.PS.sub.C and the L.sub.PS, and may use the L.sub.PS.sub.C/L.sub.PS ratio and the MTAC.sub.un/MTAC.sub.c ratio as indexes for the peritoneal function test.
