1. A medical fluid management system, comprising:
a fluid reservoir having an initial volume;
a filter system having a fluid retention volume;
a first fluid line configured to carry a fluid from the fluid reservoir through the first fluid line to a body cavity, the first fluid line having a fluid retention volume;
a second fluid line configured to carry the fluid from the body cavity through the second fluid line to the filter system, the second fluid line having a fluid retention volume; and
a third fluid line configured to carry the fluid from the filter system through the third fluid line back to the fluid reservoir, the third fluid line having a fluid retention volume;
wherein the initial volume of the fluid reservoir minus a sum of the fluid retention volumes of the filter system and the first, second and third fluid lines equals 2.5 liters or less.
 
19. A medical fluid management system, comprising:
a fluid reservoir having an initial volume;
a filter system having a fluid retention volume, the filter system including a tissue capturing filter and a molecular filter;
a check valve fluidly coupled between the tissue capturing filter and the molecular filter;
a first fluid line configured to carry a fluid from the fluid reservoir through the first fluid line to a body cavity, the first fluid line having a fluid retention volume; and
a second fluid line configured to carry the fluid from the body cavity through the second fluid line to the filter system, the second fluid line having a fluid retention volume; and
a third fluid line configured to carry the fluid from the filter system through the third fluid line back to the fluid reservoir, the third fluid line having a fluid retention volume;
wherein the tissue capturing filter is configured to catch resected tissue;
wherein the molecular filter is configured to filter out red blood cells.
