a drain structurally configured for connection to a bladder of a patient;
a fluid conduit structurally configured for connection with a vascular system of the patient and for fluid communication with the drain, the fluid conduit comprising:
a first portion having a first porosity;
a second portion disposed immediately adjacent to the first portion, the second portion having a second porosity that is greater than the first porosity, wherein the second porosity is configured to permit a predetermined filtrate transport through the second portion and into the drain; and
a third portion disposed immediately adjacent to the second portion, the third portion having a third porosity that is less than the second porosity, wherein each of the first portion, the second portion, and the third portion are integrally formed as a single, continuous piece defining the fluid conduit; and
a pump configured to control a flow of filtrate from the fluid conduit through the drain.
