1. A discharge device comprising:
- an elongated flexible main body having a lumen which extends in an axial direction and configured to receive a fluid discharge substance to be discharged inside a biological organ, and a communication hole which communicates with the lumen;
a storage unit that includes a storage space which communicates with the lumen through the communication hole and configured to store the discharge substance, and a discharge section on a proximal surface of the storage unit, the discharge section configured to discharge the discharge substance stored in the storage space toward a proximal side of the main body in the axial direction, and wherein the storage unit is configured to expand and contract in response to introduction and discharge of the discharge substance, the storage unit having a substantially cylindrical shape having a predetermined length in an axial direction when being expanded; and
a hub that is provided in a proximal portion of the main body, and wherein the hub is configured to be connected to and separated from a supply device for supplying the discharge substance.

20. A method of treating urolithiasis, the method comprising:
-
forming calculus fragments by fragmenting a removal target urinary calculus; delivering a storage unit of a discharge device to a distal side of a living body from the calculus fragments, the storage unit having a discharge section on a proximal surface of the cylindrical storage unit; expanding and deforming contracting the storage unit by supplying a predetermined amount of the discharge substance to the storage unit, the storage unit having a substantially cylindrical shape having a predetermined length in an axial direction when being expanded; and moving the calculus fragments toward a proximal side of the living body by causing the discharge substance stored in the storage unit to flow out from the storage unit through the discharge section.
