1. A method of performing an integrity test for a uterus of a patient, the method comprising:

inserting a uterine ablation device into the uterus of the patient;

delivering a fluid into the uterus from a reservoir that is part of or connected to the uterine ablation device;

measuring a level of an air-fluid interface within the reservoir with one or more sensors of the reservoir;

controlling a fluid supply system to deliver fluid into the reservoir when the level of the air-fluid interface within the reservoir reaches a lower threshold during the integrity test; and

determining that there is a leak in the uterus when a flow rate of the fluid supply system does not remain below a flow rate threshold for a predetermined amount of time during the integrity test.
