1. A method of evaluating an integrity of a patient's uterus, the method comprising:
positioning an expandable structure in a uterine cavity of a patient, the expandable structure comprising a portion of an energy application system for delivering ablation energy to uterine tissue;
expanding the expandable structure within the uterine cavity;
introducing a fluid from a first fluid source into the uterine cavity exterior of the expandable structure;
introducing a fluid from a second fluid source into the expandable structure;
monitoring a flow rate of the fluid introduced into the uterine cavity exterior of the expandable structure; and
monitoring a flow rate of the fluid introduced into the expandable structure;
determining whether the uterine cavity is perforated or non-perforated, wherein the uterine cavity is determined as perforated where the flow rate of the fluid introduced into the expandable structure impinges the flow rate of the fluid introduced into the uterine cavity exterior of the expandable structure.
