1. A method for using a kidney stone removal system, comprising:
positioning the kidney stone removal system within a kidney of a patient having a kidney stone by accessing the kidney via a ureter of the patient, wherein the kidney stone removal system comprises a vacuum lumen through which suction can be applied;
irrigating the kidney via the kidney stone removal system;
fragmenting the kidney stone into a plurality of kidney stone fragments using a laser fiber supported within a distal portion of the vacuum lumen;
removing at least a portion of the plurality of kidney stone fragments through the vacuum lumen using a passive negative pressure to create outflow; and
applying suction through the vacuum lumen to remove an additional portion of the plurality of kidney stone fragments, wherein
the vacuum lumen is in open communication with ambient air during passive negative pressure so as to provide a different vacuum pressure than during the applying suction through the vacuum lumen to remove the additional portion of the plurality of kidney stone fragments.
