Summary

Kidney stones are very common, and can inflict a significant degree of pain and renal damage. Some stones become obstructed in the ureter, the tube that drains the kidney. In order to remove these stones, an Urologist and their team use fluoroscopic guidance to do so, this involves continuous X-ray. Flouroscopy delivers a significant dose of radiation to the patient, as well as the health care team, which has been shown to have serious health consequences. Previous studies have shown that in certain populations, like pregnant women, stones can be managed using ultrasound guidance. The investigators propose that mid and distal ureteral stones could be managed using ultrasound guidance in conjunction with conventional stone removal techniques (ureteroscopy, lithotripsy, and ureteral stent placement), in lieu of fluoroscopy, thereby minimizing radiation to healthcare staff and patients.

The investigators hypothesize that distal ureteral stones can be identified and efficiently fragmented and removed under ultrasound guidance in a safe and effective manner without the use of radiation.
