Impact of Low Dose Fluoroscopy in Ureteroscopy

Summary

One of the most effective strategies to decrease radiation exposure during ureteroscopy is to use low dose. However, the quality of the image obtained is inferior to full dose image. The main concern is to maintain the stone free and complication rate despite the inferior quality of image obtained. Our aim was to evaluate if reducing the dose of fluoroscopy to ¼ instead of full dose would impact in a reduction of total radiation exposure despite a possible increase in fluoroscopy time. Also, if this strategy would impact in operation time, stone free rate and complication rate of unilateral semi-rigid ureteroscopy for ureteral stone treatment due too less than optimal fluoroscopy image. All patients over 18 years old diagnosed with ureteral stone from 5 mm to 20 mm in diameter by CT scan were counseled regarding their treatment options. Patients who failed spontaneous passage or medical treatment or chose endourologic treatment were included in this study. Patients with abnormal urinary anatomy such as horseshoe kidney, pelvic kidney or duplex system were excluded from the study.
