Radiation exposure in flexible ureteroscopy with a flexible and navigable suction ureteral access sheath: A European Association of Urology-Endourology multicenter study.

ABSTRACT:

Objective

We aimed to study the effect of flexible ureteroscopy (FURS) for renal stones using a flexible and navigable suction ureteral access sheath (FANS) on intraoperative radiation dose and time.

Methods

This was a multicenter study of adults who underwent FURS with FANS. The correlation analysis was done to identify factors affecting radiation dose and time measured by the C-arm fluoroscopy intraoperatively.

Results

We analyzed 110 patients, with a median age of 50 years. Of them, 72% were pre-stented prior to the procedure. The median stone volume was 1503 mm³ and the median operative time was 39 min. The median radiation dose was 7.4 mSv and median radiation time was 0.6 min. Totally, 91% of patients achieved stone-free status (Grade A or B) on the n
