The infundibulum of the caliceal diverticulum was incised with a calculase II holmium laser (230 microoptical fiber, 1.0 J-10 Hz), and the calculi were pulverized with low energy and high frequency (0.8 J-25 Hz) (Figure 3).

II holmium laser (230 mum optical fiber) (Figure 5), and the calculi were fragmented, with high energy and low frequency (1.2 J-6 Hz) into gravel less than 2 mm, and the rest of fragments were removed with a small caliber basket (Figure 6). In order to ensure that the kidney drains urine well after F-URS, a ureteral stent was left in place and then removed the following morning.
