Advancing stone treatment: the transformative impact of flexible navigable suction ureteral access sheath (fans) for inferior calyx calculi (<2 cm)

A significantly greater stone clearance rate (96.23% vs. 81.03%, p=0.017) and shorter operative time (37.81 ± 6.07 min vs. 46.59 ± 6.36 min, p<0.001) were observed with the F-Group. Basic attributes, including demographics of patients and stone properties, the infundibulo-pelvic angle (IPA), length of hospital stay, and complications, were compared between the groups and found to be approximately the same.ConclusionsFANS significantly improves SFR without increasing postoperative complications or negatively affecting recovery, offering a promising alternative to conventional sheaths in ureterorenolithotripsy procedures for inferior calyx calculi. FANS improves kidney stone surgery outcomes, is feasible and safe for inferior calyx calculi (<2 cm).
