METHODS: Proposed by EULIS ureteroscopy committee, prospective data gathered from 15 countries. Ethical approval for annonymised IRB registry obtained by Asian Institute of Nephrology and Urology, Hyderabad ( #AINU 12/2022). Inclusion criteria:Adult with solitary renal stone and normal anatomy undergoing RIRS using FANS. Data recorded for baseline and operative characteristics .A non- contrast CT scan within 24 hours to document as a proof of concept study, reported SFR, intra and immediate postoperative complications and exit strategy.UVA, MVA performed for 100% SFR, expressed as ORs and 95% CI. RESULTS: 142 cases, median stone volume of 1165 mm3. Preferentially11/13 Ffr (44.4%) FANS with a disposable scope (77.5%) under general anaesthesia (80.3%), used in 86.6% cases.TFL most commonly used .Only 15.5% cases needed stone fragments repositioning with basket.Mean laser, total ureteroscopy time (the time scope and sheath were handled together in pcs) and overall operative times were was 16.5, 35.5 and 48.5 min respectively. In 84.5% cases, DJ stent and in 9.2% and 6.3% patients an overnight ureteric catheter or no drainage respectively. In the latter, a change from their routine exit strategy was reported by the surgeon in 12.7% cases 46.5% cases reported visual complete clearance confirmed by 24Hr NCCT. Complication were low, CD 1 and II, fever (7%), ureteric injury grade I (n=4), grade II (n=1) needed stenting. No sepsis. Overall SFR was 96.5%. Reintervention planned In 4 off 5 patients with fragments >4 mm. CONCLUSIONS: For the first time utilising a CT scan 24-hrs post RIRS with FANS, as proof of concept we document how FANS achieved a high immediate single stage SFR with minimal iatrogenic and infective complications by safely navigating the PCS and effectively using suction to extract fragments and dust in a global multicentre prospective study. This minimised use of baskets and unnecessary stenting.
