Abstract

Abstract: Objective To investigate the efficacy and safety of flexible ureteroscopy （FURS） in the treatment of upper urinary tract stones. Methods The clinical data of 60 patients with upper urinary tract stones from April 2022 to December 2023 were retrospectively analyzed. All patients were treated with FURS. Among them, there were 13 cases of renal pelvis stones, 11 cases of upper calyceal stones, 14 cases of middle calyceal stones, 10 cases of lower calyceal stones, 12 cases of upper ureter stones; 39 cases of stone diameter ≤20 mm, 21 cases of 20-40 mm stones. Results All the 60 patients successfully completed the operation, and the operation time was （44.29±11.71） min. No complications occurred during the operation. After operation, 11 cases of fever （18.33%）, 14 cases of hematuria （23.33%）, 1 case of urinary sepsis （1.67%）, 5 cases of lumbago （8.33%） occurred. All patients were followed up, and 53 patients reached the stone removal standard, among which 39 patients had no stone residue and 14 patients had stone residue ≤4 mm, and the total stone removal rate was 88.33%; 7 cases did not meet the standard of stone removal, and the unremoved rate was 11.67%, among which 4 cases received extracorporeal shock wave lithotripsy, 3 cases again underwent FURS.The first-stage removal rates of renal pelvis, upper calyceal, middle calyceal, lower calyceal, and upper ureter stones were 100.00%（13/13）, 81.82%（9/11）, 100.00%（14/14）, 60.00%（6/10）, and 91.67%（11/12）, respectively. The first-stage removal rates of stones with diameter ≤20 mm and 20-40 mm were 92.31% （36/39） and 80.95% （17/21）, respectively. There were no statistically significant differences in the first-stage removal rates of stones in different parts and with different diameters （P>0.05）. The patients were followed up for 8 to 19 months, and no stone recurrence or renal atrophy occurred. Conclusion FURS is safe and reliable in the treatment of upper urinary tract stones with high first-stage stone removal rate.
