The study aims at evaluating initial results of flexible ureteroscopy in treatment of renal stone. Materials and methods: Prospective study of 40 patients with kidney stones treated by flexible ureterorenoscopy at Viet Tiep Hospital from october 2020 to june 2021. Results: The average age: 55,88 ± 9,47 (range from 35 to 72 years old), 24 males (60%) and 16 females (40%). Hospitalization: Burning with urination 15%, fever 5%. Hydronephrosis on ultrasound includes: normal 30%, grade 1 37,5%, grade 2 30% and grade 3 2,5%. Stone location: lower calyx 75%, lower calyx and associate other position 25%. Mean size stone: 12,77 ± 4,22 mm (6-20 mm). Ureteral access sheath used in 36 cases (90%). Average operative time: 70 ± 13,82 minutes (40 - 100). Success in operation: 85%, failure: 15%.
