Abstract

Objective: To evaluate the indications and outcomes of renal stone management using digital flexible ureteroscopy (fURS) at Bach Mai Hospital. Subjects and Methods: A cross-sectional descriptive study was conducted on 123 patients who underwent digital fURS between May 2023 and July 2025. Parameters included indications, operative time, stone-free rate immediately after surgery and at 1 month, ureteral injury according to the Traxer classification, hospital stay, and JJ stent duration. Results: Digital fURS was mainly indicated for patients with lower pole stones (56.9%) and renal pelvic stones (52.0%), with a mean stone size of 12.9 ± 4.5 mm. Most patients presented with lumbar pain (98.4%) and had no prior surgical intervention (87.0%). The mean operative time was 65.04 ± 22.57 minutes, including a mean lithotripsy time of 49.68 ± 21.61 minutes. The stone-free rate (≤ 4 mm) was 75.6% immediately after surgery and increased to 87.8% at 1 month (p < 0.01). No ureteral injuries of grade ≥2 were recorded; the majority were grade 1 abrasions (69.9%). The mean hospital stay was 4.89 ± 4.51 days, with most patients discharged within 3–4 days (70.7%). The mean JJ stent duration was 14.04 ± 8.32 days, mostly 8–14 days (65.9%). Conclusion: Digital fURS is a safe and effective treatment for renal stones, with a high stone-free rate, minimal complications, and rapid recovery. It is suitable for broader implementation in tertiary urological centers in Vietnam.
