Abstract: Flexible ureteroscopy lithotripsy (FURS) is the most common treatment for patients with upper urinary tract calculi (diameter, <2 cm). The purpose of this prospective study was to assess the efficacy of FURS combined with metallic ureteral stents (MUS) for the treatment of upper urinary tract calculi. A total of 38 patients with upper urinary tract calculi were recruited in the present study, to compare the efficacy between FURS and FURS combined with MUS (FURS-MUS). The results demonstrated that FURS-MUS shortened operative time compared with FURS (35.2±1.2 vs. 57.4±1.7 min, respectively; P<0.01). Data also indicated that the clearance rate in FURS-MUS and FURS was decreased from 94.5 and 87.8%, respectively (P<0.05). FURS-MUS treatment decreased the duration of postoperative hospital stay compared with FURS (4.5±0.5 vs. 7.5±1.5 days, respectively; P<0.05). These data demonstrated that FURS-MUS significantly increased postoperative inflammation score compared with FURS (6.2±0.8 vs. 4.2±1.0, respectively; P<0.05). The complication rate and blood loss exhibited no significant difference between FURS-MUS and FURS (complication rate, 6.5% vs. 5.9%, respectively; blood loss, 4.2% vs. 4.6%, respectively). FURS-MUS significantly decreased inflammatory cytokines and risk of sepsis, and improved readmission rate, stone recurrence and progression-free survival compared with patients treated with FURS. In conclusion, these data suggested that FURS-MUS may be an efficient, minimally invasive and reproducible operation for patients with upper urinary tract calculi.
