Abstract:
Objective:To explore the preliminary results of using the UreteroPyeloVisClear Catheter (VCC) in the treatment of ureteral stones.Methods:A retrospective analysis was conducted on the clinical data of 18 patients with ureteral stones who underwent treatment with VCC at Beijing Tsinghua Changgung Hospital from November 2023 to March 2024. The cohort consisted of 15 men and 3 women, with a mean age of 53 years (range: 27-75 years). The preoperative CT measurements showed that the mean maximum stone diameter was 9 mm (range: 3-18 mm), and the mean maximum CT value of the stones was 870 HU (range: 260-1 480 HU). The distribution of stones was as follows: 3 cases in the upper ureter, 8 in the middle ureter, and 7 in the lower ureter. Gravity-assisted perfusion was used, and all patients underwent VCC combined with Holmium laser lithotripsy, with flexible ureteroscopy used if necessary. A ureteral stent was routinely placed for 2 weeks postoperatively. Perioperative conditions and complications were analyzed.Results:All 18 patients successfully underwent VCC lithotripsy, with one patient experiencing stone migration during the procedure. The average operation time was 53 minutes (range: 20-100 minutes), and the average lithotripsy time was 25.5 minutes (range: 6–60 minutes). There were no significant changes in serum creatinine or hemoglobin levels on the first postoperative day. The average hospital stay was 2 days (range: 1–3 days). One patient experienced a fever (maximum temperature of 38.5℃), which resolved with antibiotic treatment. The visual analogue scale (VAS) scores on postoperative day 1 were 0 for 15 patients, 2 for 1 patient, 3 for 1 patient, and 4 for 1 patient. No complications of Clavien-Dindo grade Ⅱ or higher were observed. At 1-month follow-up, the stone-free rate (SFR) was 100%(18/18), and no hydronephrosis was observed in the affected kidney.Conclusions:The results of this study indicates that VCC is a safe and effective method for treating ureteral stones, with a low incidence of postoperative complications and a high stone clearance rate.
