Abstract:
【Objective】 To evaluate the safety and efficacy of long-term indwelling of Allium ureteral stent in the treatment of ureteral stricture. 【Methods】 The clinical data of patients who underwent endoscopic Allium ureteral stent implantation for ureteral stricture in our hospital during Aug.2020 and Dec.2022 were retrospectively analyzed, and the surgical conditions and adverse events were recorded. The data of serum creatinine, blood urea nitrogen, glomerular filtration rate (GFR) and renal pelvis width under ultrasound were compared before surgery and 1, 3, 6 and 12 months after surgery. 【Results】 A total of 52 patients with ureteral stricture of 1.1 (0.7, 2.0)cm were included. All operations were successful. The operation time was 82.5 (70, 114)min, intraoperative blood loss 20 (10, 20)mL, and postoperative hospitalization stay 1 (1, 2) day. During the follow-up of (13.2±7.8) months, 14 patients had stent displacement, 5 had stone obstruction of stent tubes, 7 had occasional hematuria after movement, 9 had intermittent lumbar and abdominal pain, and 1 had recurrent urinary tract infection. The serum creatinine, blood urea nitrogen and renal pelvis width of 1 month, 3, 6 and 12 months after surgery were significantly decreased, while GFR was significantly increased. 【Conclusion】 Long-term indwelling of Allium ureteral stent is effective in the treatment of ureteral stricture, but the high incidence of stent displacement should arouse attention.
