Abstract:
Ureteral stricture in renal allografts is one of the common postoperative complications in kidney transplant recipients. Due to short ureter in renal allografts, endovascular treatment should be adopted before reconstruction surgery to avoid irreversible injury. Alleviating renal allograft injury, easing obstruction or establishing drainage channel are the key measures to treat ureteral stricture. In endovascular treatment, balloon dilatation and internal incision yield high recurrence rate, and long-term indwelling of self-expanding metallic ureteral stents may be a better option. Compared with traditional stents, metallic stents may maintain urinary tract patency for a long time and mitigate the irritation of lower urinary tract symptoms,with different indications and efficacy. Although all metallic stents may be displaced and occluded, it still plays a positive role in the treatment of ureteral stricture in renal allografts. In this article, the application of self-expanding metallic ureteral stent in ureteral stricture of renal allografts was mainly illustrated, aiming to provide reference for optimizing the treatment of ureteral stricture in renal allografts.
