Despite the widespread practice of endopyelotomy for the management of ureteropelvic junction obstruction, the optimal conditions for ureteral healing after endoincision remain largely untested. Current recommendations for the use of large-caliber graduated endopyelotomy stents and a 6-week duration of stenting are being challenged by recent reports of successful outcomes with the use of standard, small-caliber ureteral stents and early stent removal. Moreover, improvements in stent design have led to the development of endopyelotomy stents with improved biocompatibility, enhanced case of insertion, and fewer adverse effects.
尽管肾盂内切开术在输尿管肾盂连接部梗阻的治疗中应用广泛，但肾盂内切开术后输尿管愈合的最佳条件仍未得到充分验证。目前关于使用大口径刻度肾盂内切开术支架及6周支架置入时间的建议，正受到近期一些报告的挑战，这些报告表明使用标准小口径输尿管支架并早期取出支架也取得了成功结果。此外，支架设计的改进导致了肾盂内切开术支架的发展，其生物相容性得到改善，置入更容易，且不良反应更少。
