Abstract
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 stinting 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 ease of insertion, and fewer adverse effects.
