Editing Management of Upper Urinary Tract Obstruction (section)

=== Management ===
* '''See Figure in Campbell's'''
*'''Antegrade endourologic management of ureteroenteric or ureterocolic strictures is preferred''', unlike the management of ureteral strictures
* '''Strictures > 2cm or on the left are less likely to succeed with endourologic management'''
** Endourologic success rate for
*** Strictures > 1cm is 6% vs. 50% strictures < 1 cm
*** Left sided-stricture 19% vs. 41% on the right
**** No difference was noted in sidedness with open repair
* '''Although long-term patency of minimally invasive procedures for ureteroenteric strictures is in the range of 50%, such approaches are still used as the initial intervention''', reserving operative management for those patients in whom endourologic intervention fails and for patients with strictures > 1 cm
* '''When considering endoscopic incision of a left ureteroenteric stricture, the risk of hemorrhage is a consideration because the sigmoid mesentery can be in close proximity. This, taken with the lower success rates of all endoscopic approaches on the left side, supports serious consideration for primary repair when treating left ureteroenteric anastomotic strictures'''
