The sentinel stent? A systematic review of the role of prophylactic ureteric stenting prior to colorectal resections.

Placement of prophylactic ureteric stents has a low complication rate. There is insufficient evidence to conclude that stents decrease ureteric injury or increase intraoperative detection of IUIs. Apparently higher rates of IUI in stented patients likely reflect use in higher risk resections. A prospective registry with harmonised data collection points and stratification of intraoperative risk is needed.
