Randomization between ureteroenteric anastomosis with or without ureteral stent placement will occur at time of surgery; the surgeon will know this information at time of surgery and the patient will be aware of the placement of stents following surgery as these are externalized and visible. The primary outcome will be complication rate in 30 days after the surgery. Secondary outcomes of this trial will include: length of stay, procedure duration, emergency room visits, patient reported pain, anastomotic leakage rate, ureteral stricture rate, post-operative nephrostomy tube placement, differences in complication rates between interrupted and running suture technique.
