How to prevent ureteral iatrogenic injuries ?
Preventive Measures Identification and reidentification It is not enough to identify the ureter in one location . convert fibrosis , identify the ureter in an unaffected area. high level of suspicion regarding this injury. The use of prophylactic ureteric stents.
The best strategy is to avoid iatrogenic ureteral injuries The 2 nd best is the intraoperative diagnosis and immediate management Damage control in life threatening situation TAKE HOME MESSAGES
In the OR Insert PCN and ureteral catheter whenever possible Antegrade and retrograde contrast studies are important Endoscopy Exposure TAKE HOME MESSAGES: IN the OR
After surgery Communicate with other Rapidly investigate any surgical problem TAKE HOME MESSAGES: After surgery
