Summary
Fluorescent ureteral catheters enhance safety in robotic colorectal cancer surgery by improving dissection visualization. This case study demonstrates their effectiveness in preventing ureteral injury during complex sigmoidectomy.
Area of Science:
- Urology
- Surgical Oncology
- Medical Imaging
Background:
- Robotic surgery for colorectal cancer, including locally advanced cases, is increasing.
- Adhesions and fibrosis in advanced cancers heighten risks of misidentification and injury, especially ureteral damage, during robotic dissection due to lack of tactile feedback.
- Near-infrared light-activated fluorescent ureteral catheters offer potential for intraoperative navigation.
