Devices to visualize the ureteral course and avoid ureteral injury are required for minimally invasive surgery (MIS). The NIRC™ fluorescent ureteral catheter (FUC) is a versatile ureteral visualization device currently available in Japan that can be used in combination with a variety of laparoscopic and robotic systems.
