An alternative tool for intraoperative assessment of renal vasculature after revascularization of a transplanted kidney.

Intraoperative assessment of flow in the renal artery and vein after reconstruction is a crucial matter in kidney transplantation. Conventional Doppler ultrasound detects blood flow only in a limited area. The authors report a newly developed device that noninvasively visualizes the condition of perfusion of an entire allograft at one time from any angle and also clearly detects the state of anastomosis of the renal vessels. This near-infrared camera system provides the opportunity for the intraoperative assessment of the vasculature of renal allografts.
