Use of SPY Elite Fluorescence Imaging in Creation of a Continent Urinary Diversion

Abstract

The use of SPY Elite Fluorescence Imaging has recently grown popular among multiple surgical specialties, including colorectal, plastic, endocrine, ophthalmologic, and vascular surgery, due to its ability to quickly and accurately assess tissue perfusion and guide intraoperative decision making. To our knowledge, the use of SPY imaging in urologic reconstructive surgery has yet to be reported. We present a case in which SPY imaging was used intraoperatively to assess perfusion of an ileocecal anastomosis and a segment of bowel prior to creation of a continent urinary diversion following radical cystectomy.

Techniques for Imaging Vascular Supply of Peripheral Nerves

“…Laser angiography has been used successfully to monitor tissue perfusion in a variety of settings, including colorectal, plastic, endocrine, ophthalmologic, and vascular surgery. 54 While the majority of literature is focused on tissue resection and/or flap design, one case series described visualization of the sciatic nerve perivascular system in three pediatric sarcoma patients during limb salvage surgery. 16 While depth of structures limit its application in mapping common arterial inputs and/or venous drainage, laser angiography may be clinically useful in visualizing these vessels intraoperatively.…”
