By: Zenalux, Tulane University Partial nephrectomy is gaining traction in kidney cancer patients because only the diseased part of the kidney is being removed as opposed to the entire organ. However, when the main artery that feeds the kidney is clamped during surgery, blood flow is cut off to the entire kidney rather than just the diseased area. “Starving the kidney for oxygen can cause poor function after surgery, so one of the new techniques is to selectively clamp the artery that feeds the tumor so the rest of the kidney maintains oxygen flow. The challenge becomes determining if you've got the correct artery, and from that point, whether or not you’ve stopped blood flow into the area that needs to be removed,” explained Quincy Brown, Assistant Professor of Biomedical Engineering at Tulane University and co-author of the study. “By using the Zenascope as a diagnostic tool to determine the presence or lack of bloodflow, we are eliminating the guesswork and the surgeon is able to ensure selective ischemia.” This highly successful feasibility study was also conducted laparoscopically, thus supporting a minimally invasive surgical procedure. Commented Dr. Jesko von Windheim, CEO of Zenalux: “This study was the first of its kind conducted using this type of technology—quantitative optical spectroscopy measurement— The Zenascope® system is a specialized, real-time, non-invasive, diagnostic device that shines white light on opaque target media and then measures and analyzes the reflected signal. The Zenascope system can also easily be tuned to include additional absorbers of interest. This unique capability is expected to enable improved diagnosis, better treatment, and ultimately cost reduction in the health care system. The system is currently designated for investigational use only. Other application areas currently include accelerating feedback in drug discovery; breast tumor margin assessment; response to therapy; breast biopsy; cervical cancer detection; and head and neck cancer detection.
