Study Findings Confirm New F.A.S.T Procedure Achieves Same Results as Standard Robotic Partial Kidney Surgery in Much Less Time — Even with Complex Tumors.

NEW YORK (Aug 30, 2012)

An innovative procedure to streamline a robotic partial nephrectomy, the surgical removal of a kidney tumor, significantly reduces the critical time the kidney is without blood flow, otherwise known as warm ischemia time (W.I.T), by nearly 25 percent, according to an analysis led by researchers at NewYork-Presbyterian Hospital/Columbia University Medical Center.

The study, published in the Journal of Endourology in June, confirms that the procedure, known as first assistant sparing technique (F.A.S.T), achieves the same results as standard robotic partial nephrectomy surgery in much less time, regardless of tumor size, location, or complexity. The F.A.S.T incorporates steps typically performed by surgical assistants into the robotic process.

F.A.S.T Opens Door to Minimally Invasive Surgery for Complex Renal Tumors

"By incorporating F.A.S.T into our robotic approach, for the first time we were able to cut W.I.T down to an average of 15 minutes — and 18 minutes for more complicated tumors," said the lead author and investigator, Dr. Ketan K. Badani, chief of robotic and minimally invasive surgery at NewYork-Presbyterian Hospital/Columbia University Medical Center and associate professor of urology at Columbia University College of Physicians and Surgeons. "As a result, we're able to offer a minimally invasive partial nephrectomy to almost anyone with a renal tumor, regardless of its size or complexity."

The study results were confirmed by comparing F.A.S.T with standard robotic techniques in a retrospective six-month review of 44 patients who underwent robotic partial nephrectomy. F.A.S.T was as efficient as the standard robotic approach at completely excising a tumor with no positive surgical margins, a measure of oncological efficacy, despite tumor size or location, or other complicating factors.

Kidney Surgery: A Race Against Time to Restore Blood Flow

A partial nephrectomy entails removing the tumor while preserving the kidney. During the procedure, blood flow must be temporarily cut off from the kidney. "As a rule of thumb," said Dr. Badani, "the maximum time blood flow can be cut off from the kidney is 30 minutes, to avoid irreversible damage. But studies suggest that every minute blood flow to the kidney is blocked can have a cumulative effect on kidney function." With F.A.S.T, a series of steps typically performed by surgical assistants — ultrasound, clamping to cut off and restore blood flow to the kidney, passing of needles, and stitches — can be incorporated into the robotic process, shaving off critical WIT minutes.

The F.A.S.T approach evolved over the course of about two years, as Dr. Badani and his colleagues continually looked for new timesaving steps. "I work in an environment where we're constantly trying to improve upon what we're doing," he said. "Two years from now, we hope to have an even better technique."

The team of urologic surgeons at NewYork-Presbyterian Hospital/Columbia University Medical Center performing partial nephrectomies for renal tumors includes Ketan Badani, M.D., director of robotic surgery, Mitchell C. Benson, M.D., chair of the department of Urology, James McKiernan, M.D., director of urologic oncology and G. Joel de Castro, M.D., director of urologic oncology NewYork-Presbyterian/The Allen Hospital.
