Dr. James Porter is the Director of Robotic Surgery at Swedish Medical Center in Seattle. He performs prostate and kidney cancer surgeries using a DaVinci robotic surgical system guided by ultrasound. In this fascinating 30 minute video, Dr. Porter talks through three partial nephrectomy cases to demonstrate how he uses a drop-in ultrasound transducer to localize the tumor and determine the margin and depth of resection.
The surgery video shows the ultrasound image from the transducer as well as the endoscopic view of the operations featuring the transducer, scissors, and cauterizer in action around the tumors. Interesting moments include:
- (11:50) Dr. Porter uses color Doppler to highlight a blood vessel at the base of a tumor
- (17:20) The drop-in transducer is used to localize the tumor among the sinus fat of the kidney
- (21:20) Ultrasound is used to determine tumor depth and margins
