Li Q, et al. - Experts seek to ascertain the effect of intraoperative ultrasound on robotic-assisted radical nephrectomy with inferior vena cava (IVC) tumor thrombectomy in renal cell carcinoma (RCC). Between December 2017 and July 2018, intraoperative records of 27 patients with RCC and invasion of the IVC who underwent robotic-assisted nephrectomy with tumor thrombectomy at our center were retrospectively examined. They extracted diagnostic utility and impact of intraoperative transesophageal echocardiography (TEE), intraoperative robotic-assisted ultrasonography, and intraoperative contrast-enhanced ultrasound (CEUS) on surgical management from the surgical notes and intraoperative ultrasound reports. Twenty-seven individuals with thrombus had an intraoperative ultrasound. Intraoperative ultrasound was found to be a safe, minimally invasive technique that can give accurate real-time information regarding the presence and extent of IVC involvement and guidance for placement of a vena cava clamp, establishing the character of the thrombus to plan an optimal surgical approach.
