Robot-assisted radical nephrectomy and inferior vena cava tumor thrombectomy using the novel surgical robot platform, hinotori: Initial experience with two cases.

Introduction: A newly developed surgical robot system, hinotori, with various unique advantages has been in clinical use in Japan; however, there have not been any studies of robot-assisted radical nephrectomy and inferior vena cava tumor thrombectomy using hinotori.

Case Presentation: We describe two male patients aged 67 and 76 years old with right renal cell carcinoma and a level II and I inferior vena cava tumor thrombus, respectively, undergoing robot-assisted radical nephrectomy and inferior vena cava tumor thrombectomy using hinotori. Both operations were successfully completed with a purely robotic procedure without any major perioperative complications, resulting in the following findings: time using robotic system, 158 and 156 min; total operative time, 228 and 214 min; estimated blood loss, 535 and 200 mL, respectively.

Robot-assisted radical nephrectomy and inferior vena cava tumor thrombectomy: Initial experience in Japan.

Introduction: Open surgical approach remains the standard treatment for renal cell carcinoma with an inferior vena cava tumor thrombus. In recent years, however, robot-assisted radical nephrectomy and inferior vena cava tumor thrombectomy have emerged as minimally invasive alternatives to conventional open surgery.

Case Presentation: Here, we describe a 76-year-old female patient with right renal cell carcinoma with a level I inferior vena cava thrombus undergoing robot-assisted radical nephrectomy and inferior vena cava tumor thrombectomy, which was successfully completed with a purely robotic procedure, resulting in the following outcomes: console time,167 min; total operative time, 211 min; and estimated blood loss, 150 mL.
