Complex robotic nephrectomy and inferior vena cava tumor thrombectomy: an evolving landscape.

Abstract

Robotic nephrectomy for complex renal masses and in the setting of inferior vena cava (IVC) tumor thrombus has been shown to be a well tolerated and reproducible surgical option. Recent developments in such procedures will be discussed as they continue to evolve. Multiple case series have demonstrated the application of robotic surgery in the management of the most complex renal tumors and for IVC thrombi with acceptable oncologic and perioperative outcomes. Prior to the advent of robotic surgery, massive tumors, contiguous organ invasion, need for lymphadenectomy, and IVC tumor thrombus were thought by many to require open surgery. Since 2011, several studies have reported robotic nephrectomy for complex tumors with recent comparisons of robotic and open approaches finding similar oncologic and survival outcomes but with shorter length of stay (LOS) and less blood loss with robotic surgery. Robotic surgery is a feasible and well tolerated alternative to open surgery for the management of complex renal tumors and IVC thrombi. The potential benefits of shorter LOS, less blood loss, and earlier convalescence suggest this approach should continue to be evaluated. Patient selection and surgeon experience are of paramount importance.
