Radical nephrectomy with vena caval thrombectomy: a contemporary experience

Area of Science:

• Urology
• Surgical Oncology
• Nephrology

Background:

• Radical nephrectomy and vena caval thrombectomy are complex procedures for advanced kidney cancer.
• Managing inferior vena cava (IVC) thrombus requires specialized surgical expertise.
• The use of bypass techniques in IVC thrombectomy can increase morbidity.

Purpose of the Study:

• To evaluate the contemporary experience at Memorial Sloan-Kettering Cancer Center with radical nephrectomy and vena caval thrombectomy.
• To assess the safety and efficacy of an off-bypass surgical approach for IVC thrombus resection.
• To report on postoperative complications, oncological outcomes, and survival rates.

Main Methods:

• Retrospective review of patients undergoing radical nephrectomy and vena caval thrombectomy without bypass.
• Data collection included intraoperative findings, pathological details, and postoperative outcomes.
• Analysis of complications, recurrence rates, and long-term survival.

Main Results:

• 78 patients underwent off-bypass radical nephrectomy with IVC thrombectomy (1989-2009).
• Median operative time was 293 minutes with median blood loss of 1300 mL.
• 18% experienced major complications, with a 5-year survival of 48%.

Conclusions:

• Radical nephrectomy with vena caval thrombectomy is associated with acceptable morbidity and mortality.
• Long-term survival is achievable for select patients.
• Off-bypass resection is a safe and effective approach for many level 3/4 IVC thrombi.
