Pure conventional laparoscopic radical nephrectomy with level II vena cava tumor thrombectomy

Area of Science:

• Urological Oncology
• Minimally Invasive Surgery

Background:

• Surgical management of renal cell carcinoma with inferior vena cava tumor thrombus (IVTT) presents significant technical challenges.
• Laparoscopic techniques are increasingly explored for complex oncological procedures.

Observation:

• Two patients with level II IVTT underwent pure conventional laparoscopic radical nephrectomy and thrombectomy.
• Intraoperative laparoscopic ultrasonography was utilized for thrombus detection and confirmation of complete removal.
• Procedures were performed via retroperitoneal (right) and transperitoneal (left) approaches.

Findings:

• Both laparoscopic procedures were successfully completed without conversion to open surgery.
• Patients showed no radiographic evidence of recurrence during the follow-up period.
• The study highlights the feasibility of a pure laparoscopic approach for selected cases of renal cell carcinoma with level II IVTT.

Implications:

• Pure conventional laparoscopic management of renal cell carcinoma with level II IVTT is achievable in carefully selected patients.
• This approach may broaden the application of laparoscopic surgery in complex urological oncology.
• Further multicenter prospective randomized trials are necessary to validate the benefits of this minimally invasive technique.
