To our knowledge we report the initial clinical series of laparoscopic radical nephrectomy for renal cell carcinoma associated with level I renal vein thrombus. Materials and Methods: At our 2 institutions 8 patients each underwent laparoscopic radical nephrectomy for level I microscopic renal vein thrombus (group 1) and level I gross thrombus (group 2). In all 8 group 2 patients the level I thrombus was preoperatively diagnosed by computerized tomography. Mean renal tumor size in groups 1 and 2 was 7.8 and 12.4 cm., respectively. After controlling the renal artery the renal vein was secured by firing an endoscopic gastrointestinal anastomosis stapler on its collapsed, uninvolved proximal part adjacent to the vena cava. Intraoperative, postoperative and pathological parameters were assessed in the 2 groups. Results: In group 1 laparoscopic radical nephrectomy was technically successful in all 8 patients. Mean operative time was 3.1 hours, mean estimated blood loss was 382 cc and mean hospital stay was 1.9 days. In 1 patient each a soft tissue and a vascular margin was positive for cancer. At a mean follow up of 19.5 months (range 2 to 36) metastatic disease occurred in 3 cases (38%). In group 2 laparoscopic radical nephrectomy was technically successful in 7 cases with open conversion in 1. Mean operative time was 3.3 hours, mean estimated blood loss was 354 cc and mean hospital stay was 2.3 days. Surgical soft tissue and the renal vein vascular margin of the transected vein were negative for cancer in all 8 cases. At a mean followup of 9.4 months (range 5 to 16) pulmonary metastasis developed in 1 patient (13%). Conclusions: Although it is an advanced procedure, laparoscopic radical nephrectomy in patients with level I renal vein thrombus is feasible, safe and follows established oncological principles.
