Expanding the indications for laparoscopic radical nephrectomy.
OBJECTIVE
Laparoscopic radical nephrectomy is an established treatment for patients with clinical T1 renal cell carcinoma who are unsuitable for nephron-sparing surgery. In this review we summarize the expanding indications for laparoscopic nephrectomy, including large tumors, locally advanced disease, venous thrombi and cytoreductive surgery.


RESULTS
Laparoscopic nephrectomy remains the foremost conventional laparoscopic procedure in urologic surgery. Multiple studies have demonstrated the feasibility of laparoscopic radical nephrectomy for stage T2 tumors, showing less morbidity and earlier return to activity compared to the open approach. Confirmation of durable oncologic control requires randomized prospective trials with longer follow-up. With growing experience, laparoscopic surgery has been extended to patients with renal cell carcinoma associated with limited local invasion and lymph node metastases. Experimental studies demonstrate the technical feasibility of laparoscopic radical nephrectomy in the presence of renal vein and inferior vena cava thrombi. In well-selected patients with metastatic renal cell carcinoma, laparoscopic cytoreductive nephrectomy can be performed safely, with less morbidity than open nephrectomy.


CONCLUSIONS
Minimally invasive surgery results in significantly less postoperative morbidity than does open surgery. The intermediate oncologic outcomes of laparoscopic radical nephrectomy for advanced renal cell carcinoma are comparable to those historically achieved with open radical nephrectomy. Longer follow-up is needed to confirm survival equivalence.
