Laparoscopic partial nephrectomy: Newer trends.
OBJECTIVE
To report the advances in laparoscopic partial nephrectomy (LPN) for renal masses with emphasis on technically challenging cases.


METHODS
Literature in the English language was reviewed using the National Library of Medicine database using the key words kidney, renal, tumor, nephron sparing surgery, and laparoscopic partial nephrectomy, for the period between 1993 and 2009. Over 500 articles were identified. A total of 50 articles were selected for this review based on their relevance to the evolution of the technique and outcomes, as well as expanding indications for LPN.


RESULTS
In expert hands, LPN is safe and effective for central tumors, completely intrarenal tumors, hilar tumors, tumor in a solitary kidney, large tumors requiring heminephrectomy, cystic tumors, multiple tumors, obese patients, and even incidental stage >/= pT2 tumors. Perioperative outcomes and 5-year oncologic outcomes after LPN are comparable to open partial nephrectomy (OPN).


CONCLUSIONS
In experienced hands indications for LPN have expanded significantly. In 2009, advanced LPN remains a skill-intensive procedure that can nevertheless provide excellent outcomes for patients with renal tumors.
