Laparoscopic partial nephrectomy.

Laparoscopic partial nephrectomy (LPN) compares favorably to traditional open nephron-sparing surgery (NSS) in terms of oncologic and surgical principles for kidney tumors. Studies have shown the modality to be feasible with similar oncologic efficacy and superior renal functional outcomes compared with laparoscopic radical nephrectomy (LRN) for tumors. The main advantages of LPN include marked improvements in estimated blood loss, decreased surgical site pain, shorter postoperative convalescence, better cosmesis, and nephron preservation. This review article evaluates the literature regarding LPN and discusses the main steps of the operation, the perioperative workup and management, surgical complications, and its role in the surgical management of kidney masses.
