摘要

Despite being widely adopted, the laparoscopic approach to radical and partial nephrectomy is still burdened by high rates of hemorrhagic complications, which require blood transfusions and conversion to open surgery with increased morbidity. While pre-operative renal artery embolization (PRAE) can prevent intraoperative blood loss and vascular injuries, its prophylactic use is still a matter of debate. This study evaluated the safety and efficacy of PRAE in overcoming the main pitfalls of laparoscopy, which are related to the absence of tactile feedback.Data from 48 patients who underwent laparoscopic nephrectomy for cancer (34 laparoscopic radical nephrectomy (LRN) and 14 "off-clamp" laparoscopic partial nephrectomy (LPN) after selective and superselective PRAE, respectively) were retrospectively evaluated.The overall median blood loss was 50 ml and only 2 patients (4%) required one unit of blood products. While conversion to open surgery was not required in the LPN group, one case in the LRN group was converted to open surgery due to intraoperative incoercible bleeding from an unrecognized, and thus not embolized, aberrant inferior polar artery. Post-embolization syndrome occurred in 7 patients (15%), resulting in mild flank pain and nausea. No patients in the LPN group experienced new onset of acute renal failure.Our experience supports pre-operative renal embolization as a safe, minimally invasive procedure that is effective for reducing perioperative bleeding in the laparoscopic setting.
