title: Retroperitoneal laparoscopic living-donor nephrectomy. Preliminary results.
abstract: OBJECTIVE
  Living-donor nephrectomy is performed via a standard flank approach during open surgery in contrast to laparoscopy where kidneys are procured transperitoneally. Being more familiar with retroperitoneal laparoscopy for the surgery of the upper urinary tract, we investigated the feasibility of live donor nephrectomy by this approach.
  
  
  METHODS
  We performed laparoscopic retroperitoneal left-sided nephrectomy in 3 living donors. The patients were placed in lumbotomy position. The retroperitoneal space was developed with blunt finger dissection, through a 2-cm mini-lumbotomy under the 12th rib in the posterior axillary line. 5 trocars were inserted. After primary access to the renal artery and vein, these were dissected to their junctions with the aorta and inferior vena cava, respectively, before freeing the kidney of its perinephric attachments. The kidney was delivered manually, through the slightly enlarged initial subcostal incision.
  
  
  RESULTS
  The average duration of surgery was 83 min; warm ischemia time less than 5 min. Average blood loss was 120 cm(3). Donors did not present any postoperative morbidity and were discharged after an average of 2.3 days. Mean analgesic requirement was 5 mg morphine sulphate equivalent (0-15). Average convalescence was 13.3 days (10-18). All 3 kidneys harvested laparoscopically had immediate function with urine production after graft revascularization; serum creatinine levels returned to normal within 1 week. The first patient presented ureteral stenosis 2 months after surgery. He underwent ureteropyeloplasty using his native ureter.
  
  
  CONCLUSIONS
  Laparoscopic living-related-donor nephrectomy become a new standard for organ harvesting. Our data suggest that retroperitoneal laparoscopic donor nephrectomy may represent a reasonable option in centers in which more extensive experience has been accumulated with retroperitoneal than with transperitoneal laparoscopy for the surgery of the upper urinary tract.
