title: Feasibility of laparoscopic approach in management of xanthogranulomatous pyelonephritis.
abstract: OBJECTIVE
  To report the feasibility of the laparoscopic approach for management of xanthogranulomatous pyelonephritis (XGP).
  
  
  METHODS
  From 2002 to 2005, 11 patients underwent laparoscopic (n = 7) or hand-assisted laparoscopic (n = 4) nephrectomy by a single surgeon for pathologically confirmed XGP. The preoperative presentation, operative details, postoperative recovery, and complications were recorded.
  
  
  RESULTS
  A total of 5 men and 6 women were included in this study, and the mean patient age was 51 years (range 28 to 78). All cases began with the laparoscopic approach (6 left and 5 right). Four cases were converted to the hand-assisted technique because of the difficulty in progression, but no case required conversion to open nephrectomy. The mean operative time was 157 minutes (range 101 to 201), with a mean estimated blood loss of 217 mL (range 50 to 440). No intraoperative complications occurred. The mean hospital duration was 2.4 days (range 1.5 to 4). Four patients had postoperative complications, including two with an ileus, one with a persistent fever requiring intravenous antibiotics, and one with a renal fossa abscess requiring percutaneous drainage. All specimens were pathologically confirmed to be XGP.
  
  
  CONCLUSIONS
  Laparoscopic nephrectomy for XGP is complicated and more technically demanding than the laparoscopic nephrectomy for noninfectious etiologies. Consideration should be made for using a hand port should the laparoscopic procedure fail to progress in a satisfactory manner. In experienced hands, the laparoscopic approach presents a reasonable surgical option for the treatment of XGP. For the novice laparoscopist, however, the open approach should remain the modality of choice.
