title: [Subsequent retroperitoneoscopy for patients with previous ipsilateral retroperitoneal surgery].
abstract: OBJECTIVE
  To evaluate the feasibility and clinical results of subsequent retroperitoneoscopic surgery for patients with previous ipsilateral retroperitoneal surgery through frank incision.
  
  
  METHODS
  A total of 10 patents were selected for subsequent laparoscopic surgery through retroperitoneal approach. Among them, there were recurrent renal cysts (n = 4) including a history of open surgery (n = 1) and retroperitoneal surgery (n = 3) and nonfunctional kidneys (n = 6) including open nephropyelopolasty (n = 3), retroperitoneoscopic nephropyelopolasty (n = 1) and retroperitoneoscopic ureterolithotomy (n = 2). The mean surgical duration was (12-85) 38.6 months. All patients underwent retroperitoneoscopy. Decortication was performed for renal cysts and nephrectomy for nonfunctional kidneys.
  
  
  RESULTS
  All operations were successfully performed with a mean surgical duration of 97 (40-185) minutes and a mean volume of blood loss 125 (20-460) ml. Among 4 cases with intraoperative peritoneal rupture, one case had renal cyst on ventral side. After enlargement, the procedure was performed through peritoneal cavity. The mean postoperative hospital stay was 5.6 (3-9) days. Nine patients received a mean follow-up period of 21.5 (3-47) months. All symptoms were relieved without any occurrence of postoperative complications.
  
  
  CONCLUSIONS
  For patients with previous ipsilateral retroperitoneal surgery, retroperitoneoscopy may be feasible for properly selected cases.
