title: Retroperitoneoscopy: a laparoscopic approach for adrenal and renal surgery.
abstract: OBJECTIVE
  Retroperitoneoscopy has gained acceptance for urologic surgery. We assessed the safety and efficacy of this procedure for renal and adrenal surgery.
  
  
  METHODS
  Since December 1994, 20 patients (18 to 75 years old) have undergone laparoscopic adrenalectomy and nephrectomy, including simple nephrectomy in 8, partial nephrectomy in 1, radical nephrectomy in 2, tumorectomy with cyst excision in 1, and adrenalectomy in 8. The retroperitoneal space was created by blunt dissection with the index finger, completed by insufflation, without balloon dissection.
  
  
  RESULTS
  Average kidney size was 65 m (range 50 to 108), and average adrenal tumor size was 31 mm (range 20 to 40). The average operating time was 127 minutes (range 60 to 180) for nephrectomy and 84 minutes (range 45 to 140) for adrenalectomy. The average hospital stay was 3 days (range 1 to 7) for nephrectomy and 2.4 days (range 1 to 4) for adrenalectomy. Average blood loss was 65 mL for both nephrectomy and adrenalectomy. Conversion from the laparoscopic procedure to open surgery was never required. Peritoneal effraction and ureteral injury occurred in only 4 patients and 1 patient, respectively.
  
  
  CONCLUSIONS
  The laparoscopic retroperitoneal approach is safe and effective for simple renal nephrectomy and for excision of small adrenal tumors. Perioperative morbidity and hospital stay are reduced.
