title: [Retroperitoneal laparoscopic enucleation of the renal hamartoma].
abstract: OBJECTIVE
  To investigate the operative technique and the clinical value of retroperitoneal laparoscopic enucleation of the renal hamartoma.
  
  
  METHODS
  Twenty-five patients of renal hamartoma received retroperitoneal laparoscopic enucleation. The patients were placed in lateral decubitus position. All laparoscopic surgical procedures were performed retroperitoneally using 3 port-sites. The tumor was exposed and resected along the edge, and the tumor clipped out with a lithotomy forceps. The renal hamartoma was confirmed through a pathological diagnosis during the operation. The resection surface was sutured with fibrin and absorbable hemostatic gauze.
  
  
  RESULTS
  The operations were finished successfully in all patients. The diameter of tumors ranged from 1.8 cm x 2.0 cm to 4.5 cm x 4.9 cm. The operative time was 50 - 90 (mean=70) min. The blood loss was 30 - 80 (mean=55) mL. The hospital stay was 7 - 9 (mean=8) days.
  
  
  CONCLUSIONS
  Retroperitoneal laparoscopic enucleation of the renal hamartoma is safe and effective, whose advantages include minimal invasive, less blood loss, short hospital stay, and rapid convalescence.
