title: [Laparoscopic radical nephrectomy for renal cell carcinoma--transperitoneal anterior approach].
abstract: OBJECTIVE
  To evaluate the usefulness of transperitoneal anterior approach in laparoscopic radical nephrectomy for patients with renal cell carcinoma.
  
  
  METHODS
  Ten patients (Eight males and two females) with small renal cell carcinoma less than 7 cm in diameter were treated with laparoscopic radical nephrectomy between June 1997 and May 1999. Clinical stage was T1aN0M0 in 6 cases and T1bN0M0 in 4 cases.
  
  
  METHODS
  Of the 10 patients, the initial four received preoperative embolization of the renal artery. Under general anesthesia laparoscopic radical nephrectomy via transperitoneal anterior approach was performed in all patients. This procedure facilitates initiated early access to the renal vessels as does open radical nephrectomy. The kidney was dissected en bloc with Gerota's fascia and delivered from the small skin incision without morcellation.
  
  
  RESULTS
  Two patients needed conversion to open surgery. The mean operating time of eight patients except for conversion cases was 247 minutes and the mean blood loss was 258 ml. There was no major complication associated with laparoscopic procedure.
  
  
  CONCLUSIONS
  Transperitoneal anterior approach in laparoscopic radical nephrectomy is a suitable and useful procedure for the treatment of small renal cell carcinoma because it enables us to avoid possible tumor manipulation by early access to the renal vessels as open radical nephrectomy.
