In this method a small incision was made to approach the retroperitoneal space prior to setting trockers and thereafter a LAPDISC was placed in the incision to start the retroperitoneoscopic procedure. In this study we compared the outcomes between the combined small skin incision method A method hereinafter and the conventional method B method hereinafter . material and methods Among the cases of T1N0M0 suspicious renal cell carcinoma treated at Yokohama City University between May 2003 and June 2009 the A method was performed in 51 cases and the B method was performed in 33 cases. The factors in the outcomes compared between the A and B methods were the duration of procedure volume of bleeding volume of transfusion weight of the specimen incidence of peritoneal injury rate of conversion to open surgery and perioperative complications. results The duration of the procedure was 214.4 46.9 minutes in the A method group and 208.1 36.4 minutes in the B method group p 0.518 . The volume of bleeding and the weight of the specimen were 105.5 283.2 ml and 335.1 137.4 g in the A method group and 44.8 116 ml p 0.247 and 309.2 126 g p 0.385 in the B method group. There was no significant difference in all factors analyzed. conclusion The A method would be highly possible to produce stable results even during the introduction period when the staff and
