[Retroperitoneal laparoscopic surgery; initial experience in the Hospital La Paz].

We present the initial results of retroperitoneal laparoscopic surgery in the Hospital Universitario La Paz from July 2004 to December 2004. The program started after 2 years of pelvic laparoscopy surgery practice. The initial experience has been so good that we have reduced the contraindications for this technique and we have increased the number of laparoscopic surgery cases.
