Since 1996, 300 laparoscopic nephrectomies (200 radical and 80 partial) for renal cancer have been done at the Institute Montsouris.

The 80 laparoscopic partial nephrectomies have been performed for small cancers (<6cm).

The average age was 50 years, 60 % men and 40% women.

In 80% of cases the tumor was detected by abdominal ultrasonography without symptoms like hematuria or flank pain.

The operation time 118 minutes (from 45 to 185 mn) the blood loss was 291 ml and the transfusion rate 5% (mostly for the very big tumor or obese patients) ; the post op hospital stay was 4.5 days

No death, no cardiovascular or pulmonary complications.

Oncological results: to day no patient had a local recurrence (0%), two have metastasis (2%).

Functional results: the laparoscopic radical nephrectomy for tumor was never responsible for a renal failure.
