[A new technique for extended left nephrectomy (author's transl)]

Description of a technique for extended left nephrectomy, the originality of which lies in the approach to the pedicle via a supra-mesocolic way. Opening of the posterior cavity of the epiploons, upward displacement of the pancreas and downward displacement of the mesocolon give wide exposure of the vessels and sub-pedicular lymph node dissection is possible under good conditions. The spleen is less exposed than in the classical approach. Only experience will make it possible to fix the limitations and role of this technique which the authors have been using for the past two years.
