[Laparoscopic approach in partial nephrectomy].
Except for segmental parenchymal atrophies, partial nephrectomy is more and more often indicated when treating isolated small renal tumours. During the last few years this technique has been increasingly accepted for the excision of tumours less than 4 centimetres. In order to diminish the operative morbidity, the laparoscopic approach has been proposed. During the last decade, laparoscopic partial nephrectomy "has come to maturity" and this technique is now well standardized. Knowledge and operative skills are required for both trans-peritoneal and extra-peritoneal route. Extra-peritoneal approach is more suitable for posterior lesions or at the level of the lower pole while the trans-peritoneal route is preferred in case of tumours near the renal hilum or on the anterior surface. Different methods offering temporary arrest of renal perfusion have been elaborated. There is a clear tendency for renal parenchyma sectioning without the use of any kind of thermal energy. This allows a better identification of renal lesions. Sectioned collecting system, blood vessels and renal parenchyma are systematically sutured. Despite its complexity, this technique has become reproducible and reliable in specialized laparoscopic centres.
