[Nephron-sparing therapy for renal tumors].

In this article up-to-date, nephron-sparing therapy for renal cell cancer such as radical tumor nephrectomy, partial resection or enucleation is summarised. The results of open and laparoscopic partial nephrectomy and tumor enucleation are presented. Problems and complications associated with the techniques are reviewed. There are as yet no randomized, controlled trials and most published studies show retrospective data. Further new alternative techniques in nephron-sparing therapy like cryosurgery and radiofrequency ablation are presented.
