Simple Enucleation is Equivalent to Traditional Partial Nephrectomy for Renal Cell Carcinoma: Results of a Nonrandomized, Retrospective, Comparative Study.

The excision of the renal tumor with a substantial margin of healthy parenchyma is considered the gold standard technique for partial nephrectomy. However, simple enucleation showed excellent results in some retrospective series. We compared the oncologic outcomes after standard partial nephrectomy and simple enucleation.To our knowledge this is the first multicenter, comparative study showing oncologic equivalence of standard partial nephrectomy and simple enucleation
