Update on partial nephrectomy and novel techniques.

The treatment of renal tumors with the technique of partial nephrectomy continues to evolve. The relevant literature reviewed confirmed the excellent oncological outcomes associated with partial nephrectomy in properly selected patients. In addition, much data is being accumulated regarding the safety and efficacy of this technique via a laparoscopic approach. With either approach, the chance for renal preservation would appear to be a major benefit while "non-hilar" clamping techniques during the open approach may maximize the likelihood for maintenance of long-term renal function.
