title: Minimally invasive nephron-sparing surgery (MINSS) for renal tumours part I: laparoscopic partial nephrectomy.
abstract: OBJECTIVE
  To review the evolution and current status of extirpative methods (laparoscopic partial nephrectomy [LPN]) of minimally invasive nephron-sparing surgery (MINSS) for renal tumors.
  
  
  METHODS
  The English language literature of the past 10 yr was reviewed by using the National Library of Medicine database and the following keywords: kidney, laparoscopic partial nephrectomy, minimally invasive, nephron-sparing surgery, renal, and tumor. Over 275 papers were identified. Of these, 55 papers were selected for this review on the basis of their contribution in advancing the field with regards to (1) evolution of concepts, (2) development and refinement of techniques, and (3) intermediate- and long-term clinical outcomes of LPN.
  
  
  RESULTS
  Open partial nephrectomy (OPN) is the reference standard for nephron-sparing surgery against which all MINSS techniques should be measured. With available skills for time-sensitive intracorporeal suturing, LPN provides perioperative results and long-term oncologic and functional outcomes comparable to the reference standard, with significantly decreased patient morbidity. The initial 5-yr data of 50 patients has just become available, and shows overall and cancer-specific survival of 84% and 100%, respectively. As global experience with this technique increases, data need to be prospectively accrued, and long-term cancer cure rates should be compared with the reference standard.
  
  
  CONCLUSIONS
  As of this writing, the technique and global acceptance of LPN is evolving, although it remains restricted by the complexity of laparoscopic renal reconstruction. In expert hands, cancer cure and renal function outcomes are similar to OPN.
