title: [Which surgical technique should we perform for benign renal disease in children?].
abstract: OBJECTIVE
  The aim of this paper is to analyze our experience in different surgical techniques to perform a nephrectomy for benign renal diseases in children.
  
  
  METHODS
  From 1993 to 2005 we have performed 98 nephrectomies. We have three groups of patients depending on the surgical technique: open nephrectomy (ON), transperitoneal laparoscopic nephrectomy (TLN) and retroperitoneal laparoscopic nephrectomy (RLN). ON was performed in 36 patients. Mean age was 3.3 years. TLN was performed in 39 patients. Mean age was 4.7 years old. RLN was performed in 23 patients. Mean age was 3.6 years old. Criteria to nephrectomy was a renographic function under 19%. We have compared the three surgical techniques in relation with surgical time and mean hospital stay.
  
  
  RESULTS
  Mean operative time was 126.2 minutes in ON, 132.3 minutes in TLN and 134.1 minutes in RLN. Mean stay was 5.02 days in ON, 2.35 days in TLN and 1.86 days in RLN. The median hospital stay of the ON group is significantly longer than that of NLT and NR groups (p < 0.05). However, there are no differences related to surgical time between all the groups.
  
  
  CONCLUSIONS
  Nephrectomy may be performed for benign disease in children using less invasive surgical techniques. They are associated with minimal morbidity, minimal postoperative discomfort, improve cosmesis and a shorter hospital stay. However, we haven't found differences between TLN and RLN.
