Comparison of laparoscopic versus open nephrectomy in the pediatric population

PURPOSE: Laparoscopic renal surgery has become an accepted approach for benign disease in adults. We compare our experience with laparoscopic and open nephrectomy in a pediatric population. MATERIALS AND METHODS: A total of 10 pediatric patients underwent laparoscopic nephrectomy or nephroureterectomy and an additional 10 consecutive children underwent similar open procedures. All patients had benign disease and were treated at a single institution. Medical records were reviewed retrospectively for relevant clinical data. RESULTS: Planned surgery was completed in all cases. There were no conversions to open surgery in the laparoscopic group. Mean operative time was 175.6 versus 120.2 minutes (p = 0.01) and mean hospital stay was 22.5 versus 41.3 hours (p = 0.03) in the laparoscopic and open nephrectomy groups, respectively. Blood loss was not statistically different. Analgesic use was qualitatively less in the laparoscopic nephrectomy group. CONCLUSIONS: Laparoscopic nephrectomy and nephroureterectomy may be performed safely in children. While operative time was somewhat longer in our initial laparoscopic series, postoperative hospital stay was significantly shorter than for open surgery. Further experience with this technique is warranted.
