Laparoscopic nephrectomy is a new procedure which remains to be evaluated in adults and children. This technique enables the reduction of parietal complications and sequelae. The majority of indications, e.g. renal dysplasia,destroyed kidneys due to obstructive or refluxing uropathy, are suitable for laparoscopic nephrectomy. Contraindications are Wilm’s tumor and trauma which represent only 20% of nephrectomies in our experience. As in open surgery, a retroperitoneal approach seems more logical and better adapted than a transperitoneal approach to perform nephroureterectomy for benign disease. From August 1993 to December 1995, we attempted 18 retroperitoneal laparoscopic nephrectomies in children aged from 3 months to 14 years. The patient is placed in a lateral position, and after creation of a retropneumoperitoneum under direct vision control without balloon dissection, three or four ports are needed, renal vessels are dissected, then clipped or coagulated if small. Destroyed kidneys are generally of small size, so they can be extracted via a 10- or 12-mm cannula site without morcellation. Operative time is 35-210 min (median 106 min). There were no major complications and only one conversion. In conclusion, retroperitoneal laparoscopic nephrectomy in children is a feasable and safe procedure in well-trained hands.
