Retroperitoneal laparoscopic nephrectomy in children: preliminary report of six cases.
Laparoscopic nephrectomy is a new procedure that must be evaluated in adults and children. This technique allows a reduction in complications and sequelae. The majority of indications, such as renal dysplasia and destroyed kidneys due to obstructive or refluxing uropathy, are suitable for laparoscopic nephrectomy. Contraindications are Wilms' tumor and trauma, which represent only 20 percent of nephrectomies in our experience. As in open surgery, to perform nephroureterectomy for benign disease, a retroperitoneal approach seems more logical than transperitoneal approach, which is the usual approach for laparoscopic surgeons. We have attempted six retroperitoneal laparoscopic nephrectomies in children from 3 months to 14 years old. The patient is positioned in a lateral position after creation of a retropneumoperitoneum under visual control; three or four ports are needed and 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 ranges from 35 to 210 mm (median 120 mm). We have had no complications or conversions. Retroperitoneal laparoscopic nephrectomy in children is a feasible and safe procedure in well-trained hands.
