Retroperitoneoscopic Nephrectomy in Pediatric Patients.

Minimally invasive surgery (MIS) in pediatric population is becoming more and more popular among pediatric urologists and now it can be considered the best treatment for nephroureterectomy that is one of the most frequent urological procedures. The main indications to MIS ureteronephrectomy in children are congenital or acquired benign conditions such as nonfunctional and/or damaging kidney, renal dysplasia, and destroyed kidneys due to obstructive or refluxing uropathy. Since ever in open urological surgery, the lateral retroperitoneal approach represents the typical way to approach this kind of surgery. Although different surgical approaches can be chosen (i.e., posterior retroperitoneal, lateral retroperitoneal, laparoscopic transperitoneal, and robotic approach), the lateral retroperitoneal approach represents the typical way to perform this kind of surgery, also with minimally invasive techniques. In this article, we illustrate the technique of retroperitoneoscopic nephroureterectomy in infants and children, reporting our experience with this technique in the past 20 years.
