Physiological changes in transperitoneal versus retroperitoneal laparoscopy in children: a prospective analysis.

Purpose: The choice of minimally invasive surgical approaches in pediatric urology is largely influenced by surgeon preference and experience. Little is known about the differences in physiological variables that might objectively influence the choice of surgical approach. We compared the cerebral and systemic hemodynamic effects of transperitoneal vs retroperitoneal CO(2) insufflation in children.
