Pediatric hernias and hydroceles. The urologist's perspective.

Pediatric inguinal hernias and hydroceles are due to incomplete or abnormal obliteration of the processus vaginalis. Surgical correction of these conditions is the most common surgical procedure performed on young children. The embryology, anatomy, evaluation, and management of pediatric inguinal hernias and hydroceles are reviewed. A thorough understanding of these topics will aid with the sometimes difficult decisions encountered in the care of these patients.
