Peritoneography, a safe method to assess the bilaterality of inguinal hernias in children with an obvious unilateral hernia or cryptorchidism (100 cases).

A safe method to assess the bilaterality of inguinal hernias by herniography in 100 children up to 13 years was successfully adopted for the young patients with already a clinical unilateral hernia or undescended testis. In 40% of the cases was an occult contralateral open processus vaginalis peritonei radiologically discovered and surgically removed during the anesthesia for primary inguinal pathology. This is a safe preventive and curative technique to treat inguinal hernias in infants and children.
