Can we preserve the necrotic testis caused by incarcerated inguinal hernia in infants under 3months?

Abstract

This study aims to investigate whether necrotic testis resulting from incarcerated inguinal hernias can be preserved in infants under 3months old. A retrospective analysis was conducted on data collected from infants under 3months old who had necrotic testis caused by incarcerated inguinal hernias between 2016 and 2020. They were divided into two groups: the orchiectomy group and the testicular preservation group. The control group consisted of normal male children of the same age. Data regarding bilateral testicular volume, dihydrotestosterone, inhibin B, and antisperm antibodies were collected. The study included 42 cases, with 18 patients being followed up for 6-54months after the operation. In the testicular preservation group, 2 children did not experience testicular atrophy. There was no significant difference in the volume of the contralateral testes between the testicular preservation group and the control group; however, both groups had smaller testicular volumes compared to the orchiectomy group. There was no significant difference in the levels of inhibin B between the testicular preservation group and the orchiectomy group, although both were lower than the control group. Furthermore, no significant difference was observed in the levels of dihydrotestosterone and the positivity rate of antisperm antibodies among the three groups. Preserving the necrotic testis may allow it to survive without impacting the contralateral testis. Therefore, a more conservative approach should be considered for orchiectomy when dealing with testicular necrosis caused by incarcerated inguinal hernias in infants.
