Testicular necrosis secondary to incarcerated inguinal hernia in male infants. Own observations.

One of the possible consequences of incarcerated inguinal hernia in boys is testicular ischemia because of the prolonged compression of spermatic cord structures by the sac contents, resulting in ipsilateral testicular atrophy. This complication is well described in the literature and occurs in 5-34% of patients. The incidence of testicular atrophy secondary to incarcerated hernia is estimated to be 2-3%. Testicular necrosis as the result of hernia incarceration is, however, an extremely rare clinical setting. We present 4 male infants aged 3-10 weeks with inguinal hernia incarceration which led to ipsilateral testicular loss. All the boys had to be operated on because of irreducible incarcerated hernia and in all the cases testicular necrosis was found intraoperatively. The time of incarceration before surgical intervention ranged from 4 to 12 hours (mean 6.75). Our data show that every case of hernia incarceration in a very young male infant requires rapid diagnosis and proper intervention, i.e. surgical treatment, instead of repeated attempts of manual reduction. Ultrasound examination should estimate not only blood flow through the incarcerated intestinal loop, but also through the ipsilateral testis. Moreover, during the operation of the incarcerated hernia in a boy it is necessary to estimate the ipsilateral testis.
