Abstract
To highlight the ultrasonographic features of prenatal torsion of the testis in utero (IUTT) at presentation, the neonatal management and the histological findings postorchiectomy or biopsy. Seven newborns underwent emergency exploration for IUTT. All patients underwent a sonography and real-time color Doppler ultrasound study of the scrotum before any surgical procedure. A histological examination was performed in the removed specimens. Sonography of the scrotum revealed enlarged, heterogeneous testes. In all cases the color and power Doppler did not reveal any flow signal on the affected side. Four newborn with unilateral testicular torsion underwent orchiectomy and contralateral orchidopexy. In one neonate after detorsion and with the absence of gangrenous changes and a reassuring biopsy, a twisted testis could be treated conservatively with orchidopexy. In another case, the parents, acknowledging the inviability of the affected testis, gave consent only for a biopsy of the testis. In the neonate with bilateral IUTT, bilateral testicular biopsies were performed. Histology of the removed testes variably showed interstitial red cell extravasion and coagulation or hemorrhagic necrosis. Light microscopy of the preserved testis highlighted surviving seminiferous tubules, with gonocytes, spermatogonia and fetal Sertoli cells. An early diagnosis and treatment in IUTT is essential. Surgical exploration should be always performed through the inguinal route. In bilateral IUTT testes should be left to try to assure, as long as possible, a residual Leydig cell function.Keywords
