Abstract:
A newborn male presented at birth with findings consistent with bilateral testicular torsion. Preoperative ultrasound demonstrated no flow to either testicle, and he underwent surgery, during which bilateral extravaginal testicular torsion was confirmed. The right testicle was grossly necrotic and orchidectomy was performed, whereas the left testicle was indeterminate and underwent detorsion and orchidopexy. At 6-month follow-up, the left testicle remained within normal clinical limits with good flow on ultrasound examination.
