[Torsion of undescended testis].

Torsion of a cryptorchidid testicle presents a non-specific symptomatology. Clinical suspicion indicates surgical exploration, irrespective of Doppler ultrasound with its inherent false negative results. With regards to treatment, an orchiectomy is performed when the testis is necrotic. Management of the contralateral testis is controversial. Our policy is not to fix them systematically because we believe that a healthy education of parents and children is more important, so as to obtain an earlier diagnosis of a future torsion.
