<unk>  is a surgical emergency that requires immediate intervention to restore the flow of blood to the testicle. If treated either manually or surgically within six hours, there is a high chance (approximately 90%) of saving the testicle. At 12 hours the rate decreases to 50%; at 24 hours it drops to 10%, and after 24 hours the ability to save the testicle approaches 0, although salvage of the testicle has been reported beyond 24 hours. About 40% of cases result in loss of the testicle. With prompt diagnosis and treatment the testicle can often be saved. Typically, when a torsion takes place, the surface of the testicle has rotated towards the midline of the body. Non-surgical correction can sometimes be accomplished by manually rotating the testicle in the opposite direction (i.e., outward, towards the thigh); if this is initially unsuccessful, a forced manual rotation in the other direction may correct the problem. The success rate of manual detorsion is not known with confidence. When salvage of the testicle is accomplished, long-term testicular damage is common. Testicular size is often diminished, and injury to the unaffected testicle is common. The effect of a torsion event on long-term fertility is not fully understood. A repeat doppler ultrasound scan may confirm restoration of blood flow to the testicle following manual detorsion. However, surgical exploration is often performed in order to assess the health and viability of the testicle. An orchiopexy is performed to both the affected and unaffected testicles in order to prevent recurrence. If the testis is not viable, it is removed (orchiectomy).
