Testicular torsion is a urological emergency that tends to occur in adolescents with nocturnal onset. Once the testicle is torsioned, the duration of pain is mainly based on the degree of testicular torsion. In severe cases of testicular torsion, the pain lasts for 12 hours, but for more than 12 hours, the ischemic and hypoxic lesions caused by testicular torsion and the testicular necrosis are irreversible. Therefore, with prolonged testicular torsion, the patient will lose pain sensitivity. However, the above situation is a process that suggests that testicular torsion causes aggravation of the disease, so clinically, patients with testicular torsion should be promptly repositioned by manipulation. If the manipulation fails and there is persistent pain, there is usually still some time to save. In this case, you should go to the hospital for ultrasound examination in time, and after the testicular torsion is clearly identified, you can undergo surgery, during which the testicle is reset by manipulation and fixed on the meatus, which can be restored to normal.
