Testicular torsion, also known as spermatic cord torsion, is the main cause of acute testicular pain in adolescents. If the testicle is compared to a watermelon, the spermatic cord is the vine, so the vine supplies nutrients to the watermelon. “If the “vine” is twisted, that is, it turns around, then the “watermelon” will be necrotic because of the loss of nutrient supply. Therefore, testicular torsion is the acute ischemia and necrosis of the testicle caused by the sudden obstruction of the blood supply to the testicle due to the rotation of the spermatic cord. Testicular torsion is a urological emergency, and the symptoms it causes are mainly acute pain in the testicle, which is initially vague and soon becomes severe and continuous, and can radiate to the ipsilateral lower abdomen, and may be accompanied by nausea and vomiting. The most serious danger of testicular torsion is that it leads to necrosis of the diseased testicle, in addition to the possibility of affecting the spermatogenic function of the testicle and thus leading to infertility, as well as the psychological impact on the patient after the necrosis of the testicle is removed. It can be said that this disease is a “teenager killer”. In fact, the clinical diagnosis of this disease is not very difficult, color ultrasound is the most simple and fast diagnosis method, then why the success rate of rescue of the lesioned testicles has been very low, there are two reasons: 1, the child and parents do not pay enough attention to the pain of the child’s testicles, ashamed to say, until the pain is unbearable to say to parents, and parents find this situation, the first reaction is often The first reaction of parents who find this situation is often “inflammation”, take the child to the clinic to play “anti-inflammatory injection”, the symptoms continue to be unable to improve, only to remember to take the child to a large hospital for consultation. 2, in addition to professional urologists and male surgeons, many clinic doctors do not know much about this disease, and often think it is “acute orchitis”, thus delaying the time of consultation. After the occurrence of testicular torsion, 4-6 hours is the best time to surgically reset, within this time, the testicular salvage rate can reach more than 90%, the longer the delay, the worse the relative effect, more than 24 hours, basically ischemia, necrosis end. If your child has acute scrotal and testicular pain, it is important that you go to the urology department of a regular hospital in a timely manner. Care for boys and prevent testicular torsion!
