ABSTRACT
Acute scrotum is a common entity found in pediatric emergency rooms all over the world. This is a syndrome in which fast and accurate diagnosis is vital to perform an effective treatment of the underlying disease. Testicular torsion is the first diagnosis that has to be discarded. Torsion of appendix testis and epididymitis or orchitis must also be considered. If clinical signs are compatible with testicular torsion, and especially if the condition has not passed the six hours threshold, surgical exploration has to be perform at once. Radiological tests cannot delaysurgical exploration. Detorsion must be achieved as soon as possible to prevent irreversible ischemia and necrosis of the testicle that could lead to an orchiectomy. Once the torsion is relieved, the testicle must be placed in warm, moist sponges to test for adequate perfusion. If the testicle has acceptable blood supply, both testicles have to be fixed to prevent similar events in the future. If health providers are familiarized with the clinical presentation of these conditions, testicular torsion and other causes of acute scrotum could be diagnosed and treated rapidly and therefore important complications, such as fertility impairment, could be prevented.
