    Abstract:
    Among the causes of acute surgical abdomen, infection of a urachal remnant may go unnoticed despite routine complementary studies. We present three cases in boys aged 11, 6, and 4 years who were brought to the emergency department for right iliac fossa pain, fever, and urinary symptoms. Examination and complementary tests results were compatible with acute complicated appendicitis and were sent to surgery. While in the operating room, appendicitis was excluded and inflammatory changes suggestive of infection of the urachal remnant were documented. Complications of urachal remnants should be considered in the differential diagnosis of acute surgical abdomen, since advanced infection of the urachus may be a cause of confusion. A more accurate presumptive diagnosis can change the therapeutic/surgical approach and follow-up. Dentro de las causas de abdomen agudo quirúrgico, la infección de un remanente uracal puede pasar desapercibida en cuadros evolucionados a pesar de las pruebas complemetarias habituales. Presentamos tres casos de varones de 11, 6 y 4 años llevados a urgencias por dolor en fosa iliaca derecha, fiebre y síntomas urinarios. La exploración y las pruebas complementarias eran compatibles con patología apendicular aguda evolucionada y fueron intervenidos con dicha sospecha. En el quirófano se descartó apendicitis y se documentaron cambios inflamatorios sugestivos de infección de remanente uracal. Las complicaciones de los remanentes uracales deben ser tenidas en cuenta en el diagnóstico diferencial del abdomen agudo quirúrgico, ya que la infección evolucionada de estos puede confundirnos. Un diagnóstico de presunción más certero puede cambiar nuestra actitud terapéutica, quirúrgica y el seguimiento.
