Did ourans die from casterration

It seems there might be a typo in your question. If you're referring to "Uranus," in mythology, he was castrated by his son Cronus. However, if you're asking about "dourans" or another term, please clarify. In general, castration can lead to death if it results in severe complications or infection, but it is not typically a direct cause of death in most historical or mythological contexts.
