Well, I was going to look up and paste documents concerning health problems like cancer, fibroids, whatever but it turns out that no longer being suitable for life due to damage is a valid reason for a hysterectomy, according to the Holy See.

Response to a question
on the liceity of a hysterectomy in certain cases
On July 31, 1993, the Congregation for the Doctrine of the faith published
Responses to Questions Proposed Concerning “Uterine Isolation” and Related Matters . These responses, which retain all of their validity, consider the removal of the uterus to be morally licit when there is a grave and present danger to the life or health of the mother, and hold as illicit, insofar as they are methods of direct sterilization, the removal of the uterus and tubal ligation (
uterine isolation ) with the intention of making impossible an eventual pregnancy which can pose some risk for the mother.
In recent years some very specific cases have been submitted to the Holy See also concerning the hysterectomy, which, however, present a different issue from that which was examined in 1993, because they regard situations in which procreation is no longer possible. The question and the response, accompanied by an Illustrative Note, that are now being published refer to this new particular case and complete the responses given in 1993.
Question : When the uterus is found to be irreversibly in such a state that it is no longer suitable for procreation and medical experts have reached the certainty that an eventual pregnancy will bring about a spontaneous abortion before the fetus is able to arrive at a viable state, is it licit to remove it (
hysterectomy )?
Response : Yes, because it does not regard sterilization.
