Unless you plan to have IVF there is no reason to treat a hydrosalpinx.
The fluid within the tube, which is in connection with the uterus, can interfere with the embryos' ability to implant.
If this is not the case and it is not causing you any symptoms then I would leave well alone - surgery is likely to lead to further adhesions plus all the usual risks eg anaesthesia, pain, bleeding, infection, damage to other structures.
