Take her to a Vet if possible. Rabbits pee does have an odor, are you smelling it or is the area red/infected. You've already bathed her but as balloonflower mentioned "spot cleaning" a good idea. If it's crusted, carefully clip away the fur for the area. Try & keep the area clean & dry. Taking her to a Vet, if the wound isn't too old, maybe able to stitch which would help alot preventing infection.
