The  treatment depends on the cause of the urine leakage. I advise you to visit a urologist in person first. Based on some evaluations, the cause of the problem can be known and accordingly the doctor may decide whether your mother needs surgery or medications. 

It looks like you have a vaginal infection. The­ swelling and yellow discharge are­ common signs. Infections can happen because­ of too many bacteria or yeast.
