My mom has something similar. Except she started with a leaky bladder (after getting a hysterectomy) and had a bladder sling put in. Long story short she was one of the unlucky souls that received a faulty bladder sling which ultimately disintegrated and was absorbed into the walls of her bladder. She's had multiple surgeries to remove the damaged sling but they cannot get every single piece of it. So now she lives with almost constant UTI's, random sharp pains in her bladder and kidney stones. It has gotten so bad that the doctor has just written her a prescription for unlimited refills on an antibiotic when she gets a UTI.  And, the problem that the sling was supposed to resolve remains. She hardly ever leaves the house now but when she does she has to wear an adult diaper with her just in case.  I feel so fucking bad for her.
