A bad outcome doesn't always equal medical malpractice.

Your daughter could have had a ton of adhesions due to her endometriosis that could have plastered her colon and bladder walls to her uterus.

Damage to the bladder and ureters is a known complication of hysterectomies; damage to the colon, less so, but a risk.

Sounds like you had a pretty average gynecologist operate on your daughter, which isn't surprising because most OB-GYNs are average to terrible surgeons.

This is going to be hard case to prove malpractice on. Sorry this had to happen.
