Op, the two may or may not be related, but anyone who throws a book at their 9 yo daughter has some serious issues.
Let me put this into context as I see it. My father threw tennis rackets, books, magazines and toys at me. Nothing to worry about you might say? No!!! He als beat my brother and mother senseless.
I had recurrent UTIs, not through sexual abuse but through a kidney condition. I also wet the bed regularly as a child, as I lay awake listening to my parents arguing and fighting.
Things aren't always black and white, not always clear cut. The two things may or may not be related, either psychologically, physically or sexually.
Get some help op, you have suspicions.
I really hope this is not trolling. Many mnetters, myself included, are here for you if you need help.
