Answer to Question 1

Avascular necrosis

Answer to Question 2

Ureters enter the bladder at an angle such that as the bladder contracts, the muscles of the bladder compress the ureters like a one-way valve. Second, the ureteral openings in the bladder are partially covered by folds of mucosa that also help prevent the retrograde flow of urine.
