Usage notes
Precisely speaking, and  things are different from  and  things, because a  (a ) is different from a —it is a diminutive counterpart, as a blister on the skin, or an organelle inside a cell, is smaller than a urinary bladder or a gallbladder. This is why referring to intravesical chemotherapy as "intravesicular chemotherapy" is subtly misspoken; but the infelicity is subtle enough that no misunderstanding is likely and many readers will not think twice about the mischosen word. The same venial infelicity is true of meaning.
