American Idol's Phillip Phillips Surgery Delayed

As we first reported, Phillip has a serious congenital kidney condition that produces kidney stones so large they cannot pass. The condition has virtually debilitated his right kidney -- requiring 8 prior surgeries.

Phillip has had a flare-up through almost the entire "American Idol" competition, requiring a stent that was surgically inserted two months ago -- causing the singer extreme and continuous pain.

We're told Phillip now has a bad sinus infection that has triggered a high fever. As a result surgeons will not operate.
