Answer

Histology and/or imaging studies may help make the diagnosis of papillary necrosis. The sloughed papillae may be obtained by straining the urine and sending for histology. Retrograde pyelography is the radiologic procedure of choice, but ultrasonography or CT scan also reveals the diagnosis.
