"Pathology "
"Renal papillary necrosis is visible when excreted contrast material, e.g. at IVP, fills a necrotic cavity located centrally or peripherally in the papillae. Contrast-enhanced CT during the excretory phase can depict necrosis as clearly as does IV urography and thus allow accurate diagnosis of the condition 2."

"Patients can present with both acute episodes and chronic renal papillary necrosis. Calyceal or ureteral obstruction by sloughed papillae manifests with flank pain, haematuria and varying degrees of renal impairment. Anuria or oliguria may be present in the fulminant stage if renal failure develops. Urinary stasis leads to pyelonephritis with fever, chills or rigors."
