Uroradiology of diabetes mellitus.

Diabetes mellitus is a prevalent disorder, well controlled in many persons with prolongation of life. Several radiologic manifestations are sufficiently specific to suggest a diagnosis in the unidentified patient, but even more important is an awareness of the sometimes life-threatening complications of diabetes which can be diagnosed from uroradiologic studies. We review the following urinary tract manifestations and complications of diabetes: pyelonephritis, perinephric abscess, renal papillary necrosis, emphysematous pyelonephritis, emphysematous cystitis, fungus infections, calcification of the vas deferens, seminal vesicle, and intrarenal branches of the renal artery, neuropathic bladder, and renal failure.
