Renal malacoplakia with papillary necrosis and renal failure

Renal parenchymal malacoplakia is a rare cause of renal failure. Patients presenting with renal failure carry a poor prognosis, the majority either dying or requiring chronic dialysis. In this report, we describe an alcoholic man who presented with renal failure due to bilateral renal parenchymal malacoplakia and papillary necrosis. The patient, who initially required dialysis, partially recovered renal function following prolonged antibiotic treatment with a fluoroquinolone antibiotic.
