Bilateral renal papillary necrosis due to Candida infection in a diabetic patient presenting as anuria.

A 38 years insulin-dependent diabetic male, with nephropathy on antituberculous treatment presented with painless frank hematuria followed by anuria for a day which was associated with fever. Ultrasonogram of the abdomen showed bilateral hydroureteronephrosis. Necrotic papillae were retrieved after ureteroscopy which on histopathological examination and culture showed Candida albicans. This was successfully treated with fluconazole and ureteroscopic removal of necrotic papillae.

Pielonefritis enfisematosa: revisión retrospectiva y análisis de la literatura / Imaging of emphysematous pyelonephritis and review of the literature

La pielonefritis enfisematosa es una infección rara, difusa, fulminante, necrosante, supurativa, con producción rápida de gas que se disemina a través de la vía sanguínea a otros órganos, complicación fatal de una pielonefritis aguda.Es casi exclusiva de pacientes diabéticos en edad avanzada o media y en ocasiones la PE se diagnostica antes que la diabetes.El diagnóstico debe establecerse radiológicamente y hoy el mejor método de imagen y el que la literatura mundial avala como la forma más otil y práctica es la tomografía computada. El objeto de este artículo es analizar los signos radiológicos más comunes con base en imágenes obtenidas en nuestro servicio.

Later complications on diabetic patients: nephropathies in necropsy material

The purpose of the present study was to analyze in detail the kidney lesions of diabetic patients. Revision of the histopathologic aspects of this nephropathy was performed, seeking to approach the pathophysiology of its formation. In 200 consecutive necropsies of cadavers of diabetic patients examined at the Pathology Department of the Medical School of the Säo Paulo University, some degree of nephropathy was found in 158 cases. The slides from parffin sections of these cases were reviewed according to a morphologic protocol previously established. Diffuse, nodular and mixed glomerulosclerosis were encountered in 42.2 per cent, 21.5 per cent and 5.7 per cent respectively. Subvcapsular drop and exudative lesion appeared in 12,7 per cent and 15.2 per cent of the cases. We also encoutered arteriosclerosis in 81.6 per cent, arteriolosclerosis in 88.6 per cent, necrotizing papillitis in 11.4 per cent and acute and chronic pyelonephritis in 23.4 per cent and 20.9 per cent respectively. We concluded that glomerular and vascular hyalin alterations were the most frequent findings in diabetic patients
