Varón de 53 años, con fiebre, disuria y lumbalgia. La tomografía mostró riñón derecho aumentado de tamaño, litiasis coraliforme (1300 UH), sistema colector dilatado, cambios inflamatorios con estriación de la grasa perirrenal, y colecciones con niveles hidroaéreos en las pirámides y en la pelvis renal (Figura 1). La pielonefritis enfisematosa es una infección grave, producida por bacterias formadoras de gas, es más frecuente en mujeres, el 90% de los casos se asocia a diabetes mellitus y con menor frecuencia a uropatia obstructiva. Frecuentemente es unilateral. La mortalidad es alta si compromete el espacio perirrenal; la tomografía el método más confiable y sensible.
