INTRODUCCIÓN: Aunque la fístula renocólica es una complicación conocida de la forma difusa de la pielonefritis xantogranulomatosa, describimos un caso inusual, por la pobreza de los síntomas y la larga evolución de la enfermedad antes de ser diagnosticada. CASO CLÍNICO: Una mujer de 75 años fue vista en el Servicio de Urgencias con fiebre y malestar general. El examen y las pruebas de laboratorio mostraron una masa en el hemiabdomen izquierdo y anemia, y en la radiografía de abdomen y la tomografía computarizada se encontró un cálculo grande así como una gruesa pielonefritis xantogranulomatosa con fístula renocólica. Una revisión de su historial médico mostró una radiografía de abdomen realizada más de dos años antes por su médico de familia, con el mismo cálculo y gas en la cavidad renal. Se le realizó nefrectomía, pancreatectomía caudal y colectomía parcial con buenos resultados. COMENTARIO: La pielonefritis xantogranulomatosa es una forma infrecuente de infección crónica del riñón y de los espacios retroperitoneales. Este caso poco sintomático que destruyó el riñón e indujo una fístula renocólica, es inusual porque pasó inadvertido durante años a pesar de una manifestación clínica y radiológica bastante típica.
INTRODUCTION: Although reno-colic fistula is a well-known complication of the diffuse form of xanthogranulomatous pyelonephritis, the features of the case here presented are unusual because of the paucity of symptoms and long lasting evolution of the disease before it was diagnosed. CLINICAL CASE: A 75 year-old woman was seen at the emergency room complaining of fever and malaise. Physical and laboratory examination showed anemia and a left abdominal mass, and on X-ray and abdominal CT, a gross stone and huge left renal and extrarenal xanthogranulomatous pyelonephritis with renocolic fistula were disclosed. A review of her clinical record showed an X-ray performed two years before by the attending family clinician, with identical gross calculi and gas into the kidney. Nephrectomy, caudal pancreatectomy and partial colectomy were accomplished with good results. COMMENT: This case of poor-symptomatic xanthogranulomatous pyelonephritis that destroyed the kidney and induced a renocolic fistula, is unusual because it was neglected for more than two years due to unawareness of the clinical and radiological picture.
