It is understood by Chronic Renal Failure (CRF) or Stage IV Chronic Kidney Disease (CKD) the morbid state in which there is a substantial and irreversible loss of functional capacity, metabolic and endocrine function in both kidneys, leading to a framework of dehydration, azotemia, electrolyte imbalance, anemia, uremic syndrome, secondary hyperparathyroidism, among other conditions that make the patient's life without treatment unfeasible. An adequate nutritional support to patients with CKD at any stage aims to maintain a good clinical condition and an attempt to delay the progression of the disease. The basis of a diet for patients with CKD is the restriction in this protein being of high biological value, low-phosphorus, high energy density, fiber and antioxidants combined with a good dietary practices that allow the patient a good quality of life

The kidneys, for his anatomical and functional characteristics, are sensitive to affections that take the liberation of renal toxins or the blood supply, causing irreversible injuries to his renoparenchymal tissue that is substituted by fibrous tissue. Even after the resolution of the basic cause, there will be the loss of a significant number of his functional unity, renal adaptations will take place in the attempt of maintaining the renal function. These adaptations produce additional injuries, perpetuating to loss of renoparenchymal tissue and the reduction of the renal function. The renal insufficiency (IR) takes place after the loss of 3/4 of the number of his functional unities. Before the progression to the phase of IR, the animal shows up practically without symptoms, but for the gradual increase of the urinary and of the ingestion of water. The reduction of the degree of renal function leads to alterations system compensatory for the accumulation of substances that would suffer renal excretion. The progression of IR leads to the phase of the syndrome urêmica. In this phase the animal presents innumerable clinical signs that can take it to the death. The treatment is symptomatic and dietetic, but depending on the phase not much efficient. Because of being progressive and insidious, the IRC demands the preparation of campaigns and programs of explanation for the veterinary doctors who aim for the consciousness and/or sensibility of the owners to carry out periodic examinations of selection that precociously detect the renal dysfunction. The diagnosis in the beginning IR enables the efficiency of the treatment in stop or slowing his progression, extending the time and quality of life of the patient

Introducción: La insuficiencia renal aguda es una complicación frecuente en los pacientes cirróticos, existen varios estudios que señalan que el riesgo de insuficiencia renal aguda está significativamente aumentado en pacientes con hiperbilirrubinemia, hiponatremia y peritonitis bacteriana espontánea. La mayoría de los estudios se han centrado en la insuficiencia renal secundaria a la disfunción circulatoria que se denomina síndrome hepatorrenal; sin embargo que exisen otras causas, mucho más frecuentes en estos pacientes cuya posibilidad de prevención y corrección con tratamiento dirigido impone la pesquiza etiológica específica. Resultados: Durante el período analizado se registraron 18 episodios de insuficiencia renal aguda en 33 episodios de descompensación hepática crónica. La hipotensión por distintas causas y el uso de medios de contraste sin nefroprotección fueron los hechos más destacados. Discusión: la prevalencia de insuficiencia renal aguda fue superior a datos internacionales. Se analizan las distintas causas encontradas y su posible mecanismo etiopatogénico, así como medidas de prevención.
