Chronic Renal Failure (CRF) is the most common disease among dogs of any breed. It is the cause of high levels of morbidity and death rate in dogs. It's important to have an early diagnostic of the dogs condition and immediately start a supportive treatment for CRF. In this research we are discussing the most common types of treatment focused in reducing the progression of this disease and better quality of life for the animal with IRC

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

In recent years, uremic toxins have been widely investigated as an immunosuppressive factor for nephropathic patients. This study aimed to test the hypothesis that, as it was similarly observed in humans, the rate of apoptosis and superoxide production in polymorphonuclear leukocytes are changed in dogs treated with uremic serum. The superoxide production of polymorphonuclear leukocytes and apoptotic index of 10 healthy dogs incubated with autologous and homologous serum from healthy and uremic dogs was compared. Thus, there was an effect of partial inhibition of oxidative metabolism in uremia without correlation with the acceleration of polymorphonuclear leukocytes apoptosis in dogs.

Acute renal failure (ARF) may be defined as a subtle loss of renal function, leading to accumulation of nitrogenated substances. Several causes may lead to the development of ARF in an animal, including severe shock, intense blood loss, hypotension, dehydration, hypovolemia, deep anesthesia and nephrotoxins. Fluid therapy remains the basis of ARF treatment in animals. Thee therapeutic objective is to normalize fluid balance, solve hemodynamic problems and promote urine production. The objective of the present study is to review the procedures to manage acute renal failure in dogs and cats.

OBJETIVO: Avaliar a função renal de cães sadios, sob dois protocolos para administração de cisplatina. MÉTODOS: Todos os animais foram submetidos a três sessões de quimioterapia com cisplatina (60mg/m², iv) a intervalos de 21 dias. Foi realizada fluidoterapia com solução de cloreto de sódio a 0,9%, (25mL/kg/hora,iv), durante duas horas e, após administração de cisplatina, por mais uma hora. Os animais do grupo 2 receberam furosemida (2mg/kg, iv) 20 minutos antes da administração da cisplatina. A avaliação da função renal foi feita por exame clinico, urinálise, concentrações séricas de uréia e creatinina, clearance de creatinina, excreção fracionada de sódio e de potássio e razão proteína: creatinina urinária. As avaliações foram feitas imediatamente antes e 1, 2, 5, e 21 dias após cada uma das três sessões de quimioterapia. RESULTADOS: Mantiveram-se dentro da normalidade, não sendo detectados sinais de lesões ou insuficiência renal. Os animais que não receberam furosemida sofreram aumento gradativo nas concentrações séricas de creatinina e diminuição no clearance da mesma. CONCLUSÃO: O regime de fluidoterapia empregado mostra ser efetivo em minimizar a ação nefrotóxica da cisplatina e benefício adicional importante é obtido pela administração de furosemida.
