[Managing a failed kidney graft. Nephrectomy versus embolisation].

The early diagnosis of the graft intolerance syndrome or a subclinical state of chronic inflammation due to a failed kidney allograft, is one of the goals that the nephrologists must fulfill to take a series of measures directed to solve this situation. Fever, haematuria, local pain and/or tenderness are the main clinical criteria to make a diagnosis. However, oftenly there are not any clinical symptoms and only the presence of parameters of chronic inflammation (elevated C-reactive protein, erythrocyte sedimentation rate, hypoalbuminemia and anemia resistant to erythropoietin therapy) are signs of this entity. Maintenance of immunosuppressive treatment is not advisable due to the risk of infections as well as the increase in cardiovascular risk (level evidence A). Transplantectomy is the best treatment if there are some associated complications such as allograft infection, neoplasia or high risk of graft rupture. However, surgical treatment is not exempt from risks and it is associated to a considerable rate of complications, with the consequent prolongation of the hospitalization stay. Therefore it is desirable to use less invasive procedures, such as embolization. This could be the first step unless the conditions enumerated in point 3 come up (Level evidence B). It is desirable to use prophylactic antibiotic before the embolization to avoid infectious complications (Level evidence B).
