**Abstract**

With the worldwide increase in the incidence of atherosclerotic coronary artery disease, the rate of coronary interventions has increased. One of the serious complications of this procedure is contrast-induced nephropathy (CIN). This complication can lead to poor outcomes, with an increase in morbidity and mortality of patients. The pathophysiology and risk factors for the occurrence of contrast-induced nephropathy are several and interconnected. The most proposed management of this entity is prophylaxis and thus avoidance of its occurrence. We will take a deeper look on the pathophysiology, the mechanisms by which this complication is aggravated, and how to expect and manage such a problem.
