The condition characterized by renal infarction is ischemia of the renal tissue. Renal infarction occurs when there is an inadequate blood supply to the kidney, leading to tissue death. Ischemia refers to the lack of blood flow, which is a primary cause of infarction. Various underlying factors, such as embolism, thrombosis, or systemic hypotension, can disrupt blood supply to the renal arteries, resulting in ischemic damage.

In this context, renal infarction directly links to ischemic injury as the tissues lose oxygen and nutrients, which are essential for cellular survival. Without prompt restoration of blood flow, the affected kidney region can suffer irreversible damage. Understanding this process emphasizes the importance of maintaining adequate renal perfusion to prevent such complications.

The other conditions, while they may be related to kidney function or health in different contexts, do not directly reflect the scenario of renal infarction. Cancerous growth can lead to various complications but does not primarily cause ischemia unless it obstructs blood vessels. Anemia relates to a deficiency of red blood cells or hemoglobin and does not directly indicate kidney ischemia. Unilateral kidney development describes a congenital condition not inherently related to infarction or ischemia.
