renal infarction
Renal infarction refers to the death of a segment of the kidney tissue due to a lack of blood supply. It typically occurs when there is a sudden blockage in the renal artery or one of its branches, leading to inadequate blood flow to a portion of the kidney. Common causes of renal infarction include blood clot formation, atherosclerosis, or vasospasm.
Symptoms of renal infarction may include severe abdominal or flank pain, blood in the urine, fever, and decreased urine output. In some cases, the condition may be asymptomatic or present with nonspecific symptoms.
Diagnosis of renal infarction typically involves a combination of medical history, physical examination, laboratory tests (such as blood and urine tests), imaging studies (such as ultrasound, CT scan, or MRI), and sometimes, an angiography procedure to visualize the blood vessels in the kidney.
Treatment for renal infarction depends on the underlying cause and may involve anticoagulant medications to dissolve blood clots, thrombolytic therapy to restore blood flow, or surgical intervention in more severe cases. Managing the underlying cause, such as controlling blood pressure or addressing underlying heart conditions, is also important in preventing future episodes.
It is important to seek medical attention if one suspects renal infarction, as prompt treatment can help prevent complications such as kidney damage or the development of chronic kidney disease.
