Kidneys play an important metabolic role and are essential for balancing salt, minerals and water in the body. They also play a significant role in removing waste products from the body. They make urine, which contains all the waste materials that are eliminated from the body. They also play an important role in blood pressure regulation and in maintaining the balance of various minerals in the body. Any suspected kidney damage should be confirmed by a kidney biopsy, which will reveal the exact disease, thereby directing towards the appropriate treatment.
Why and when is it done?
A renal or kidney biopsy is done in the following situations:
Know about the procedure
A renal biopsy is mostly done as an outpatient procedure and is a type of biopsy known as percutaneous biopsy (biopsy where a needle is inserted through the skin into the renal tissue). Very rarely, it may be combined with the CT scan or ultrasound and be done in the radiology department. This may be done on inpatients. The patient is made to lie on his/her back and a local anesthetic is used on the area of the injection. A thin, long needle is directed towards the area of the kidney from where some kidney tissue is removed for sampling.
In some cases, the direction of the needle may be decided by a CT scan or ultrasound. While this is a closed biopsy procedure, in some cases, as a part of the surgery, open biopsies may also be obtained, where a sample of tissue is extracted for analysis.
Recovering from a biopsy
The person would need some time to recover from the procedure, as there would be some discomfort at the site of a needle insertion. Vital signs would be monitored for the next couple of hours during which the person would also be monitored for internal bleeding. A pain reliever can be used if required. Haematuria or blood-tinged urine can be seen disappearing within the next 12 hours. Very rarely the bleeding can be severe and require angiography and further procedures. The person should also avoid strenuous activities for the next few days.

Sedentary lifestyle and unhealthy food habits result in many lifestyle diseases, coronary heart diseases being one among them. One of the top 10 leading causes of death, heart attack might scare you, and it is necessary to know the facts to avoid risk factors and seek the best treatment.
The coronary arteries supply blood to your heart muscle. But at times, they can become blocked owing to the buildup of cholesterol and other substances known as plaque. It can reduce the flow of blood to the heart. When the blood flow is entirely restricted, it may result in a heart attack.
Doctors typically recommend angiography during or after a heart attack or in the case of angina to find out about the condition of the heart and proceed accordingly. If any blockages are observed, angioplasty would be advised to improve the blood flow to the heart by widening the narrowed arteries. Read on to know further details regarding this.
What is coronary angiogram?
A coronary angiogram is a special X-ray test which helps in detecting if any of the coronary arteries are narrowed or blocked, hindering the optimal flow of blood. It can help your cardiologist understand whether you need any treatment such as stent or angioplasty or simple medical therapy.
During the process of angiography, your doctor would numb a spot in the arm or groin for inserting a thin catheter into the artery. You will get the feeling of a pinprick, and x-rays would be taken as the fluid goes through the coronary artery. After the process is completed, your doctor would discuss the results of the test with you and determine whether you need to undergo angioplasty.
