Kidney Biopsy

An overview of Kidney Biopsy

A kidney biopsy is a medical procedure that involves removing a small piece of kidney tissue for examination under a microscope. This test is typically performed to diagnose suspected kidney problems, assess the severity of a kidney condition, monitor the progress of kidney disease treatment, or evaluate a non-functioning kidney transplant. The procedure is performed using a thin needle guided by an imaging device. The kidney tissue is then examined by a specialist to detect any abnormalities such as deposits, scarring, infection, or other issues. Results are usually available within a week and the procedure is typically conducted at a hospital or outpatient center.

What is Kidney Biopsy used for?

A kidney biopsy is used to diagnose suspected kidney problems, develop treatment plans based on the kidney's condition, determine the progression of kidney disease, and monitor treatment effectiveness. It involves removing a small piece of kidney tissue for microscopic examination to identify signs of damage or disease. The procedure is performed by inserting a thin needle through the skin, guided by an imaging device, or through a small incision in the case of a laparoscopic biopsy. The tissue sample is sent to a specialized lab for examination by a pathologist. The results of the biopsy can help explain the cause of kidney problems or inform treatment plans.

How often should Kidney Biopsy be performed?

The frequency of kidney biopsy tests is not specified. Results may take up to a week to receive and can be used to plan or adjust treatment. The decision to perform a kidney biopsy is typically based on blood or urine tests, symptoms, and overall health.

How to prepare for Kidney Biopsy?

Before a kidney biopsy, patients need to stop taking medications and supplements that increase the risk of bleeding, such as blood thinners, platelet inhibitors, aspirin, ibuprofen, and certain dietary supplements. Patients should also avoid eating or drinking for eight hours before the procedure. It is important to bring a list of all medications, including over-the-counter medications, vitamins, and herbal supplements, to discuss with the doctor prior to the biopsy.

How is Kidney Biopsy conducted?

A kidney biopsy is usually performed by inserting a thin needle through the skin, guided by an imaging device such as an ultrasound probe or CT scan. The needle collects a small piece of kidney tissue for microscopic examination. The patient lies on their abdomen or side during the procedure, and the biopsy site is numbed with a local anesthetic. Multiple needle insertions may be necessary to obtain enough tissue. After the biopsy, the patient is monitored in a recovery room before being discharged.

Understanding the report

The interpretation of kidney biopsy results involves examining the kidney tissue under a microscope by a specialized pathologist. The pathologist looks for abnormalities such as deposits, scarring, infection, or other issues. The results can provide insights into the underlying cause of a kidney problem, determine the severity of a kidney condition, or guide treatment decisions for kidney disease. Results are typically available within a week, and your doctor will discuss the findings with you during a follow-up visit. If you experience concerning symptoms like significant blood in your urine, changes in urination, worsening pain, fever, or faintness, it's important to contact your doctor.
