A kidney biopsy is often recommended for those who notice blood in the urine (hematuria), excess protein in the urine (proteinuria) or progressive kidney failure. Kidney biopsy might reveal the causes for improper functioning or rejection of a transplanted kidney. If urine tests, ultrasound or CT scan reveal possible kidney problems, kidney biopsy can aid in determining the cause.
A patient undergoing kidney biopsy is given sedation through IV. The biopsy needle is inserted through the skin with the aid of ultrasound. A small sample tissue is taken for examination. There is likely to be mild soreness in the muscle and some blood in the urine for the next 24 hours. Serious complications include puncture of a major blood vessel or bleeding into the kidney. Abnormal results of kidney biopsy show signs of scarring or inadequate blood flow or signs of disease such as renal cancer. Patients with blood clotting disorder are not advised to undergo this diagnostic test. Obesity, UTI, hypertension are some factors that can affect the accuracy of kidney biopsy results.
