Renal Biopsy Treatments
A renal biopsy procedure is the removal of a small piece of kidney tissue to be examined in the laboratory. An unexplained drop in kidney function or persistent blood in the urine or protein in the urine are all common reasons for a renal biopsy. The test is sometimes used to evaluate a transplanted kidney.
Renal Biopsy Procedure by Ultrasound Guidance
- There are many ways to perform a renal biopsy procedure. The most common uses ultrasound guidance. This means the doctor uses an ultrasound image to locate the proper area in the kidney. The renal biopsy procedure is done in the hospital, usually in the radiology suite.
- The patient lies face down for a minimum of 20 to 30 minutes. Ultrasound is used to find the proper biopsy site. The health care provider then injects a local anesthetic under the skin, makes a tiny cut and inserts a biopsy needle. Multiple needle insertions may be needed in order to collect enough tissue for a successful renal biopsy.
After the renal biopsy procedure, the patient stays in bed for six to eight hours and remains in the hospital for at least 12 hours. Pain medicines and fluids are given as needed. Urine is checked for excessive bleeding, and blood counts and vital signs are monitored.
Other Renal Biopsy Procedures
Renal Biopsy by CT Scan Guidance
Transjugular Renal Biopsy. In this method, the biopsy catheter is run through one of the neck veins.
Surgical Renal Biopsy. Although surgical biopsies have traditionally required a three- to five-inch cut, they can often be done laparoscopically, which usually results in smaller surgical cuts. A surgical biopsy involve a longer recovery period than a simpler, needle biopsy.
