How We Can Help
Proteinuria & Hematuria Treatment Information
Proteinuria and hematuria are symptoms, rather than disorders. We find and treat their underlying causes. Techniques that we use include:
- Glomerular filtration rate (GFR) test. If there is protein in your urine, we check your kidney function with a test that estimates your glomerular filtration rate (GFR). Glomeruli are tiny structures in the kidneys that filter waste. This test tells us how well they are working. This test begins with a blood sample, which we analyze in a laboratory to determine your level of creatinine, a waste product that results from muscle movement and from protein in your diet. To determine your GFR, we look at the creatinine level alongside factors such as your age, gender and body size. GFR decreases with age.
- Cystoscopy. If there is blood in your urine, we may refer you to an IU Health urologist for a cystoscopy. This procedure involves looking for the cause of the blood using a cystoscope. This lighted, tube-like instrument, which is inserted through your urethra, allows a physician to see inside your bladder. Your physician may also take a biopsy or remove growths or bladder stones using tools that are guided through a tube (catheter). During the procedure, a physician fills your bladder with a sterile solution so that any lesions or growths are easier to see. The procedure lasts only a few minutes and is typically not painful. You may receive a local anesthetic or sedation.
- Imaging. We look for the reasons for protein in your urine using ultrasound. If you have blood in your urine, we may begin with intravenous pyelogram, a type of X-ray procedure that uses contrast dye to make the urine and any blockages visible. We then use techniques such as ultrasound or computed tomography (CT) to further investigate any masses.
- Kidney biopsy. A sample of your kidney tissue taken by needle or minor surgery can help us diagnose kidney problems that are causing proteinuria or hematuria. In the most common method, you lie on your stomach and we insert a needle into your back. You receive local anesthetic and light sedation before the procedure. We use ultrasound or another imaging technique, such as X-ray, to guide the needle to the correct place. It takes about 30 seconds to collect a tissue sample. We may need several samples. In some cases, we use another procedure to obtain the sample, depending on your condition and needs. For example, we may make an incision (cut) in your skin to obtain the kidney tissue. This procedure typically takes place under general anesthesia.
