Your Lasix renal scan report will show how well your kidneys filter waste from your blood. The report typically includes quantitative data such as the glomerular filtration rate (GFR) and differential renal function (DRF). Your doctor will use this information to diagnose and manage your kidney condition.
Understanding Key Measurements
- Glomerular Filtration Rate (GFR): This measures how much blood your kidneys filter each minute. A lower GFR indicates reduced kidney function. Normal values vary based on age and other factors, so your doctor will interpret this in context with your overall health. Differential Renal Function (DRF): This shows the percentage of blood filtered by each kidney individually. An imbalance suggests one kidney may be working harder or less efficiently than the other. Time-Activity Curves (TACs): These graphs illustrate how much contrast material your kidneys excrete over time. Abnormalities in these curves can pinpoint areas of obstruction or damage.
Your report will present these measurements numerically and visually, often with comparisons to expected ranges for someone of your age and health status. Expect to see images of your kidneys before and after the injection of Lasix.
What the Results Might Indicate
Normal results: Show symmetrical kidney function and normal GFR. This suggests both kidneys are working efficiently. Obstruction: A delay in excretion of contrast material might indicate a blockage in your urinary tract, such as a kidney stone or enlarged prostate. Kidney damage: Reduced GFR and asymmetrical function might suggest damage to one or both kidneys, possibly due to disease or injury. The location and extent of damage may also be determined. Reflux: Abnormal backflow of urine into the kidneys can be shown.
Remember, this interpretation is for informational purposes only. Always discuss your results with your doctor. They will consider your complete medical history and conduct a thorough examination to provide a proper diagnosis and recommend the best treatment.
Next Steps After Your Scan
- Schedule a follow-up appointment with your nephrologist or referring physician to discuss your results. Ask your doctor any questions you may have about your renal function and any necessary further steps. Be prepared to discuss your medical history, current medications, and any symptoms you are experiencing.
Further Information
Your doctor can provide additional information tailored to your specific case. They will explain the implications of your results and the next steps in your care.
