Bilateral Renal Parenchymal Disease

12/30/2008

Question:

My brother has been dignosed as having Bilateral Renal Parenchymal Disease 15 days ago. My lower abdomen Ultrasonography suggests that I also have Bilateral Renal Parenchymal Disease. I have a few questions: What does it mean? Is it curable? How should I keep my lifestyle to get rid of this disease? How is it treated and what is the prognosis? Will we be cured?

Answer:

The term "bilateral renal parenchymal disease" is a radiologic diagnosis, based on the appearance of the kidneys by ultrasound.  It simply means that both ("bilateral") kidneys appear more dense than normal, which generally means that scar tissue has replaced normal kidney tissue (also known as "parenchyma").  Kidney scarring can be caused by any of a number of kidney diseases, some of which are inherited, and some of which run in families (but are not directly inherited).  You and your brother both need to see a nephrologist (kidney specialist), who can do a thorough medical history and physical exam and order the appropriate blood, urine, and imaging tests to determine what disease you have (although it may not be the same one), what the course of the disease is likely to be, and what treatment is needed.  Please ask your family doctor to refer you as soon as possible; it is important to determine what the disease is, so that you can do what is needed to preserve the kidney function that you have.
