What Is Bilateral Parenchymal Renal Disease?

Bilateral renal parenchymal is a disease in which kidney tissue, or parenchyma, has generally been replaced by scar tissue, explains Net Wellness. The diagnosis is based on ultrasound results. If kidneys appear more dense than normal, then bilateral renal parenchymal disease is said to be present.

There are many kidney diseases than can cause scarring. Some are inherited, while others, though not directly inherited, seem to present in families. The exact kidney disorder responsible for one's parenchymal disease is determined through appropriate imaging and blood and urine tests, as well as a thorough physical exam and medical history. These investigations should be requisitioned and interpreted by a kidney specialist. A referral to a nephrologist comes from a general practitioner. It is important to determine the cause of kidney damage, in order to choose the most effective treatment regimen, points out HealthTap.

Some common signs of problems with kidney function include high blood pressure, edema, swelling of the lower legs or feet, and urinary tract infection symptoms, says Net Wellness. While some underlying conditions causing renal parenchymal disease may be treated, others may not, notes HealthTap. In the case of progressive illness, a transplant or a lifetime of dialysis may be necessary.
