Symptoms of Renal Parenchymal Disease

Renal parenchymal disease is non-specific and refers to abnormalities of the body of the kidney. There are multiple causes, including high blood pressure, drug toxicity and trauma.
The key to treatment is first to understand the potential causes and reverse as many of these as possible.
Depending on the severity of the illness and in general, avoidance of medications that can cause kidney injury is prudent. Several of these are commonly prescribed, including non-steroidal antiinflammatory medications, trimethoprim-sulfa and certain antiretroviral medications.
Kidney stones are very common, and when they pass the pain can be very severe. Stone formation can be either an inherited problem or because of an obstruction or a severe kidney infection. Kidney stones can also cause scarring and damage to the kidneys if not properly treated, however kidney stones can be managed successfully with early detection.
Diabetes is another medical condition that can lead to kidney disease. Certain medications such as chemotherapy medications, pesticides and illegal drugs can also cause severe damage the kidneys and kidney tissues.
Polycystic renal disease is hereditary type of kidney disease and starts in childhood and follows through adulthood. Other hereditary kidney diseases include Alport's syndrome and cystinuria.

Frequent urination
Blood in the urine
