There are many serious complication associated with pyelonephritis, but it is possible to prevent this disease by identifying and treating the various minor bladder infections .This is very useful as when you define pyelonephritis, you will learn that it is serious infection that may occur in the human kidneys.
To define pyelonephritis that is acute, one needs to consider the extent of infection. In acute cases the infection will be sever and affecting the interstitial area and renal pelvis. In advanced cases, where the infection is not treated on time, it may also spread to the renal tubules. On the other hand, if you want to define pyelonephritis that is chronic, it can be described as a persistent inflammation in the kidney tissues that retards the normal functioning and may even lead to kidney failure.
In fact, the chronic cases are a manifestation of recurring acute pyelonephritis events in the patient. The patient may also be showing other symptoms, like urinary obstructions or vesicoureteral reflux. There are many doctors who define pyelonephritis in a new perspective as they believe that the initial infection may occur elsewhere in the body and then the disease causing agent travels to the kidneys before causing pyelonephritis. The disease can be treated with the help of antibiotics, but the symptoms are also identified with chills, fevers and persistent fever in joints.
