What are the complications of acute pyelonephritis

First, renal abscess and perirenal abscess. Hematogenous pyelonephritis is a local manifestation of systemic bacteremia or sepsis. Hematogenous pathogens spread to the renal interstitium and form a small abscess. If not treated in time, the small abscess will fuse and develop into a larger abscess. If the abscess penetrates the renal parenchyma, it can form perirenal abscess. If the abscess expands and destroys the whole kidney, it will become pyonephrosis. In addition to the symptoms of systemic sepsis, such as shivering, high fever and general discomfort, the patient had distending pain in the renal area and aggravated pain during palpation. If accompanied by urinary tract obstruction, the disease progressed faster.

Second: sepsis. Acute pyelonephritis complicated with urinary tract obstruction, when the urine flow is not smooth, the pathogens in the kidney can often spread into the blood circulation and form sepsis, which is called urinary tract sepsis, or exactly nephrogenic sepsis. Most of them are caused by gram-negative bacilli, and their condition is serious. More than half of them have shock, which leads to acute renal failure.

Third: acute renal failure. Simple acute pyelonephritis complicated with acute renal failure is caused by blood borne infection. The pathogen is mostly Staphylococcus aureus, which is the local manifestation of systemic bacteremia or sepsis. In fact, it is a complication of acute sepsis. Septic shock or acute hypovolemia and the role of endotoxin can lead to acute renal failure.
