What is complicated pyelonephritis?
Complicated UTI and pyelonephritis are infections of the urinary tract that occur in a wide spectrum of patients. Complicated UTI should be suspected when there are anatomical or functional abnormalities predisposing to infection or infection caused by multidrug resistant bacteria making treatment more difficult.

What is the difference between complicated and uncomplicated UTI?
Uncomplicated cystitis refers to lower urinary tract infection (UTI) in either men or non-pregnant women who are otherwise healthy. Complicated cystitis, on the other hand, is associated with risk factors that increase the virulence of the infection or the potential of failing antibiotic therapy.
What is the difference between a UTI and pyelonephritis?
A urinary tract infection is inflammation of the bladder and/or the kidneys almost always caused by bacteria that moves up the urethra and into the bladder. If the bacteria stay in the bladder, this is a bladder infection. If the bacteria go up to the kidneys, it is called a kidney infection or pyelonephritis.
Is pyelonephritis considered complicated UTI?

1. What is pyelonephritis?
Pyelonephritis usually begins with inflammation of the ureters and bladder that spreads to the kidneys, usually by bacteria. Most cases of bacteria invade upstream from the lower urinary tract, such as in pregnant women with urine reflux phenomenon, bacteria will go upstream of urine to reach the renal pelvis and cause parenchymal damage. kidney.

What are the complications of acute pyelonephritis?
Acute pyelonephritis can have several complications such as renal or perinephric abscess formation, sepsis, renal vein thrombosis, papillary necrosis, or acute renal failure, with one of the more serious complications being emphysematous pyelonephritis (EPN).[4] Emphysematous pyelonephritis is a necrotizing infection of the kidney usually caused by E. colior Klebsiella pneumoniae and is a severe complication of acute pyelonephritis. EPN is usually seen in the setting of diabetes and occurs more frequently in women. The diagnosis can be made with ultrasound, but CT is typically necessary. Overall the mortality rate is estimated to be approximately 38% with better outcomes associated with patients who receive both medical and surgical management versus medical management alone. [5]
What is the most common bacterial infection that causes pyelonephritis?
E. coliis the most common bacteria causing acute pyelonephritis due to its unique ability to adhere to and colonize the urinary tract and kidneys. E.colihas adhesive molecules called P-fimbriae which interact with receptors on the surface of uroepithelial cells. Kidneys infected with E. colican lead to an acute inflammatory response which can cause scarring of the renal parenchyma. Though the mechanism in which renal scarring occurs is still poorly understood, it has been hypothesized that the adhesion of bacteria to the renal cells disrupts the protective barriers, which lead to localized infection, hypoxia, ischemia, and clotting in an attempt to contain the infection. Inflammatory cytokines, bacterial toxins, and other reactive processes further lead to complete pyelonephritis and in many cases systemic symptoms of sepsis and shock.
How to diagnose acute pyelonephritis?
A good history and physical is the mainstay of evaluating acute pyelonephritis, but laboratory and imaging studies can be helpful. A urinary specimen should be obtained for a urinalysis. On urinalysis, one should look for pyuria as it the most common finding in patients with acute pyelonephritis. Nitrite production will indicate that the causative bacteria is E.coli. Proteinuria and microscopic hematuria may be present as well on urinalysis. If hematuria is present, then other causes may be considered such as kidney stones. All patients with suspected acute pyelonephritis should also have urine cultures sent for proper antibiotic management. Blood work such as a complete blood cell count (CBC) is sent to look for an elevation in white blood cells. The complete metabolic panel can be used to search for aberrations in creatinine and BUN to assess kidney function. The imagining study of choice for acute pyelonephritis is abdominal/pelvic CT with contrast. Imaging studies will usually not be required for the diagnosis of acute pyelonephritis but are indicated for patients with a renal transplant, patients in septic shock, those patients with poorly controlled diabetes, complicated UTIs, immunocompromised patients, or those with toxicity persisting for longer than 72 hours. Ultrasonography can be used to detect pyelonephritis, but a negative study does not exclude acute pyelonephritis. Regardless, ultrasound can still be a useful study when evaluating for acute pyelonephritis because it can be done bedside, has no radiation exposure and may reveal renal abnormalities, which can prompt further testing or definitive treatment.
What is the most common disease of the kidneys?
Acute pyelonephritis is a bacterial infection causing inflammation of the kidneys and is one of the most common diseases of the kidney. Pyelonephritis occurs as a complication of an ascending urinary tract infection (UTI) which spreads from the bladder to the kidneys and their collecting systems. Symptoms usually include fever, flank pain, nausea, vomiting, burning on urination, increased frequency, and urgency. The 2 most common symptoms are usually fever and flank pain. Acute pyelonephritis can be divided into uncomplicated and complicated. Complicated pyelonephritis includes pregnant patients, patients with uncontrolled diabetes, kidney transplants, urinary anatomical abnormalities, acute or chronic kidney failure, as well as immunocompromised patients and those with hospital-acquired bacterial infections. It is important to make a distinction between complicated and uncomplicated pyelonephritis, as patient management and disposition depend on it.
What is the bacterial infection that causes a burning sensation in the kidneys?
Acute pyelonephritis is a bacterial infection causing inflammation of the kidneys.

Symptoms usually include fever, flank pain, nausea, vomiting, burning with urination, increased frequency, and urgency. This activity outlines the clinical presentation, diagnosis, and management of acute pyelonephritis , and highlights the role of the interprofessional team in caring for patient with the condition.
How is pyelonephritis treated?
Overall the majority of cases of pyelonephritis are managed in an outpatient setting with most patients improving with oral antibiotics. Usually, young women are among those most likely to be treated as outpatients.[1] Despite pyelonephritis improving in most cases, there is still significant morbidity and mortality that can be associated with severe cases of this disease. Overall mortality has been reported around 10% to 20% in some studies with a recent study from Hong Kong finding a mortality rate closer to 7.4%. More importantly, this study found that old age (older than 65 years), male gender, impaired renal function, or presence of disseminated intravascular coagulation were associated with increased mortality. With the proper recognition of the underlying etiology and prompt intervention with adequate treatment, even patients with severe pyelonephritis generally have a good outcome. [3]
When diagnosing acute pyelonephritis, keeping the differential broad is a wise idea?
When diagnosing acute pyelonephritis, keeping the differential broad is a wise idea. Physicians should consider other disorders as well when patients present with fever, flank pain, and costovertebral angle tenderness. Because symptoms can be variable (unilateral, bilateral, radiating, sharp, dull) and because pyelonephritis can progress to sepsis and shock the differential diagnoses associated with pyelonephritis can be extensive. Common mimics of acute pyelonephritis can include but is not limited to:
