Introduction

Pyelonephritis is divided into acute pyelonephritis and chronic pyelonephritis. Generally, most cases of acute pyelonephritis can be cured, whereas the cure rate for chronic pyelonephritis is lower. Acute pyelonephritis is an upper urinary tract infection with a higher incidence in females, and the majority of causative pathogens are Escherichia coli. It is usually caused by ascending infection via the urethra.

Acute pyelonephritis is an upper urinary tract infection with a higher incidence in women. The majority of causative pathogens are Escherichia coli, and most infections occur via ascending route through the urethra. Symptoms in patients with acute pyelonephritis mainly include chills, high fever, flank pain, as well as urgency, frequency, dysuria, and hematuria. Patients diagnosed with acute pyelonephritis should receive antimicrobial treatment under medical guidance, such as quinolones (e.g., levofloxacin capsules), semi-synthetic penicillins, and cephalosporins.

If acute pyelonephritis is not treated promptly during the early stage, or if the patient has underlying immune deficiency or low resistance, the condition may persist and progress to chronic pyelonephritis, which has a lower cure rate. Continued progression of chronic pyelonephritis may eventually lead to chronic renal failure.

In addition, infants and young children with acute pyelonephritis often have associated urinary tract malformations or functional disorders. Treatment decisions, including possible surgical intervention, should be made based on individual patient evaluation under physician guidance.

What bacteria cause pyelonephritis?

Pyelonephritis may be caused by Escherichia coli, alpha-hemolytic streptococcus, Klebsiella, Citrobacter, Streptococcus pneumoniae, etc. In addition, Staphylococcus aureus and Pseudomonas aeruginosa can also potentially cause pyelonephritis. If pyelonephritis occurs, patients may take medications such as cefixime capsules or minocycline hydrochloride capsules under the guidance of a physician.

Can pyelonephritis heal on its own?

Pyelonephritis generally does not resolve spontaneously and requires timely treatment. Pyelonephritis is classified into acute and chronic phases, with main symptoms including frequent urination, urgency, fever with chills, and headache. Chronic pyelonephritis may sometimes present only as asymptomatic bacteriuria; over half of the patients have a history of acute pyelonephritis and may experience mild fever and intermittent urinary frequency to varying degrees.

The most common pathogen causing pyelonephritis is

The most common pathogenic bacteria causing pyelonephritis are Gram-negative bacilli, Escherichia coli, Staphylococcus aureus, and other microorganisms. Gram-negative bacilli are commonly found as resident bacteria in the urinary system; normally retained locally in the urethra, they are readily flushed out by urine and thus unlikely to cause infection. However, when resistance is decreased, accompanied by reduced urine output and urine stasis in the local area, Gram-negative bacteria can easily proliferate.

The key to effective treatment of uncomplicated acute pyelonephritis is completing several days of therapy.

The key to effective treatment of uncomplicated acute pyelonephritis is completing a 14-day course of therapy. Uncomplicated acute pyelonephritis is an acute inflammatory condition caused by bacterial invasion of the renal pelvis, affecting one or both sides, and is a type of urinary tract infection. This condition is more commonly seen in women, as anatomical and physiological factors make women significantly more susceptible to urinary tract infections than men.
