Summary
Emphysematous pyelonephritis (EP) is a severe kidney infection. Point-of-care ultrasound (POCUS) can rapidly diagnose EP and related complications, improving patient outcomes in resource-limited settings.
Area of Science:
- Nephrology
- Infectious Diseases
- Radiology
Background:
- Emphysematous pyelonephritis (EP) is a severe, life-threatening complication of acute pyelonephritis.
- Diagnosis is challenging due to overlapping symptoms with severe acute pyelonephritis.
- Computed tomography (CT) is the gold standard but often inaccessible in resource-limited areas.
Observation:
- Point-of-care ultrasound (POCUS) provides a rapid and accessible alternative for diagnosing complicated pyelonephritis.
- Renal POCUS can identify signs of EP and obstructive pyelonephritis.
- Case examples from Lima, Peru, demonstrate POCUS's utility.
Findings:
- POCUS effectively screens and risk-stratifies patients with severe acute pyelonephritis.
- It facilitates timely diagnosis and management of EP.
- POCUS optimizes CT utilization by identifying cases requiring further imaging.
Implications:
- POCUS can significantly improve the diagnosis and management of EP in resource-constrained settings.
- Early POCUS implementation can reduce morbidity and mortality associated with EP.
- This approach enhances patient care by enabling quicker interventions.

47
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

01:27Acute Pyelonephritis I: Introduction
65
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.

01:25Urinary Tract Infection II: Pathophysiology
52
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
