Acute Pyelonephritis I: Introduction01:27

Acute Pyelonephritis I: Introduction

1.0K
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...

Acute Pyelonephritis II: Diagnostic Studies and Management

604
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...

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...

Urinary Tract Infection I: Introduction

947
Urinary tract infections (UTIs) impact various parts of the urinary system, including the kidneys, ureters, bladder, and urethra. These infections are generally bacterial, with Escherichia coli being the most common causative agent, often originating from the gastrointestinal tract. However, other bacteria, such as Staphylococcus saprophyticus, Klebsiella pneumoniae, and Proteus mirabilis, are also known to cause UTIs. The type, location, and underlying complexity of the UTI guide both...

Urinary Tract Infection II: Pathophysiology

1.0K
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...

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...

Area of Science:

  • Nephrology
  • Infectious Diseases
  • Urology

Background:

  • Encrusted uretero-pyelitis is a rare, severe condition characterized by pelvicalyceal and ureteral calcifications, frequently linked to chronic urinary tract infections.
  • Corynebacterium urealyticum is the predominant pathogen implicated in this infection-induced lithiasis.
  • Computed tomography (CT) scan findings of calcifications can aid in diagnosis, but delays are common.

Observation:

  • Accurate bacteriologic exploration is vital to prevent diagnostic delays.
  • A case study involved a 77-year-old male patient with bilateral encrusted uretero-pyelitis.

Findings:

  • The patient was successfully treated using a combination of local acidification with Thomas's solution and oral acidification with ammonium chloride.
  • This treatment regimen, involving urine acidification, aligns with established medical literature findings.

Implications:

  • This case highlights the effectiveness of urine acidification in managing encrusted uretero-pyelitis.
  • Prompt and accurate bacteriologic diagnosis is crucial for timely and effective therapeutic interventions.
  • The successful application of local and oral acidification offers a viable treatment strategy for this challenging condition.
