Summary
A rare case of acute pyelonephritis caused by bladder catheter obstruction of the ureter in a 93-year-old man was successfully treated. Prompt management involving catheter replacement and antibiotics restored kidney function.
Area of Science:
- Nephrology
- Urology
- Infectious Diseases
Background:
- Urinary tract infections (UTIs) are common in patients with indwelling catheters.
- Ureteral obstruction secondary to bladder catheterization is a rare but serious complication.
- Prompt diagnosis and management are crucial to prevent renal damage.
Observation:
- A 93-year-old male presented with fever and pyuria due to an indwelling catheter.
- Laboratory findings revealed hyperleukocytosis, inflammatory syndrome, and acute renal failure.
- Abdominal CT scan confirmed left ureteral obstruction by the catheter's distal tip, causing ureterohydronephrosis.
Findings:
- Successful treatment involved replacing the indwelling catheter with a three-way catheter for irrigation.
- Parenteral antibiotic therapy was administered.
- The patient experienced successful clinical and biological recovery, with preserved left upper urinary tract function.
Implications:
- This case highlights the importance of considering catheter-induced ureteral obstruction in patients with indwelling catheters and signs of upper UTI.
- Early recognition and intervention, including catheter repositioning and antibiotics, can prevent irreversible renal damage.
- Reviewing management strategies for such rare obstructions is essential for clinical practice.

1.5K
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...

1.4K
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...

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...

808
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...

The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...

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...
