Pelvocalyceal wall opacification--a new radiological sign

Area of Science:

• Radiology
• Urology
• Infectious Diseases

Background:

• Urinary tract infections (UTIs) are common, particularly when obstruction is present.
• Early detection of infection in obstructed systems is crucial for timely intervention.
• Current diagnostic methods may not always identify early-stage inflammatory changes.

Purpose of the Study:

• To describe a new radiological sign associated with acute infection.
• To correlate this sign with obstruction and infection in the urinary tract.

Main Methods:

• Retrospective analysis of excretory urograms.
• Identification of a specific radiological finding: opacification of the pelvocalyceal wall.
• Correlation with clinical and laboratory findings of infection and obstruction.

Main Results:

• A distinct radiological sign of pelvocalyceal wall opacification was identified in the early phase of excretory urography.
• This sign was consistently observed in patients with acute infection within an obstructed urinary tract system.

Conclusions:

• Pelvocalyceal wall opacification is a novel, early radiological indicator of acute infection in obstructed urinary tracts.
• This sign may aid in the prompt diagnosis and management of complicated urinary tract infections.
