Urinary ascites and obstructive uropathy.

The British Journal of Radiology

|February 1, 1975

Summary

This summary is machine-generated.

Urinary ascites in infants, often caused by posterior urethral valves, presents as an opaque halo in the kidneys on excretory urography. This finding aids in diagnosing obstructive uropathy in newborns.

Area of Science:

Pediatric Urology
Diagnostic Imaging
Nephrology

Background:

Urinary ascites is a rare condition in infants.
Obstructive uropathy can lead to significant renal complications.
Early diagnosis is crucial for managing infant urinary ascites.

Purpose of the Study:

To report on seven infant cases of urinary ascites.
To describe the characteristic radiographic findings.
To identify the common cause of this condition.

Main Methods:

Case series of seven infants with urinary ascites.
Diagnostic imaging using excretory urography.
Analysis of radiographic findings, particularly delayed films.

Main Results:

Urinary ascites was associated with obstructive uropathy in all cases.
Extravasation in the kidneys created an opaque halo.
Posterior urethral valves were identified as the primary cause in most cases.

Conclusions:

The opaque halo sign on excretory urography is indicative of urinary ascites in infants.
Posterior urethral valves are a frequent cause of obstructive uropathy leading to urinary ascites.
Prompt diagnosis and management are essential for favorable outcomes in affected infants.
