Bilateral spontaneous urinary extravasation in ureteral obstruction

Area of Science:

• Urology
• Nephrology
• Radiology

Background:

• Spontaneous urinary extravasation is an uncommon complication of ureteral obstruction.
• It typically presents as urine leakage into the retroperitoneum or peritoneal cavity.

Observation:

• A rare case of bilateral spontaneous urinary extravasation secondary to ureteral obstruction is presented.
• Uniquely, the extravasation on one side was confined within the renal capsule.

Findings:

• The case highlights the varied presentations of urinary extravasation.
• Subcapsular renal urinoma is a possible, albeit infrequent, manifestation.

Implications:

• This finding expands the differential diagnosis for renal capsular fluid collections.
• Awareness of this presentation is crucial for accurate diagnosis and management of ureteral obstruction complications.
