The fetal urinoma revisited

Area of Science:

• Pediatric Urology
• Fetal Medicine
• Nephrology

Background:

• Fetal urinoma is a rare diagnosis signifying significant urinary tract obstruction.
• Understanding its causes and outcomes is crucial for fetal kidney health.

Observation:

• A single center reviewed 25 cases of fetal urinoma diagnosed or referred over 11 years.
• The primary causes identified were posterior urethral valves and ureteropelvic junction obstruction.

Findings:

• Posterior urethral valves and ureteropelvic junction obstruction were the most common causes of fetal urinoma.
• Fetal interventions, including drainage and cystoscopic procedures, were performed in 4 cases.

Implications:

• Early diagnosis of fetal urinoma is critical for assessing and managing underlying kidney obstruction.
• Timely intervention can potentially improve long-term renal function in affected infants.
