A case of posterior urethral valve diagnosed by ultrasound in antenatal and pathology: A case report.

Abstract

Rationale: Posterior urethral valve is a rare disease, prenatal diagnosis and prognosis evaluation are particularly important.

Patient concerns: A 25-year-old pregnant woman was found enhanced parenchymal echo in both kidneys, subcapsule urinary cyst formation in both kidneys, bladder enlargement of the fetus during prenatal ultrasonography at 25 W + 4 of gestation. It was accompanied by fetal pericardial effusion and oligohydramnios.

Diagnoses: Fetal posterior urethral valve.

Interventions: After detailed prenatal evaluation, labor was induced and fetal autopsy was performed.

Outcomes: Fetal autopsy pathology confirmed the prenatal judgment.

Lessons: Prenatal ultrasonography can diagnose posterior urethral valve through typical image manifestations and can make a certain judgment for prognosis evaluation.
