BLADDER RUPTURE

A single case of antenatal diagnosis of fetal urinary bladder perforation and the development of fetal urinary ascites (1).

ETIOLOGY

• Spontaneous.
• Bladder outlet obstruction causing urinary ascites secondary to urine extraversation through the kidneys and pelvicalyceal system.

ULTRASOUND

• Distended, partially empty urinary bladder.
• Fetal ascites without signs of hydrops.
• Defect in the bladder may be demonstrated.
• Hydronephrosis due to retroperitoneal fluid accumulation.
