OBG · Postpartum haemorrhage and emergencies: placenta percreta and bladder

Sample item

A woman with a previous caesarean section and placenta praevia at 33 weeks develops painless gross haematuria. Urine culture is sterile. What is the most likely cause?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Placenta percreta invading the urinary bladder

Placenta percreta can penetrate the full thickness of the myometrium and reach the bladder wall, causing haematuria. Cystoscopy and MRI help to define the extent, and delivery is planned in a centre with urological and surgical support.

Option by option

  • A. Placenta percreta invading the urinary bladder (correct)

    Correct. Bladder invasion by a percreta gives sterile haematuria in a woman with scar and praevia.

  • B. Vasa praevia rupture

    Vasa praevia bleeding is fetal blood loss from the vagina after membrane rupture, not haematuria.

  • C. Uterine scar dehiscence

    Scar dehiscence causes pain and uterine or fetal compromise, not isolated haematuria.

  • D. Acute cystitis

    Cystitis would show dysuria and a positive culture.
