Sonography of post-cesarean-section bladder-flap hematoma.

Area of Science:

• Obstetrics and Gynecology
• Surgical Complications
• Diagnostic Imaging

Background:

• Bladder-flap hematoma is an uncommon complication following lower-uterine transverse cesarean sections.
• It results from bleeding at the incision site, forming a hematoma between the bladder and the lower uterine segment.

Purpose of the Study:

• To describe the clinical, sonographic, and surgical findings in patients with bladder-flap hematoma.
• To evaluate the utility of sonography in diagnosing and guiding therapy for this complication.

Main Methods:

• Retrospective review of seven patients diagnosed with bladder-flap hematoma.
• Analysis of clinical presentation, sonographic imaging, and surgical outcomes.
• Sonographic evaluation focused on the characteristics of the mass between the bladder and uterus.

Main Results:

• Sonography consistently identified a solid or complex mass between the posterior bladder wall and anterior uterine wall in all patients.
• Differentiation between hematoma and infected hematoma/abscess was challenging, though the presence of air indicated infection.
• Ultrasound proved to be an accurate and easily applicable diagnostic tool.

Conclusions:

• Sonography is highly effective in the easy and accurate detection of bladder-flap hematomas.
• Diagnostic imaging significantly aids in focusing and guiding therapeutic interventions for this cesarean section complication.
