Endometrial biopsy is indicated in Dysfunctional Uterine Bleeding when the endometrial stripe on transvaginal ultrasound is greater than what thickness?

• A. 2 mm
• B. 6 mm
• C. 4 mm
• D. 8 mm

Answer: (C)

Evaluating endometrial pathology in dysfunctional uterine bleeding relies on endometrial thickness seen on transvaginal ultrasound. A thicker endometrial stripe suggests a higher risk of endometrial hyperplasia or cancer, especially in patients with abnormal bleeding. The threshold commonly used to prompt endometrial sampling is greater than 4 mm. So when the stripe exceeds 4 mm, performing an endometrial biopsy is indicated to rule out pathology. A thinner stripe, such as 2 mm, typically carries a lower risk and may not prompt biopsy, while thicker values (like 6 or 8 mm) would also be concerning but the standard cut-off used in practice and exams is 4 mm.
