Abnormal uterine bleeding in adolescents: ultrasound evaluation of uterine volume

Abstract

Objective: To evaluate ultrasonographic measurements of internal genitalia in girls suffering from abnormal uterine bleeding (AUB) and to compare the appearances with those of healthy girls. DESIGN Prospective case – control study.

Methods: One hundred and five not sexually active adolescent girls were enrolled – 67 patients were suffering from AUB and there were 38 healthy peers. The groups did not differ in chronological age, or in postmenarcheal age. All girls underwent assessment of their history, clinical data and transabdominal pelvic ultrasound to evaluate their uterus and ovaries. In order to avoid the impact of endometrium cycle fluctuations, the uterine volume was calculated including and excluding its thickness.

Results: The uterine volume among the girls suffering from AUB was significantly larger than in the control group. The mean uterine volume including endometrium in the study and control groups was 63.2 ± 24.8 and 47.8 ± 17.5 cm³, respectively (p=.001), and excluding the endometrium was 34.7 ± 13.1 and 29.1 ± 13.8 cm³ (p=.043). We did not find any significant difference in ovarian volume between the groups.

Conclusions: The girls in the AUB group have significantly larger uterine volume than healthy girls. This finding does not depend on endometrial thickness.

摘要

目的：探讨罹患异常子宫出血(AUB)的女孩内生殖器的超声检查方法, 并与健康女孩的超声表现进行比较。设计：前瞻性病例对照研究。

方法:对105例性行为不活跃的青春期女孩进行调查, 其中67例为AUB患者, 38例为健康同龄人。两组在实际年龄和月经初潮年龄上没有差异。所有女孩都接受了病史、临床资料和经腹盆腔超声检查, 以评估她们的子宫和卵巢。为了避免子宫内膜周期性波动的影响, 分别对包含和不包含内膜的子宫体积进行计算。

结果:AUB组子宫体积明显大于对照组。研究组和对照组包含子宫内膜的平均子宫体积分别为63.2±24.8和47.8±17.5cm3 (p =.001), 不包含子宫内膜的平均子宫体积分别为 34.7±13.1 和29.1±13.8 cm3 (p= .043)。两组间卵巢体积无明显差异

结论:AUB组子宫体积明显大于健康组。这一发现与子宫内膜厚度无关。
