Abstract

Introduction and objectives

Transabdominal ultrasonography (US) is the technique of choice for pelvis evaluation in pediatric population. The results of studies regarding US findings show a wide variation. The objectives of our study were: to estimate and correlate uterine and ovarian ultrasound measures (longitudinal diameter and volume) with chronological age (CA), breast Tanner stage (TS) and gynecological age (GA); to evaluate presence and size of follicles in patients according to their pubertal stage; and to determine the endometrial length in prepubertal and pubertal girls.

Material and methods

Unicentric, observational, retrospective, analytical study, conducted between 2010 and 2019. Healthy girls between 8.0 and 16.0 years, attended in the department of radiology were evaluated. Breast TS was evaluated and gynecological age was determined. Ultrasounds were performed by a pediatric diagnostic radiospecialist. Uterus length (UL) and ovarian length (OL) were measured; uterus and ovarian volume were calculated (UV and OV). Diameter of the largest follicle and endometrial thickness were measured.

Results

292 patients were analyzed, mean age was 12.5 years (SD: 2.1). A significant correlation was observed between uterine and ovarian measurements with CA, TS and GA (P < .0001). A significant increase in UL and UV is described as the CA intervals increase, also in ovarian measurements. No significant differences in measurements were observed between TS I and II. An increase was evidenced at menarche. In 30.9% of pubertal patients and 11.8% of prepubertal patients showed ovarian follicles. The endometrium was not measurable in 88.24% of the pre-pubertal population and was always measurable in patients with TS IV and V.

Conclusions

Uterine and ovarian measurements increased with CA and ET (except ET I and II). The greatest increase occurred with menarche. Ovarian follicles and endometrium thickness less than or equal to 1 mm were presented in prepubertal patients.

妇科超声在评估女孩和青少年青春期发育中的作用

经腹部超声是研究儿童和青少年骨盆的首选方法。对这一人群发表的研究各不相同。我们工作的目的是:测量子宫和卵巢超声变量(纵向直径和体积)与实际年龄(ce)、乳腺鞣革期(ET)和妇科年龄(EG)的相关性;根据患者的青春期阶段评估卵泡的存在和大小，并确定青春期前和青春期女孩的子宫内膜厚度。单中心、观察性、回顾性、分析性研究。我们评估了2010年至2019年在诊断成像办公室就诊的8.0至16.0岁的健康女孩。我们评估了乳房ET，确定了ge。超声检查由一名专门从事儿科诊断放射学和影像诊断的专业人员进行。我们测量了子宫纵向直径(DLU)和卵巢纵向直径(DLO)，并计算了两个体积(VU和VO)。我们测量了最大直径的卵泡和子宫内膜厚度。292例患者进行了分析;平均年龄为12.5岁(平均:2.1岁)。子宫和卵巢测量与EC、ET和EG有显著相关性(p < 0.0001)。在卵巢测量中，随着EC间隔的增加，DLU和VU显著增加。在ET I和ET II之间没有观察到显著差异。一项研究发现，在怀孕期间，女性的月经周期增加了50%，而男性的月经周期增加了50%。30.9%的青春期患者和11.8%的青春期前患者有卵巢卵泡。88.24%的青春期前人群的子宫内膜无法测量，而ET IV和v患者的子宫和卵巢测量均随EC和ET增加而增加(ET I和ET II除外)，增幅最大的是初潮。青春期前患者卵巢卵泡和子宫内膜厚度小于或等于1mm。经腹超声(美国)是儿科人群盆腔评估的首选技术。结果研究有关调查结果显示a wide variation)。我们研究的目的是:估计子宫和卵巢超声测量(纵向直径和体积)与年龄(CA)、乳房鞣革期(TS)和妇科年龄(GA)的关系;根据患者的青春期阶段，评估其卵泡的存在情况和大小;= =地理= =根据美国人口普查，这个县的总面积为，其中土地和(1.5%)水。2010年至2019年进行的单中心观察性回顾性分析研究。对在放射科就诊的8.0至16.0岁健康女孩进行了评估。对乳房进行了评估，并确定了妇科年龄。超声是由儿科诊断放射学家进行的。测量子宫长度(UL)和卵巢长度(OL);= =地理= =根据美国人口普查，这个县的总面积为，其中土地和(1.1%)水。= =地理= =根据美国人口普查局的数据，该县总面积为，其中土地和(1.5%)水。292例患者分析，平均年龄12.5岁(SD: 2.1)。子宫和卵巢测量与CA、TS和GA有显著相关性(P < .0001)。促请增加紫外线UL and is公民as the CA intervals增加,还in ovarian measurements。= =地理= =根据美国人口普查局的数据，这个县的总面积，其中土地和(1.1%)水。这是一个明显的增加。= =地理= =根据美国人口普查，cdp的土地面积为。88.24%的青春期前人群的子宫内膜无法测量，而TS IV和v患者的子宫和卵巢测量均在CA和ET患者中增加(ET I和II除外)。在青春期前患者中，卵巢卵泡和子宫内膜厚度小于或等于1毫米。
