Abstract：
OBJECTIVE: The aim of this study was to compare the differences between angles of bladder neck in girls with overactive bladder and those in healthy ones using transabdominal ultrasonography.
METHODS: This study consists of 28 girls complicated with overactive bladder (Group I) and 40 healthy girls (Group II). The anteroposterior vesical wall angle (APVA), urethroposterior vesical wall angle (UPVA), urethroanterior vesical wall angle (UAVA), thickness of bladder mucosa, distance of urethral orifices, and distance between ureter and urethra orifice were measured in supine position using transabdominal ultrasonography. The results were compared between the two groups.
RESULTS: UAVA in Group I was higher than Group II (135.2 ± 12.2 mm vs. 117.4 ± 14.0 mm; p = 0.009). UPVA was smaller in Group I than Group II (114.6 ± 19.5 mm vs. 135.3 ± 16.5 mm; p = 0.014). The distance between the ureteral orifices was 31.8 ± 8.5 mm in Group I and 17.0 ± 4.1 mm in Group II (p < 0.001). There was no statistically significant difference between groups in terms of APVA, bladder mucosa thickness, and distance between ureter and urethra orifice (p > 0.05).
CONCLUSIONS: Bladder neck dynamics may play an important role in overactive bladder pathophysiology due to differences in UPVA, UAV, and location of ureteral orifices in this patient population.

摘要：
目的：本研究的目的是通过经腹超声检查比较膀胱过度活动症女孩和健康女孩膀胱颈角度的差异。
方法：本研究包括28名患有膀胱过度活动症的女孩（I组）和40名健康女孩（II组）。膀胱前后壁角（APVA），尿道膀胱后壁角（UPVA），尿道前膀胱壁角（UAVA），膀胱粘膜厚度，尿道口距离,使用经腹超声在仰卧位测量输尿管和尿道口之间的距离。比较两组的结果。
结果：I组的UAVA高于II组（135.2±12.2mmvs.117.4±14.0mm;p=0.009)。第一组的UPVA比第二组小（114.6±19.5mmvs.135.3±16.5mm;p=0.014)。第一组输尿管口之间的距离为31.8±8.5mm，第二组为17.0±4.1mm（p<0.001）。两组之间在APVA方面无统计学差异，膀胱粘膜厚度，输尿管和尿道口之间的距离（p>0.05）。
结论：由于UPVA的差异，膀胱颈部动力学可能在膀胱过度活动症的病理生理学中起重要作用，无人机,以及该患者人群中输尿管口的位置。
