This study was conducted to evaluate the relationship between the point Aa of the pelvic organ prolapse quantification (POP-Q) system and the Q-tip straining angle and to determine if Q-tip testing is required to assess urethral mobility.
A total of 250 women presenting with urinary incontinence were prospectively examined. Spearman's correlation coefficient was used to assess the degree of correlation between the POP-Q point Aa position and Q-tip values.
Urethral hypermobility was noted in 61% of stage I, 89% of stage II, and 100% of stages III and IV. A substantial negative correlation was found between the point Aa position and the straining Q-tip angle (r=0.683, p<0.0001).
A substantial correlation was found between descent at point Aa and the straining Q-tip angle. The point Aa of the POP-Q system is highly predictive of the abnormal straining urethral angle in women with stage I or greater anterior vaginal wall prolapse.
本研究旨在评估盆腔器官脱垂定量（POP-Q）系统的Aa点与棉签用力角度之间的关系，并确定评估尿道活动度是否需要进行棉签试验。
对250名有尿失禁症状的女性进行前瞻性检查。采用Spearman相关系数评估POP-Q系统Aa点位置与棉签试验值之间的相关程度。
I期患者中61%存在尿道活动过度，II期患者中89%，III期和IV期患者中100%。Aa点位置与用力时棉签角度之间存在显著负相关（r = 0.683，p < 0.0001）。
Aa点下降与用力时棉签角度之间存在显著相关性。POP-Q系统的Aa点对于I期或更严重阴道前壁脱垂女性的异常用力时尿道角度具有高度预测性。
