Q-tip tests were carried out on 63 women to determine optimal placement and the effects of bladder fullness and significant anterior vaginal wall relaxation. Significantly higher maximum straining angles were observed when the tip of the Q-tip was placed at the urethrovesical junction or the proximal urethra, compared with placement in the bladder (P less than .05), midurethra (P less than .01), or distal urethra (P less than .01). Bladder fullness did not alter the results significantly. There were no significant differences in resting or maximum straining angles when patients with significant anterior vaginal wall relaxation and genuine stress incontinence were compared with continent women who had significant anterior vaginal wall relaxation. However, in the absence of significant anterior vaginal wall relaxation, women with genuine stress incontinence had significantly higher maximum straining angles than those with bladder instability (P less than .05) or control subjects (P less than .05). The Q-tip test, if performed correctly, is an easy, inexpensive, and reliable method of quantifying mobility of the bladder neck and proximal urethra in continent or incontinent women with or without pelvic relaxation.
对63名女性进行了棉签试验，以确定最佳放置位置以及膀胱充盈和明显阴道前壁松弛的影响。与放置在膀胱（P<0.05）、尿道中段（P<0.01）或尿道远端（P<0.01）相比，当棉签尖端置于尿道膀胱交界处或尿道近端时，观察到明显更高的最大用力角度。膀胱充盈对结果无显著影响。有明显阴道前壁松弛和真性压力性尿失禁的患者与有明显阴道前壁松弛的控尿女性相比，静息或最大用力角度无显著差异。然而，在无明显阴道前壁松弛的情况下，真性压力性尿失禁的女性最大用力角度明显高于膀胱不稳定女性（P<0.05）或对照组（P<0.05）。如果操作正确，棉签试验是一种简单、廉价且可靠的方法，可用于量化有或无盆底松弛的控尿或尿失禁女性膀胱颈和尿道近端的活动度。
