진찰시 환자 자세가 요도 운동성 측정에 미치는 영향

Abstract

Objective: To determine the effect of patient position on mobility of female urethrovesical junction. Methods: Total fifty patients who visited urgynecology clinic were enrolled in this study. We compared maximal strain Q-tip angle with resting Q-tip angle in supine and sitting position. Also compared proportion of positive Q-tip test between supine and sitting position. Wilcoxon singed-rank test and McNemar test were used to compare the results. Results: Maximal strainging Q-tip angle in supine position was significantly greater than sitting position(p<0.05) and difference of Q-tip was also greater in supine position than sitting position(p<0.05). Thirty patients had a positive Q-tip test in supine position(70%) but only twenty-one patients had a positive Q-tip test in sitting position(60%). Conclusion: The patient position had a great effect on the mobility of urethrovesical junction especially in supine position than sitting position. Because the mobility of urethrovesical junction has a great role in to select an appropriate surgery, our results has great implications for the evaluation of patients with stress urinary incontinence.
