Abstract
결론
여성 긴장성 요실금 환자에서 stress leak-point pressure와 maximal urethral closure
pressure는 통계적으로는 유의한 상관관계가 있었으나, 임상적인 연관성은 떨어졌으며, type
Ⅲ 긴장성 요실금인 stress leak-point pressure 60 ㎝H2O 이하를 기준으로
하면 maximal urethral closure pressure가 20 ㎝H2O 이하인 low-pressure
urethra환자를 검출하는데 있어서 민감도와 특이도는 높았지만, 양성 예측율은 매우 낮았다.
또한 stress leak point pressure가 60 ㎝H2O 이하인 38명의 type Ⅲ 긴장성
요실금 환자 중에서 maximal urethral closure pressure가 20 ㎝H2O 이하인
환자는 11명 (28.9%) 뿐이었으며, 27명 (71.1%)은 maximal urethral closure pressure가 20
㎝H2O 이상이었다.
이상의 결과로 stress leak-point pressure가 60 ㎝H2O 이하인 type Ⅲ 긴
장성 요실금과 maximal urethral closure pressure와는 연관성이 떨어지며, type Ⅲ 긴장성
요실금을 진단하는데 있어서 maximal urethral closure pressure의 측정은 도움이 되지 않는
것으로 사료된다.

Purpose: To determine the correlation between the maximal urethral closure pressure
and the stress leak-point pressure in the patients with genuine stress incontinence, and
to define the benefit of maximal urethral closure pressure for detecting type Ⅲ stress
urinary incontinence.
Materials and methods: 115 patients with genuine stress incontinence were evaluated
with multichannel urodynamics. Maximal urethral closure pressures and stress leak-point
pressures were determined and correlated.
Results: There was a statistically significant relationship (p=0.0001) between the stress
leak-point pressure and the maximal urethral closure pressure. However, a correlation
coefficient of 0.50 demonstrated poor clinical relationship. A stress leak-point pressure
less than 60 ㎝ H2O had 91.7% sensitivity, 78.8% specificity and 28.9%
positive predictive value in detecting low-pressure urethra.
Conclusions: The stress leak-point pressure has poor clinical correlation to the
maximal urethral closure pressure. And maximal urethral closure pressure has no
additional benefit for detecting type Ⅲ stress urinary incontinence.
