Relationship between Parameters of Perineal Ultrasonography and Severity of Symptom in Genuine Stress Urinary Incontinence Patients

ABSTRACT

PURPOSE: The goal of this study is to know the relationship between the parameters of perineal ultrasonography and severity of symptom in stress urinary incontinence patients. MATERIALS AND METHODS: We retrospectively examined total 68 patients with stress urinary incontinence who were diagnosed by physical examination, history, urinalysis and urodynamic study. The patients were divided into three group, 1, 2, 3 by Stamey grade in order of each grade I, II, III. We measured the posterior urethrovesical angle(PUVA) at rest and during strain, descent and funneling of bladder neck using perineal ultrasonography. RESULTS: The mean PUVA at rest was 123.9+/-24.0degrees. In group 1, the angle was 124.6+/-20.6degrees, in group 2, 121.4+/-27.1degrees, in group 3, 138.6+/-4.9degrees(p=0.320). During strain state, the mean PUVA was 139.5+/-24.8degrees. In group 1, the angle was 140.6+/-23.7degrees, in group 2, the angle was 136.9+/-26.5degrees, in group 3, 154.0+/-10.8degrees(p=0.346). The mean descent of bladder neck was 10.8+/-4.4mm. In group 1, the descent was 9.9+/-5.8mm, in group 2, 11.3+/-3.5 mm, in group 3, 11.8+/-0.8 mm(p=0.455). The number of cases presenting funneling of bladder neck was 3, 4, 2 in each group(p=0.150). CONCLUSION: There was no relationship between the parameters of perineal ultrasonography and the severity of symptom in stress urinary incontinence patients.
