The purpose of this study was to determine the role of translabial ultrasonography in the investigation of intrinsic urethral sphincter deficiency (ISD), assessing bladder neck hypermobility and urethral diameter in continent and incontinent patients.
A case-control study evaluated 94 women with the diagnosis of urinary incontinence and 96 continent women. Both groups underwent translabial ultrasonography to assess bladder neck hypermobility by means of the x-y coordinate system and urethral diameter. The study was performed at Hospital de Clínicas de Porto Alegre.
Women with urinary stress incontinence showed significantly greater bladder neck descent than continent women and women with urge and mixed incontinence (P = .05). Women with ISD showed significantly larger urethral diameters than control subjects and incontinent women without ISD (P = .05). Of women with urinary incontinence, 78.7% had descent of greater than 10 mm, and 91.7% of the women with ISD had urethral diameters of greater than 6 mm. A urethral diameter of greater than 6 mm showed sensitivity of 91.7% and specificity of 75.6% for ISD.
Translabial ultra-sonography has an important role in the assessment of women with urinary stress incontinence and intrinsic urethral sphincter deficiency.
本研究旨在确定经阴唇超声检查在内在性尿道括约肌缺陷（ISD）检查中的作用，评估尿失禁和非尿失禁患者的膀胱颈活动过度及尿道直径。
一项病例对照研究评估了94例诊断为尿失禁的女性和96例非尿失禁女性。两组均接受经阴唇超声检查，通过x - y坐标系和尿道直径评估膀胱颈活动过度情况。该研究在阿雷格里港临床医院进行。
压力性尿失禁女性的膀胱颈下移明显大于非尿失禁女性以及急迫性和混合性尿失禁女性（P = 0.05）。ISD女性的尿道直径明显大于对照组及无ISD的尿失禁女性（P = 0.05）。在尿失禁女性中，78.7%的膀胱颈下移超过10 mm，91.7%的ISD女性尿道直径超过6 mm。尿道直径大于6 mm对ISD的敏感性为91. Seven percent and a specificity of 75.6%.
经阴唇超声检查在评估压力性尿失禁和内在性尿道括约肌缺陷女性中具有重要作用。
