Transrectal Sonographic Investigation of Urethral and Paraurethral Structures in Women with Stress Urinary Incontinence

摘要: Transrectal sonography of the urethra was used in 14 asymptomatic volunteers, 37 women with frequency-urgency syndrome, 42 patients mild stress urinary incontinence, and 18 severe incontinence. Transverse scanning over midurethra performed crosssectional images urethral paraurethral structures were compared among four groups, P < 0.05 being considered statistically significant. The total cross-sectional area significantly smaller incontinence than those without this disorder (86.7 ± 29.9 versus 104 35.6 mm2, = 0.005); difference resulted from a peripheral striated muscle component (42.8 20.7 58.3 27.3 0.001). thickness urethropelvic ligaments thinner (5.9 1.7 8.9 2.1 mm, distribution around variable: complete surrounding noted 35.7% control 48.6% patients, but only 16.7% 5.3% disease. Bladder neck incompetence seen none women. length pubourethral similar groups. Our finding showed that had ligaments. These defects continence mechanisms might have great implications pathophysiology is valuable investigative tool assessing conditions before deciding treatment modality.
