Clinical and Transperineal Ultrasound Findings in Females with Stress Urinary Incontinence Versus Normal Controls

Abstract

Study was aimed at comparing clinical and transperineal ultrasound findings of females with stress urinary incontinence and normal controls. Between 2004 and 2005, 40 women with stress urinary incontinence (mean age 47.5 years) diagnosed by history via ICIQ-SF (International consultation on Incontinence Questionnaire-Short Form) and 40 healthy female volunteers without any incontinence or LUTS (mean age 42.1 years) underwent transperineal ultrasonography for determination of posterior urethrovesical (beta) angle, bladder neck funneling and hypermobility of urethra. These findings were compared between patients and controls with regard to clinical data. Beta angle wider than 130 degrees, bladder neck funneling and hypermobility of urethra with transperineal ultrasonography were more common among cases than controls. LR (Likelihood Ratio) for urinary incontinence of these parameters was 2.5, 2.1 and 2, respectively. Perineal ultrasonography is highly associated with clinical findings. Hypermobility of urethra had highest sensitivity for diagnose of stress urinary incontinence but the specificity of bladder neck funneling in perineal sonography was higher.

Transperineal ultrasound evaluation of females with stress urinary incontinence

“…13 Another study found beta angle to be significantly wider in SUI patients, when compared to controls, both at rest and during straining, while, the alpha angle varied significantly only during valsalva. 5 On analyzing the TP U/S findings in the current study, no statistical significant difference between cases and controls at rest, but on straining, the dynamic pubourethral distance (reflecting bladder neck descent) was significantly different between patients with stress urinary incontinence and the control group (p = 0.04).…”

“…Other imaging modalities as pelvic floor ultrasonography, cysto-urethrography and magnetic resonance imaging (MRI) have been used to evaluate patients with SUI. 5 Pelvic floor ultrasonography can assess and evaluate pelvic floor muscle (PFM) exercise performance by direct visualization of PFM contraction and movement. 6 1 Department of Obstetrics and Gynecology, Ain-Shams University, Cairo, Egypt 2 Department of Radiodiagnosis, Ain-Shams University, Cairo, Egypt Transperineal (TP) ultrasonography seems to be a reliable modality for the assessment of bladder neck mobility and PFM contraction and exercise.…”

Ultrasound Characteristics of Patients with Urinary Stress Incontinence with or without Genital Prolapse

“…Similarly to Dietz [9], we found that in the USIGP group in which GP and cystocele were present, the ultrasound image demonstrated an intact retrovesical angle (β), i.e., it was significantly smaller in this group than in the USI group during the VM and these patients often were continent. Hajebrahimi et al [10] found a significantly wider retrovesical angle (β) in patients with USI (n=40) compared with normal controls (n=40), as well as greater mobility of the urethra and BN. Minardi et al [11] found that retrovesical-angle rotation and BN-descent during VM were strongly associated with genuine USI.…”

Effect of tamsulosin versus prazosin on clinical and urodynamic parameters in women with voiding difficulty: a randomized clinical trial

“…Voiding dysfunction may occur as a result of anatomical or neurological abnormalities of the pelvic floor 9. The purpose of this study was to investigate the effects of tamsulosin and prazosin on female voiding dysfunction.…”
