Evaluation of transperineal ultrasound in diagnosis and grading of female genuine urinary stress incontinence

Abstract

Stress urinary incontinence (SUI) has an observed prevalence of between 4%and 35%. Purpose: To determine the role of transperineal ultrasound in diagnosing stress incontinence, its degree and the possible cause by: Measuring the BN descent, urethral hypermobility, funneling of BN or proximal urethra, urethral diameter, posterior urethra vesical angle, associated cystocele Using color Doppler to detect escape of urine through the urethra. Methods: 52 female patients diagnosed to have genuine stress incontinence using 3 day voiding diary, simple questionnaire and confirmed by standard urodynamics. Classification of stress incontinence into mild, moderate and severe using Valsalva leak point pressure during urodynamic study. Transperineal ultrasound for evaluation of the anterior pelvic compartment regarding: bladder neck descent, urethralhy permobility, Funneling of the BN, posterior urethrovesical angle ,urethral diameter, associatedcystocele, and finally the Doppler detection of urinary escape both at rest and with Valsalva maneuvers. Results: 28/52 cases (53.8%) of SUI didn’t show clinical evidence of cystocele; 11 cases (21.2%) showed grade 1 cystocele and 13cases (25%) showed grade 2 cystocele. The presence or absence of cystocele and also the grade of cystocele did not show a statistically significant relation to the degree of SUI; p=0.089 and 0.086 respectively Conclusion: We came to conclusion that transperineal ultrasound can be used in accurate diagnosis and grading of female urinary stress incontinence with our given cutoff values for bladder displacement, α angle, β angle and urethral diameters and from this grading by transperineal ultrasound comes the novelity of our research.
