Strain Elastography in Urogynecology: Functional Imaging in Stress Urinary Incontinence

Stress urinary incontinence (SUI) is the most common subtype of female urinary incontinence, affecting up to one in four women and markedly reducing quality of life. Its pathophysiology primarily involves impaired suburethral and paraurethral support, resulting in decreased tissue stiffness and urethral hypermobility. Conventional imaging provides anatomical detail but is limited in its ability to assess pelvic floor biomechanics. This narrative review summarizes current evidence on strain elastography (SE) as a functional imaging modality in urogynecology, with emphasis on evaluating suburethral tissue stiffness in women with SUI. A narrative review was performed using PubMed (2000–2025). Primary searches (“strain elastography” AND “female stress urinary incontinence”; “stress incontinence” AND “elastography”) yielded 19 records, of which 12 were included after screening. Owing to the limited number of SE-specific studies, the review was expanded to include shear wave elastography research, key guidelines, and biomechanical literature on pelvic floor ultrasound in adult women with SUI. SE provides a non-invasive, real-time method for assessing tissue stiffness, bridging the longstanding gap between anatomical and biomechanical evaluation. Current evidence supports SE as a feasible and promising diagnostic adjunct for the functional assessment of SUI in women.
