Abstract:
Objective To evaluate the application of dynamic magnetic resonance imaging in the diagnosis of female stress urinary incontinence(SUI). Methods Dynamic magnetic resonance imaging(DMRI)were performed on 30 healthy female volunteers and 35 female SUI patients.DMRI of the pelvic floor at rest and OR maximal strain were performed by using sagittal T2-weighted fast gradient sequences.The distance of Urethra-vesical junction to the pubococcygeal line,the posterior vesicourethral angle and angle of inclination of the urethral axis were measured at rest and on maximal strain position.The t-value exact test were used to analyze the data. Results At rest the Urethravesical junction laid above pubococcygeal line on both control and SUI groups.Mean distance from the Urethra-vesical junction to pubococcygeal line at rest had no difference between the two groups.On straining,the mean Urethra-vesical junction descent distance in the SUI group(-0.9±1.1cm)was significantly higher than in control group(-0.14±0.3 cm),(P＜0.001).On straining,the mean angle of urethral inclination in the SUI group(65±37°)was significantly bigger than in control groups (17±21°),(P＜0.05).The posterior vesicourethral angle in the SUI groups(156±36°)was significantly bigger than in control groups(113±28°),(P＜0.05). Conclusion Dynamic magnetic resonance imaging is a non-invasive.easily applied method in the diagnosis of SUI.
