Abstract
OBJECTIVE: This study was designed to evaluate the significance of transperineal two-dimensional ultrasound in the diagnosis and classification of female stress urinary incontinence (SUI). METHODS: A total of 87 preoperative SUI patients (group A) from the Department of Gynecology of Peking University People's Hospital were included into this study. These patients were further divided into two groups (groups A1 and A2) according to the severity of their disease. In addition, during the same period, 72 age-matched women without SUI were enrolled into this study and assigned as the control group (group B). Through transperineal two-dimensional ultrasound technique, detrusor wall thickness (DWT) was measured in the resting state, the bladder neck descent (BND) was measured under the maximal valsalva maneuver, the proximal urethral rotation angle (α angle) and posterior vesicourethral angle (β angle) were measured, and the formation of the funnel-shaped urethra was observed. RESULTS: Under the resting state, differences in DWT between groups A and B, as well as between groups A1 and A2, were not statistically significant (P> 0.05). The BND, α and β angles were significantly larger in group A than in group B under the maximal Valsalva maneuver; and the differences were statistically significant (P< 0.05). The formation rate of the funnel-shaped urethra was significantly higher in group A (94%) than in group B (3%), and the difference was statistically significant; while the difference between groups A1 and A2 was not statistically significant (P> 0.05). CONCLUSION:Transperineal two-dimensional ultrasound can play an assistant role in the diagnosis of female SUI. However, its role in the assessment of the severity of SUI remains to be studied.
