Abstract:
Objective:To explore the value of 3D/4D translabial ultrasound in the diagnosis and differential diagnosis of female urethral diverticulum.Methods:The paired chi-square test was used to compare the diagnostic accuracy of 2D translabial ultrasound and 3D/4D translabial ultrasound in 21 suspected urethral diverticulum patients who visited the Third Affiliated Hospital of Sun Yat-Sen University from November 2013 to January 2020. And Kappa consistency test was used to evaluate the consistency between these two methods and the pathological results.Results:All 21 patients with suspected urethral diverticulum were diagnosed by postoperative pathology, of which 16 cases were urethral diverticula and 5 cases were paraurethral cysts. The typical appearance of urethral diverticulum on 3D/4D translabial ultrasound was a cystic structure traversing the urethral rhabdosphincter. Additionally, septa, calcification or solid neoplasm can also be seen in some cases. The sensitivity/specificity of 2D translabial ultrasound and 3D/4D translabial ultrasound were 75.00%/100% and 93.75%/100%, respectively, no statistical differences were found both in sensitivity and specificity between these two methods(all P>0.05). The Kappa consistency test showed that the consistency between 2D translabial ultrasound and pathological diagnosis was general (Kappa=0.588, P=0.003), while the consistency between 3D/4D translabial ultrasound and pathological diagnosis was good (Kappa=0.877, P<0.001). Conclusions:3D/4D translabial ultrasound has a high value in the diagnosis of female urethral diverticulum, and it is worthy of clinical application.
