Abstract:
Objective To study the diagnostic value of high-frequency color Doppler ultrasound (CDU) on the obstruction of proximal deferent duct. Methods One hundred and twenty-three patients with scrotal diseases (aged 23-67 years old) were examined by CDU with 5-10 MHz transducer. Among the cases, infertility was in 88, vasoligation in 8, and epididymal nodes in 27. The sonographic appearances of the obstruction of the deferent duct were analysed, compared with that of normal deferent duct. Results Of the 123 cases, the obstruction of the deferent duct was in 72, included absence of deferent duct in 6, epididymal malformation in 9, epididymitis in 37, epididymal neoplasms in 5, and dilatation of testic rete and testic efferent duct in 3. Twenty-two patients underwent surgery, confirmed the sonographic appearances of the obstruction of proximal deferent duct. Conclusions Obstruction of proximal deferent duct could be assessed by high-frequency CDU. It is helpful for distinguishing the causes of the obstruction of proximal deferent duct and choosing their therapy scheme.
