RESUMO
<p><b>OBJECTIVE</b>To explore the clinical application of high-frequency ultrasound in the diagnosis and treatment of epididymal stasis after vasectomy.</p><p><b>METHODS</b>We retrospectively studied the sonographic characteristics of 23 cases of epididymal stasis treated by vasectomy, which were divided into a mild (n = 5), a moderate (n = 11) and a severe group (n = 7) according to the results of color Doppler flow imaging. We analyzed the significance of high-frequency ultrasonography in the treatment of epididymal stasis after vasectomy.</p><p><b>RESULTS</b>High-frequency ultrasonography revealed 14 cases of increased bilateral epididymal volume, 6 cases of left epididymal thickening and 3 cases of right epididymal thickening, mainly the thickening of the epididymal body and tail. After conservative treatment, 18 of the epididymal stasis cases (5 mild, 11 moderate and 2 severe) were improved, and the other 5 severe cases significantly relieved and discharged from hospital following conservative treatment combined with vasectomy reversal.</p><p><b>CONCLUSION</b>Post-vasectomy epididymal stasis has typical sonographic characteristics, and high-frequency ultrasonography has an extremely important application value in the clinical classification, diagnosis and treatment of the disease.</p>
