title: [High-frequency ultrasonography for epididymal stasis after vasectomy].
abstract: OBJECTIVE
  To explore the clinical application of high-frequency ultrasound in the diagnosis and treatment of epididymal stasis after vasectomy.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  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.
