title: [Value of transrectal ultrasonography in the diagnosis of midline prostatic cysts].
abstract: OBJECTIVE
  To assess the value of transrectal ultrasonography (TRUS) in the diagnosis of midline prostatic cysts.
  
  
  METHODS
  We retrospectively analyzed the TRUS manifestations of 87 cases of midline prostatic cysts.
  
  
  RESULTS
  Of the total number, 33 cases were diagnosed as Müllerian duct cysts, 21 cases ejaculatory duct cysts and the other 33 cases undifferentiated midline prostatic cysts; 19 cases had dilated seminal vesicles, 19 seminal vesicle agenesis, 9 seminal vesiculitis and 5 dilation of the ejaculatory duct.
  
  
  CONCLUSIONS
  TRUS, convenient, sensitive, safe and non-invasive, is a desirable method for the diagnosis of midline prostatic cysts.
