title: Post-coital gross hematuria: an unusual presentation of benign prostatic hyperplasia.
abstract: OBJECTIVE
  To describe an unusual symptom of benign prostatic hyperplasia (BPH).
  
  
  METHODS
  A patient presented to our urology clinic having experienced post-coital gross hematuria for 2 years. He had not experienced lower urinary tract symptoms (LUTS). A series of examinations were performed to determine the source of bleeding.
  
  
  RESULTS
  The prostate was defined as the active bleeding source responsible for the patient's post-coital hematuria. Endoscopic fulguration did not alleviate the symptom. The use of dutasteride, a dual inhibitor of 5alpha-reductase, solved the problem.
  
  
  CONCLUSIONS
  This study reports for the first time that post-coital gross hematuria is one of the clinical presentations of BPH, which can be successfully treated with 5alpha-reductase inhibitor.
