title: Pretreatment with finasteride decreases perioperative bleeding associated with transurethral resection of the prostate.
abstract: OBJECTIVE
  The efficacy of finasteride in the treatment of gross hematuria associated with benign prostatic hyperplasia is well established. We evaluated a regimen of pretreatment with finasteride in decreasing perioperative bleeding associated with transurethral resection of the prostate (TURP).
  
  
  METHODS
  A prospective analysis compared 25 patients pretreated with finasteride for 2 to 4 months before TURP with 50 patients without pretreatment. Patients in each group were further separated by the amount of prostate tissue resected. Patients were then followed up for perioperative bleeding, defined as a perioperative blood transfusion requirement or a return visit to the emergency room with gross hematuria or clot retention.
  
  
  RESULTS
  None of the patients with less than 30 g of prostate tissue resected experienced perioperative bleeding. In patients with 30 g or more resected, several episodes of bleeding occurred. In the patients pretreated with finasteride, 1 (8.3%) of 12 experienced perioperative bleeding; in the control group, 7 (36.8%) of 19 had an episode of bleeding.
  
  
  CONCLUSIONS
  In patients with large prostate glands undergoing TURP, pretreatment with finasteride appears useful in reducing perioperative bleeding.
