title: Impact of preoperative antiandrogen medication and nerve-sparing surgery on the outcome of radical prostatectomy.
abstract: OBJECTIVE
  Radical prostatectomy in antiandrogen-medicated patients, as well as nerve-sparing surgery, has increased within recent years. We investigated the impact of antiandrogen medication on loss of blood and of nerve-sparing surgery on continence and potency.
  
  
  METHODS
  A total of 401 men who underwent radical prostatectomy between January 1995 and September 1999 at our clinic were asked about antiandrogenic medication prior to radical prostatectomy and about daily life activities, overall satisfaction, voiding ability, and sexual activities. Consumption of erythrocyte concentrates and cryoprecipitated plasma was taken from the records.
  
  
  RESULTS
  The average follow-up was 36 months. Seventy-two percent (n = 289) of our patients replied. Sixty-seven men (23%) who replied to our questionnaire had received antiandrogen medication prior to radical prostatectomy. In 53 (18%) of the men, the nerve-sparing technique was used. In antiandrogen-medicated patients, we observed a significantly elevated consumption of erythrocyte concentrates (antiandrogen-medicated 0.93, not antiandrogen-medicated 0.44; P = 0.013) and of cryoprecipitated plasma (antiandrogen-medicated 0.39, not antiandrogen-medicated 0.08; P = 0.010). Patients who underwent the nerve-sparing technique reported better results in daily life activities, general health status, International Prostate Symptom Score (IPSS), and continence.
  
  
  CONCLUSIONS
  Our results point to a higher quality of life in patients who had undergone nerve-sparing surgery.
