title: Sonographic measurement of normal prostate volume and pattern of change with age among male adult Ethiopia patients at Black Lion Specialized Hospital.
abstract: BACKGROUND
  The prostate, the major accessory sex organ in male, its functions are under the control of local and systemic hormones. It causes major source of trouble as the age gets over 40 years.
  
  
  OBJECTIVE
  The aim of the study is to determine the normal volume and rate of growth of the prostate gland in Ethiopian adults and compare with other studies.
  
  
  METHODS
  Transabdominal sonographic measurement of normal volume and patterns of change in prostate volume was performed in 384 of Ethiopian males above 40 years. The patients came for abdominal or pelvic ultrasound study to Black lion specialized hospital from October 1, 2009 to March 30, 2010. All examinations were done by senior radiology residents using standard examination technique. Data were collected on a prepared format.
  
  
  RESULTS
  Our patient's age ranged from 40 to 90 years with an average age of 56.5 years. The prostate volume ranged from 7. 1cc to 169cc with mean and median volume of 42cc and 35cc respectively. Peak volume was seen in the seventh decade of life. The volume of the prostate progressively increases with age, however, the rate of growth was found to be decreasing with increasing age. There was a significant statistical association between lower urinary tract symptoms (LUTS) with prostate volume and age (p value < 0.05).
  
  
  CONCLUSIONS
  The findings of prostate volume of our patients are comparable with other studies and it increases as the age advances while the rate is decreasing. LUTS was found to correlate with volume and age in our patients.
