title: Observation of ureteric diameter in negative intravenous urogram in hospital universiti kebangsaan malaysia.
abstract: BACKGROUND
  This study observed the widest ureteric diameter in negative intravenous urogram (IVU) examinations using low osmolar contrast media.
  
  
  METHODS
  We reviewed a total of one hundred and eighty four ureters from 92 negative IVUs.
  
  
  RESULTS
  The results show a mean diameter for the abdominal ureter of 4.19 mm with an SD of 1.27 mm and a mean pelvic ureteric diameter of 4.45 mm with an SD of 1.37 mm. The upper limits for abdominal ureter and pelvic ureter based on a confidence interval of 95% were 4.37 mm and 4.64 mm, respectively.
  
  
  CONCLUSIONS
  There was no significant difference between the right and left ureteric diameter in both female and male subjects. There was no significant correlation between ureteric diameters and the age of subjects, from the second to the eighth decades.
