title: Standardization of the renogram technique for investigating the dilated upper urinary tract and assessing the results of surgery.
abstract: OBJECTIVE
  To recommend a standard technique for the renographic evaluation of the dilated upper urinary tract, and for evaluating the results of surgery.
  
  
  METHODS
  This review is an update of the previously recommended consensus report of the 9th International Symposium of Radionuclides in Nephrourology.
  
  
  RESULTS
  State-of-the-art recommendations are detailed for standardizing common radionuclide investigations.
  
  
  CONCLUSIONS
  Where open, laparoscopic or endourological techniques for treating pelvi-ureteric junction obstruction are under study, results can only be compared by standardizing the investigational techniques. The guidelines produced here are recommended for this purpose.
