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.
