Ureteral ObstructionNCT00199472
Comparison of Dynamic Contrast Enhanced CT and Diuretic Renogram in The Evaluation of UPJO
An observational study of Ureteral Obstruction, run by London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's at 1 site in Canada.
Trial summary
Renal blood flow is inversely related to obstruction. We propose that this imaging will be as effective as the diuretic renogram in the functional diagnosis of obstruction. Furthermore, dynamic contrast CT scanning may also add anatomic information necessary for the surgical treatment. Read more about this study

The record says: withdrawn, as of the sponsor's last update on 25 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
