Summary
Retrograde pyelography can confirm ureteral patency before ureteral stent removal using a simple technique through the stent itself. This method ensures the ureter is clear prior to stent extraction.
Area of Science:
- Urology
- Medical Imaging
Background:
- Ureteral stents are commonly used to maintain ureteral patency.
- Assessing ureteral patency before stent removal is crucial to prevent complications.
Purpose of the Study:
- To describe a simple technique for retrograde pyelography via the ureteral stent.
- To establish ureteral patency prior to ureteral stent removal.
Main Methods:
- A retrograde pyelography procedure is performed through an existing ureteral stent.
- Contrast medium is injected via the stent to visualize the ureter.
Main Results:
- The described technique allows for successful retrograde pyelography.
- Ureteral patency can be effectively assessed prior to stent removal.
Conclusions:
- Performing retrograde pyelography via the ureteral stent is a feasible and simple method.
- This technique aids in confirming ureteral patency before stent removal, potentially improving patient outcomes.
