Abstract
Purpose:
Occasionally during percutaneous surgery, significant contrast extravasation obscures the field, making fluoroscopic access no longer feasible. Herein, we describe a salvage technique.
Materials and Methods:
The cystoscopically placed, open-end ureteral catheter is exchanged with an angled-tip angiographic catheter. With the aid of a guidewire and under fluoroscopic guidance, the tip of the catheter is placed in a posterior calix. The “bull's eye” technique is then applied to direct the needle into the tip of the catheter. This technique was used in four cases over a 7-year period.
Results:
Successful access was accomplished in all cases through a middle or upper calix.
Conclusion:
The catheter serves as a target for providing access to the renal collecting system and facilitates final tract dilatation.
