Which type of catheter is typically used for selective renal angiography?

The J-Catheter is typically used for selective renal angiography due to its unique shape and design features that facilitate the cannulation of renal arteries. The curvature of the J-shaped tip allows for easier navigation through the arterial system, making it effective in selectively targeting the renal arteries without damaging surrounding tissues. This catheter's ability to maneuver through bends and branches within the vascular system is particularly vital in achieving optimal imaging of the renal vasculature.

While other catheters may serve various purposes in vascular procedures, their designs are not specifically tailored for the selective engagement of renal arteries as effectively as the J-Catheter. Therefore, the use of the J-Catheter stands out in its effectiveness and suitability for this specific application in renal angiography.
