Occlusion Balloon vs. 5FR Ureteral Catheter

The occlusion balloon catheter (OBC) is a type of ureteral catheter equipped with a small inflatable balloon at its tip. When inflated, the balloon can help prevent the migration of stone fragments.

The 5FR ureteral catheter (5FR-UC) is an open-ended small-caliber tube inserted at the beginning of PCNL to facilitate visualization of the collecting system using fluoroscopy and assist with renal access.
