Brief summary

Occlusion Balloon catheter provides the ability to occlude the exit of the kidney pelvis during percutaneous nephrolithotomy (PCNL) and potentially prevents the migration of stone fragments into the ureter. The necessity for it might be questioned during supine PCNL due to the upward oblique position of the kidney. The objective of the study is to compare the presence of ureteral stone fragments upon completion of supine PCNL with and without using an occlusion balloon catheter (OBC).

Interventions

DEVICEOcclusion Balloon 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.

DEVICE5FR Ureteral Catheter

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.
