NCT06798753

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).

Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Ureteral Stone Fragments Identified Endoscopically

    Endoscopic identification of ureteral stone fragments will be used to compare rate of ureteral stone fragments upon completion of PCNL while using OBC versus 5FR-UC.

    During procedure, up to 5 hours

Secondary Outcomes (3)

  • Length of Procedure

    During procedure, up to 5 hours

  • Number of Participants With Intraoperative Complications

    During procedure, up to 5 hours

  • Number of Participants With Stent Placement

    during procedure, up to 5 hours

Study Arms (2)

Occlusion Balloon Catheter

ACTIVE COMPARATOR

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.

Device: Occlusion Balloon Catheter

5FR Ureteral Catheter

ACTIVE COMPARATOR

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.
