Clinical Trial Summary

Randomized comparison of patient outcomes following fluoroscopic guided PCNL versus ultrasound-guided PCNL.

Description:

This study is a randomized controlled trial that compares the operative outcomes and complications of fluoroscopic guided-percutaneous nephrolithotomy versus ultrasound-guided PCNL for renal stones. This study will be a prospective randomized controlled clinical trial with patients who have already agreed to undergo PCNL. Patients will be randomized at a 1:1 ratio to receive either PCNL under fluoroscopic guidance or PCNL under ultrasound guidance. Patients will be asked to complete pre-operative, and postoperative quality of life questionnaires, and to allow the collection of one additional vial of blood for measurement of factors associated with inflammation.
