Brief summary
Randomized comparison of patient outcomes following fluoroscopic guided PCNL versus ultrasound-guided PCNL.
Detailed 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.
Interventions
PROCEDUREPCNL under fluoroscopic control
Patients receive standard of care treatment for their urolithiasis using standard PCNL under fluoroscopic guidance
PROCEDUREPCNL under ultrasound control
Patients receive standard of care treatment for their urolithiasis using standard PCNL under US guidance
