Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older who are scheduled for percutaneous nephrolithotomy and are not currently immunosuppressed.

Probably not a fit

Patients who are under 18 years of age or currently immunosuppressed will not benefit from this study.

What this trial studies

This observational study aims to develop a risk stratification system for predicting postoperative infectious complications and systemic inflammatory responses in patients undergoing percutaneous nephrolithotomy (PCNL). By analyzing pre-and post-operative blood endotoxin levels, the researchers hope to identify patients at higher risk for infections. The study will involve adults scheduled for PCNL at Uhealth tower and Jackson Memorial Hospitals, focusing on their blood profiles before and after the procedure.

Why it matters

Potential benefit: If successful, this study could lead to improved patient outcomes by allowing for better risk assessment and management of infections following kidney stone surgery.

How similar studies have gone: While this approach is innovative, similar studies focusing on endotoxin levels and infection risk in surgical settings have shown promise, suggesting potential for success.
