Interventions and Outcome Measures

Arms

endotoxin study group

Patients scheduled for Percutaneous Nephrolithotomy (PCNL) as surgical treatment for their kidney stones will be evaluated for postoperative endotoxin levels as a risk marker for sepsis.

Primary outcome measure

  • Number of participants at each endotoxin activity level after surgery. [ Time Frame: Day 1 (within 30 minutes postoperative) ]
  • Corelation of endotoxin activity level with post-operative infectious complication [ Time Frame: up to 24 hours ]
