Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

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.
Number of participants at each endotoxin activity level after surgery.
The endotoxin activity level assessed from blood samples will be categorized as low (\<0.40), intermediate (0.40-0.59) or high (≥0.60) endotoxin activity level. Analysis will be done via Endotoxin Activity Assay (EAA).
Time frame: Day 1 (within 30 minutes postoperative)
Corelation of endotoxin activity level with post-operative infectious complication
infectious complications include fever, and signs and symptoms of systemic inflammatory response syndrome as evaluated by treating physician.
Time frame: up to 24 hours
