Spinal or general anesthesia for inflammation after kidney stone removal (PCNL)

Comparison of Spinal and General Anesthesia on Systemic Inflammatory Response in Patients Undergoing Percutaneous Nephrolithotomy: Evaluation of SII, SIRI, AISI, NLR, and RDW

Observational Elazıg Fethi Sekin Sehir Hastanesi · NCT07326670

What this trial studies

This observational study compares perioperative changes in routine blood-based inflammatory markers between patients who receive spinal anesthesia and those who receive general anesthesia for percutaneous nephrolithotomy (PCNL). Preoperative and postoperative complete blood count values will be used to calculate indices such as SII, SIRI, AISI, NLR, and RDW, and these will be compared alongside clinical outcomes. Adult patients (ASA I–III) treated at a single center in Elâzığ, Turkey are eligible, while patients with active infection, malignancy, chronic inflammatory disease, immunosuppression, pregnancy, or ASA IV–V are excluded. Anesthesia is not assigned by the study; routine clinical care determines the approach and investigators analyze the resulting data.

Who should consider this trial

Good fit: Adults aged 18 and older undergoing PCNL who are ASA physical status I–III and who do not have active infection, cancer, chronic inflammatory disease, pregnancy, or use immunosuppressive therapy.

Not a fit: Patients who are ASA IV–V, children under 18, pregnant individuals, or those with active infection, malignancy, chronic inflammatory conditions, or on immunosuppressive medications are unlikely to be eligible or to benefit from the findings.

Why it matters

Potential benefit: If successful, the findings could help clinicians choose the type of anesthesia that minimizes postoperative inflammation and related complications after PCNL.

How similar studies have performed: Prior studies in other surgical settings have sometimes found differences in inflammatory markers between spinal and general anesthesia, but evidence specifically for PCNL is limited.
