Is this trial a fit for you?
✓Likely a good fit
Adults over 18 undergoing percutaneous nephrolithotomy under general anesthesia, classified ASA I–III, who consent to participate.
✕Probably not a fit
Patients with contraindications to regional anesthesia, active infection at the block site, coagulopathy, or those unable to report pain scores may not benefit.

What this trial studies
This interventional study investigates the effectiveness of the quadro iliac plane block (QİPB) as a regional anesthesia technique for postoperative analgesia following percutaneous nephrolithotomy. Adult patients (ASA I–III) undergoing the procedure under general anesthesia are included, with exclusions for coagulopathy, infection at the block site, anticoagulant use, allergies to study drugs, unstable vitals, and inability to cooperate with pain assessments. The aim is to determine the block’s analgesic impact and delineate the skin regions anesthetized by QİPB. Safety and feasibility outcomes are likely collected alongside pain scores and opioid use, if applicable.
Why it matters
Potential benefit: If successful, QİPB could provide effective postoperative pain relief and possibly reduce opioid requirements after nephrolithotomy.
How similar studies have gone: Prior regional anesthesia approaches have shown analgesic benefits in similar surgical contexts, but specific evidence for QİPB in this procedure is limited and this study explores its feasibility and effectiveness.
