What this Trial Is About
Researchers are studying the effect of the quadro iliac plane block on pain relief after surgery in patients having percutaneous nephrolithotomy, a procedure to remove kidney stones. The study aims to find out how well this nerve block reduces pain and which skin areas it affects. This randomized, quadruple-masked trial compares patients receiving the block with those who do not. Participants are divided into two groups. The control group receives no additional procedures after surgery. The other group undergoes the quadro iliac plane block after surgery, performed with ultrasound guidance while the patient lies on their side. A needle is used to inject 40 mL of 0.25% bupivacaine between specific muscles near the iliac crest to provide anesthesia. This block is intended to reduce postoperative pain. During the study, pain levels will be measured using a Numeric Rating Scale over 24 hours after surgery. Researchers will also assess the skin areas affected by the block two hours after surgery and monitor total tramadol pain medication use within 24 hours. Patients will be monitored for safety and will be followed until 24 hours postoperatively. The study includes adult patients aged 18 to 65 years undergoing the specified surgery.
