The investigators aim to investigate the effect of peritubal local anesthetic infiltration on pain scores and analgesic consumption in patients who underwent percutaneous nephrolithotomy.
The investigators aim to investigate the effect of peritubal local anesthetic on pain scores and analgesic consumption in patients who underwent percutaneous nephrolithotomy. Patients aged between 18 and 65 years with renal stone \>2 cm will be included in this study .The patients will be divided into two groups. In Group A , the drug will be infiltrated to the renal capsule, perinephric fat, muscles, subcutaneous tissue, and skin under fluoroscopy with 0.25 percent bupivacaine. This is a widely-used procedure by surgeons in the world. In Group B, no anesthetic will be infiltrated after the end of the procedure.
