* \*\*Brief Summary\*\*

Percutaneous nephrolithotomy (PCNL) is a common surgical procedure used to remove large kidney stones. Patients often experience moderate to severe pain after this surgery due to the surgical incision and irritation of the kidney and surrounding tissues. Effective pain control after PCNL is important to improve patient comfort, reduce the need for opioid medications, and enhance recovery.

Several regional anesthesia techniques have been developed to reduce postoperative pain. Two of these techniques are the dual-approach external oblique fascial plane block and the erector spinae plane block. Both techniques involve injecting a local anesthetic near specific muscle planes using ultrasound guidance to reduce pain signals from the surgical area. However, it is not yet clear which of these two techniques provides better pain relief after PCNL.

This study aims to compare the effectiveness of the dual-approach external oblique fascial plane block and the erector spinae plane block in controlling pain after PCNL surgery. Adult patients scheduled for PCNL will be randomly assigned to receive one of the two nerve block techniques or standard general anesthesia alone. Pain levels, additional pain medication requirements, patient satisfaction, and any block-related complications will be assessed during the first 24 hours after surgery.

The results of this study may help determine the most effective regional anesthesia technique for improving postoperative pain management in patients undergoing PCNL.

Interventions

PROCEDURE

Erector Spinae Plane Block

Ultrasound-guided erector spinae plane block performed with local anesthetic in addition to standard general anesthesia for percutaneous nephrolithotomy.

PROCEDURE

Dual External Oblique Fascial Plane Block

Ultrasound-guided dual-approach (lateral and costal) external oblique fascial plane block performed using local anesthetic in addition to standard general anesthesia for percutaneous nephrolithotomy.

PROCEDURE

General Anesthesia

Routine general anesthesia according to institutional standard anesthetic and analgesic protocol without the addition of any regional anesthesia technique.
