Quadroiliac Plane Block for Pain Relief After Kidney Transplant

Official title: Analgesic Efficacy of Ultrasound-Guided Quadroiliac Plane Block Versus Surgical Wound Infiltration in Patients Undergoing Renal Transplantation: A Prospective, Randomized, Double-Blind, Controlled Clinical Trial

Run by Kanuni Sultan Suleyman Training and Research Hospital · NCT07716566 · Data updated 2026-11-12

This trial tests whether an ultrasound-guided unilateral quadroiliac plane block can reduce pain and opioid use after kidney transplant compared with standard surgical wound infiltration.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–80 undergoing renal transplantation with ASA I–III who can consent.

Probably not a fit

Patients with contraindications to regional anesthesia or local anesthetic allergy may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, randomized, double-blind study in adults undergoing renal transplantation. Participants are assigned to receive either a unilateral quadroiliac plane block with 40 mL of 0.25% bupivacaine or surgical wound infiltration with 10 mL of 0.25% bupivacaine. The procedure is performed under anesthesia and outcomes are assessed postoperatively by investigators blinded to group assignment. The aim is to determine if the nerve block provides superior analgesia and reduces opioid requirements. Treatment allocation is concealed and handled by study personnel not involved in outcome assessment.

Why it matters

Potential benefit: If successful, the block could provide better pain control and lower opioid needs after kidney transplant.

How similar studies have gone: Local anesthetic plane blocks in abdominal surgery have shown analgesic benefits in prior studies; this trial extends that approach to renal transplantation.
