This randomized, double-blind controlled study aims to evaluate the effectiveness of thread implantation acupuncture at EX-B2 L1 in reducing postoperative pain and improving quality of life in patients undergoing laparoscopic living donor nephrectomy. Thirty-four participants will be randomly assigned to receive either thread implantation acupuncture with polydioxanone (PDO) thread at EX-B2 L1 plus standard postoperative therapy or sham thread implantation acupuncture without thread insertion plus the same standard therapy. Pain intensity will be assessed using the Visual Analogue Scale (VAS) and quality of life with the Short-Form 36 (SF-36). The study seeks to determine whether thread implantation acupuncture provides additional analgesic and quality-of-life benefits beyond standard postoperative care.
