Therapeutic Effects of Press Needle on 5-D Pruritus Scale in Hemodialysis Patients With Chronic Kidney Disease-Associated Pruritus

The goal of this clinical trial is to assess whether press needle acupuncture (PN) is more effective than sham press needle (sham PN) in reducing pruritus in patients with chronic kidney disease-associated pruritus (CKDaP) undergoing hemodialysis. The main questions it aims to answer are: * Does PN, compared to sham PN, reduce pruritus severity as measured by 5-D Pruritus Scale after the 2nd, 4th, 6th, and 8th therapy sessions? * Does PN, compared to sham PN, maintain a superior reduction in pruritus severity four weeks after the final session? * Are there any side effects associated with PN or sham PN in CKDaP patients on hemodialysis? Participants will: * Be patients undergoing hemodialysis with confirmed CKDaP * Undergo cognitive screening with MMSE to ensure accurate self-reporting * Be randomly assigned to receive either PN (needle inserted) or sham PN (tape only) * Have PN or sham PN applied unilaterally to acupoints LI11, SP10, ST36, and SP6, replaced every 3-4 days over a 4-week period * Complete the 5-D Pruritus Scale questionnaire before intervention, after every 2 sessions (2nd, 4th, 6th, 8th), and 4 weeks post-treatment
