Abstract: objective: To compare the efficacy of Memokath transurethal spiral thermo-expandable prostatic stent implantation and transurethral partial prostate resection for elderly patients with benign prostatic hyperplasia. Methods Retrospective analysis of the clinical data and treatment effect of 25 patients with BPH who were older than 75 years old in the Department of Urology, Xuzhou Medical University Hospital from May 2017 to October 2018, including 10 cases of prostate stent group, transurethral Plasma kinetic resection of prostate(PKRP) 15 cases. The operation time and hospitalization time of the two groups were compared. The international prostate symptom score (IPSS), maximum urinary flow rate (Qmax), residual urine volume (RUV), pain score (VAS), and quality of life (QOL) were measured before surgery and postoperative 3 and 12 months. Postoperative complications were collected. Result All patients were able to resume spontaneous urination after surgery, and the stent group was in operation time (30.3±6.9) min vs. (92.0±27.3)min and hospitalization time (3.2 ± 1.1) d vs. (7.3 ± 1.9) d were significantly shorter and the VAS was lower (2.8 ± 0.6) vs. (4.2 ± 1.2), The Qmax was more obvious in the stent group after 3 months of operation (13.7±1.9) ml·s-1vs (15.2±1.6) ml·s-1, and the improvement of IPSS, RUV and QOL was similar, and there was no statistical difference. The Qmax, RUV and IPSS of the stent group were significantly improved after the follow-up of the first year (P<0.05). There were no serious complications such as prostate resection syndrome and stent displacement in the two groups
