Background Benign prostatic hyperplasia (BPH) is a common disease in elderly males, and many kinds of minimally invasive procedures can be used for the treatment of BPH. However, various procedures have caused some controversies regarding clinical outcomes, so more studies are needed to validate these controversial topics. Aims This study aimed to explore differences of clinical efficacy, surgical features, and complications between transurethral resection of the prostate (TURP) and plasmakinetic enucleation of the prostate (PKEP) for BPH. Methods A total of eligible 850 cases of BPH underwent TURP (the TURP group, 320 cases) or PKEP (the PKEP group, 530 cases) in the urology department of our hospital from March 2015 to 2018 were involved in this study. Then, the baseline data, surgical characteristics, IPSS, QoL, PVR, Qmax, IIEF-5, and documented complications were compared between the two groups. Results The operative time, intraoperative irrigation volume, postoperative hemoglobin, decrease in hemoglobin, postoperative irrigation time and volume, catheterization time, and hospital stay of the PKEP group were significantly less than those of the TURP group (all P < 0.05). At 3 months, 1, 2, and 3 years after operation, no significant differences were observed in IPSS, QoL, PVR, but the results of Qmax and IIEF-5 in the PKEP group were significantly higher than those parameters in the TURP group (all P < 0.05). The incidences of massive blood loss, postoperative secondary bleeding, blood transfusion, capsular perforation, urinary tract irritation, bladder spasm, clot retention, urinary tract infection, transient incontinence, erectile dysfunction, and the incidences of II, III grade of Clavien–Dindo classification in the PKEP group were significantly lower than those of the TURP group (all P < 0.05). Conclusion The clinical efficacy of PKEP is compared favorably with TURP during midterm follow-up. Given the merits such as less blood loss and hospital stay, lower complications, PKEP should be given a priority for BPH.
