Comparative Study of the Effectiveness and Safety of Transurethral Bipolar Plasmakinetic Enucleation of the Prostate and Transurethral Bipolar Plasmakinetic Resection of the Prostate for Massive Benign Prostate Hyperplasia (>80 ml)

BACKGROUND: The aim of this study was to compare the clinical safety and effectiveness of transurethral bipolar plasmakinetic enucleation of the prostate (PKEP) vs. transurethral bipolar plasmakinetic resection of the prostate (PKRP) in the treatment of benign prostate hyperplasia (BPH) more than 80 ml. MATERIAL/METHODS: From June 2015 to February 2019, 179 BPH patients with prostate volume greater than 80 ml were enrolled and separated into a PKEP (n=81) group and a PKRP group (n=98). The patients in the 2 groups were followed up for 6 months. We collected and analyzed data from the international Prostate Symptom Score (IPSS), residual urine volume (RUV), quality of life (QOL), maximum urine flow rate (Qmax), and international erectile function index (ILEF-5). The clinical data collected during and after the operation and surgical complications were compared between the 2 groups. RESULTS: The PKEP group had significantly shorter operation time, bladder flushing time, indwelling catheter time, and hospitalization time, and has less intraoperative blood loss, intraoperative blood transfusion, postoperative secondary hemorrhage, bladder neck contracture, capsule perforation, and retrograde ejaculation (P<0.05). Compared with the PKRP group, the postoperative IPSS and QOL scores were significantly lower in the PKEP group (P<0.05), while the excision glandular tissue weight and Qmax were significantly improved (P<0.05). There were no significant differences in ILEF-5 scores, RUV, urethral stricture, urinary incontinence, or erectile dysfunction between the 2 groups (p>0.05). CONCLUSIONS: PKEP treatment of BPH with a large volume (>80 ml) has the advantages of complete gland resection, good surgical effect, improved surgical safety, and reduced intraoperative and postoperative complications.
