Objective: To compare the efficacy and safety of plasmakinetic enucleation (PKEP) with that of bipolar plasmakinetic resection of the prostate (PKRP) for benign prostatic hyperplasia (BPH). Background: PKEP has been reported to be a safe and effective method for the endoscopic management of BPH. Materials and Methods: A total of 303 patients with lower-urinary tract symptoms associated with BPH were included in this study. Of these, 143 patients underwent PKRP and 160 underwent PKEP. All patients were assessed preoperatively and evaluated at 3 months following surgery. International prostate symptom score(IPSS), quality of life (QOL), post void residual urine volume (PVRU) and maximum ?ow rate (Qmax) were obtained at the follow-up. The perioperative data and postoperative outcomes were compared. All complications were recorded. Results: There were no signi?cant differences between the two surgical groups preoperatively. The mean prostate volumes in the PKRP and PKEP groups were 75.6 cm3 and 77.3 cm3, respectively. Both groups were similar with respect to operation time, resected tissue weight, catheterization time and the total length of hospital stay. The blood loss observed in the PKEP group was significantly less than that of conventional PKRP (P<0.0001). PKEP was signi?cantly superior to PKRP in terms of the transient incontinence in the postoperative period (P=0.03). There were significant improvements of IPSS, QOL, Qmax and PVRU values at the postoperative assessment compared with baseline in either group. However, no statistically significant differences were identified between them. Conclusions: PKEP is a safe and effective method for the endoscopic management of BPH. Compared with PKRP, the main advantage of PKEP is the decreased risk of blood loss and transient incontinence.
