ABSTRACT
OBJECTIVE: To compare the safety and effectiveness of shovel-shaped electrode transurethral plasmakinetic enucleation of the prostate (PKEP) with those of plasmakinetic resection of the prostate (PKRP) in the treatment of benign prostatic hyperplasia (BPH). METHODS: We retrospectively analyzed the clinical data about 78 BPH patients received in Shanghai Ninth People's Hospital from June 2016 to January 2017, 39 treated by shovel-shaped electrode PKEP and the other 39 by PKRP. We observed the patients for 6 months postoperatively and compared the effects and safety of the two surgical strategies. RESULTS: No statistically significant difference was observed between the PKEP and PKRP groups in the operation time (ï¼»69.3 ± 8.8ï¼½ vs ï¼»72.2 ± 7.9ï¼½ min, P = 0.126), but the former, as compared with the latter, showed a markedly less postoperative loss of hemoglobin (ï¼»3.9 ± 2.8ï¼½ vs ï¼»13.9 ± 5.2ï¼½ g/L, P <0.001) and shorter bladder irrigation time (ï¼»12.5 ± 1.2ï¼½ vs ï¼»43.4 ± 2.8ï¼½ h, P <0.001), catheterization time (ï¼»64.0 ± 4.5ï¼½ vs ï¼»84.8 ± 3.0ï¼½ h, P <0.001) and hospital stay (ï¼»3.1 ± 0.3ï¼½ vs ï¼»5.5 ± 0.4ï¼½ d, P <0.001). There were no statistically significant differences between the PKEP and PKRP groups in the postoperative maximum urinary flow rate (Qmax) (ï¼»21.62 ± 1.07ï¼½ vs ï¼»21.03 ± 0.96ï¼½ ml/s, P = 0.12), International Prostate Symptoms Score (IPSS) (5.85 ± 0.90 vs 6.03 ± 0.81, P = 0.279), quality of life score (QoL) (2.0 ± 0.73 vs 2.28 ± 0.72, P = 0.09), postvoid residual urine volume (PVR) (ï¼»19.59 ± 6.01ï¼½ vs ï¼»20.21 ± 5.16ï¼½ ml, P = 0.629), or the incidence rates of urinary incontinence (2.56% ï¼»1/39ï¼½ vs 7.69% ï¼»3/39ï¼½, P >0.05) and other postoperative complications. CONCLUSIONS: Both PKEP and PKRP are effective methods for the treatment of BPH, but PKEP is worthier of clinical recommendation for a better safety profile, more thorough removal of the prostate tissue, less blood loss, shorter hospital stay, and better improved quality of life of the patient.
