Objective:To investigate the efficacy of transurethral bipolar plasmakinetic enucleation of prostate (PKEP) in treatment of benign prostate hyperplasia complicated with bladder stones and its influence on sexual function. Methods:116 cases of benign BPH patients complicated with bladder stones admitted to Guihang Pingba County Hospital and Guihang Anshun County Hospital from January 2009 to December 2016 were randomly divided into observation group and control group,58 cases in each group. The observation group was treated with PKEP, the control group was treated with transurethral bipolar plasmakinetic resection of prostate (PKRP). The basic situation of surgery and postoperative complications were compared between the two groups. The scores of International Prostate Symptomscore (IPSS) and Quality of Life (QOL) were evaluated before operationand at 6th months after surgery, the post void residual volume (PVR), maximum fflow rate (Qmax) and sexual function indicators[International Erectile Dysfunction Index-5 Questionnaire (ⅡEF-5) score, retrograde ejaculation (RE) and erectile dysfunction (ED) incidence] were evaluated and compared. Results:There was no significant difference in the lithotripsy time of bladder stones between the two groups (P>0.05),while the time of prostatectomy, intraoperative bleeding, postoperative bladder irrigation time, urinary catheter retention time and hospital stay in the observation group were significantly lower than those in the control group (P<0.05). The postoperative incidences of temporary incontinence, bladder spasms, bladder irritation in the observation group were significantly lower than the control group (P<0.05).There were no significant differences in IPSS score, PVR and Qmax between the two groups at 6th month after operation (P>0.05),while the QOL score in the observation group was significantly lower than that in the control group (P<0.05),the ⅡEF-5 score in the observation group was significantly higher than that in the control group (P<0.05).The incidence of ED and RE was 8.62% and 25.86% in the observation group, significantly lower than 25.86% and 48.28% in the control group, the difference was statistically significant (P<0.05). Conclusion:PKEP for the treatment of benign BPH with bladder stones is safe and effective with the advantages of minimal invasion, quick recovery and fewer complications, which has less disruption of sexual function.
