ABSTRACT
Objective To investigate the influence of transurethral plasmakinetic resection of the prostate(PKRP)on sexual function. Methods From January 2007 to December 2007.165 patients received PKRP,who had sexual active and completed the follow-up data forms before and after surgery.The average age of this cohort was 71 years(from 55 to 79 years).The average history of disease was 5.5(3-15)years while the average prostate volume 57(33-82)g,IPSS(26.4±2.6),quality of lire score(5.54±0.50),the maximum flow rate(7.04±4.10)ml/s,the average residual 120(55～250)ml.45 cases were complicated with urinary retention,and bladder stones 45 cases.15 cases with prostate stones.Their sexual function was assessed by the international index of erectile function,ejaculation function and sexual satisfaction before and 6 months after surgery by questionnaires,and compared the respective scores using SPSS14.0 and χ2 test. Results All of 165 patients,the IIEF-5 improved from(23.4±4.7)point to(24.1±4.9)point 6 months after operation(P>0.05),there was not significant.The abnormal ejaculation rate increased from 18.8%(31/165 patients)to 75.2%(124/165 patients)(P<0.001)after PKRP,respectively.The retrograde ejaculation rate increased from 11.6% (19/165 patients) to 64.2%(106/165 patients) after PKRP, respectively.There was a significant difference.128 patients (77.6 % ) and 132 patients (80.0 % ) were satisfied with their sexual active before and after 6 months PKRP, respectively. Conclusions The results of this study confirmed that PKRP has no negative influence on the quality of erections measured by IIEF-5.The loss of ejaculatory function has no influence on patients sexual active.
