Abstract:
Objective To evaluate the techniques and efficacy of artery embolization in the treatment of benign prostatic hyperplasia(BHP).Methods This study included 12 patients(age range,61-82 years) who were diagnosed to have BHP by clinical manifestations,CT and B-ultrasound,with the disease course of 2-16 years.The relevant parameters were as follows:mean residual urine(RU) of 138 ml,Qmax of 9.6 ml/s,mean IPSS of 24.2 and QOL of 4.8.In these patients,the prostate blood-supply arteries were confirmed by super-selective arteriography,and were embolized by injection of PVA and Gelfoam via artery catheters.The pre-and post-operative IPSS,QOL,Qmax and RU were compared.Meanwhile the changes of prostate volume and blood supply were evaluated by CT and B-ultrasound.In addition,the change of urethral diameter was evaluated by urethrography.Results In the 12 patients,21 prostate blood-supply arteries were embolized,including 5 branches of internal iliac artery,9 branches of inferior vesical artery,5 branches of internal pudendal artery,2 branches of obturator artery.The arteries were embolized bilaterally in 9 patients and embolized unilaterally in 3 patients.Postoperatively,the mean IPSS was 4.8;QOL,1.3;Qmax,18.9 ml/s;RU,0-3 ml,which indicated that the urethral obstruction was obviously improved after operation.CT and B-ultrasound showed that the prostate volume was obviously decreased from 127 ml to 90 ml on average with a reduction rate of 71%,and the urethral stricture disappeared on X-ray examination.Color Doppler imaging showed that the blood supply inside the prostate was reduced.Conclusions The artery embolization for the treatment of BHP is a new method with several virtues of less trauma, marked effect,better safety and fewer complications.
