Abstract:
Objective:To assess the feasibility and efficacy of transperineal laser ablation(TPLA)with single laser fiber in treating benign prostatic obstruction(BPO).Methods:From April 2021 to March 2024,a total of 13 BPO patients were selected from Beijing Friendship Hospital.TPLA was performed using a single laser fiber,which was guided by transrectal biplane ultrasound.The single laser fiber was used to undergo TPLA under the guidance of trans-rectal dual-plane ultrasound.The intraoperative time,ablation time,energy consumption,indwelling time of catheter,and complications were observed.The postoperative 6 months was chosen as the cut-off point of follow-up,and the pre and postoperative changes of international prostate symptom score(IPSS),quality of life index(QoL),prostate volume(PV),residual urine volume(RUV)and the maximum urine flow rate(Qmax)were compared.Results:All 13 patients successfully underwent TPLA with single laser fiber.The average operation time was(55.1±18.3)min,and the average ablation time was(16.3±1.7)min,and average energy consumption was(3951.6±459.7)J,and the median value of indwelling time of catheter was 7(7,10)days.The number of postoperative complication was 2 cases,and both them belonged to Clavien-Dindo grade II complication.At the postoperative 6th month,the IPSS,QoL,PV,Qmax and RUV of all patients were improved,all of which were better than preoperative these indicators,and the differences were significant(t=12.102,-3.228,-3.181,-2.581,-2.936,P<0.05).Conclusion:The application of single laser fiber in conducting TPLA operation is feasibility at technical aspect,and it can achieve the therapeutic goals of improving patients'symptoms and enhancing their quality of life.Although its operational time is slightly longer than that of using multiple fibers simultaneously,it can effectively reduce the cost of expenditure for consumables.
