Clinical Study Of Transurethral Plasmakinetic Resection Of The Prostate Combine With Continuous Negative Pressure Suction For The Treatment Of Large Volume Benign Prostate Hyperplasia

Objective:To investigate the effect of continuous negative pressure suction on operation result and the related complications in transurethral plasmakinetic resection of the prostate(PKRP).Methods: Analyse the clinical records of 60 Large volume benign prostate hyperplasia(>80ml)patients for operations in the Urology of our hospital between Sep.2015 and Mar.2016.The patients were divided into two groups.30 of them were for PKRP with continuous negative pressure suction(experimental group): resectoscope outlet connected to continuous suction equipment during the operation.The negative pressure was limited between 0.02-0.05 MPa.The other 30 of the patients were only for PKRP(comparison group): the resectoscope was directly led outside.Both the two groups underwent conventional PKRP.Record the operation time,the weight of resected prostate tissue,amount of intraoperative hemorrhage,postoperative sodium levels,time of postoperative washing bladder,time of postoperative retention catheter,time of postoperative stay in hospital,complications and differences of Qmax,RUV,IPSS,QOL between pre-operation and post-operation.Results: All the 60 patients underwent RKPR successfully.The time and amount of intraoperative hemorrhage of experimental group was apparently less than comparison group,the difference is statistically significant(P<0.05);There was no statistically significant difference between the data of the weight of resected prostate tissue,time of postoperative washing bladder,time of postoperative retention catheter,time of postoperative stay in hospital(P>0.05).The postoperative RUV,IPSS and QOL were lower than those of pre-operation,while the Qmax apparently rose,the difference is statistically significant(P<0.05),and indicate that two groups of patients with postoperative micturate situation has improved significantly.However,there was no statistically significant difference of Qmax,RUV,IPSS,QOL changes between the two groups(P>0.05),and prove that the curative effect of two groups of postoperative improvement in the lower urinary tract symptoms were consistent.As to complications,there were no serious ones such as TURS,prostatic capsule perforation,transfusion and so on.The rate of postoperative bleeding and bladder spasm in experimental group were apparently lower than comparison group and there were statistically significant differences between them(P<0.05);however,there was no statistically significant difference of incidence rate of urethral stricture,temporary urinary incontinence and urinary tract infections between the two groups(P>0.05).Conclusions: Applying continuous negative pressure suction to transurethral plasmakinetic resection of the prostate(PKRP)can shorten the operation time and reduce intraoperative hemorrhage.It also can reduce the incidence rate of two complications—postoperative bleeding and bladder spasm.It makes operation safer and the method is simple and operable,which is suitable to spread and apply.
