Blood Loss Comparison Of Transurethral Plasmakinetic Resection Versus Monoploar Transurethral Resection Of The Prostate

Objective:To compare blood loss between transurethral plasmakinetic resection of prostate and monoploar transurethral resection of the prostate.Furthermore,to investigate the effective treatment approach between PKRP and TURP by the blood loss comparison.Method:From October 2007 to March 2008,30 cases of patients with BPH underwent transurethral plasmakinetic resection of the prostate(PKRP);While from April to July 2008,30 cases of patients with BPH underwent ordinary transurethral resection (TURP).Each patient either in PKRP group or in TURP group was not selected.The data of these 60 patients was analyzed.In PKRP group,age ranging from 63 to 89 years,on average(74.2±7.0) years,mean prostate volume was(49.3±33.1) ml;In TURP group,age ranging from 57 to 89 years,on average(73.3±7.2) years,mean prostate volume was(51.1±23.2) ml.Before the operation hemoglobin concentration of the blood were measured in all patients.All infused fluid during the operation were collect.The volume and hemoglobin concentration of the fluid were measured exactly. The bleeding during the operation were calculated with the formula V(ml)= 1000×ρ1×V1/ρ(ρ=hemoglobin concentration of the blood before operation;ρ1= hemoglobin concentration of the fluid;V1=volume of the fluid).The weight of the resected tissue were measured exactly.Results:In PKRP group,the average time of operation was(111.3±42.5) min;mean weight of resected tissue was(20.1±14.3) g;Mean blood loss was(86.3±79.9) ml; Mean blood loss per gram of prostate resected was(3.7±1.9) ml/g;Mean decrease of hemoglobin concentration was(11.2±8.7) g/l;Mean decrease of erythrocrit was (3.1±2.3).In TURP group,the average time of operation was(108.0±42.2) min;mean weight of resected tissue was(23.6±13.1) g;Mean blood loss was(201.8±178.7) ml; Mean blood loss per gram of prostate resected was(8.3±6.1) ml/g;Mean decrease of hemoglobin concentration was(16.0±9.6) g/l;Mean decrease of erythrocrit was (4.9±3.2).The difference has no statistic significant in weight of resected tissue and the average time of operation between PKRP and TURP(p＞0.05).The blood loss of PKRP was significantly less than that of TURP(p＜0.005).The blood loss per gram of prostate resected of PKRP was significantly less than that of TURP(p＜0.001).The decrease of hemoglobin concentration and erythrocrit were less that that of TURP(P＜0.05).Conclusion:The blood loss of transurethral plasmakinetic resection of the prostate is significantly less than that of monopolar transurethral resection.Although TURP is still considered the standard for the surgical treatment of symptomatic BPH,the morbidity associated with the procedure is still debated.PKRP has well hemostasia, clear view,using normal saline irrigation,reducing TUR syndrome,less conductive trauma,more safety,less disturbance to organism,fewer complications and easy to be controlled.It is a better treatment option for BPH.
