经尿道前列腺等离子双极电切术与普通电切术中失血量比较

目的比较经尿道前列腺等离子双极电切术与普通电切术中失血量。方法自2007年10月至2008年3月，收治的30例BPH患者行经尿道等离子双极电切（PKRP）；自2008年4月至7月，收治的30例BPH患者行普通电切（TURP）。分析这60例患者的临床资料。PKRP组年龄（74．2±7．0）岁，前列腺体积（49．3±33．1）ml；TURP组年龄（73．2±7．2）岁，前列腺体积（51．1±23．2）ml。收集术中所有冲洗液，测冲洗液体积，混匀后精确测血红蛋白浓度。结果PKRP组手术时间（111．3±42．5）min，切除前列腺组织重量（20．1±14．3）g，失血量（86．3±79．9）ml，每克前列腺组织平均失血量（3．7±1．9）ml／g；TURP组手术时间（108．0±42．2）min，切除前列腺组织重量（23．6±13．1）g，失血量（201．8±178．7）ml，每克前列腺组织平均失血量（8．3±6．1）ml／g。PKRP组和TURP组手术时间及切除前列腺组织重量差异无统计学意义（P〉0．05）。PKRP组术中失血量少于TURP组（P〈0．01）。PKRP组每克前列腺组织平均失血量少于TURP组（P〈0．01）。结论经尿道前列腺等离子双极电切术中失血量少于普通电协。

Blood loss comparison of transurethral plasmakinetic resection versus conventional transurethral resection of the prostate

Objective To compare blood loss between transurethral plasmakinetic resection of prostate （PKRP） and conventional transurethral resection of the prostate （TURP）. Methods From October 2007 to April 2008, 30 cases of patient with BPH underwent PKRP; While from May to July 2008, 30 cases of patient with BPH underwent TUP,.P. Each patient either in PKRP group or in TURP group was not selected. The data of these 60 patients was analyzed. In PKRP group, mean age was （74.2 ± 7.0） years, mean prostate volume was （49.3 ± 33.1）ml; In TURP group, mean age was （73.3±7.2）years, mean prostate volume was （51.1 ±23.2）ml. All infused fluid during the operation was collected. The volume and hemoglobin concentration of the fluid were measured exactly. Results The difference has no statistic significant in weight of resected tissue （20.1±14.3 g VS 23.6±13.1 g） and the average time of operation （111.3±42.5 rain VS 108.0±42.2 min） between PKRP and TURP （P 〉0.05）. The blood loss of PKRP was significantly less than that of TURP （86.3±79.9 ml VS 201.8±178.7 ml, P 〈0.005）. The blood loss per gram of prostate resected of PKRP was significantly less than that of TURP （3.7±1.9 ml/g VS 8.3±6.1 ml/g, P 〈0.001）. Conclusion The blood loss of PKRP is significantly less than that of conventional TURP.
