目的:分析比较经尿道双极等离子腔内前列腺剜除术(PKERP)与经尿道前列腺等离子双极电切术(PKRP)在治疗中重度BPH时的组织切除重量和切除率,评价两种手术方式的组织切除率差别及PKERP的术后临床效果。方法:随机对照研究2011年1~12月采用PKERP及PKRP治疗84例腺体重量超过50g的BPH患者临床资料,对术前B超所测前列腺体积后的估计重量、实际切除重量及手术腺体切除率进行对比分析。结果:84例患者无死亡发生,PKERP术前前列腺估测重量为50.2~135g,平均为79.4g;切除组织重量为43.6~112g,平均为60.7g,平均切除比率为76.5%。PKRP术前前列腺估测重量为52.2~130.2g,平均为77.6g;切除组织重量为28.7~78.1g,平均为38.1g,平均切除比率为54.5%。结果显示切除率与前列腺的估测重量呈正相关。两组患者术前前列腺估测重量比较,差异均无统计学意义(P>0.05);两组患者前列腺切除重量及前列腺组织切除率比较,差异均有统计学意义(P<0.05)。结论:PKERP治疗中重度BPH临床效果显著,并发症低,可以完整切除增生腺体,降低了腺体残留引发的继发性出血和再手术率。
OBJECTIVE: To compare the weight of tissue resection and resection rate of moderate to severe BPH treated with transurethral bipolar plasmaphoton scopy (PKERP) and transurethral prostate plasma bipolar resection (PKRP) The difference of tissue resection rate and the postoperative clinical effect of PKERP. Methods: A randomized controlled study of PKERP and PKRP from January 2011 to December 2011 treated 84 patients with BPH in patients with glandular weight more than 50g. The preoperative B-measured prostate volume after the estimated weight, the actual removal of the weight and surgical glands Resection rate for comparative analysis. Results: There was no death in 84 patients. The preoperative prostate weight of PKERP was estimated to be 50.2-135g with an average of 79.4g. The weight of the resected tissue was 43.6-112g with an average of 60.7g and the average resection rate was 76.5%. The estimated prostate weight before PKRP was 52.2-130.2 g, with an average of 77.6 g; the resected tissue weight was 28.7-78.1 g with an average of 38.1 g and the average resection rate was 54.5%. The results showed a positive correlation between resection rate and estimated prostate weight. There was no significant difference between the two groups in preoperative prostate gland weight estimation (P> 0.05). There was significant difference between the two groups in prostate gland weight and prostate gland resection rate (P <0.05). Conclusion: The clinical effect of PKERP in the treatment of moderate-severe BPH is significant, with low complication, complete removal of proliferating glands and reduction of secondary bleeding and reoperation rates caused by residual glands.
