经尿道前列腺剜除术切除腺体与术前预测前列腺重量的统计学关系

The statistic logic of the Gland Resected by Transurethral Enucleation of the Prostate and Predicted Preoperatively

目的:探讨经尿道前列腺剜除术(TUEP)切除的前列腺腺体与术前经直肠前列腺超声(TRUS)预测的前列腺总重量及内腺重量的统计学关系,以指导预期切除腺体的大小,减少前列腺电切术中腺体的残留。方法:由同一术者完成的微创经尿道前列腺剜除术71例,回顾性分析该组病例术前TRUS预测的前列腺总重量、内腺重量及术后切除腺体的重量,比较三者之间的统计学关系。结果:TRUS预测的前列腺总重量与切除腺体的重量具有正相关性(r=0.949,F=277.936,P=0.000);TRUS预测的前列腺内腺重量与切除腺体重量的差异无统计学意义(P>0.05);TRUS预测的前列腺总重量越大,切除腺体比例也越大(r=0.510,F=10.893,P=0.002)。结论:TRUS能良好的预测TUEP术中切除腺体的大小,当切除腺体明显少于预期值时可能存在腺体残留,术前发现前列腺巨大时需做好充分的术前准备,并高度重视并发症的发生。

Objective:To explore the statistic logic of the gland rectered by transurethral enucleation of the prostate(TUEP)and predicted by transrectal ultrasonography(TRUS)preoperatively.Aim to predict the weight of resected gland and reduce the omitted gland during the operation.Methods:From January 1,2013 to January 31,2014 the minimally invasive completed by the same surgeon after 71 cases of transurethral enucleation of the prostate.The gland weight resected by TUEP and gross or inner gland weight by preoperative TRUS were analyized retrospectively.The statistic logic of them would be presented.Results:There was a positive correlation between the weight of prostate predicted by TRUS and that was resected by TUEP(r=0.949,F=277.936,P= 0.000).The weight of inner gland predicted and gland resected were not significantly different(P>0.05).The prostate predicted by TRUS was large,the proportion of resected gland was greater correspondently(r=0.510,F=10.893,P=0.002).Conclusion:The resected gland by TUEP can be predicted with the help of preoperative TRUS.If the gland resected is less than the expected weight significantly,there is probable omitted gland.Preoperative preparation and prevention for the complication are necessary when the prostate is large by prediction.
