【摘要】 目的:探討经尿道钬激光膀胱肿瘤剜除术与电切术治疗浅表性肿瘤的效果。方法:选取2016年5月-2017年5月本院收治的浅表性膀胱肿瘤患者58例。按照随机数字表法将其分为研究组和对照组,各29例。对照组应用经尿道电切术治疗,研究组应用经尿道钬激光剜除术治疗。比较两组术中出血量、膀胱冲洗时间、尿管置留时间、住院时长、术后1年肿瘤预后标志物情况(P53蛋白和KI-67蛋白)、相关并发症发生情况。结果:研究组术中出血量、膀胱冲洗时间、尿管留置时间、住院总时长均少于对照组,比较差异均有统计学意义(P<0.05);研究组P53、KI-67蛋白阴性率分别为82.76%、89.66%,均高于对照组的48.28%、37.93%,比较差异均有统计学意义(P<0.05);研究组并发症发生率为0,低于对照组的17.24%(P<0.05)。结论:经尿道钬激光膀胱肿瘤剜除术治疗浅表性膀胱肿瘤操作简单,疗效显著,与电切术比较,更具有优越性,可作为治疗该肿瘤的可行性途径之一,对患者而言提高治疗效果和术后满意度具有重要意义,因此建议在临床上进一步推广应用。

【Abstract】 Objective:To investigate the curative effect of transurethral holmium laser enucleation of bladder tumors and electrocision in treatment of superficial tumors.Method:A total of 58 patients with superficial bladder tumors admitted to our hospital from May 2016 to May 2017 were selected.According to the random number table method,they were divided into study group and control group,29 cases in each group.The control group was treated with transurethral electrotomy,and study group was treated with transurethral holmium laser enucleation.The intraoperative bleeding volume,bladder irrigation time,indwelling time of urinary catheter,length of hospitalization,prognostic markers(P53 protein and KI-67 protein)of 1 year after operation and related complications between two groups were compared.Result:The intraoperative bleeding volume,bladder irrigation time,indwelling time of urinary catheter,length of hospitalization in study group were less than those of control group,the differences were statistically significant(P<0.05).The negative rates of P53 and KI-67 protein in study group were 82.76% and 89.66% respectively,which were higher than 48.28% and 37.93% in control group,the differences were statistically significant(P<0.05).The incidence of complications in study group was 0,which was lower than 17.24% in control group(P<0.05).Conclusion:Transurethral holmium laser enucleation of bladder tumors for superficial bladder tumors is simple and effective.Compared with electrotomy,it has more advantages and can be used as one of the feasible ways to treat this tumor.It is important for patients to improve the curative effect and satisfaction after operation.Therefore,it is suggested to further promote the clinical application.

在本研究中所提及的肿瘤预后标志物P53蛋白和KI-67蛋白,与肿瘤患者预后(预测可能病程和结果)有着密切关系,在术后预测关于病情复发率有着重要的研究价值[16]。其中,KI-67蛋白是一种增殖细胞核蛋白,与细胞周期关系密切,因此能有效反映出细胞增殖活跃程度,并且对于患者预后恢复情况和浸润转移具有重要意义[17]。而P53是一种抑癌基因,与膀胱癌的临床分期、病理分级、患者预后有着密切关系[18]。KI-67蛋白和P53蛋白均能作为浅表性膀胱肿瘤患者预后的重要指标。本研究结果显示,研究组P53、KI-67蛋白阴性率分别为82.76%、89.66%,均高于对照组的48.28%、37.93%,比较差异均有统计学意义(P<0.05);而且研究组术中出血量、膀胱冲洗时间、尿管留置时间、住院总时长均少于对照组,比较差异均有统计学意义(P<0.05)。提示经尿道钬激光膀胱肿瘤剜除术的效果优于电切术。

本次研究虽然取得了一定的成果,证实了经尿道钬激光膀胱肿瘤剜除术在治疗浅表性膀胱肿瘤中存在可行性和有效性,能够有效降低患者术后复发率、相关并发症发生率,但是依旧缺少长期的、有效的、大样本多中心的实验记录和数据[19]。因此对于部分结论仍存在讨论的必要性,所以将目光放在更长远的角度来看,待扩大数据样本后,可将其作为重点研究对象进行深入探讨,以求获得更加科学严谨的实验结果[20]。

综上所述,与电切术相比,经尿道钬激光膀胱肿瘤剜除术治疗浅表性膀胱肿瘤操作方式简单且效果显著,在临床中具有较高的应用价值,因此可将此种手术方式作为有效治疗浅表性膀胱肿瘤的方式之一,建议在临床上推广应用。
