J Urol:二次尿道成形术干预的预测因子调查

2021-12-25 AlexYang MedSci原创

评估了早期监测尿道镜检查结果和行尿道成形术患者的长期结果,从而确定尿道镜检查结果对手术失败的预测价值。

尿道成形术是治疗尿道狭窄疾病的金标准,与内窥镜技术相比,它的成功率更高,而且成本低。尿道狭窄疾病的成功治疗涉及保持管腔的通畅和患者的主观满意度情况。然而,尿道成形术后的"成功"定义还有争议。

术后监测中的尿道镜检查,是预测尿道成形术后一年内是否需要再次手术的有效工具

近期,来自美国的研究人员在《J Urol》杂志上发表文章,评估了早期监测尿道镜检查结果和行尿道成形术患者的长期结果,从而确定尿道镜检查结果对手术失败的预测价值

研究人员评估了在美国和加拿大的10家机构进行尿道成形术的304名患者,且随访至少进行4年。所有患者均使用柔性17Fr膀胱镜进行检查,并将患者分为三组:a.管腔正常;b.大口径狭窄(≥17Fr),定义为膀胱镜能够轻易通过狭窄处;c.小口径狭窄(<17Fr),定义为膀胱镜无法通过。失败指狭窄复发,需要进行二次干预。研究人员使用了STATA进行了数据统计学分析。

随访时间的中位数为64.4个月(范围为55.3-80.6),尿道成形术后首次监测的尿道镜检查时间为第3.7个月(范围为3.1-4.8)。结果发现,管腔正常的194人中有29人(15%)进行了二次干预手术,管腔大口径狭窄(≥17Fr)的60人中有11人(18.3%)进行了二次干预手术,管腔小口径狭窄(<17Fr)的50人中有32人(64%)进行了二次干预手术(P<0.001)。另外,对于管腔正常患者组,1年、3年和9年的累积干预概率分别为0.01、0.06和0.23;≥17Fr组为0.05、0.17和0.18;<17Fr腔组为0.32、0.50和0.73。患者报告的结果指标在区分三组患者方面表现不佳。

尿道整形术后,需要二次干预患者的复发性狭窄的特征

综上所述,尿道成形术后,早期膀胱镜观察到的使管腔变窄至<17Fr的疤痕复发,是最终接受二次干预患者的显著长期预测因素
