目的:我们通过系统评价和荟萃分析评估了一些预测因素的有效性,这些预测因素可以通过非对比计算机断层扫描测量并可能影响ESWL的成功率。
方法:截至2022年4月,对所有数据源进行了广泛调查。从相关研究中提取数据,并使用RevMan软件进行分析。在随机效应模型中,标准平均差(SMD)和风险比(RR)值以95%置信区间给出.
结果:总计,汇总分析包括43项研究中的7148例患者.综合效应估计显示ESWL成功和ESWL失败组之间在Hounsfield单位(HU)方面存在显着差异,Hounsfield密度(HD),皮肤到石头的距离(SSD),输尿管壁厚度(UWT),石头体积,石块面积,腹部脂肪参数,输尿管近端直径,和肾积水.然而,在研究组之间未发现肾周绞合和肾皮质厚度具有统计学意义。
结论:HU,HD,SSD,UWT,石头体积,石块面积,腹部脂肪参数,输尿管近端直径和肾积水是预测ESWL成功的有效因素。对于ESWL的直径合适的结石,在手术前决定治疗是很重要的。
OBJECTIVE: We assessed the efficacy of some predictive factors that can be measured with non-contrast computed tomography and may affect ESWL success with a systematic
review and meta-analysis.
METHODS: All data sources were broadly investigated up to April 2022. Data were extracted from the relevant studies and analyzed with RevMan software. In a random effects model, standard mean difference (SMD) and risk ratio (RR) values were given with 95% confidence intervals.
RESULTS: In total, pooled analysis included 7148 patients in 43 studies. The combined effect estimate showed significant differences between the ESWL success and ESWL failure groups in terms of Hounsfield unit (HU), Hounsfield density (HD), skin to stone distance (SSD), ureteral wall thickness (UWT), stone volume, stone area, abdominal fat parameters, diameter of proximal ureter, and hydronephrosis. However, perinephric stranding and renal cortical thickness were not found to be statistically significant between the study groups.
CONCLUSIONS: HU, HD, SSD, UWT, stone volume, stone area, abdominal fat parameters, diameter of proximal ureter and hydronephrosis are effective factors for prediction of ESWL success. It is important to decide on treatment before the procedure for stones with appropriate diameter for ESWL.
