不同手术方式治疗女性压力性尿失禁中长期疗效和并发症的网状Meta分析

背景女性压力性尿失禁(SUI)是一种泌尿外科常见疾病,给女性患者造成了巨大的生活及经济负担。SUI患者通常在保守治疗不理想时选择手术治疗,自Kelly术运用于治疗SUI后,多种新型术式相继发展并在疗效上取得了重大进展,目前仍缺乏新型术式之间中长期疗效及安全性的直接或间接比较。目的运用网状Meta分析比较经耻骨后尿道固定悬吊术(Burch)、经耻骨后无张力尿道中段吊带术(TVT)、由外向内经闭孔吊带术(TOT)、由内向外无张力尿道中段吊带术(TVT-O)、无张力经阴道尿道中段吊带术(TVT-S)、单切口可调节吊带术(Ajust)治疗女性SUI的有效性及安全性,筛选治疗SUI的最佳手术方式。方法基于计算机系统检索PubMed,the Cochrane Library,Medline,EMBase数据库中关于比较Burch、TVT、TOT、TVT-O、TVT-S、Ajust术式治疗SUI的随机对照试验(RCT),检索时间从建库至2018年7月。两名研究者对纳入的RCT进行数据提取及质量评价,提取信息包括:第一作者、发表时间、干预措施、样本量、年龄、随访时间和客观治愈率、主观治愈率、排尿困难、阴道黏膜穿孔、下尿路感染、吊带暴露、术后新发急迫症状/急迫性尿失禁、术后大腿疼痛/腹股沟疼痛。采用RevMan 5.3和Stata 14.0进行数据处理。结果共纳入42篇RCT,6065例患者。网状Meta分析结果显示,TOT客观治愈率低于TVT〔OR=0.96,95%CI(0.91,1.00),P<0.05〕;Ajust主观治愈率高于Burch、TOT、TVT-O、TVT-S〔OR=1.27,95%CI(1.01,1.61);OR=1.14,95%CI(1.01,1.27);OR=1.05,95%CI(1.00,1.10);OR=1.12,95%CI(1.04,1.22),P<0.05〕,TOT低于TVT〔OR=0.93,95%CI(0.86,1.00),P<0.05〕;TVT-O排尿困难发生率低于TVT〔OR=0.57,95%CI(0.34,0.95),P<0.05〕;TOT阴道黏膜穿孔发生率高于TVT〔OR=4.17,95%CI(1.37,12.74),P<0.05〕,TVT-O阴道黏膜穿孔发生率低于TOT〔OR=0.20,95%CI(0.06,0.66),P<0.05〕;TOT术后下尿路感染发生率低于TVT〔OR=0.62,95%CI(0.42,0.91),P<0.05〕;TVT-O术后大腿/腹股沟疼痛发生率高于Burch〔OR=12.89,95%CI(1.22,135.66),P<0.05〕,TOT、TVT-O术后大腿/腹股沟疼痛发生率高于TVT〔OR=2.37,95%CI(1.00,5.58);OR=3.07,95%CI(1.50,6.27),P<0.05〕,TVT-S、Ajust术后大腿/腹股沟疼痛发生率低于TVT-O〔OR=0.25,95%CI(0.10,0.63);OR=0.18,95%CI(0.04,0.84),P<0.05〕。曲线下面积(SUCRA)排序结果显示,在客观治愈率、吊带暴露和术后新发急迫症状/急迫性尿失禁方面,TVT效果较好;在主观治愈率、排尿困难、阴道黏膜穿孔方面,Ajust效果较好;在下尿路感染方面,TOT效果较好;在术后大腿疼痛/腹股沟疼痛方面,Burch效果较好。结论Ajust在治疗SUI的中长期研究中可能具有较好的疗效和安全性。

Characteristics of Phosphorous Adsorption and Desorption by Organo-Mineral Colloidal Complexes of Purple Paddy Soils

The kinetic characteristics of P adsorption and desorption by organo-mineral colloidal complexes (OMC)were studied using acid, calcareous and neutral purple paddy soils taken from Chongqing and Sichuan, China.The results showed that the P adsorption capacity of the organo-mineral colloidal complexes differed with the soil types, being higher for the acid and calcareous purple soils than for the neutral purple soils. Partial removal of the organic matter increased the adsorption capacity of the colloidal complexes. A very significant positive correlation was found between the amounts of P desorbed from OMC and the P saturation degrees.The P adsorption reaction was quick at the early stage and slowed later. The raise of temperature increased P adsorption capacity and P adsorption rate of the colloidal complexes. The adsorption processes could be described by the Elovich equation.
