Optimize the management of urological tube-related emergencies during the coronavirus disease 2019 (COVID-19) pandemic

BackgroundTo introduce and determine the value of optimized strategies for the management of urological tube-related emergencies with increased incidence, complexity and operational risk during the global spread of coronavirus disease 2019 (COVID-19).MethodsAll emergent urological patients at Tongji Hospital, Wuhan, during the period of January 23 (the beginning of lockdown in Wuhan) to March 23, 2020, and the corresponding period in 2019 were recruited to form this study’s COVID-19 group and control group, respectively. Tongji Hospital has the most concentrated and strongest Chinese medical teams to treat the largest number of severe COVID-19 patients. Patients in the control group were routinely treated, while patients in the COVID-19 group were managed following the optimized principles and strategies. The case incidence for each type of tube-related emergency was recorded. Baseline characteristics and management outcomes (surgery time, secondary complex operation rate, readmission rate, COVID-19 infection rate) were analyzed and compared across the control and COVID-19 periods.ResultsThe total emergent urological patients during the COVID-19 period was 42, whereas during the control period, it was 124. The incidence of tube-related emergencies increased from 53% to 88% (P<0.001) during the COVID-19 period. In particular, the incidence of nephrostomy tube-related (31% vs. 15%, P=0.027) and single-J stent-related problems (19% vs. 6%, P=0.009) increased significantly. The mean surgery times across the two periods were comparable. The number of secondary complex operations increased from 12 (18%) to 14 (38%) (P=0.028) during the COVID 19-period. The number of 2-week postoperative readmission decreased from 10 (15%) to 1 (3%) (P=0.049). No participants contracted during the COVID-19 period.ConclusionsUrological tube-related emergencies have been found to have a higher incidence and require more complicated and dangerous operations during the COVID-19 pandemic. However, the optimized management strategies introduced in this study are efficient, and safe for both urologists and patients.     

磁敏感加权成像黑质“燕尾征”在帕金森病中的诊断价值

目的:探讨3.0 T磁敏感加权成像(susceptibility weighted imaging,SWI)中"燕尾征"缺失在帕金森病(Parkinson's dis-ease,PD)的诊断价值并分析黑质小体-1 (nigrosome-1)可视化与PD患者临床资料的相关性.方法:收集2017年9月至2019年11月于重庆医科大学附属第一医院神经内科住院的50例PD患者及年龄、性别与之匹配的57例非PD患者.所有受试者均接受3.0 T头颅SWI检查.在获得的SWI图像上,由2名临床医师采用盲法独立对双侧"燕尾征"进行评估.一侧"燕尾征"缺失即判定为PD.计算"燕尾征"缺失诊断PD的灵敏度、特异度、预测值和准确度,并分析nigrosome-1可视化与PD患者临床资料的相关性.结果:以临床诊断作为金标准,45例PD患者判断正确,评估者之间的一致性很高(k=0.963,P=0.000)."燕尾征"缺失诊断PD的灵敏度为90.0％,特异度为91.2％,阳性预测值为90.0％,阴性预测值为91.2％,准确度为90.7％.44例PD患者临床症状不对称,其中32例患者nigrosome-1可视化不对称.PD患者nigrosome-1可视化偏侧和临床症状偏侧比较差异无统计学意义(x2=5.756,P=0.056).11例PD患者双侧nigrosome-1全部缺失,纳入全部缺失组,其余PD患者为非全部缺失组.全部缺失组和非全部缺失组患者的汉密尔顿抑郁量表评分差异有统计学意义(U=126.500,P=-0.038),而病程、帕金森病统一评定量表第Ⅲ部分、改良Hoehn-Yahr(H-Y)分级、简易智能状态量表和蒙特利尔认知评估量表评分差异均无统计学意义(P=0.768、0.140、0.839、0.054、0.067).结论:"燕尾征"缺失诊断PD的准确率较高,缺失程度可能与PD患者的抑郁程度有关,对PD的诊断有一定参考价值.     

超声引导下经皮肺穿刺活检术术后并发症分析

目的分析超声引导下经皮肺穿刺活检术术后并发症的相关影响因素。 方法收集2015年1月至2017年12月于西部战区总医院住院并在超声引导下行经皮肺穿刺活检术的205例患者临床资料，分析205例患者穿刺术后病理结果及并发症发生率，探讨超声引导下经皮肺穿刺活检术术后并发症的相关影响因素。 结果205例患者行超声引导下经皮肺穿刺活检术，术后并发出血8例，占3.9%(8/205)，术后发热3例，占1.46% (3/205)，为低热，且予以对症治疗后均恢复正常，无严重并发症发生。术后出血的发生率在不同性别、年龄、BMI及病灶类型的患者中无显著差异(P>0.05)，且吸烟对患者术后出血率也无显著影响(P>0.05)；但有基础疾病的患者其术后出血率更高(P＝0.005)，且病灶直径越小，术后越容易并发出血(P＝0.006)。不同性别、年龄及病灶类型对术后发热的发生率无显著影响(P>0.05)，且术后发热与吸烟史及基础疾病史无关(P>0.05)，但BMI≥24或3 cm ≤病灶直径(d)<6 cm的患者术后更易发热(P<0.05)。 结论超声引导下经皮肺穿刺活检术术后并发症发生率低(约为5.37%)，主要为出血及低热，其中术后出血主要与基础疾病史和病灶直径有关，术后发热主要与病灶直径及BMI有关。     

后腹腔镜肾根治性切除术中肾标本取出方法的探索

目的探讨一次性切口保护套在后腹腔镜肾根治性切除术中的应用及标本取出效率。方法回顾性分析本院2018年12月至2019年6月接受后腹腔镜肾根治性切除术的37例肾癌患者的临床资料。根据手术后标本取出体外的方法分为观察组(18例)和对照组(19例),观察组使用一次性切口保护套,对照组则使用传统自制标本袋;观察比较两组患者标本的取出时间和置入次数等指标。结果观察组与对照组的标本取出时间分别为(225.94±47.04)、(508.84±45.81)s,差异有统计学意义(P<0.05)。观察组中有17例患者标本一次性顺利取出,1例因肿瘤较大,取出困难,经延长切口后顺利取出,所有标本完整均未破裂;对照组中有17例患者标本一次性顺利取出,另外2例患者经适当延长切口后取出,所有标本完整均未破裂。两组置入次数比较,差异无统计学意义(P>0.05)。术后随访1年发现,所有患者均未出现癌细胞经手术切口种植转移的情况。结论在后腹腔镜肾根治性切除术中运用一次性切口保护套来辅助取标本,其手术时间短、操作简单,易上手,具有实用价值,值得临床推广应用。
