Comparison between Antegrade versus Retrograde Ureteral Stent Placement for Malignant Ureteral Obstruction

PurposeTo compare the technical success of antegrade uteral stent (AUS) and retrograde ureteral stent (RUS) placements in patients with malignant ureteral obstruction (MUO) and to determine the predictors of technical failure of RUS.Materials and MethodsThis study retrospectively included 61 AUS placements (44 patients) performed under fluoroscopic guidance and 76 RUS placements (55 patients) performed under cystoscopic guidance in patients with MUO from January 2019 to December 2020. Technical success rates of the 2 techniques were compared using inverse probability of treatment weighting (IPTW) analysis. Logistic regression was used to identify predictive factors for technical failures.ResultsTechnical success was achieved in 98.4% of the AUS group and 47.4% of the RUS group. After stabilized IPTW, the technical success rate was higher in the AUS group than in the RUS group (adjusted risk difference, 49.4%; 95% confidence interval [CI], 35.4%–63.1%). The independent predictors for technical failure of the RUS procedure were age of ≥65 years (odds ratio [OR], 5.56; 95% CI, 1.73–21.27), ureteral orifice invasion (OR, 4.21; 95% CI, 1.46–13.46), and extrinsic cancer (OR, 15.58; 95% CI, 2.92–111.81).ConclusionsThe technical success rate of AUS placement was higher than that of RUS placement in patients with MUO. RUS failure was associated with age of ≥65 years, cancer with ureteral orifice invasion, and extrinsic ureteral obstruction.     

Fabrication of a metal-ceramic crown to fit an existing partial removable dental prosthesis using ceramic pressed to metal technique: a clinical report

Fabricating a crown to retrofit an existing abutment tooth for a partial removable dental prosthesis (PRDP) is one of the most time-consuming and labor-intensive clinical procedures. In particular, when the patient is concerned with esthetic aspects of restoration, the task of fabricating becomes more daunting. Many techniques for the fabrication of all-metallic or metal-ceramic crowns have been discussed in the literature. This article was aimed to describe a simple fabrication method in which a retrofitting crown was fabricated for a precise fit using a ceramic-pressed-to-metal system.     

经皮冠状动脉支架植入术后个性化健康教育对提高患者自我管理能力的影响

目的：观察个性化健康教育模式应用于经皮冠状动脉支架植入术( PCI)后患者中对改善其自我管理能力的作用，总结其临床可行性。方法选择在我院2014年6月至2015年6月期间行PCI治疗后的患者60例，分别对其一般资料、疾病资料及健康知识进行调查，收集调查结果进行分类，给予个性化健康教育，观察护理前后患者自我管理能力评分的变化。结果所有患者在实施个性化健康教育后，对该疾病的健康知识认知水平及自我管理能力各维度得分对比干预前，均都有不同程度的改善，(P<0．05)，差异具有统计学意义。结论个性化健康教育模式应用在PCI术后患者中可以明显提高患者对疾病的认知程度，从而提高术后自我管理能力，有重要的临床使用价值。
