  • Urine Cytology Silver Stain Combined with Ultrasonography in the Detection of Recurrence of Bladder Cancer

    Objective To evaluate the urine cytology silver staining combined with ultrasonography(USG)in the detection of bladder transitional cell carcinoma (TCC) recurrence after transurethral resection of bladder tumor(TURBT)in terms of sensitivity and specificity. Methods Cystoscopy was used as “gold standard”. Urine cytology combined with USG or cystoscopy was measured separately and blindly. AgNORs protein stained by silver were used in cytology with Kappa of inter-observers 0.81. For the USG, the patients were scanned with trans-rectal probe with Kappa of inter-observers 0.76. The results of urine cytology combined with USG (Positive when urine cytology and/or USG positive. Negative when both urine cytology and USG negative) were compared with “gold standard”. Results The 148 consecutive superficial TCC patients with TURBT one year previously were included in this study. Fifty seven recurrenced cases were detected. Recurrence rate was 38.51%. The sensitivity and specificity of urine cytology silver stain were 89.47% (95% CI 0.82 to 0.98) and 87.91% (95% CI 0.81 to 0.95). Area under ROC curve was 82.22%. The sensitivity and specificity of USG were 57.90% (95% CI 0.45 to 0.71 ) and 90. 11% ( 95% CI 0.84 to 0.96). Area under ROC curve was 73.13% . The sensitivity was improved to 94. 74% (95% CI 0.89 to 1.00) when cytology combined with USG. But specificity decreased to 84. 62% (95% CI 0.77 to 0.92 ). Area under ROC curve was improved to 98.28%. Conclusions Urine cytology silver stain combined with USG improves the high sensitivity for follow-up TCC patients after TURBT. The non-invasive protocol is suggested.

  • 窄波成像在膀胱癌早期诊断中的应用进展

    膀胱癌是泌尿系统最常见的恶性肿瘤、具有多发、易复发、复发后恶性程度提高等特点。虽然膀胱镜检查仍然是早期诊断膀胱癌的主要手段,但是目前常用的普通膀胱镜不易发现膀胱黏膜的细微病变,可能导致漏诊或手术治疗不彻底。窄波成像(NBI)是21世纪初新研发的全新诊断技术,其能够显著增强膀胱镜检查的对比度和清晰度,能够更加清楚地显示黏膜表层的毛细血管和腺管开口,不仅可以提高膀胱癌的早期诊断水平,还可以有效地为经尿道膀胱肿瘤电切术手术提供指导。尽管对NBI应用的远期效果以及能否减少膀胱癌患者术后膀胱灌注和膀胱镜检查的次数还有待进一步研究和观察,但是NBI技术所具有的独特优势为膀胱癌的早期诊断和治疗提供了新的契机。

  • 尿道热诊疗的经验分享与预防措施

    目的总结近年来膀胱镜室尿道相关操作后发生尿道热的患者的相关资料,探讨其发生的危险因素及预防措施。 方法对2015年1月-12月33例发生尿道热的患者的临床资料进行回顾性分析。 结果发生尿道热的患者中,72.7%的患者尿细菌培养呈阳性。而所有患者在操作前均未接受血常规、生物化学、尿常规检查,也未接受抗生素类相关药物。 结论防治尿道热的关键点在于预防,在进行扩尿道、膀胱镜检查等操作前应该进行相关的临床检查及处理,以避免尿道热发生。
