摘要

背景:经尿道膀胱肿瘤切除术在非肌性浸润性膀胱癌的诊断和治疗中存在一定的局限性。目的:探讨针电极在经尿道单膀胱肿瘤(SBT)切除中的应用,强调膀胱肿瘤整体切除的优势。方法:对中国人民解放军总医院泌尿外科2009年1 - 12月收治的79例SBT患者进行回顾性分析。其中男性64例(81.0%),女性15例(19.0%),平均年龄62.6岁。其中68例(86.1%)为原发肿瘤,11例(13.9%)为复发肿瘤,2例(2.5%)为上尿路上皮癌根治性切除术后的SBTs。所有患者均采用针电极经尿道膀胱肿瘤切除术。结果:所有手术均顺利完成。平均手术时间51.0 min,平均出血量7.9 mL,中位肿瘤大小2 cm。封闭神经阻滞22例(33.8%)。闭孔神经反射发生率为40.9%(9/22),无23.3% (10/43)(p = 0.139)。术后并发症包括1例(1.3%)膀胱填塞。肌侵犯报告准确率为89.9%。3例患者失访,2例(2.6%)6个月复发。中位随访时间为13个月。结论:针电极切除术治疗SBTs安全性高,并发症发生率低,肿瘤分期准确,治疗精准,术后复发率低。

Application of needle electrodes in en bloc resection of single bladder tumor.

Background: Transurethral resection of bladder tumor is associated with some limitations when used in the diagnosis and treatment of non-muscle invasive bladder cancer.

Objectives: This study explored the application of needle electrodes in the transurethral resection of single bladder tumor (SBT) and highlighted the advantages of en bloc resection of bladder tumors.

Methods: A retrospective analysis was conducted on 79 patients with SBT treated at the Department of Urology, People's Liberation Army General Hospital, from January to December 2023. Among the patients, 64 (81.0%) were male, and 15 (19.0%) were female, with a mean age of 62.6 years. Among the patients, 68 (86.1%) had primary tumors, 11 (13.9%) had recurrent tumors, and 2 (2.5%) had SBTs following upper urothelial carcinoma radical resection. All patients underwent transurethral resection of bladder tumors using needle electrodes.

Results: All procedures were successfully completed. The mean operation time lasted 51.0 min, and the mean blood loss was 7.9 mL. The median tumor size was 2 cm. The obturator nerve block was employed in 22 (33.8%) cases. The incidence of obturator nerve reflex was 40.9% (9/22) and 23.3% (10/43) without (p = 0.139). Post-operative complications included bladder tamponade in one patient (1.3%). The accuracy of muscle invasion reporting was 89.9%. Three patients were lost to follow-up, and two patients (2.6%) suffered from recurrence at 6 months. The median follow-up time was 13 months.

Conclusion: Needle electrode resection for SBTs was highly safe, had low complication rates, and offered accurate tumor staging, resulting in precise treatment and low postoperative recurrence.
