  • Clinical Application of Local Obturator Nerve Block Used in Transurethral Resection of Bladder Tumor

    目的:观察在经尿道膀胱肿瘤电切术中采用闭孔神经阻滞减少闭孔反射的情况及远期疗效。方法:选取2005年1月~2006年5月期间我科收治的60例确诊膀胱肿瘤患者,严格按照手术适应症随机分为两组:对照组30例单纯硬膜外麻下行经尿道肿瘤电切术,治疗组30例在硬膜外麻醉基础上进行闭孔神经阻滞,观察两组闭孔反射发生率并进行术后随访,观察肿瘤的复发情况。结果:对照组闭孔反射发生率明显高于治疗组(Plt;0.05),经过随访治疗组30例患者3例出现了膀胱肿瘤复发,复发率为10.0%,对照组复发率为13.3%(4/30),两组复发率无明显差异(Pgt;0.05)。结论:在经尿道膀胱肿瘤电切术中采取闭孔神经阻滞能明显减少闭孔反射的发生,明显提高手术的效果,但是改善膀胱肿瘤近期和远期疗效还有待进一步探讨。

  • Comparison of inguinal approach versus classical pubic approach for obturator nerve block in transurethral resection of bladder tumors: a meta-analysis

    ObjectiveTo evaluate the clinical efficacy and safety of the inguinal approach versus classical pubic approach for obturator nerve block (ONB) in transurethral resection of bladder tumors (TUR-BT).MethodsDatabases including PubMed, The Cochrane Library, EMbase, Web of Science, WanFang Data, CNKI and VIP databases were electronically searched to identify randomized controlled trials using ONB in TUR-BT from inception to May 2020. Two reviewers independently screened literature, extracted data, and assessed risk bias of included studies. Meta-analysis was performed by using Stata 14.2 software.ResultsA total of 7 studies involving 474 patients were included. The meta-analysis results showed that there was no significant difference between inguinal approach and pubic approach in terms of the ONB success rate (RR=1.06, 95%CI 0.96 to 1.17, P=0.23), while the one-time success rate of puncture of inguinal approach was higher than that of pubic approach (RR=1.47, 95%CI 1.01 to 2.15, P=0.04). Compared with the pubic approach, the overall complications of inguinal approach were lower (RR=0.24, 95%CI 0.08 to 0.71, P=0.01). However, no significant difference was found between the two groups in terms of subcutaneous hematoma (RR=0.46, 95%CI 0.08 to 2.66, P=0.38).ConclusionsThe current evidence indicates that the success rate of one puncture of inguinal approach is higher than that of pubic approach, and the overall complications of the inguinal approach are much lower than that of the pubic approach. However, the above conclusions are still required to be verified through more high-quality studies due to the limited quantity and quality of included studies.
