经尿道低温双极等离子技术治疗前列腺增生术后膀胱颈挛缩

Transurethral hypothermal bipolar plasma technique for bladder neck contracture following prostatectomy

目的探讨经尿道低温双极等离子技术治疗前列腺增生术后膀胱颈挛缩的疗效。方法前列腺增生术后膀胱颈挛缩患者共35例，采用等离子探针式电极和等离子袢状电切环两种设备经尿道分别置入后切除膀胱颈后唇瘢痕组织，扩大膀胱颈口。结果所有患者术后症状均得到改善，最大尿流率（18．1±3．3）ml／s和平均尿流率（8．4±1．3）ml／s，均高于术前，差异具统计学意义（P〈0．05）；随访9至30个月，除2例复发经再次手术治愈外，其余均一次治愈。结论经尿道低温双极等离子技术治疗前列腺增生术后膀胱颈挛缩，是一种安全、疗效确切的微创手术方法。

Objective To investigate the effect of transurethral bipolar plsamakinetic technique for the management of bladder neck contracture（BNC） following suprapubic or transurethral prostatectomy Methods A total of 35 patients underwent section of the bladder neck scar tissues to expand the bladder neck using isoionic probe electrodes and isoionic loop electrode rings. Results Symptoms were totally relieved, immediately after the procedure The maximum urine flow rate was （18.1±3.3）ml/s, and the average urine flow rate was （8.4±1.3）ml/s, much higher than that before surgery. In the period of follow-ups, recurrence was only found in two patients, and they were cured with the same procedure Conclusion This minimally invasive surgery is effective and safe for management of the bladder neck contracture following suprapubic or transurethral prostatectomy.
