镍钛支架治疗前列腺增生4年随访报告

Nickel-titanium shape-memory alloy stent for the management of benign prostatic hyperplasia: 4 years follow up

目的:总结镍钛记忆合金网状支架治疗前列腺增生4年的疗效和不良反应。方法:对置入支架≥4年的112例患者进行随访,随访内容包括尿常规、国际前列腺症状评分(IPSS)、最大尿流率(Qmax)、剩余尿量(RU)和不适反应等。结果:置管后4年,IPSS、Qmax、RU分别为14.1±3.2分、14.8±5.4 ml/s、46.0±26.0 ml,与出院时相比无明显变化(P>0.05)。尿路感染和逆向射精是置管后的常见并发症。结论:镍钛合金网状支架治疗前列腺增生长期疗效稳定,严重并发症少,可成为治疗高龄、高危前列腺增生患者的首选方法。

Purpose:To evaluate the 4 years result using nickel titanium shape-memory alloy stent for patients with benign prostatic hyperplasia. Methods; 112 patients of BPH received Nickel-titanium shape-memory alloy stent were followed up and determined for symptom score (IPSS), peak urine flow rate(Qmax), residual urine volume (RU) and complications. Results: IPSS, Qmax and RU was(14. 1±3. 2) ,(14. 8 ± 5. 4)ml/s,(46. 0±26. 0) ml respectively 4 years later after the operations. Urinary infection and retrograde ejaculation were common complications. Conclusions: The results indicated that nickel-titanium shape-memory alloy stent was a safe, effective treatment for benign prostatic hyperplasia.
