目的评估镍钛记忆合金网状支架治疗前列腺增生(BPH)伴尿潴留远期疗效。方法对175例年龄61～103岁,平均(83.5±4.2)岁BPH患者应用镍钛记忆合金网状支架治疗,术后36、60个月进行随访。结果术后36、60个月的总有效率分别为75%、58%。结论镍钛记忆合金网状支架治疗前列腺增生伴尿潴留远期疗效不如近期疗效,但对高龄、高危BPH伴尿潴留的患者是一种有效的方法。
Objective To evaluate the long-term effect of nickel-titanium memory alloy mesh stent in the treatment of benign prostatic hyperplasia (BPH) with urinary retention. Methods One hundred and seventy 175 BPH patients aged 61- to 103-years (mean age 83.5 ± 4.2 years) were treated with nitinol mesh stent. The follow-up was performed 36 and 60 months after operation. Results The total effective rates 36 and 60 months after operation were 75% and 58% respectively. Conclusion The long-term curative effect of NiTi mesh stent in the treatment of benign prostatic hyperplasia with urinary retention is not as good as the recent curative effect, but it is an effective method for elderly and high-risk BPH patients with urinary retention.
