摘要 目的：了解三种镍钛合金支架治疗膀胱颈梗阻的疗效和有效时间。方法：1992年3月～1999年6月应用镍钛螺旋支架治疗前列腺梗阻35例(螺旋支架组)，应用国产镍钛网状支架治疗前列腺梗阻58例(国产网架组)，应用Angiomed网状支架治疗前列腺增生23例(Angiomed网架组)。结果：螺旋支架组随访21～60个月，显效8例(22.8%)，有效24例(68.6%)，平均有效时间10.8个月；国产网架组随访24～66个月，2年有效率85.7%，3年有效率76.8%，4年有效率62.8%；Angiomed网架组随访23～64个月，2年有效率100%，3年有效率91.6%，4年有效率88.8%，平均有效时间41.4个月。结论：螺旋支架仅作为临时支架目前临床已很少应用；国产网架有足够大直径和支撑力，易嵌入尿道而被粘膜覆盖成为永久性支架，而且价格为大多数患者所接受；Angiomed网架有较高组织相容性，刺激性小，易为上皮覆盖，其疗效优于国产网架。

Abstract Purpose: In order to know the effectiveness of three different urethral stents in the treatment of prostatic obstruction . Methods: 35 cases were treated with spiral stents (group on e) from Mar.1992 to Jun.1999,including benign prostatic hyperplasia (BPH) 34 cases, prostatic cancer 1 case, mean age 71.5years. From Oct.1993 to Jun.1999,58 cases were implanted with tubular meshes (group two), including BPH 54, advanced prostate cancer 4, mean age 76.9 years. During the same period as group tow, 23 cases with BPH were treated with Angiomed mesh (Urolume memotherm,group three), mean age was 75.1years, in which 17 received epidural anesthesia and percutanous cystostomy. Results: For group one, good results were achieved in eight cases (22.8%) and significant improvements occurred in 24 (68.5%) with a follow up of 21～60 months, mean effective time was 10.8 months. For group two, a dramatically effective rate was obtained in 54 (96%), with a follow up of 24～66 months (mean 42.6 months), two, three and four year effective rates were 85.7%, 78% and 63%. With a follow up of 23～64 months, we have got 100%, 91.6% and 88.8% of two, three and four year effective rat[1] [2] [3] 下一页
