镍钛记忆合金网状支架在BPH患者的应用及远期疗效观察

目的观察镍钛记忆合金网状支架治疗良性前列腺增生症(BPH)的疗效及安全性。方法38例患者使用镍钛记忆合金网状支架治疗，除了5例患者失访，其余33例患者都得到观察或随访。结果除了2例患者因膀胱逼尿肌功能丧失而治疗失败，其他患者都可自行排尿，2例患者因支架移位而取出，3例患者在2年后恢复留置导尿，15例患者在31～48个月后得到随访，其IPSS评分为21.2±4.3分。结论镍钛记忆合金网状支架对治疗BPH是一种有效的措施，特别适用于不能耐受手术或预期寿命不长的尿潴留患者。

Use of the MemothermTMstent in benign prostatic hyperplasia:long-term results

Purpose:To determine the long-term safety and efficacy of the MemothermTM endoprosthesis as a therapeutic alternative in the management of men with BPH.Method:MemothermTM urethral stent was applied to thirty-eight men (mean age 77 years. Range 62-87 ) with symptoms and urodynamics suggestive of BPH.Results:Follow-up was lost in five patients. All but two patients with follow-up were eventually able to have spontaneous urination. Stents were removed from two patients because of dislocation. Prostatectomy was required in three patients at 15, 30 and 32 months respectively. Three patients resorted to indwelling catheterization after two years due to recurrence of symptoms. Information on 15 patients between 31 and 48 months follow-up was obtained. IPSS score was21.2±4.3.Conclusion:The long-term results from our trial unveiled that the Titanium-alloy memorial stents was an effective therapeutic alternative for patients having urinary retention with short life expectancy or operative contraindication.
