摘　　要：１９９３年８月～１９９４年８月利用镍钛形状记忆合金网状支架和自行研制的置入器治疗高危前列腺增生症６７例。其中６１例一次治疗成功，５６例（９１．８／）术后立即自行排尿，５例术后１～１２周内恢复自主排尿，总有效率９１．０４％（６１／６７）。２４例随访３个月以上，前列腺症状积分（Ｉ－ＰＳＳ）从术前２８．７９±３．７９减少到８．９２±３．５０（Ｐ＜０．００１），最大尿流率从术前１．８７±２．８１增加到１０．１７±１．２５ｍ１／ｓ（Ｐ＜０．００１），有显著性差异。本研究表明镍钛形状记忆合金网状支架治疗前列腺增生症安全、有效，近期疗效满意，中远期疗效正在观察研究中。From l993 to l994,67 high risk patients with benign prostatic hyperplasia have been treated with Nickel-Titanium shape-memory alloy net-like stent. 61(91. 04%)have been treated successfully at the first session,and 56(91.8%)could urinate immediately after treated. 5 patients had a normal urination in l-12weeks postoperatively,the total efficacy rate being 91. 04%(61/64 ). 24 have been followed up for 3 months or more,with the prostate symptom score(IPSS)decreased significantly from 28.7±9 preoperatively to 8. 92±3. 50 postoperatively(P<0.001).The peak urinary flow rate increased significantly from 1. 87±2. 81 preoperatively to 10. 17±2. 25 postoperatively ( P<0.001).The present study showed that Nickel-Titanium shape-memory alloy net-like stent for patients with benign prostatic hyperplasia was safe,efficient and promising,The long term efficacy of the stent has been under study.
