镍钛记忆合金支架治疗前列腺增生症216例

Nickel-titanium shape-memory alloy stent for the management of benign prostatic hyperplasia

目的 总结镍钛记忆合金网状支架治疗高龄、高危前列腺增生症的经验。方法 前列腺增生患者216例,年龄67-89(平均76.5)岁。置管前国际前列腺症状评分(IPSS)为(21.7±5.6)分、最大尿流(Qmax)(8.7±3.1)ml/s,剩余尿量(RU)(158±114)ml。在低位腰麻或硬膜外麻醉下置管,随访1年进行尿常规检查、IPSS、Qmax、RU测定、记录不适反应。结果 置管一次成功194例,2次成功18例,成功率为98％;平均置管时间:15～45min,平均住院时间:12d。多数患者术后有尿频、尿急、血尿等症状。置管后3年IPSS、Qmax、RU分别为:(13.7±4.1)、(14.8±4.5)ml/s和(38.0±21.0)ml。结论 镍钛合金网状支架可作为治疗高龄、高危前列腺增生症患者的首选方法。

Objective To present the experience in using nickel - titanium shape- memory alloy stenr for patients with benign prostatic hyperplasia(BPH). Methods 216 (BPH)patients were studied,with age of 67 to 89{mean 76. 5)ycars. International prostate Symptom Score (IPSS), peak urine flow rate (Qmax) and residual urine volume (RU) were (21.7?.6) ,(8.7 ?3. l)ml/s and (158. 0?114.0)ml before operation respectively. The operation was performed under spinal anesthesia or epidural aneathesia. Urinalysis, IPSS, Qmax and RU were followed up for 1 year. Results The operation success rate was 98% . Urinary frequency, urgency and hematuria were found in some patients after operation. IPSS, Qmax and RU were (13.7 ?. l) ,(14.8 ?.5)mL/s and (38.0?1.0)ml 3 year later respectively. Conclusion The nickel - titanium shape - memory alloy stent is safe, effective with less complication in the treatment of BPH.
