镍钛记忆合金网状支架治疗高危良性前列腺增生12例疗效分析

Effect Analysis of 12 Case of Nickel-titanium Shape-memory Alloy Mech Stent Treatment for High Risk Patients with Benign Prostatic Hyperplosis

目的 探讨镍钛记忆合金网状支架治疗高危良性前列腺增生患者的临床疗效.方法 镍钛记忆合金网状支架治疗高危患者前列腺增生12 例.结果 所有病例置管成功,例拔管后排尿通畅.术前国际前列腺症状评分（IPSS）21.2 ±3.8,最大尿流率（Qmax）（2.2 ±1.6）ml /s,剩余尿（RUV）140 ±26 ml,术后IPSS 6.2 ±3.3,Qmax（14.6 ±8.6）ml /s,RUV 52 ±24 ml,术前术后指标差异有统计学意义.结论 镍钛记忆合金网状支架疗效良好,为高危前列腺增生症的治疗提供了一种新的选择.

Objective To evaluate the clinical effect of nickel-titanium shape-memory alloy mesh stent for the management of high risk patients with benign prostatic hyperplasia. Methods patients with BPH were treated by the placement of balloon localizer nickel-titanium shape-memory alloy mesh stent .Results Ninteen out of 21 patients undergone the placement of alloy stent obtained free urination successfully in 90%. The preoperative and postoperative IPSS were 21.2±3.8 and6.2 a：3.3,Qmax were （2.2 ±l.6）ml /s and （14.6 ±8.6）ml /s ,RUV were 140 ±26 ml and 52 ±24 ml respectively. Conclusions The nickel-titanium shape-memory alloy mesh stenting is safe, effective and satisfactory treatment for high risk patients with benign prostatic hyperplasia.
