记忆合金支架治疗前列腺部尿道梗阻的远期疗效

目的 观察镍钛记忆合金网状支架治疗前列腺部尿道梗阻的远期疗效。方法 1993年11月—1996年8月应用网状镍钛记忆合金尿道支架治疗前列腺部尿道梗阻患者15例，其中前列腺增生14例，前列腺癌1例。分别于术后3个月及6年随访。结果 术后6年，症状明显改善，国际前列腺症状评分(IPSS)比术前减少16．6，残余尿(RUV)从平均151．2mL，减少至29．1mL，平均尿流率(MFR)从平均3．0mL／s增加到11．1mL／s。结论 镍钛记忆合金网状支架对治疗良性前列腺增生症(BPH)引起的前列腺部尿道梗阻是一种有效的措施，特别适用于不能耐受手术或预期寿命不长的尿潴留患者。

Management of Prostatic Urethral Obstruction:Long-term Experience with the Memotherm Stent

Purpose To determine the long-term efficacy of the Memotherm stent implan-ted in high risk patients with prostatic urethral obstruction. Methods From November 1993 to August 1996 we implanted the Memotherm stent into 15 high risk patients including 14 benign prostatic hyperplasia and 1 prostatic carcinoma. 16 assess the long-term effects we performed followups 3 to 72 months after implantation. As a measure of the efficacy of the sten we documented urinary flow and residual urine. To assess voiding symptoms and quality of life we used the International Prostate Symptom Score. Results Implantation of the Memotherm stent led to a decrease of residual urine from a mean of 151.2 to 29.1 mL, and to an increase of urinary flow from 3.0 to 11.1 mL per second. Patients had fewer voiding problems and noticed an increase in quality of life. Conclusions Treatment with the Memotherm stent offers a good alternative therapy for patients with prostatic urethral obstruction who cannot undergo surgery due to grave concomitant diseases.
