目的回顾总结应用记忆合金网状支架治疗前列腺增生症 (BPH)合并膀胱出口梗阻的远期疗效。方法应用国产镍钛合金网状支架治疗 BPH患者 12 1例 ,术后 12、2 4、48个月分别随访 ,重新评定疗效。结果术后 12、2 4、48个月有效率分别为 91.5 %、80 .9%、64 .3 % ;国际前列腺症状评分由术前的 2 5 .4减少至 8.5 ,最大尿流率从术前 119.3 ml减少至 5 2 .8ml。结论前列腺尿道测量的准确性 ,支架安放的准确性影响手术的远期疗效。网状支架仍然适用于前列腺增生症的高危患者。
Objective To review the long-term efficacy of memory alloy mesh stent in the treatment of benign prostatic hyperplasia (BPH) with bladder outlet obstruction. Methods A total of 121 patients with BPH were treated with a domestic nickel-titanium alloy mesh stent. The patients were followed up for 12,2,48 months after operation to reevaluate the curative effect. Results The effective rates at 12,2,48 months after operation were 91.5%, 80.9% and 64.3% respectively. The International Prostate Symptom Score decreased from 2.55 to 8.5 before surgery. The maximal uroflow rate increased from The first 119.3 ml was reduced to 52.8 ml. Conclusion The accuracy of prostatic urethra measurement and the accuracy of stent placement influence the long-term efficacy of surgery. Reticular stent is still suitable for high-risk patients with benign prostatic hyperplasia.
