高龄前列腺增生的内支架治疗

The metallic stent therapy for senile patients with benign prostatic hyperplasia

目的探讨前列腺内支架治疗高龄前列腺增生的临床疗效。方法回顾性分析32例前列腺增生引起排尿困难的老年患者进行前列腺内支架植入术。结果32例患者前列腺内支架均一次植入成功,术后立即自行排尿,无严重手术相关并发症。32例患者术后随访,国际前列腺症状评分(IPSS)由术前(25.50±5.51)ml/s降至术后(6.51±3.87)ml/s(P<0.01),最大尿流率从术前(1.55±3.64)ml/s增至术后(14.21±3.15)ml/s(P<0.01)。结论前列腺支架治疗前列腺增生引起的排尿困难,其疗效迅速、可靠、创伤小,尤其对治疗高龄、高危且不适宜手术的前列腺增生患者为首选方法。

Objective To evaluate the therapeutic effects of endo-stenting for senilel patients with benign prostatic hyperplasia. Methods 32 cases of elder dysuriac with hyperplasia of prostate treated by metallic endo-stenting were retrospectively analized. Results All stents were once placed successfully in 32 patients with free urination immediately afterward and without severe complication. After the successful placement of stent, the International Prostate Symptom Score （IPSS）decreased from a mean of（25.50 ± 5.51 ） ml/s to（6.51 ± 3.87） ml/s（P 〈 0.01）, and the mean maximum flow rates increased from（1.55 ±3.64） ml/s to （14.21 ± 3.15） ml/s（P 〈 0.01 ）. Conclusion The metallic stent implantation is a quick, reliable and minimal invasive therapy for the dysuriac with hyperplasia of prostate, and should be the first method of choice for the senile patients with high risk on surgical operation. （J Intervent Radiol, 2007, 16： 615-617）
