This retrospective report describes treatment of 21 patients who underwent prostatic artery embolization using 70- to 150-μm radiopaque microspheres for lower urinary tract symptoms secondary to benign prostatic hyperplasia. Seventeen patients (81%) received successful bilateral prostatic artery embolization. At a mean follow-up of 42 days (range, 25–59 days), patients showed improvement in International Prostate Symptom Score (n = 11; mean = 10.6; P = .001), quality of life score (n = 17; mean = 2.0; P = .02), and International Index of Erectile Function (n = 17; mean = 9.3; P = .01). The mean prostate volume reduction was 28 mL (16.2%; P = .003). Nontarget embolization occurred twice, resulting in 1 minor adverse event of hematospermia.

这份回顾性报告描述了使用70至150μm的不透射线微球对21例行前列腺动脉栓塞术的患者的治疗，以治疗继发于良性前列腺增生的下尿路症状。17名患者（81％）成功完成了双侧前列腺动脉栓塞术。平均随访42天（25-59天），患者表现出国际前列腺症状评分（n = 11；平均值= 10.6；P  = 0.001），生活质量评分（n = 17； n = 17； n = 10； n = 10； n = 10）。平均值= 2.0；P  = .02）和国际勃起功能指数（n = 17；平均值= 9.3；P  = 0.01）。平均前列腺体积减少为28 mL（16.2％; P = .003）。非目标栓塞发生两次，导致1个轻微的血精症不良事件。
