摘 要:目的:探索经尿道给予前列腺素E1(PGE1)治疗阳萎的可行性、安全性及剂量与效果关系。方法:采用单盲、安慰剂及自身逐级增量给药(150~1 200 μg)对照观察24例阳萎患者的剂量与效果(阴茎勃起角度、周径、长度变化及持续时间)的关系。结果:600 μg以内剂量与反应呈直线正相关,随剂量增大阴茎勃起质量增加,80%以上患者可达最佳效果;600 μg以上仅有20%以下的患者有进一步反应,且副作用增多。结论:PGE1治疗阳萎疗效确实,安全可靠,单独使用剂量应控制在600 μg以下。 关键词:阳萎 前列腺素E1 尿道内投药

Abstract:Purpose: To investigate the feasibility, safety and relationship of the dose-effectiveness of prostaglandin E1 (PGE1) with medicated urethral system for erection (MUSE). Methods: A single blind, placebo-controlled study of increasing dosages (150~1 200 μg) was done. 24 men with impotence were monitored in real time for 2 hours after MUSE, and penile erect angle (PEA), tumescence and duration of erection were measured. Results: The initial response to escalating doses of PGE1 from 150 μg to 600 μg demonstrated a steep dose-dependent increase, at greater than 600 μg indicating a nonliner response. More than 80% of the patients attained the maximal response at doses of 600 μg or less and less than 20% benefited from a further increase. Conclusions: The effects of PGE1 with MUSE appear to limit to 600 μg or less, since larger amounts offer little additional benefit. Key words:Impotence Prostaglandin E1 Intraurethral administration▲
经尿道给予前列腺素E1(PGE1)治疗阳萎是近年国内外学者正在探索的一条新的有效途径〔1,2〕。其疗效、安全性及用药量各家报告不一,亦未见严格的实验对照报告。本研究采用单盲、自身逐级增量给药及安慰剂对照的方法,研究经尿道给予PGE1剂量与反应的关系,观察其疗效、安全性及最适剂量。
1 资料与方法
1.1 临床资料 选择1995年3月~1997年12月本院男性科门诊患者24例,年龄32~62岁(平均45.8±9.0岁)。有阳萎病史10个月~8年(平均16±5个月)。17例(70.8%)患者曾在家经尿道用PGE1治疗4个月~2年。经详细询问病史,检查心电图、X线胸透、血常规、尿常规、血糖,测定内分泌激素(黄体生成激素、卵泡刺激素、睾酮、泌乳激素),作阴茎夜间勃起试验(NPT)(邮票法或断[1] [2] 下一页 上一个医学论文: 创伤性肝破裂91例 下一个医学论文: ESWL前后肾内血管阻力指数和尿中GAL与NAG检测的意义
