Abstract

Objective: To determine the effect on penile haemodynamics of vascularization using the Hauri method for the treatment of erectile dysfunction of vascular aetiology, as assessed by penile perfusion and functional scintigraphy.

Patients and methods: Penile perfusion and functional scintigraphy were performed before and after penile revascularization by the Hauri method in 13 patients. The established method of scintigraphy was carried out using 10 MBq/kg body weight of 99m technetium pertechnetate for in vivo labelling of erythrocytes, modified by including an estimate of mean virtual blood inflow rate.

Results: In 10 of the 13 patients there was a significant increase in the mean virtual blood inflow rate after surgery (P < 0.01, Wilcoxon test). In three patients, the inflow rate was lower after surgery than before; Doppler ultrasonography showed an occluded anastomosis in these patients.

Conclusions: Penile vascularization using the Hauri method provides an objectively demonstrable improvement in penile haemodynamics in man. It is thus a sufficiently therapeutic procedure for treating erectile dysfunction of vascular aetiology and its effect greatly exceeds any 'psychological influence'.

阴茎灌注和功能显像:显微手术血运重建术前后的初步临床结果。

目的:探讨Hauri法血管化治疗勃起功能障碍对阴茎血流动力学的影响，并通过阴茎血流灌注和功能显像评估其血管病因。患者与方法:对13例患者行Hauri法阴茎血运重建术前后进行阴茎灌注及功能显像检查。采用10 MBq/kg体重99m高技术酸锝对红细胞进行体内标记，并通过估计平均虚拟血流入率进行修改。结果:13例患者中有10例术后平均虚血流入率显著升高(P < 0.01, Wilcoxon检验)。3例患者术后血流流入率低于术前;多普勒超声显示吻合口闭塞。结论:使用Hauri方法的阴茎血管化提供了一个客观证明的改善男性阴茎血流动力学。因此，它是治疗血管病因性勃起功能障碍的一种充分的治疗方法，其效果大大超过任何“心理影响”。
