勃起功能障碍(ED)诊断和治疗效果的评估过程中,患者问卷是一种常用评估工具,其种类和数量也日渐增多。本文介绍了几种常见且有效的ED问卷,包括国际勃起功能问卷(IIEF)、男性性健康量表(SHIM)、IIEF勃起功能专项评分(IIEF-EF)、勃起硬度分级(EHGS)、自尊心及性关系问卷(SEAR)、勃起功能障碍治疗满意度量表(ED-ITS),以及勃起质量问卷(QEQ)、治疗满意度评分(TSS)、心理及人际关系评分(PAIRS)、性体验问卷(SEX-Q),并对其临床针对性做了讨论。     

轻到中度动脉性ED患者接受西地那非治疗后自发性勃起功能得到改善

为验证西地那非(50mg每晚服用持续一年)是否能改善轻到中度动脉性勃起功能障碍(ED)患者的自发性勃起功能(EF),Sommer F等人进行了一项前瞻性的开放性试验,研究入选112位男性ED患者,随机分为接受每晚西地那非50mg组或按需服用西地那非50mg或100mg组,随后进入1月和6月的非药物治疗期。非随机化、未服药ED患者也接受评估。用勃起功能国际指数(IIEF EF)的EF范围和阴茎海绵体动脉收缩速度峰值评估药物作用。结果显示在西地那非治疗后以及随后的非服药期,IIEF EF在48位夜间服药     

患者及伴侣对万艾可治疗勃起功能障碍的满意度调查

万艾可是治疗勃起功能障碍（ED）的有效、安全的药物，患者及伴侣的满意度均很高。Lewis R等人进行的一项研究再次证明了，患者及其伴侣对万艾可治疗ED的高满意度。他们对247位各种病因引发的ED患者进行研究。在12个星期中对接受西地那非（25、50和100mg）治疗的患者与接受安慰剂治疗的患者进行比较。其主要疗效指标使用国际勃起功能指标（IIEF）中的问题3（有能力获得勃起）和问题4（有能力维持勃起）及3个通用的功效问题进行评价。同时首次运用EDITS（勃起功能障碍治疗满意度）问卷对患者及伴侣治疗后的满意度进行评估。     

经尿道前列腺等离子双极电切术对阴茎勃起功能的影响(附100例报告)

目的:比较经尿道前列腺电切术(TURP)和经尿道前列腺等离子双极电切术(PKRP)治疗BPH后对患者阴茎勃起功能的影响,并探讨各自相关影响因素。方法:按1∶1比例随机分为TURP组和PKRP组,用勃起功能国际问卷(IIEF25)和Rigiscan硬度仪评测患者术前术后性功能变化;记录IIEF25评分、患者年龄、切除前列腺大小、手术时间、术中出血量、包膜损伤、逆行射精、电切综合征(TURS)等可能影响性功能的因素进行变量逻辑回归分析。结果:TURP组术后6个月有9例(18.0%)、PKRP组有5例(10.0%)发生阴茎勃起功能障碍(ED),术后ED与患者年龄、术前IIEF25评分、逆行射精及包膜损伤有显著相关性。结论:TURP、PKRP术对患者性功能均有不同程度的影响,而PKRP对性功能的影响较轻微;影响术后性功能比较显著的因素为患者年龄、包膜损伤、逆行射精和术前IIEF25评分。     

ED患者勃起功能和满意度之间的相关性

国际勃起功能评分（IIEF）已经成为药物及临床研究中评价性功能状态的金标准。勃起功能部分评分（EFD）的正常化，以及治疗结束后的IIEF评分在26分或更高作为治疗终点已常规应用于当前的药物临床研究中。在临床中，一些治疗后的ED患者虽然评分小于26分，但患者或／（和）其伴侣却对其性功能感到满意。为进一步了解在接受治疗后EFD评分〈26分的ED患者对治疗的满意度比率，Teloken P等人进行了一项研究[J Sex Med，2007，4（2）：472—476]。研究入选100例平均年龄58岁的男科门诊患者并已经接受了至少4个疗程的西地那非治疗的ED患者。     

西地那非治疗ED有效且显著提高性满意度

为评价常规使用西地那非的疗效,以及对患者性生活满意度及其伴侣满意度的影响。Gil A等进行了一项开放、多中心、前瞻性研究。入选的2816位患者都服用西地那非治疗至少10周。采用国际勃起功能评分(IIEF)评价疗效,生活满意度采用“生活满意检测表(LISAT8)”评价,EDITS则选择性用于评价伴侣对ED治疗的满意度。结果显示,西地那非对86．6％的患者有效。所有IIEF项目评分随西地那非的使用均明显提高,特别是在勃起功能方面,所有患者的平均分提高了13．2％(P＜0．001)。在生活满意度中提高最明显的是性生活和与伴侣的关系方面。回答问卷的患者伴侣均对疗效和药物的快速起效非常满意,并希望继续用药。不良反应与药品上市前的临床研究相似。     

影响ED性治疗临床推广应用的相关因素分析

目的:探讨勃起功能障碍(ED)性治疗在临床推广应用的影响因素。方法:在男科门诊向ED患者及伴侣推荐性治疗方法,免费为他们提供性治疗。在咨询与治疗过程中通过观察和访谈分析影响患者及伴侣参加性治疗的相关因素。结果:有许多ED患者和伴侣没能或拒绝参加性治疗,仅征得自愿参加性治疗的ED患者及伴侣共11对。且在性治疗过程中,有5对先后中途退出,1对由治疗师中止治疗,5对完成治疗。中途退出的原因:2对怀疑有器质性病变转而寻求药物治疗;1对同居伴侣因女方提出分手而退出;1对外地伴侣因路途遥远未能继续治疗;1对因夫妻双方工作压力大,无时间和精力继续参加治疗。1对治疗师中止治疗是由于治疗期间妻子婚外性行为导致夫妻感情破裂,治疗师认为已不适合继续进行性治疗。结论:在我国性治疗未能在临床推广应用的原因除从业人员少、性治疗本身存在一些不足外,还受患者及伴侣主、客观因素的影响,如工作压力及时间、居住地区、受教育程度、患者与伴侣的一般关系、对性治疗的态度等。     

A comparison of the International Index of Erectile Function and erectile dysfunction studies

OBJECTIVE: To evaluate the ability of the five-item version of the International Index of Erectile Function (IIEF-5) to diagnose the vascular aetiology and severity of erectile dysfunction (ED), and to compare it with pharmacological testing and duplex Doppler ultrasonography, as such questionnaires are widely used by the pharmaceutical industry to categorize the severity of ED and to assess the efficacy of drug therapy. PATIENTS AND METHODS: In all, 80 patients (mean age 45.2 years, sd 14.0; mean duration of ED 3.5 years) were reviewed by an examiner unaware of their IIEF scores during testing. Penile blood flow was assessed in each patient after an intracavernosal injection with prostaglandin-E1 (10 micro g), with self-stimulation in privacy. The peak systolic velocity, end diastolic velocity and resistive index were measured for the vascular diagnosis. Visual ratings of erectile responses were also used for analysis. RESULTS: Of the 80 patients, 30 had a normal vascular response, 38 arterial insufficiency and 12 were diagnosed with venous leakage. There was no significant difference in the IIEF scores among patients with a normal vascular response, arterial insufficiency or venous leakage. Analysis of visual ratings of erections showed no difference in IIEF scores among the different groups of patients. CONCLUSION: The IIEF was designed and developed specifically for assessing and evaluating sexual function in clinical trials. However, as shown here, the IIEF cannot and should not be used as a tool to diagnose or compare specific vascular causes of ED.     

Quality of life in patients with spinal cord injury receiving Viagra (sildenafil citrate) for the treatment of erectile dysfunction

STUDY DESIGN: A multicenter, randomized, double-blind, placebo-controlled, flexible-dose, two-way crossover study conducted June 1996 through January 1997. OBJECTIVES: To evaluate the effect of sildenafil citrate (VIAGRA(R)) on the quality of life (QoL) of men with erectile dysfunction (ED) caused by spinal cord injury (SCI). SETTING: Study centers in Australia, Belgium, France, Germany, Norway, Sweden and the United Kingdom. METHODS: Questions 13 and 14 of the 15-item International Index of Erectile Function (IIEF) addressed QoL issues directly related to ED in 178 men with SCI. A 5-item questionnaire addressing concerns that men had about their erection problems was also used to evaluate the impact of ED on QoL. Several commonly used psychometric instruments, including the Medical Outcomes Survey (MOS) Short Form-12, Psychological General Well-Being Index, and MOS Family Survey, assessed general QoL issues. RESULTS: Significant improvements were seen for overall satisfaction with sex life (IIEF Q13), sexual relationship with partner (IIEF Q14), and concerns about erectile problems (P<0.0001). Improvements were reported in scores for the generic QoL parameters of mental health, well-being, depression, and anxiety (P<0.05 sildenafil versus placebo). CONCLUSION: Treatment with sildenafil can significantly improve key QoL parameters in men with ED caused by SCI. Sponsorship: This study was funded by Pfizer Inc. Spinal Cord (2000) 38, 363 - 370.     

Erectile dysfunction, discrepancy between high prevalence and low utilization of treatment options: results from the 'Cottbus Survey' with 10 000 men

OBJECTIVE: To investigate the age-stratified prevalence of erectile dysfunction (ED) and its comorbidities, and to assess the population's knowledge, utilization, and general attitude towards the treatment for ED. SUBJECTS AND METHODS: In all, 10 000 men received a 35-item questionnaire including the International Index of Erectile Function (IIEF) and sociodemographic questions regarding life style, comorbidities, quality of sexual life and knowledge or experience of ED therapy. In all, 3124 responses were included (31.2%), 2499 men lived in well established partnerships and were assessed as the basic study group. RESULTS: In the entire population the prevalence rate of ED was 40.1%. However, although known, medical treatment for ED is used only by a minority of affected men. The prevalence of ED was independently associated with age, peripheral arterial occlusive disease, hypertension, ischaemic heart disease, diabetes mellitus, and liver diseases. Correlations between sexual quality of life (QoL) and ED were statistically significant (P < 0.01) and moderate to strong (absolute values: Spearman's rho 0.35-0.76). Although 96% of the study population knew at least one phosphodiesterase type 5 (PDE5) inhibitor by name, only 53% considered taking the medication and only 9% of the men with ED had had experience with available PDE5 inhibitors. CONCLUSIONS: The sexual QoL was significantly reduced by ED. Despite high levels of awareness and general acceptance of oral medication for ED, experience with PDE5 inhibitors was low. Further investigation is required to evaluate the general impact of ED on sexual QoL and the need or wish for treatment.     

Erectile dysfunction after open versus angioplasty aortoiliac procedures: a questionnaire survey

Erectile dysfunction (ED) is a common complication after aortoiliac surgery. The aims of this study were to determine the incidence of ED in patients with aortoiliac occlusive disease or aneurysm and evaluate the effect of revascularization by means of open surgery or iliac angioplasty/stenting upon erectile function by using the new International Index of Erectile Function (IIEF) questionnaire. All male patients who had previously undergone open aortoiliac reconstruction or iliac angioplasty/stenting and who were alive at the time of this study were first contacted by telephone. Those who agreed to take part in the study were sent anonymous IIEF questionnaires. Patients were asked to recall their sexual function before and 3 months after the procedure. ED was defined as IIEF score of <11. After telephone interview, a total of 116 patients agreed to take part in the study. The response rate was 61%. Two patients, one in each group, had ED preoperatively. The preoperative IIEF scores were no different in surgery and angioplasty/stenting groups (p=0.3). Overall, 46/63 patients reported worsening erectile function postoperatively. In the surgery group (n=37), 32 patients reported deterioration of their sexual function, 3 no change, and 2 improvement, while in the angioplasty/stenting group (n=26), 14 patients had deterioration, 11 no change, and 1 improvement. In both groups, the IIEF score decreased significantly postintervention; however, the deterioration was much more pronounced after open surgery (p<0.001). Of the 61 patients with "normal" erectile function (IIEF > or =11), 10 patients (28%) developed ED following surgery, but none after angioplasty/stenting (p=0.003). As judged by the IIEF, a significant proportion of patients undergoing open and endovascular procedures experience worsening sexual function.     

The utility of sildenafil citrate for infertile men with sexual dysfunction: a pilot study

OBJECTIVE: To investigate the use the sildenafil citrate, recognized as a first-line therapy for men with erectile dysfunction (ED), and which is safe and effective in men with various causes and severity of ED, including psychogenic ED, in a population of infertile men with sexual dysfunction. PATIENTS AND METHODS: Infertility is a major source of life stress and might be associated with sexual dysfunction through the erosion of self-esteem and self-confidence, and in stimulating discord in a relationship. Men presenting for evaluation of fertility who on questioning by the physician reported the recent onset of sexual dysfunction, had a history taken, a physical examination, hormonal profile, and completed the International Index of Erectile Function (IIEF), a validated inventory for assessing sexual dysfunction. Thirty men with a score of <26 on the erectile function domain of the IIEF, or who complained of new onset rapid or delayed ejaculation, were treated with sildenafil with no randomization or placebo control. The evaluation was repeated and the IIEF completed again > or =3 months after starting treatment. RESULTS: For men complaining of ED, subjective erectile rigidity, duration of erection, and the percentage of successful penetration attempts significantly improved with sildenafil. The mean (sd) IIEF domain scores for erection and satisfaction, at 18 (4) vs 27 (3), and 12 (2) vs 16 (3) (both P = 0.01), and orgasm, at 4 (1) vs 6 (3) (P = 0.001), respectively, significantly improved after treatment. In patients with ejaculatory dysfunction, the function improved in 64% after sildenafil therapy. CONCLUSIONS: We identified the nature of sexual dysfunction associated with male-factor infertility, and showed the efficacy of sildenafil therapy in men with this condition.     

High prevalence of erectile dysfunction after renal transplantation

BACKGROUND AND METHODS: A cross-sectional study of multifaceted male sexual function in 323 consecutive kidney transplant recipients was conducted by mail by means of the validated International Index of Erectile Function (IIEF). All five IIEF domains (IIEF-5), i.e., erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction, were scored for each responder. IIEF-5 scoring that conformed to the National Institutes of Health definition of erectile dysfunction (ED) was computed for all patients sexually active within the past 4 weeks. RESULTS: Two hundred and seventy-one patients replied. Compared to the controls used for IIEF psychometric validation, kidney transplant recipients gave lower erectile function (P<0.01) and intercourse satisfaction (P<0.05) scores, despite their being younger. ED, according to the IIEF-5 method, was demonstrated in 55.7% of the sexually active patients (n=212). Age, time on dialysis, and iterative transplants were significantly and negatively related to erectile dysfunction. CONCLUSION: IIEF proved to be a valuable means of unveiling highly prevalent erectile dysfunction in male kidney transplant recipients. The negative impact of the time on dialysis was emphasized in the results.     

女性伴侣在勃起功能障碍的诊治中的重要地位

女性伴侣在勃起功能障碍(erectile dysfunction,ED)中的地位日益受到重视。女性伴侣的性体验受到ED的严重不良影响,而她们对ED这个问题所采取的态度会直接影响男性患者寻求和坚持治疗的行为。因此在ED治疗的临床实践中,应同时考虑女性伴侣的作用。研究表明,伐地那非不仅可有效提高男性患者的勃起功能,还能显著改善女性伴侣的性生活质量,是ED伴侣双方的理想解决方案。     

Erectile dysfunction in a primary care setting: results of an observational, no-control-group, prospective study with sildenafil under routine conditions of use

In order to assess the effectiveness of sildenafil under routine conditions of use in primary care settings and to evaluate its impact on patient's life satisfaction and partner's satisfaction with treatment for erectile dysfunction (ED), an open, multicentre, observational, prospective study was designed in which 2816 patients were treated with sildenafil for at least 10 weeks. Effectiveness was assessed using the International Index of Erectile Dysfunction (IIEF), life satisfaction was measured with 'Life-satisfaction Check List' (LISAT 8), and EDITS was optionally used to assess the partner's satisfaction with ED therapy. Sildenafil was effective in 86.6% of patients. All dimensions of IIEF significantly increased with sildenafil, particularly erectile domain which overall sample mean score improved was 13.2 points (P < 0.001). The greatest increases in satisfaction with all aspects of life were seen in sex life and relationship with partner dimensions. The patients' partners, answered by a minority of partners, were highly satisfied with the treatment and its rapid action, therefore they were in favour of continuing with same. The adverse events occurring were similar to those seen in clinical research on sildenafil in the premarketing phase. No control group was included in this study.
