A simplified pharmacologic erection program for patients with spinal cord injury

Erectile dysfunction in common neurological conditions: A narrative review

Neurogenic erectile dysfunction (NED) can be defined as the inability to achieve or maintain an erection due to central or peripheral neurologic disease. Neurologic diseases can also affect the physical ability and psychological status of the patient. All these factors may lead to a primary or secondary NED. Medication history plays an important role since there are many drugs commonly used in neurologic patients that can lead to ED. The assessment of NED in these patients is generally evolving with the application of evoked potentials technology in the test of somatic and autonomic nerves, and functional magnetic resonance imaging. With the electrophysiological examinations, neurogenic causes can be determined. These tools allow to categorize neurologic lesion and assess the patient prognosis. The first-line treatment for NED is phosphodiesterase inhibitors. Second-line treatments include intracavernous and intraurethral vasoactive injections. Third-line treatments are penile prostheses. The efficacy and safety of each treatment modality depend on the specific neurologic condition. This review discusses the physiology, pathophysiology, diagnosis, and treatment of ED in multiple peripheral and central neurologic conditions, as well as for future research.

Performance and safety of treatment options for erectile dysfunction in patients with spinal cord injury: A review of the literature

BACKGROUND

For a large proportion of patients with spinal cord injury, sexuality and reproduction are important issues. However, sparse data exist regarding available treatment options for this patient population.

OBJECTIVES

We sought to review performance and safety rates of all currently available treatment options for erectile dysfunction in spinal cord injury men.

MATERIALS AND METHODS

A systematic literature review without time restrictions was performed using PubMed/EMBASE database for English-, Italian-, German-, and Spanish-language articles. Articles' selection was performed according to the PRISMA guidelines. Relevant papers on erectile dysfunction in spinal cord injury patients were included in the final analyses.

RESULTS AND DISCUSSION

Overall, 47 studies were eligible for inclusion in this review. Of these, most evidence dealt with phosphodiesterase 5-inhibitors and intracavernous drug injection. Both treatment options are associated with high levels of performance and with patients/partners' satisfaction; side effects are acceptable. Overall, penile prostheses and vacuum erection devices are in general less approved by spinal cord injury patients and are correlated with increased rates of complications in comparison with phosphodiesterase 5-inhibitors and intracavernous drug injection. Sacral neuromodulation, transcutaneous electrical nerve stimulation, and intraurethral suppositories have been poorly studied, but preliminary studies did not show convincing results.

CONCLUSION

The best treatment options for erectile dysfunction in spinal cord injury patients emerged to be phosphodiesterase 5-inhibitors and intracavernous drug injection. The choice of erectile dysfunction treatment should be based on several aspects, including residual erectile function, spinal cord injury location, and patients' comorbidities. Future studies assessing the applicability of less well-studied treatments, as well as evaluating innovative options, are needed in this specific population.

Sexual dysfunction in patients with spinal cord lesions

Many aspects of sexuality can be disrupted following a spinal cord lesion (SCL). It can alter an individual's self-esteem and body image, interfere with positioning and mobility, introduce unexpected problems with incontinence and spasticity, decrease pleasure, and delay orgasm. Sexual concerns in men can involve erectile function, essential for intercourse, ejaculation function, necessary for fertility, and the ability to reach orgasm. In women they can involve concerns with vaginal lubrication, genital congestion, and vaginal infections, which can all go unnoticed, and orgasm, which may be lost. All of these concerns must be addressed during rehabilitation as individuals with SCL continue to live an active sexual life, and consider sexuality among their top priority for quality of life. This chapter describes the impact of SCL on various phases of men's and women's sexual responses and on various aspects of sexuality. Treatments are described in terms of what is currently available and what is specific to the SCL population. New approaches in particular for women are described, along with tips from sexual counseling which consider an overall approach, taking into account the primary, secondary, and tertiary consequences of the SCL on the individual's sexuality. Throughout the chapter, attempts are made to integrate neurophysiologic knowledge, findings from the literature on SCL, and clinical experience in sexual rehabilitation.

Recommendations for discussing sexuality after spinal cord injury/dysfunction in children, adolescents, and adults

BACKGROUND/OBJECTIVE

To review the literature and provide a framework for sex education for the child, adolescent, or adult with a spinal cord injury (SCI) or disorder.

METHODS

Discussion and review of the literature.

RESULTS

There is a paucity of research available regarding the impact of SCIs and disorders on sexuality in children and adolescents; however, there is a significant body of literature on this topic in adults. Recommendations based on these findings are presented. Guidelines regarding sexuality in children and adolescents with general disabilities may be adapted for the education of children and adolescents with SCIs and disorders.

CONCLUSIONS

Parents, partners, and persons with SCIs and disorders should be provided with age-appropriate information about sexuality that includes specific information with respect to SCIs and disorders. Although there has been a significant increase in information that is available about the impact of sexuality in adults after SCI, more information is needed about the effects of SCIs and disorders on the healthy sexual development of children and adolescents.

Erectile dysfunction in spinal cord-injured men: different treatment options

To evaluate the efficacy, safety and patients' preference of different treatment modalities of ED in men with SCI. Sixty SCI men with ED were included in the study. They were divided into three groups. Group A received sildenafil, group B received intracorporal injection (ICI) and were then shifted to sildenafil and group C used vacuum constriction devices (VCD) and were then shifted to sildenafil. Erection was evaluated before and after each treatment. Ninety percent of patients reported improvement of erection after sildenafil and ICI treatment according to IIEF-EF and only 70% of patients reported improvement in erection with VCD. However, 14 patients reported that they preferred sildenafil due to the easier route of administration. In men with SCI, sildenafil is the most effective treatment and is widely accepted. ICI, VCD therapy in SCI patients should be used according to patient's preference and choice.

Male erectile dysfunction following spinal cord injury: a systematic review

STUDY DESIGN

Systematic review.

OBJECTIVE

To review sexuality in persons with spinal cord injuries (SCIs), and to report the effectiveness of erectile interventions.

METHODS

Reports from six databases (1966-2003), selected annual proceedings (1997-2002) and manufacturer's information were screened against eligibility criteria. Included reports were abstracted and data pooled from case-series reports regarding intracavernous injections and sildenafil.

RESULTS

From 2127 unique reports evaluated, 49 were included. Male sexual dysfunction was addressed in these reports of several interventions (behavioural therapy, topical agents, intraurethral alprosatadil, intracavernous injections, vacuum tumescence devices, penile implants, sacral stimulators and oral medication). Penile injections resulted in successful erectile function in 90% (95% CI: 83%, 97%) of men. Sildenafil resulted in 79% (95% CI: 68%, 90%) success; the difference in efficacy was not statistically significant. Five case-series reports involving 363 participants with penile implants demonstrated a high satisfaction rate, but a 10% complication rate.

CONCLUSIONS

A large body of evidence addressing sexuality in males focuses on erection. Penile injection, sildenafil and vacuum devices generally obviate the need for penile implants to address erectile dysfunction. Interventions may positively affect sexual activity in the short term. Long-term sexual adjustment and holistic approaches beyond erections remain to be studied. Rigorous study design and reporting, using common outcome measures, will facilitate higher quality research. This will positively impact patient care.

Neurogenic erectile dysfunction

Penile erection is a neurovascular event modulated by psyche and hormones. Erectile dysfunction (ED) has been classified as psychogenic, arteriogenic, neurogenic, endocrinologic, and cavernosal, based on the organs that are involved in penile erection. Among these types, neurogenic ED may be the most common, probably because a deficiency of neurotransmitters is the final common pathway in many diseases and conditions. This review discusses the physiology, pathophysiology, diagnosis, and treatment of erectile function and dysfunction, as well as strategies for future research.

Sexual function in spinal cord lesioned men

STUDY DESIGN

Review of literature.

OBJECTIVE

To review the physical aspects related to penile erection, ejaculatory dysfunction, semen characteristics, and techniques for enhancement of fertility in spinal cord lesioned (SCL) men.

SETTING

Worldwide: individuals with traumatic as well as non-traumatic SCL.

RESULTS

Recommendations for management of erectile dysfunction in SCL men: If it is possible to obtain a satisfactory erection but of insufficient duration, then try to use a venous constrictor band to find out if this is sufficient to maintain the erection. Otherwise we recommend Sildenafil. If Sildenafil is not satisfactory then use intracavernous injection with prostaglandin E(1) (some SCL men may prefer cutaneous or intraurethral application). We discourage the implantation of penile prosthesis for the sole purpose of erection. Recommendations for management of ejaculatory dysfunction in SCL men: Penile vibratory stimulation (PVS) to induce ejaculation is recommended as first treatment choice. If PVS fails, SCL men should be referred for electroejaculation (EEJ). Semen characteristics: Impaired semen profiles with low motility rates are seen in the majority of SCL men. Recently reported data gives evidence of a decline in spermatogenesis and motility of ejaculated spermatozoa shortly after (few weeks) an acute SCL. It is suggested that some factors in the seminal plasma and/or disordered storage of spermatozoa in the seminal vesicles are mainly responsible for the impaired semen profiles in men with chronic SCL. Fertility: Home insemination with semen obtained by PVS and introduced intravaginally in order to achieve successful pregnancies may be an option for some SCL men and their partners. The majority of SCL men will further enhance their fertility potential when using either PVS or EEJ combined with assisted reproduction techniques such as intrauterine insemination or in vitro fertilization with or without intracytoplasmic sperm injection.

Neurologic erectile dysfunction

Neurologic erectile dysfunction presents a diagnostic and treatment challenge to the internist and urologist. Multiple chronic disease modalities and traumatic etiologies exist. Education regarding these conditions and a detailed and thorough history and office work-up are the best resources for the clinician. Treatment can follow the model of proceeding from the least to most invasive procedure (process of care), taking into account patient and partner satisfaction. Because the psychology of grief and loss may enter into treatment of some neurologic conditions (e.g., erectile dysfunction after radical retropubic prostatectomy, spinal cord injury, or chronic diseases), a whole-patient approach encompassing psychotherapy is warranted.
