What Is a "Validated Questionnaire"? A Critical Review of Erectile Function Assessment

Variability in Methodology of Erectile Dysfunction Regenerative Therapy Trials on ClinicalTrials.gov

OBJECTIVE

To evaluate the variability in the criteria of erectile dysfunction (ED) regenerative therapy trials registered on ClinicalTrials.gov.

METHODS

Interventional trials on ClinicalTrials.gov with the keywords "erectile dysfunction" and variations of "shockwave," "platelet rich plasma," "stem cell," "regenerative," and "restorative" were examined. Inclusion/exclusion criteria and primary/secondary outcomes were compared between extracorporeal shockwave therapy (ESWT), platelet rich plasma and stem cell injections (PRP/SC), and other regenerative therapies (ORT) groups.

RESULTS

Of the 92 trials analyzed, International Index of Erectile Function (IIEF) score was the most common primary outcome (72%), with a higher prevalence in ESWT trials than PRP/SC or ORT trials (89% vs 44% and 58%, P <.001). Safety/tolerability was a primary outcome for 44% of PRP/SC trials and 25% of ORT trials but no ESWT trials (P <.001). ESWT trials more frequently had sexual/romantic relationship-based inclusion criteria and cancer treatment-related exclusion criteria than PRP/SC and ORT trials.

CONCLUSION

There is substantial variability in the inclusion/exclusion criteria and outcome measures among ED regenerative therapy trials. ESWT trials most frequently utilized IIEF and had the strictest inclusion/exclusion criteria, suggesting more rigorous and functional outcome-based studies. Conversely, PRP/SC and ORT trials, but not ESWT trials, had safety/tolerability as a primary outcome, likely due to the experimental nature of these therapies. The variability in inclusion/exclusion criteria and outcome measures limits comparison of the various ED regenerative therapies.

MRI-Cavernosography: A New Diagnostic Tool for Erectile Dysfunction Due to Venous Leakage: A Diagnostic Chance

Erectile dysfunction caused by venous leakage is a vascular disease in which blood fails to accumulate in the corpora cavernosa due to the abrupt drainage of blood from the penis secondary to an abnormal venous network that affects 1 to 2% of men under 25 years old and about 10 to 20% over 60 years old, who do not raise a sufficient erection for penetrative sex. The study of the venous leak and its characterization in young patients with erectile dysfunction represent a diagnostic challenge, and imaging remains the best way to diagnose this condition. In the article, it is described the methods of execution and the diagnostic role of the cavernous MRI in the study of vasogenic erectile dysfunction from the venous leak, proposing it as a good alternative to the cavernous CT, considering the satisfactory results in terms of diagnostic interpretation, the absence of ionizing radiation, the higher soft tissue resolution of the imaging method and the lower administration of contrast agent.

Management of erectile dysfunction and premature ejaculation: The perspective of Spanish urologists. Results of the PANDORA Project (Part II)

INTRODUCTION

ED and PE are the most common male sexual dysfunctions, although they remain underdiagnosed and undertreated.

AIM

To ascertain how a group of Spanish urologists currently address ED and PE.

METHODS

Descriptive study based on a self-designed questionnaire about the clinical practice in ED and PE upon diagnosis, treatment and monitoring, patient-physician relationship and the role of the patient's partner.

RESULTS

The survey was completed by 188 experienced urologists. Most patients went to the urologist's office without a previous diagnosis (92% of the urologists found <10 PE-diagnosed patients in public settings). The diagnosis of ED and/or PE was mainly carried out by the current urologist and not by another professional, particularly in private centres as opposed to public centres (78.8% vs 57.0% for ED; 82.0% vs 62.6% for PE). Most urologists believed that these disorders are underdiagnosed and deemed them as general health issues. 38% of urologists acknowledged using validated questionnaires to diagnose ED. PE was considered a subjective problem rather than a true disease and the use of PRO-based diagnosis of PE was not generally accepted (14%). Treatment options of both disorders were chosen as expected. Referral to the andrologist is usually scheduled in moderate-to-severe PE or severe ED. The cohort seemed to be mostly neutral (50%-75% for ED and 40%-55% for PE) regarding patient reluctancy to talk about their sexual problem. Patients' partners play an important role in helping men seeking treatment.

CONCLUSION

Urologists should show more proactivity during anamnesis and routine visits to improve management of ED and PD.

Sexuality, Intimacy, and Reproductive Health after Spinal Cord Injury

Spinal cord injury (SCI) is a life-altering event often accompanied by a host of anxiety-provoking questions and concerns in the minds of affected individuals. Questions regarding the ability to resume sexual activity, partner's satisfaction as well as the ability to have biological children are just a few of the unknowns facing patients following the devastating reality that is SCI. As a result of advances in SCI research over the last few decades, providers now have the knowledge and tools to address many of these concerns in an evidence-based and patient-centered approach. SCI can impair multiple components involved in sexual function, including libido, achieving and maintaining an erection, ejaculation, and orgasm. Many safe and effective fertility treatments are available to couples affected by SCI. Finally, learning to redefine one's self-image, reinforce confidence and self-esteem, and feel comfortable communicating are equally as important as understanding functionality in regaining quality of life after SCI. Thus, this review aims to highlight the current state of SCI research relating to sexual function, reproductive health, and the search for meaning.

A Historical and Contemporary Review of Questionnaires Used in the Management of Post-Radical Prostatectomy Patients

INTRODUCTION

Patients undergoing radical prostatectomy (RP) face obstacles to recovery spanning the domains of erectile and sexual function; urinary function; and health-related quality of life (HRQoL). Numerous patient-directed questionnaires exist that serve to assist in the care of these men.

AIM

To describe patient-directed questionnaires of historical and contemporary relevance involving the evaluation and treatment of men after radical prostatectomy.

METHODS

A comprehensive review of peer-reviewed publications on the topic was performed. Using PubMed, the search terms used were: "radical prostatectomy; erectile function; lower urinary tract symptoms; sexual dysfunction; urinary incontinence; and health-related quality of life.

MAIN OUTCOME MEASURE

We aimed to summarize questionnaires and survey devices of historical and contemporary importance for the care of men after RP.

RESULTS

Many questionnaires have been developed specifically for, or conscripted for use in, the care of men after RP. Some of the oldest questionnaires relating to sexual function, urinary function, and general and cancer-specific QoL are important and still utilized in the routine clinical care of post-RP patients. However, recent devices that may offer clinicians a more comprehensive understanding to aid in the evaluation and care of these men.

CONCLUSIONS

Post-RP patients face numerous challenges that require a thoughtful approach, one that is broad enough to identify a variety of potential physical and emotional disturbances, yet granular enough to identify appropriate areas for intervention. While there is not a "best" questionnaire for this population, having an appropriate understanding of the current available instruments and what information they provide may help clinicians more thoroughly assess and treat these men.

Sexual function criteria post laparoscopic radical prostatectomy: a reverse systematic review

OBJECTIVE

To apply a new review methodology, called reverse systematic review (RSR), to assess how different classification criteria can influence erectile dysfunction rates in patients undergoing laparoscopic radical prostatectomy (LRP).

METHODS

We used RSR from January 1, 2000, until December 31, 2020. The post-prostatectomy erectile dysfunction (PPED) rates were evaluated at 1, 3, 6, 12, and 18 months after surgery in different criteria selected as the most commonly used and divided into four groups: "Erection Sufficient for Intercourse (ESI)", "IIEF-5 > 17", "IIEF-5 > 22" and "Not Available". Temporal distribution of different criteria was analyzed to identify patterns throughout the "natural history" of LRP.

RESULTS

40 systematic reviews on LRP evaluated 81 cohorts and 21,618 patients on PPED. ESI was the predominant form of PPED evaluation (75.3%) followed by IIEF-5 > 22 (11.1%). Despite being a simpler criterion, ESI showed worse PPED rates at 1, 3, 6 and 12 months (8%, 27%, 43% and 51%) than IIEF-5 > 22 (14%, 26%, 45% and 58%). The studies were published between 2005 and 2015, but it was in 2010 that the ESI criterion was established as predominant in the literature, reducing the application of others.

CONCLUSION

The RSR has proven effective in demonstrating how the PPED evaluation criteria behaved in the "natural history" of the LRP. It showed how a simple and easy-to-apply criterion, such as the ESI, was preferred by the authors, even showing worse PPED rates than other more complex.

A Natural History of Erectile Dysfunction in Elderly Men: A Population-Based, Twelve-Year Prospective Study

There is a wide variation in the development and course of erectile dysfunction (ED) in men, which confirms the need for prospective studies. We conducted a cross-sectional analysis among the general male population at the baseline (n = 359) and in a follow-up survey (n = 218) 12 years later. The prospective 12-year study included 189 men. ED was assessed using the International Index of Erectile Function questionnaire. The mean age of the participants was 62.0 years at the baseline, while at the 12-year follow-up it was 71.6 years. The crude prevalence of ED was 61.6% at the baseline and 78.9% at the follow-up, and the prevalence tended to increase with age. All of the men aged 75 years or more had at least mild ED. The incidence of ED in every thousand person years was 53.5. A total of 54.5% of the men experienced ED progression, while 39.2% reported no changes in erectile function, and 6.3% experienced ED regression during the 12-year study. The likelihood of ED progression was higher in the older compared with younger age group (odds ratio, OR 5.2 (95% CI: 1.1-26.2)), and the likelihood of ED regression was lower among men with increased depression symptoms (OR 0.3 (95% CI: 0.1-0.6)) and among men with a decreased interest in their sexual life (OR 0.1 (95% CI: 0.0-0.6)). Lifestyle factors such as the consumption of alcohol and smoking were not significantly associated with ED.

Erectile dysfunction and penile rehabilitation after pelvic fracture: a systematic review and meta-analysis

OBJECTIVE

To investigate the rate of erectile dysfunction (ED) after pelvic ring fracture (PRF).

DESIGN

Systematic review and meta-analysis.

METHODS

A systematic literature search of the Cochrane, EMBASE, MEDLINE, Scopus and Web of Science Library databases was conducted in January 2020. Included were original studies performed on humans assessing ED after PRF according to the 5-item International Index of Erectile Function (IIEF-5) questionnaire and fracture classification following Young and Burgess, Tile or Arbeitsgemeinschaft für Osteosynthesefragen/Orthopedic Trauma Association. Furthermore, interventional cohort studies assessing the effect of penile rehabilitation therapy with phosphodiesterase-5-inhibitors (PDE-5-I) on IIEF-5 scores compared before and after treatment were included. Results were presented as forest plots of proportions of patients with ED after PRF or mean changes on IIEF-5 questionnaires before and after penile rehabilitation. Studies not included in the quantitative analysis were narratively summarised. Risk of bias assessment was conducted using the revised tool for the Quality Assessment on Diagnostic Accuracy Studies.

RESULTS

The systematic literature search retrieved 617 articles. Seven articles were included in the qualitative analysis and the meta-analysis. Pooled proportions revealed 37% of patients with ED after suffering any form of PRF (result on probability scale pr=0.37, 95% CI: 0.26 to 0.50). Patients after 3 months of penile rehabilitation therapy reported a higher IIEF-5 score than before (change score=6.5 points, 95% CI: 2.54 to 10.46, p value=0.0013).

CONCLUSION

Despite some heterogeneity and limited high-quality research, this study concludes that patients suffering from any type of PRF have an increased risk of developing ED. Oral intake of PDE-5-I for the purpose of penile rehabilitation therapy increases IIEF-5 scores and may relevantly influence quality-of-life in these patients.

Current Status for Semirigid Penile Prosthetic Devices

PURPOSE OF REVIEW

The goal of this paper was to evaluate the current use of semirigid penile prosthesis (SRPP), surgical techniques for insertion of SRPP, and how to prevent and approach surgical complications.

RECENT FINDINGS

SRPP is a valid option for those who are refractory to medical therapy for erectile dysfunction (ED) and even more appropriate for specific subsets of patient populations. It is important for urologists to know which patient population SRPP is preferred for. Several studies have shown good patient outcomes and patient satisfaction with those who underwent SRPP.

Sexual Dysfunction Among Men Who Have Sex with Men: a Review Article

PURPOSE OF REVIEW

The goal of this review article is to evaluate sexual dysfunction among men who have sex with men (MSM).

RECENT FINDINGS

Men who have sex with men are commonly affected by sexual dysfunction. Often sexual dysfunction in MSM will significantly impact their psychological well-being perhaps even more than their heterosexual counterparts. Despite the frequency and high impact of sexual dysfunction in MSM, access to appropriate care may be limited. It is important for urologists, especially sexual medicine clinicians, to be aware of and comfortable with differences in sexual practices of MSM. Penile pathology in this patient population will negatively affect their quality of life and well-being. Therefore, it is important to properly assess and treat these patients.

[Decision regret analysis among Chinese patients receiving penile girth enhancement with acellular dermal matrix]

OBJECTIVE

To evaluate decision regret among patients receiving penile girth enhancement with acellular dermal matrix (PGE with ADM) and to investigate the potential indicators for decisional regret so as to facilitate the decision-making process for this special group.

METHODS

In the study, 78 patients receiving PGE with ADM from Jun. 2016 to Jan. 2019 at Peking University People's Hospital and cooperative hospitals were eligible. Penile girth was taken by only one surgeon 1 week before surgery. Hospital anxiety and depression scale (HAD), international index of erectile function (IIEF) and a 10 cm long visual analogue scale named visualized penile image (VPI) were applied to measure psychological burden, erectile function and satisfaction with penile image respectively at the same time. All the patients were followed up for 3 months. Decision regret scale (DRS) was adopted for measuring decisional regret. Multivariate analysis of variance was applied to investigate the potential indicators for regret. Data analysis process was conducted with SPSS (version 24.0; SPSS, Chicago, IL, USA).

RESULTS

Mean penile girth recorded before intervention was (8.29±0.30) cm and increased to (9.46±0.29) cm post surgery (t=76.28, P < 0.01). As for both subscales of HAD measuring psychological burden, a signi-ficant reduction in the mean score was seen, that is, 2.8±1.3 (t=19.28, P < 0.05) for anxiety and 3.0±1.2 (t=20.67, P < 0.05) for depression, respectively. The average score of VPI increased by 3.7±1.1 (t=30.63, P < 0.05). There was no significant change in the average score of IIEF measuring erectile satisfaction (t=1.60, P=0.11). Twenty-nine (38.2%) patients expressed regret to some degree, and the mean DRS score was 23.4±14.8. The scores of DRS correlated negatively with scores of visualized penis image (r=-0.348, P < 0.01), and positively with scores of anxiety (r=0.760, P < 0.01) and depression subscale (r=0.471, P < 0.01). The scores of DRS was irrelevant to those of IIEF (r=0.02, P=0.867). The patients with high annual income (> 120 000 yuan) and education level above undergraduate were more prone to experience decision regret after intervention (P < 0.01).

CONCLUSION

PGE with ADM did augment penile girth and lower psychological burden, the regret rate of which was acceptably low among the patients. High income and good education might indicate more post-operative regret. Additional decision-making aids should be offered to patients with high income and education level above high school.
