Control4Life: A randomized controlled trial protocol examining the feasibility and efficacy of a combined pelvic health rehabilitation and exercise fitness program for individuals undergoing prostatectomy

BACKGROUND

Urinary incontinence (UI), erectile dysfunction and cardiometabolic conditions are common after prostatectomy for prostate cancer (PCa). Although physical activity could improve overall survival and quality of survivorship, fear of UI can restrict participation in exercise. Individuals with PCa could benefit from therapeutic exercise programming to support continence recovery and cardiometabolic health.

AIM

The main objective of this study is to determine the feasibility and the effects of a combined pelvic health rehabilitation and exercise fitness program on UI after prostatectomy. The combined exercise program will be delivered both in-person and virtually.

METHODS

This study follows a modified Zelen, two-arm parallel randomized controlled trial design. A total of 106 individuals with PCa will be recruited before prostatectomy surgery. Participants will be randomized between two groups: one receiving usual care and one receiving a combined exercise fitness and intensive pelvic floor muscle training program. Exercise programming will begin 6-8 weeks after prostatectomy and will last 12 weeks. Outcomes include: the 24-h pad test (primary outcome for UI); physical fitness, metabolic indicators, and patient-reported outcomes on erectile function, self-efficacy, severity of cancer symptoms and quality of life. Important timepoints for assessments include before surgery (T0), after surgery (T1), after intervention (T3) and at one-year after surgery (T4).

CONCLUSION

This study will inform the feasibility of offering comprehensive exercise programming that has the potential to positively impact urinary continence, erectile function and cardiometabolic health of individuals undergoing prostatectomy for prostate cancer.

Optimal vacuum erectile device therapy regimen for penile rehabilitation in a bilateral cavernous nerve crush rat model

BACKGROUND

Vacuum erectile device (VED) therapy has been widely used in penile rehabilitation after radical prostatectomy; however, there is no consensus on the best regimen.

OBJECTIVES

To explore an optimal VED therapy regimen in bilateral cavernous nerve crush (BCNC) rat model.

MATERIALS AND METHODS

Adult male rats were used to measure the effects of different durations (1-30 min) of VED treatment on penile length, penile blood gas analysis, and adverse effects. Forty-eight adult male rats were randomly divided into Sham, BCNC, and VED treatment groups (2-3-2-3 min, 4-3-3 min, 5-5 min, and 10 min). Penile length, erectile function, and side effects were detected after VED treatment. Histopathological staining and Western blotting were performed to explore the cellular and molecular changes.

RESULTS

Prolongation of the duration of VED treatment significantly decreased the penile oxygen saturation, partial oxygen pressure, and arterial blood ratio (P < 0.05). Compared with the BCNC group, all VED treatment regimens partially reversed BCNC-induced penile shortening and erectile dysfunction (P < 0.0001), with the 4-3-3-min and 5-5-min treatment groups exhibiting more significant improvement than the 10-min and 2-3-2-3-min treatment groups (P < 0.0001). The mechanism may be related to the up-regulation of the smooth muscle cell/collagen ratio, endothelial nitric oxide synthase, and α-smooth muscle actin (all P < 0.0001); and the down-regulation of hypoxia-inducible factor-1α, transforming growth factor-β1, and apoptosis (all P < 0.0001). The incidence of adverse effects in the 2-3-2-3-min treatment group was the highest.

DISCUSSION

The commonly used VED therapy regimens maintained erectile function and penile length of BCNC rat by relieving hypoxia and fibrosis, and no further benefits were observed with increased treatment frequency or prolonged treatment duration.

CONCLUSION

Two consecutive 5-min treatments with a short interval is the optimal VED therapy regimen for penile rehabilitation in BCNC rat model.

Acceptance and Commitment Therapy to Increase Adherence to Penile Injection Therapy-Based Rehabilitation After Radical Prostatectomy: Pilot Randomized Controlled Trial

INTRODUCTION

Despite the importance of using penile injections as part of a penile rehabilitation program, men have difficulty complying with these programs.

AIM

To test a novel psychological intervention based on Acceptance and Commitment Therapy for erectile dysfunction (ACT-ED) to help men utilize penile injections.

METHODS

This pilot randomized controlled trial (RCT) recruited men who were beginning a standard care (SC) structured penile rehabilitation program following radical prostatectomy. The SC program instructed patients to use penile injections 2 to 3 times per week. Participants were randomized to SC+ACT-ED or SC+enhanced monitoring (EM). Over 4 months, patients in the SC+ACT-ED group received SC plus 4 ACT sessions and 3 ACT phone calls; those in the EM group received SC plus 7 phone calls from an experienced sexual medicine nurse practitioner. Participants were assessed at study entry and at 4 and 8 months. For this pilot study, the goal was to determine initial efficacy (ie, effect sizes, where d = 0.2 is small, d = 0.5 is medium, and d = 0.8 is large).

MAIN OUTCOME MEASURE

Primary outcomes were feasibility and use of penile injections. Secondary outcomes were ED treatment satisfaction (ie, Erectile Dysfunction Inventory of Treatment Satisfaction, or EDITS), sexual Self-Esteem and Relationship (SEAR) quality, sexual bother (SB), and prostate cancer treatment regret.

RESULTS

The 53 participants were randomized (ACT, n = 26; EM, n = 27). The study acceptance rate was 61%. At 4 months, the ACT-ED group utilized more penile injections per week (1.7) compared to the EM group (0.9) (d = 1.25; P = .001) and was more adherent to penile rehabilitation compared to the EM group (ACT, 44%; EM, 10%; relative risk [RR], 4.4; P = .02). These gains were maintained at 8 months for injections per week (ACT, 1.2; EM, 0.7; d = 1.08; P = .03) and approached significance for adherence (ACT, 18%; EM, 0%; P = .10). At 4 months, ACT-ED, compared to EM, reported moderate effects for greater satisfaction with ED treatment (d = 0.41; P = .22), greater sexual self-esteem (d = 0.54; P = .07) and sexual confidence (d = 0.48; P = .07), lower sexual bother (d = 0.43; P = .17), and lower prostate cancer treatment regret (d = 0.74; P = .02). At 8 months, moderate effects in favor of ACT-ED were maintained for greater sexual self-esteem (d = 0.40; P = .19) and less treatment regret (d = 0.47; P = .16).

CLINICAL IMPLICATIONS

ACT concepts may help men utilize penile injections and cope with the effects of ED.

STRENGTHS AND LIMITATIONS

Strengths include use of an innovative intervention utilizing ACT concepts and pilot RCT. Limitations include the pilot nature of the study (eg, small samples size, lack of statistical power).

CONCLUSION

ACT-ED is feasible and significantly increases the use of penile injections. ACT-ED also shows promise (moderate effects) for increasing satisfaction with penile injections and sexual self-esteem while decreasing sexual bother and prostate cancer treatment regret.

[Attitudes of prostate cancer patients towards postoperative penile rehabilitation and their influencing factors]

OBJECTIVE

To investigate the attitudes of prostate cancer (PCa) patients towards postoperative penile rehabilitation and their influencing factors.

METHODS

Seventy-nine PCa patients underwent radical prostatectomy from January through June 2017 and all received a questionnaire investigation before surgery on IIEF-5 and their attitudes towards postoperative penile rehabilitation. We analyzed the reasons for the patients' rejection of postoperative penile rehabilitation.

RESULTS

Totally 56 (71%) of the patients accepted and the other 23 (29%) refused postoperative penile rehabilitation. The factors influencing their attitudes towards penile rehabilitation mainly included age (P = 0.023), income (P = 0.040), tumor stage (P = 0.044), and preoperative sexual activity (P = 0.004). The patients who accepted penile rehabilitation had significantly higher IIEF-5 scores than those who refused it (14.75 ± 0.88 vs 8.48 ± 1.16, P = 0.000 2). During the follow-up period, only 29 (36.7%) of the patients bought the vacuum erection device but not the other 50 (63.3%). The tumor stage (P = 0.004), income (P < 0.01) and preoperative androgen-deprivation therapy (P = 0.039) significantly influenced the patients' decision on the purchase of the device. Relevant admission education achieved a 45% decrease in the number of the patients unwilling to accept penile rehabilitation for worrying about its negative effect on cancer treatment, a 25% decrease in those rejecting penile rehabilitation because of age, and a 20% decrease in those refusing it due to the tumor stage. The cost of treatment was an important reason for the patients' rejection of postoperative penile rehabilitation.

CONCLUSIONS

The tumor stage and income are the main factors influencing PCa patients' decision on postoperative penile rehabilitation. Relevant admission education and reduced cost of rehabilitation are important for popularization of postoperative penile rehabilitation in PCa patients.

The Early Use of Vacuum Therapy for Penile Rehabilitation After Radical Prostatectomy: Systematic Review and Meta-Analysis

Vacuum therapy has been widely used for penile rehabilitation after radical prostatectomy (RP), but its efficacy and safety are unclear. The study was to evaluate the efficacy and safety of the early use of vacuum therapy for post-RP men. Randomized clinical trials were selected according to predefined inclusion and exclusion criteria. RevMan 5.3 software was used for meta-analyses. In total, six randomized controlled trials were included with a total of 273 post-RP patients. The meta-analysis revealed that the early use of vacuum therapy could significantly improve the five-item International Index of Erectile Function and penile shrinkage in post-RP patients. Few adverse events were reported across the included studies. This review suggests that the early use of vacuum therapy appears to have excellent therapeutic effect on post-RP patients and no serious side effects were identified. Due to overall limited quality of the included studies, the therapeutic benefit of vacuum therapy in penile rehabilitation needs be substantiated to a limited degree in the future. Better methodological, large controlled trials are expected to verify the therapeutic effect of vacuum therapy in penile rehabilitation.

Penile rehabilitation for postprostatectomy erectile dysfunction

BACKGROUND

Despite efforts to preserve the neurovascular bundles with nerve-sparing surgery, erectile dysfunction remains common following radical prostatectomy. Postoperative penile rehabilitation seeks to restore erectile function but results have been conflicting.

OBJECTIVES

To evaluate the effects of penile rehabilitation strategies in restoring erectile function following radical prostatectomy for prostate cancer.

SEARCH METHODS

We performed a comprehensive search of multiple databases (CENTRAL, MEDLINE, Embase), the Cochrane Library, Web of Science, clinical trial registries (ClinicalTrials.gov, International Clinical Trials Registry Platform) and a grey literature repository (Grey Literature Report) from their inception through to 3 January 2018. We also searched the reference lists of other relevant publications and abstract proceedings. We applied no language restrictions.

SELECTION CRITERIA

We included randomised or quasi-randomised trials with a parallel or cross-over design.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodological procedures. Two review authors independently screened the literature, extracted data, assessed risk of bias and rated quality of evidence according to GRADE on a per-outcome basis. Primary outcomes were self-reported potency, erectile function measured by validated questionnaires (with potency defined as an International Index of Erectile Function (IIEF-EF) score of 19 or greater and or an IIEF-5 of score of 17 or greater) and serious adverse events. For all quality of life assessments on a continuous scale, higher values indicated better quality of life.

MAIN RESULTS

We included eight randomised controlled trials with 1699 participants across three comparisons. This abstract focuses on the primary outcomes of this review only.Scheduled phosphodiesterase type 5 inhibitors (PDE5I) versus placebo or no treatmentScheduled PDE5I may have little or no effect on short-term (up to 12 months) self-reported potency (risk ratio (RR) 1.13, 95% confidence interval (CI) 0.91 to1.41; very low quality evidence), which corresponds to 47 more men with self-reported potency per 1000 (95% CI 33 fewer to 149 more) and short-term erectile function as assessed by a validated instrument (RR 1.11, 95% CI 0.80 to 1.55; very low quality evidence), which corresponds to 28 more men per 1000 (95% CI 50 fewer to 138 more), but we are very uncertain of both of these findings. Scheduled PDE5I may result in fewer serious adverse events compared to placebo (RR 0.32, 95% CI 0.11 to 0.94; low quality evidence), though this does not appear biologically plausible and may represent a chance finding. We are also very uncertain of this finding. We found no long-term (longer than 12 months) data for any of the three primary outcomes.Scheduled PDE5I versus on-demand PDE5I Daily PDE5I appears to result in little to no difference in both short-term and long-term (greater than 12 months) self-reported potency (short term: RR 0.97, 95% CI 0.62 to 1.53; long term: RR 1.00, 95% CI 0.60 to 1.67; both very low quality evidence); this corresponds to nine fewer men with self-reported short-term potency per 1000 (95% CI 119 fewer to 166 more) and zero fewer men with self-reported long-term potency per 1000 (95% CI 153 fewer to 257 more). We are very uncertain of these findings. Daily PDE5I appears to result in little to no difference in short-term and long-term erectile function (short term: RR 1.00, 95% CI 0.65 to 1.55; long term; RR 0.74, 95% CI 0.48 to 1.14; both very-low quality evidence), which corresponds to zero men with short-term erectile dysfunction per 1000 (95% CI 80 fewer to 125 more) and 119 fewer men with long-term erectile dysfunction per 1000 (95% CI 239 fewer to 64 more). We are very uncertain of these findings. Scheduled PDE5I may result in little or no effects on short-term adverse events (RR 0.69 95% CI 0.12 to 4.04; very low quality evidence), which corresponds to seven fewer men with short-term serious adverse events (95% CI 18 fewer to 64 more), but we are very uncertain of these findings. We found no long-term data for serious adverse events.Scheduled PDE5I versus scheduled intraurethral prostaglandin E1At short-term follow-up, daily PDE5I may result in little or no effect on self-reported potency (RR 1.10, 95% CI 0.79, to 1.52; very low quality evidence), which corresponds to 46 more men per 1000 (95% CI 97 fewer to 241 more). Daily PDE5I may result in a small improvement of erectile function (RR 1.64, 95% CI 0.84 to 3.20; very low quality evidence), which corresponds to 92 more men per 1000 (95% CI 23 fewer to 318 more) but we are very uncertain of both these findings. We found no long-term (longer than 12 months) data for any of the three primary outcomes.We found no evidence for any other comparisons and were unable to perform any of the preplanned subgroup analyses based on nerve-sparing approach, age or baseline erectile function.

AUTHORS' CONCLUSIONS

Based on mostly very-low and some low-quality evidence, penile rehabilitation strategies consisting of scheduled PDE5I use following radical prostatectomy may not promote self-reported potency and erectile function any more than on demand use.

[Value of non-sexual penile erection for penile rehabilitation in men with erectile dysfunction]

Erectile dysfunction (ED) is a common male disease. Some related studies show that the prevalence of ED is nearly 52% in men aged 40 to 70 years and is increasing among younger males. Hypoxia is now considered to be an independent risk factor for ED and the mechanisms of hypoxia inducing ED are varied and complicated. Recently, an idea in penile rehabilitation has attracted much attention, which aims at improving erectile function by increasing oxygen supply to the cavernosum and reducing tissue fibrosis and apoptosis. The approaches to achieve non-sexual penile erection by increasing oxygen supply to the cavernosum, such as behavior therapy, medication, vacuum constriction device, and intracavernous injection, can simulate normal sexual erection and help patients with penile rehabilitation. This review focuses on the strategies for non-sexual penile erection in penile rehabilitation.

Erectile Dysfunction

Erectile dysfunction (ED) is the inability to achieve or maintain an erection sufficient for satisfactory sexual performance. It is common, affecting at least 12 million U.S. men. The five-question International Index of Erectile Function allows rapid clinical assessment of ED. The condition can be caused by vascular, neurologic, psychological, and hormonal factors. Common conditions related to ED include diabetes mellitus, hypertension, hyperlipidemia, obesity, testosterone deficiency, and prostate cancer treatment. Performance anxiety and relationship issues are common psychological causes. Medications and substance use can cause or exacerbate ED; antidepressants and tobacco use are the most common. ED is associated with an increased risk of cardiovascular disease, particularly in men with metabolic syndrome. Tobacco cessation, regular exercise, weight loss, and improved control of diabetes, hypertension, and hyperlipidemia are recommended initial lifestyle interventions. Oral phosphodiesterase-5 inhibitors are the firstline treatments for ED. Second-line treatments include alprostadil and vacuum devices. Surgically implanted penile prostheses are an option when other treatments have been ineffective. Counseling is recommended for men with psychogenic ED.

[Penile rehabilitation after radical pelvic surgery]

Prostate cancer, bladder cancer, and rectal cancer are common malignancies in the male pelvis. The incidence rate of erectile dysfunction (ED) following radical prostatectomy, cystectomy or rectal cancer surgery is about 25% - 100%. The main cause of post-surgery ED is mainly attributed to injury of neurovascular bundles, which may lead to reduced oxygenation in and fibrosis of the penile tissue. Early penile rehabilitation after surgery can improve or restore the erectile function of the patients. This article focuses on penile rehabilitation after radical pelvic surgery.

[Application of the vacuum erectile device in penile rehabilitation for erectile dysfunction after radical prostatectomy]

The vacuum erectile device (VED) uses negative pressure to increase blood inflow into the corpora cavernosum, with a ring at the base of the penis to maintain erection for intercourse or without a ring for penile rehabilitation. Owing to the limitation of phosphodiesterase 5 inhibitors (PDE5I) shown in the treatment of refractory erectile dysfunction (ED), the use of VED has resurged and is becoming the first line therapy in the treatment of ED following radical prostatectomy (RP). Currently, the combination therapy of VED with PDE5I and that of VED with intracavernous injection are advocated for post-RP ED. Hereby, we review the role of VED in penile rehabilitation, its underlying mechanisms, and the combination therapies for it.

Penile rehabilitation after pelvic cancer surgery

Erectile dysfunction is the most common complication after pelvic radical surgery. Rehabilitation programs are increasingly being used in clinical practice but there is no high level of evidence supporting its efficacy. The principle of early penile rehabilitation stems from animal studies showing early histological and molecular changes associated with penile corporal hypoxia after cavernous nerve injury. The concept of early penile rehabilitation was developed in late nineties with a subsequent number of clinical studies supporting early pharmacologic penile rehabilitation. These studies included all available phosphodiesterase type 5 inhibitors, intracavernosal injection and intraurethral use of prostaglandin E1 and to lesser extent vacuum erectile devices. However, these studies are of small number, difficult to interpret, and often with no control group. Furthermore, no studies have proven an in vivo derangement of endothelial or smooth muscle cell metabolism secondary to a prolonged flaccid state. The purpose of the present report is a synthetic overview of the literature in order to analyze the concept and the rationale of rehabilitation program of erectile dysfunction following radical pelvic surgery and the evidence of such programs in clinical practice. Emphasis will be placed on penile rehabilitation programs after radical cystoprostatectomy, radical prostatectomy, and rectal cancer treatment. Future perspectives are also analyzed.

Conservative management for postprostatectomy urinary incontinence

BACKGROUND

Urinary incontinence is common after radical prostatectomy and can also occur in some circumstances after transurethral resection of the prostate (TURP). Conservative management includes pelvic floor muscle training with or without biofeedback, electrical stimulation, extra-corporeal magnetic innervation (ExMI), compression devices (penile clamps), lifestyle changes, or a combination of methods.

OBJECTIVES

To determine the effectiveness of conservative management for urinary incontinence up to 12 months after transurethral, suprapubic, laparoscopic, radical retropubic or perineal prostatectomy, including any single conservative therapy or any combination of conservative therapies.

SEARCH METHODS

We searched the Cochrane Incontinence Group Specialised Register (5 February 2014), CENTRAL (2014, Issue 1), EMBASE (January 2010 to Week 3 2014), CINAHL (January 1982 to 18 January 2014), ClinicalTrials.gov and World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (both searched 29 January 2014), and the reference lists of relevant articles.

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials evaluating conservative interventions for urinary continence in men after prostatectomy.

DATA COLLECTION AND ANALYSIS

Two or more review authors assessed the methodological quality of the trials and abstracted data. We tried to contact several authors of included studies to obtain extra information.

MAIN RESULTS

Fifty trials met the inclusion criteria, 45 in men after radical prostatectomy, four trials after TURP and one trial after either operation. The trials included 4717 men of whom 2736 had an active conservative intervention. There was considerable variation in the interventions, populations and outcome measures. Data were not available for many of the pre-stated outcomes. Men's symptoms improved over time irrespective of management.There was no evidence from eight trials that pelvic floor muscle training with or without biofeedback was better than control for men who had urinary incontinence up to 12 months after radical prostatectomy; the quality of the evidence was judged to be moderate (for example 57% with urinary incontinence in the intervention group versus 62% in the control group, risk ratio (RR) for incontinence after 12 months 0.85, 95% confidence interval (CI) 0.60 to 1.22). One large multi-centre trial of one-to-one therapy showed no difference in any urinary or quality of life outcome measures and had narrow CIs. It seems unlikely that men benefit from one-to-one PFMT therapy after TURP. Individual small trials provided data to suggest that electrical stimulation, external magnetic innervation, or combinations of treatments might be beneficial but the evidence was limited. Amongst trials of conservative treatment for all men after radical prostatectomy, aimed at both treatment and prevention, there was moderate evidence of an overall benefit from pelvic floor muscle training versus control management in terms of reduction of urinary incontinence (for example 10% with urinary incontinence after one year in the intervention groups versus 32% in the control groups, RR for urinary incontinence 0.32, 95% CI 0.20 to 0.51). However, this finding was not supported by other data from pad tests. The findings should be treated with caution because the risk of bias assessment showed methodological limitations. Men in one trial were more satisfied with one type of external compression device, which had the lowest urine loss, compared to two others or no treatment. The effect of other conservative interventions such as lifestyle changes remained undetermined as no trials involving these interventions were identified.

AUTHORS' CONCLUSIONS

The value of the various approaches to conservative management of postprostatectomy incontinence after radical prostatectomy remains uncertain. The evidence is conflicting and therefore rigorous, adequately powered randomised controlled trials (RCTs) which abide by the principles and recommendations of the CONSORT statement are still needed to obtain a definitive answer. The trials should be robustly designed to answer specific well constructed research questions and include outcomes which are important from the patient's perspective in decision making and are also relevant to the healthcare professionals. Long-term incontinence may be managed by an external penile clamp, but there are safety problems.

Development of UK recommendations on treatment for post-surgical erectile dysfunction

AIM

To develop a management strategy (rehabilitation programme) for postsurgical erectile dysfunction (ED) among men experiencing ED associated with treatment of prostate, bladder or rectal cancer that is suitable for use in a UK NHS healthcare context.

METHODS

PubMed literature searches of ED management together with a survey of 13 experts in the management of ED from across the UK were conducted.

RESULTS

Data from 37 articles and completed questionnaires were collated. The results discussed in this study demonstrate improved objective and subjective clinical outcomes for physical parameters, sexual satisfaction, and rates of both spontaneous erections and those associated with ED treatment strategies.

CONCLUSION

Based on the literature and survey analysis, recommendations are proposed for the standardisation of management strategies employed for postsurgical ED.

Inflatable penile prostheses for the treatment of erectile dysfunction

Male erectile dysfunction is a common medical condition. Recent advances in our understanding of corpora cavernosa physiology have resulted in three effective oral medications (sildenafil, vardenafil and tadalafil--all phosphodiesterase type 5 inhibitors), which can effectively treat many men with erectile dysfunction. However, a large number of men are not adequately treated by these medications due to their cost, side effects, contraindications or lack of a satisfactory erectile response. For men who do not respond to less invasive therapy, an inflatable penile prosthesis can provide an excellent alternative. This article will review and critique the currently available inflatable penile prostheses in the treatment of erectile dysfunction.

Exploring gay couples' experience with sexual dysfunction after radical prostatectomy: a qualitative study

This exploratory study examines the experience of three gay couples managing sexual dysfunction as a result of undergoing a radical prostatectomy. Semi-structured interviews were conducted as part of a larger study at an urban hospital in Toronto, Ontario, Canada. Interview transcripts were transcribed verbatim, and analyzed using interpretative phenomenological analysis. The authors clustered 18 subordinate themes under 3 superordinate themes: (a) acknowledging change in sexual experience (libido, erectile function, sexual activity, orgasmic function); (b) accommodating change in sexual experience (strategies: emphasizing intimacy, embracing plan B, focus on the other; barriers: side-effect concerns, loss of naturalness, communication breakdown, failure to initiate, trial and failure, partner confounds); and (c) accepting change in sexual experience (indicators: emphasizing health, age attributions, finding a new normal; barriers: uncertain outcomes, treatment regrets). Although gay couples and heterosexual couples share many similar challenges, we discovered that gay men have particular sexual roles and can engage in novel accommodation practices, such as open relationships, that have not been noted in heterosexual couples. All couples, regardless of their level of sexual functioning, highlighted the need for more extensive programming related to sexual rehabilitation. Equitable rehabilitative support is critical to assist homosexual couples manage distress associated with prostatectomy-related sexual dysfunction.

[Masturbation device (EGG) as a new penile rehabilitation tool: a pilot study]

Erectile dysfunction following radical prostatectomy (RP) is still a significant burden as a post-operative morbidity, despite advances in nerve-sparing techniques and penile (erectile function) rehabilitation (PR) programs. We assessed the effects of stimulation with the masturbation device "EGG" on enhancement of erectile response along with administration of phospho diesterase type 5 inhibitor. We also studied the change of self-esteem and motivation for continuation of PR after stimulation with EGG. Eight nonresponders for PDE5-I who underwent retropubic RP were enrolled. Patients' median age was 71.5 years old. No patients received adjuvant therapy for prostate cancer. The patients' erectile response in the penile rehabilitation session (masturbation) with PDE5-I＋manual stimulation and PDE5-I＋stimulation with EGG were evaluated by erection hardness score (EHS). Changes of self-esteem and motivation for penile rehabilitation were assessed by the self-esteem subscale of the Self-Esteem and Relationship (SEAR) questionnaire and one original question, respectively. PDE5-I ＋ stimulation with EGG significantly enhanced EHS compared to PDE5-I＋manual stimulation in the eight patients (p＝0.027). Transformed score of self-esteem subscale score of SEAR questionnaire was significantly increased in the PR session with EGG compared to the PR session with manual stimulation (p＝0.043). Six patients who showed a better erectile response with EGG retained motivation for continuation of PR. PDE5-I＋stimulation with EGG improved the erectile response in post-RP patients. EGG as a masturbation device may have a potential for contribution to successful PR.

A one-day couple group intervention to enhance sexual recovery for surgically treated men with prostate cancer and their partners: a pilot study

Researchers evaluated the acceptance and effectiveness of a group intervention that provided education about post-prostatectomy sexual recovery and peer support for couples. Couples valued the intervention and retained the information. Partners became accepting of erectile dysfunction and communicated more openly about upsetting topics.

[Advances in superenzyme gene therapy in penile rehabilitation]

Erectile dysfunction (ED) is an almost unavoidable complication of radical prostatectomy. At present, though the concept of penile rehabilitation (PR) is accepted by most clinicians, the outcomes of erectile function recovery vary widely. Prostacyclin (PGI2) is a prostanoid and a main vasoprotectant which induces smooth muscle relaxation, but not used for replacement therapy because of its high unstability. SuperEnzyme is capable of continuous, specific and targeted promotion of PGI2 synthesis, and helps PR in ED patients after radical prostatectomy. SuperEnzyme gene therapy has a promising prospect for PR and the management of ED. This review updates SuperEnzyme gene therapy in PR.

[Tadalafil rehabilitation therapy for erectile dysfunction following prostatectomy]

Radical prostatectomy (RP) is preferred for many patients with clinically localized prostate cancer. Despite the introduction of the nerve sparing technique and progressive modifications on RP, postoperative preservation of penile erectile function remains a challenge to urologists. Earlier initiation of penile rehabilitation can significantly improve the patient's quality of life affected by erectile dysfunction (ED) following RP. Tadalafil, a long-acting PDE5 inhibitor with a unique clinical profile, has proved effective in penile rehabilitation in the treatment of RP-associated ED in both clinical trails and animal models. This article reviews current strategies for the management of ED after RP and evaluates the efficacy and safety of tadalafil in post-RP penile rehabilitation.

Conservative management for postprostatectomy urinary incontinence

BACKGROUND

Urinary incontinence is common after both radical prostatectomy and transurethral resection of the prostate (TURP). Conservative management includes pelvic floor muscle training with or without biofeedback, electrical stimulation, extra-corporeal magnetic innervation (ExMI), compression devices (penile clamps), lifestyle changes, or a combination of methods.

OBJECTIVES

To assess the effects of conservative management for urinary incontinence after prostatectomy.

SEARCH METHODS

We searched the Cochrane Incontinence Group Specialised Register (searched 24 August 2011), EMBASE (January 1980 to Week 48 2009), CINAHL (January 1982 to 20 November 2009), the reference lists of relevant articles, handsearched conference proceedings and contacted investigators to locate studies.

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials evaluating conservative interventions for urinary continence in men after prostatectomy.

DATA COLLECTION AND ANALYSIS

Two or more review authors assessed the methodological quality of trials and abstracted data. We tried to contact several authors of included studies to obtain extra information.

MAIN RESULTS

Thirty-seven trials met the inclusion criteria, 33 amongst men after radical prostatectomy, three trials after transurethral resection of the prostate (TURP) and one trial after either operation. The trials included 3399 men, of whom 1937 had an active conservative intervention.  There was considerable variation in the interventions, populations and outcome measures.  Data were not available for many of the pre-stated outcomes.  Men's symptoms improved over time irrespective of management. Adverse effects did not occur or were not reported.There was no evidence from eight trials that pelvic floor muscle training with or without biofeedback was better than control for men who had urinary incontinence after radical prostatectomy (e.g. 57% with urinary incontinence versus 62% in the control group, risk ratio (RR) for incontinence after 12 months 0.85, 95% confidence interval (CI) 0.60 to 1.22) as the confidence intervals were wide, reflecting uncertainty. However, one large multicentre trial of one-to-one therapy showed no difference in any urinary or quality of life outcome measures and had narrower confidence intervals. There was also no evidence of benefit for erectile dysfunction (56% with no erection in the pelvic floor muscle training group versus 55% in the control group after one year, RR 1.01, 95% CI 0.84 to 1.20). Individual small trials provided data to suggest that electrical stimulation, external magnetic innervation or combinations of treatments might be beneficial but the evidence was limited. One large trial demonstrated that there was no benefit for incontinence or erectile dysfunction from a one-to-one pelvic floor muscle training based intervention to men who were incontinent after transurethral resection of the prostate (TURP) (e.g. 65% with urinary incontinence versus 62% in the control group, RR after 12 months 1.05, 95% CI 0.91 to 1.23).In eight trials of conservative treatment of all men after radical prostatectomy aimed at both treatment and prevention, there was an overall benefit from pelvic floor muscle training versus control management in terms of reduction of UI (e.g. 10% with urinary incontinence after one year versus 32% in the control groups, RR for urinary incontinence 0.32, 95% CI 0.20 to 0.51). However, this finding was not supported by other data from pad tests. The findings should be treated with caution, as most trials were of poor to moderate quality and confidence intervals were wide. Men in one trial were more satisfied with one type of external compression device, which had the lowest urine loss, compared to two others or no treatment. The effect of other conservative interventions such as lifestyle changes remains undetermined as no trials involving these interventions were identified.

AUTHORS' CONCLUSIONS

The value of the various approaches to conservative management of postprostatectomy incontinence after radical prostatectomy remains uncertain. It seems unlikely that men benefit from one-to-one pelvic floor muscle training therapy after transurethral resection of the prostate (TURP).  Long-term incontinence may be managed by external penile clamp, but there are safety problems.

Management of post-prostatectomy erectile dysfunction

The management of post-prostatectomy erectile function has been debated since the nerve sparing radical prostatectomy was first introduced. A number of penile rehabilitation protocols have been proposed with varying degrees of success and patient satisfaction. My management of post-prostatectomy erectile dysfunction has evolved based on an honest and critical appraisal of the literature and my own experience and research. A review of major studies published on the topic of post-prostatectomy penile rehabilitation is included here, in addition to a critical evaluation of my own clinical practice. After evaluating the efficacy of these various approaches, it is clear to me that a nerve sparing procedure is only one of many factors involved in recovering erectile function. Moreover, in addition to assessing a patient's goals and their motivation for erectile function after prostatectomy, setting appropriate patient expectations is paramount to avoiding patient frustration. A frank evaluation and discussion with a patient and their partner is paramount to managing these expectations. A "one size fits all" approach is not appropriate. Herein, I discuss the evolution of my approach to managing post-prostatectomy erectile dysfunction.

[The patient after radical prostatectomy: complexity and efficiency of a urological rehabilitation program]

Timely physical and mental convalescence and an early recovery of functional side effects belong to an efficient treatment concept for prostate cancer. Every prostate cancer patient has a right to take part in a urological rehabilitation program (Germany). The objectives are continence, potency, overcoming physical complaints, reduction of health risk factors, and psychological support. The results presented show the complexity and efficiency of a urological rehabilitation program.

[Counselling for erectile dysfunction during inpatient rehabilitation after radical prostatectomy]

For men erectile function is essential for quality of life. Besides urine incontinence postsurgical erectile dysfunction (ED) following radical prostatectomy (RPE) represents a significant and prevalent problem. One of the first approaches to this condition should be a consultation performed by professionals in a rehabilitation clinic.A total of 149 patients post RPE participated in this prospective study. All patients were questioned about their understanding of postoperative surgical ED after RPE and if affected they were asked about their own psychological burden as well as their knowledge of possible therapy options. The qualities of presurgical patient information as well as the modules of information pertaining to ED during the rehabilitation were evaluated. Of the patients, 53% expressed that they experienced a considerable burden due to postsurgical ED during their follow-up rehabilitation (AR group) and 70% of the patients during oncological rehabilitation treatment (rehab group). Men who were sexually more active prior to surgery suffered more from postsurgical ED than their less active counterparts. A negative correlation between psychological burden and age was found in the AR group, which however was levelled in the rehab group. Particularly in older patients the burden of ED increases with more time elapsing after the operation. The medical information on ED therapy options provided during the inpatient rehabilitation was considered to be essential by 60% of the men in the AR group and 48% of the patients in the rehab group.Therapeutic possibilities for postsurgical ED following RPE cannot always be given to patients in the preoperative phase or during their stay in the hospital. Since however a large majority of men suffer from postoperative ED following RPE a specialized inpatient urological rehabilitation is suited for a comprehensive consultation.

Re-constructing masculinity following radical prostatectomy for prostate cancer

Prostate cancer is common in older men. Surgical treatment involving removal of the prostate can result in temporary or permanent erectile dysfunction (ED) and incontinence and have a major impact on men's masculine identity. Seven men were interviewed about their experiences and concerns following prostatectomy, and the transcripts were analysed employing Foucauldian Discourse Analysis to identify the ways in which they constructed their masculinity. Participants drew upon four main discourses when discussing the impact of surgical treatment on their sense of masculinity: masculine identity and sexual activity, ED as a normative experience, mental resilience and vulnerability. Penetrative sex was constructed as central to a masculine identity, but inability to achieve this was normalised in terms of the ageing process. Stereotypically masculine qualities of emotional control and rationality were drawn on in describing their reaction to the diagnosis and treatment of cancer but they also experienced a new-found sense of physical vulnerability. The findings are discussed in terms of their implications for the clinical management of ED post-surgery and helping men adjust to life following treatment.

Molecular mechanisms of vacuum therapy in penile rehabilitation: a novel animal study

BACKGROUND

Penile rehabilitation (PR) is widely applied after radical prostatectomy. Vacuum erectile device (VED) therapy is the one of three PR methods used in the clinical setting that improve erectile function (EF) and is the only PR method which may preserve penile length. However, its unknown mechanism hampered doctors' recommendations and patients' compliance.

OBJECTIVES

To assess the effects of VED therapy on erectile dysfunction (ED) in a rat model of bilateral cavernous nerve crush (BCNC) and to investigate the molecular mechanism of VED in postprostatectomy ED.

DESIGN, SETTING, AND PARTICIPANTS

This was an experimental study using Sprague-Dawley rats in three groups: sham, BCNC, and BCNC plus VED.

INTERVENTION

Intervention included BCNC, electrical stimulation of the cavernous nerve (CNS), and VED therapy.

MEASUREMENTS

At the end of a 4-wk period, CNS was used to assess EF by maximum intracavernosal pressure (ICP)/mean arterial pressure (MAP) ratio and duration (area under the curve [AUC]). For the structural analyses, whole rat penis was harvested. Terminal deoxynucleotidyl transferase biotin-dUTP nick end labeling assay was used for the assessment of apoptotic indices (AI). Immunohistochemistry was performed for endothelial nitric oxide synthase (eNOS), α-smooth muscle actin (ASMA), transforming growth factor beta 1 (TGF-β1), and hypoxia inducible factor-1α (HIF-1α). Staining for Masson's trichrome was utilized to calculate the smooth muscle/collagen ratios.

RESULTS AND LIMITATIONS

EF was improved with VED therapy measured by ICP/MAP ratios and AUC. VED therapy reduced HIF-1α expression and AI significantly compared with control. Animals exposed to VED therapy had decreased TGF-β1 expression, increased smooth muscle/collagen ratios, and preserved ASMA and eNOS expression.

CONCLUSIONS

To our knowledge, this is the first scientific study to suggest that VED therapy in the BCNC rat model preserves EF through antihypoxic, antiapoptotic, and antifibrotic mechanisms.

[Application of physiobalneotherapeutic factors in the combined rehabilitative treatment of patients with chronic bacterial prostatitis complicated by erectile dysfunction]

Patients with chronic bacterial prostatitis complicated by erectile dysfunction received combined rehabilitative treatment based on the use of various combinations of physiobalneotherapeutic factors, such as ultrasound, local negative pressure, white and yellow turpentine or sodium chloride baths, supplemented by basal medicamentous therapy in the form of rectal suppositories. Efficiency of therapy involving sodium chloride, white and yellow turpentine baths was estimated at 85, 60, and 75% respectively.

The role and structure of a postradical prostatectomy penile rehabilitation program

Erectile dysfunction (ED) is common after radical prostatectomy (RP). ED has a negative impact on health-related quality of life. Penile rehabilitation is defined as the use of any drug or device at or after RP to maximize erectile function recovery. The purpose of penile rehabilitation is the prevention of corpus cavernosal smooth muscle structural alterations not only to maximize the chances of a man having recovery of functional erections but also returning him to his preoperative erectile function level. Appreciating the value of penile rehabilitation requires understanding five concepts: the pathophysiology of ED after RP, cavernosal oxygenation, venous leak, and both the animal and human data supporting this strategy. This paper gives an overview of these factors and attempts to give a common-sense, practical guide to a rehabilitation program.

[Penile endoprosthesis in complex rehabilitation of wounded and ill persons with erectile dysfunction]

Morbidity of erectile dysfunction among men of every age is 10%. It's supposed that now-days in the world about 100 mln of men have organic erectile dysfunction. Specialist of the 6th MMCH of Ministry of Defense have elaborated a rehabilitation program for military service men with erectile dysfunction. This program includes a complex clinical-psychological checkup, methods of reconstruction of copulative capacity, evaluation of effectiveness of realized treatment. Evaluation of quality of result of phalloendoprosthesis has shown that 92,3% of patients estimate the result as excellent and good, 5,2%--as satisfactory, 2,5% have not sex life.

[Management of sexual dysfunctions in the rehabilitation of cardiovascular diseases. Results of a staff survey]

BACKGROUND AND PURPOSE

Many studies demonstrate a high prevalence of erectile dysfunction (ED) in cardiovascular patients. Findings show that patients often do not talk about their sexual problems. Many patients believe that their physician would not take their problem seriously. However, they wish to be asked by their physician and want to get information. The medical staff also avoids to broach the issue of sexual problems even when they assume an ED. Reasons for an insufficient inquiry are often lack of time or knowledge as well as emotional inhibitions.

METHODS

51 members of the medical staff of five hospitals for rehabilitation of cardiovascular diseases filled in a standardized, anonymous five-page questionnaire. It consisted of questions regarding sociodemography, estimated prevalence of sexual dysfunction, knowledge, responsibility, impediments for adequate diagnosis and therapy, as well as need for continuing medical education. Likely predictors (age, sex, profession, knowledge, and responsibility) for an active attitude were examined using relative risks.

RESULTS

Of the 51 employees, 54% were men, more than half were physicians. The mean age was 44.3 years. The estimated prevalence of sexual dysfunction was 45.4 +/- 20.3%. Less than half of the medical professionals rated their knowledge concerning therapy motivation (47.9%) and general consultation of cardiovascular patients (38.8%) as at least good (see Figure 1). While more than two thirds felt responsible for motivation to subsequent treatment of sexual dysfunction, less than one quarter motivated the patients actively. Over 50% felt responsible for consultation and information, but only 27% did it actively (see Figure 2). The main impediment for an adequate management of sexual problems was the lack of time (38.3%). However, every fourth also believed that the patient would not accept the diagnosis (29.2%) or a therapy (22.9%). One third of the employees agreed that the own lack of knowledge makes care of sexual problems difficult. On the question what would be helpful to improve the management with sexual concerns, most employees said that education and training (85.7%) would be the most effective method (see Figure 3). The highest need for training can be seen in diagnostics (64.4%; see Figure 4). Almost all professionals believed that a screener would be reasonable. A higher knowledge state was the only significant predictor for an active management of sexual problems (see Table 1).

CONCLUSION

The reported prevalence of sexual dysfunction in cardiac rehabilitation is very high. This requires skills concerning diagnosis and treatment of sexual dysfunction, which are only scarcely present. Furthermore, there are many impediments that are mainly positioned in the health-care system. The skills should be improved by an effort in continuing medical education. Patients with ED often have depression and a reduced quality of life. To improve the quality of life of patients in the cardiovascular rehabilitation, the treatment of ED is a necessary condition. Trials show that a widespread rehabilitation program which includes a sexual education leads to a better sexual activity. The patients' quality of life can only be improved, if the medical staff includes relevant concomitant disorders to cardiovascular disease, like ED, in the treatment program of patients.

Early penile rehabilitation following radical prostatectomy: Cleveland clinic experience

Erectile dysfunction is one of the most important quality of life issues following radical prostatectomy. The potency rates reported following nerve-sparing technique varies between 40 and 86%, and the time period required for complete recovery of erectile function varies from 6 to 24 months. The literature evidence suggests that lack of natural erections during this period of time produces cavernosal hypoxia. Prolonged periods of cavernosal hypoxia induce fibrosis, which later increases the incidence of venous leak. Recently, there is a growing interest among the physicians to interrupt these events by preventing cavernosal hypoxia during the period of neuropraxia. Initial studies using intracavernosal injection appears to be beneficial. In this article, we reviewed the pathophysiology of cavernosal hypoxia following radical prostatectomy with currently available evidence for the interventions to promote the nerve recovery and regeneration.

Controversies in Sexual Medicine: Penile Rehabilitation Should Become the Norm for Radical Prostatectomy Patients

INTRODUCTION

The Journal of Sexual Medicine (JSM) held a debate at the annual fall meeting of the Sexual Medicine Society of North America (SMSNA). The motion was "Penile Rehabilitation Should Become the Norm for Radical Prostatectomy Patients." At the suggestion of several SMSNA members, it was requested that this debate might be of interest to JSM readers in the form of a published controversy.

METHODS

Two debate speakers with expertise and/or strong opinions in the area of penile rehabilitation submitted their literature-review, evidence-based opinions on the topic.

MAIN OUTCOME MEASURE

Literature review of laboratory basic science and clinical research studies on penile rehabilitation.

RESULTS

Penile rehabilitation involves prophylactic procedures designed to improve oxygen delivery to penile erectile tissues, aimed at preserving erectile tissue health and minimizing erectile tissue damage that otherwise occurs during the period of neural recovery to the autonomic cavernosal nerve following radical prostatectomy. There are several studies in the sexual medicine literature on penile rehabilitation after radical prostatectomy, and the positive results appear to support this concept, the rationale, and mechanism. The use of prophylactic penile rehabilitation programs has not been fully elucidated, nor have the results been replicated in large multicenter placebo-controlled trials.

CONCLUSION

Penile rehabilitation may be performed along with counseling with the couple, vacuum erection therapy, and vacuum erection device therapy if it is the patient and partner's preference, provided that it is undertaken in a safe and effective manner and is monitored closely.

Penile rehabilitation after radical prostatectomy: where do we stand and where are we going?

INTRODUCTION

Postprostatectomy erectile dysfunction (ED) remains a serious quality-of-life issue. Recent advances in the understanding of the mechanism of postprostatectomy ED have stimulated great attention toward penile rehabilitation.

AIM

This review presents and analyzes a contemporary series of the recent medical literature pertaining to penile rehabilitation therapy after radical prostatectomy (RP).

MAIN OUTCOME MEASURES

The laboratory and clinical studies related to penile rehabilitation are analyzed. The validity of the methodology and the conclusion of the findings from each study are determined.

METHODS

The published and presented reports dealing with penile rehabilitation following RP in human and cavernous nerve injury in animal models are reviewed.

RESULTS

Exciting scientific discoveries have improved our understanding of postprostatectomy ED at the molecular level. The rationale for postprostatectomy penile rehabilitation appears to be logical according to animal studies. However, clinical studies have not consistently replicated the beneficial effects found in the laboratory studies. Currently available clinical studies are flawed due to short-term follow-up, small number of patients in the studies, studies with retrospective nature, or prospective studies without control. Rehabilitation programs are also facing a challenge with the compliance, which is critical for success for any rehabilitation program. At the present time, we do not have concrete evidence to recommend what, when, how long, and how often a particular penile rehabilitative therapy can be used effectively.

CONCLUSIONS

Large prospective, multicentered, placebo-controlled trials with adequate follow-up are necessary to determine the cost-effective and therapeutic benefits of particular penile rehabilitative therapy or therapies in patients following the treatment of clinically localized prostate cancer. Until such evidence is available, it is difficult to recommend any particular penile rehabilitation program as a standard of practice.

Cryoablation as Primary Treatment for Localized Prostate Cancer Followed by Penile Rehabilitation

OBJECTIVES

To determine the medium term efficacy and morbidity of patients who underwent cryoablation as primary therapy for localized prostate cancer followed by a penile rehabilitation regimen.

METHODS

Patients were treated with whole gland cryoablation. Those potent at intervention were encouraged to use a vacuum erection device regularly after treatment. Incontinence was defined as any leakage of urine. Potency was defined as the ability to achieve an erection sufficient to complete intercourse with or without oral pharmaceutical agents. Biochemical failure was defined as three successive rises in prostate-specific antigen, with a final value greater than 1.0 ng/mL.

RESULTS

A total of 416 consecutive patients were treated. The mean patient age was 69.4 years, mean prostate-specific antigen level was 8.7 ng/mL, median Gleason score was 6, and median stage was T1c. The mean follow-up of the entire population was 20.4 +/- 14.7 months. Of those continent before treatment, 4.0% were incontinent at 6 months but only 2 (0.6%) used any absorbent pads. Kaplan-Meier analysis demonstrated progressive recovery of sexual function of preoperatively potent men, with 41.4% +/- 4.3% and 51.3% +/- 5.9% potent 1 and 4 years after treatment, respectively. No patients had rectal fistula. The actuarial probability of remaining biochemically disease free at 4 years was 79.6% +/- 2.4%, with a mean time to failure of 4.2 months. After therapy, 168 patients underwent biopsy; 17 had positive findings (10.1%). The positive biopsy rate for the entire population was 4.1% (17 of 416).

CONCLUSIONS

The results of our study have indicated that cryoablation as a primary treatment of localized prostate cancer is effective with acceptable morbidity. The use of a penile rehabilitation regimen after treatment appeared to substantially increase postcryoablation potency.

[Postoperative problems and after-care in post-radical-prostatectomy patients]

Essential components of tumor follow-up in prostate cancer patients are considered to be the determination of PSA in combination with digital rectal examination, and abdominal together with transurethral ultrasonography. Depending upon the symptoms presenting, additional specialist urological examinations, such as urine flow measurement and cystoscopy may be indicated. The follow-up should be carried out every three months in the first postoperative year, every 6 months in the following years, and annually thereafter.

[Whole rehabilitation: a new goal of erectile dysfunction therapy]

Phosphodiesterase type 5 (PDE5) inhibitors effectively enhance the erectile function of the patients with erectile dysfunction (ED). The use of sildenafil citrate is expanding to a broader extent. Pulmonary artery hypertension has become a new indication of sildenafil. Sildenafil could improve the epithelial function in several vascular conditions in clinical trials. This article reviews the recent advances on basic and clinical studies of ED and sildenafil. On animal models, sildenafil could resume the cavernous epithelial function, up-regulate the protein expression of phosphorylated endothelial NO synthase (eNOS), reverse the decreased intracavernosal pressure (ICP) induced by pudendal artery blood flow restriction or hypoxia. In clinical studies, over 50% of ED patients receiving sildenafil got a fully rigid erection (grade 4 erection). And the same percentage of post-nerve-sparing radical prostatectomy patients receiving sildenafil obtained penile rehabilitation and spontaneously resumed erection sufficient for sexual intercourse. Sildenafil treatment has contributed to the normalization of self-esteem, confidence and sexual harmony in men with ED. All this suggests that a whole rehabilitation from erectile to psychosocial function may become a new goal of ED therapy.

Update on erectile dysfunction in prostate cancer patients

PURPOSE OF REVIEW

Evolution in the management of prostate cancer includes increased attention being paid to patient quality of life after treatment, specifically with issues related to sexual function. Erectile dysfunction is one of the major concerns of patients undergoing treatment for prostate cancer. There are several recognized factors that determine the postoperative incidence of erectile difficulties, including patient age, degree of cavernosal nerve sparing during surgery, cancer stage, and associated vascular comorbidities. Early initiation of rehabilitation protocols after radical prostatectomy has been advocated to promote the speed and degree of recovery of erectile function. The aim of this communication is to review recent initiatives in erectile dysfunction restoration after prostate cancer therapy.

RECENT FINDINGS

In recognition of the neurogenic basis of erectile dysfunction after radical prostatectomy, new strategies have been devised to initiate the rehabilitation process. Type 5 phosphodiesterase inhibitors, vacuum erection devices, and intracavernosal and intraurethral application of vasoactive agents have all been reported in a positive light in recent studies. Developments in cavernous nerve graft interposition procedures, perioperative neuroprotection measures, and postoperative neurotrophic treatments aim to preserve prostate cancer patients' qualities of life.

SUMMARY

Data generated from a number of clinical investigations document that pharmacologic rehabilitation programs provide a higher rate of recovery of erectile function following radical prostatectomy. Both intracavernosal and intraurethral applications of vasoactive agents and vacuum devices can speed the recovery period for return of erectile function. Various neuroprotective and neurotrophic approaches are thought to provide integral roles for the maintenance of sexual function in men undergoing prostate cancer therapy.

ORIGINAL RESEARCH—PSYCHOLOGY: Sexual Counseling Improved Erectile Rehabilitation After Non‐Nerve‐Sparing Radical Retropubic Prostatectomy or Cystectomy—Results of a Randomized Prospective Study

AIM

The efficacy of prostaglandin E1 (PGE1)-intracavernous injection (ICI) therapy for erectile dysfunction (ED) after non-nerve-sparing (NNS) radical pelvic surgery depends on patient compliance. The purpose of this study was to verify the utility of sexual counseling in ICI in terms of treatment efficacy, compliance, and dropout rate.

METHODS

In this prospective randomized study, 57 patients with ED after NNS radical prostatectomy or cystectomy were divided: 29 patients (group SC+) were treated with sexual counseling and PGE1-ICI therapy; the others 28 (group SC-) were treated with only ICI. At the start of the study all patients were administered the International Index of Erectile Function (IIEF) questionnaire and ICI training test; follow-up (at 3, 6, 9, 12, 18 months) was achieved by home Sildenafil test and ambulatory IIEF test; sexual counseling was provided only to group SC+.

RESULTS

The mean IIEF score at the end of study was 26.5 (SC+) vs. 24.3 (SC-) (P < 0.05); eight patients (SC+, 27.5%) became responders to home Sildenafil vs. five (SC-, 17.8%) (P < 0.05); no dropout cases occurred (SC+) vs. eight (SC-, 28.5%) (P < 0.05). Moreover, we recorded best IIEF scores in group SC+ in sexual satisfaction (P < 0.05), sexual desire (P < 0.05), orgasmic function, and general satisfaction. Mean PGE1 doses were better in group SC+ (P < 0.05). ICI-oriented sexual counseling was utilized to motivate couples, to improve sexual intercourses, to correct mistakes in ICI administration. At the end of follow-up 21 patients (SC+) declared themselves satisfied vs. 12 (SC-).

CONCLUSIONS

ICI-oriented sexual counseling in ICI increased the efficacy of treatment, the compliance, and Sildenafil responders rate, decreased the dropout rate.

Versorgung der erektilen Dysfunktion nach radikaler Prostatektomie in Deutschland

INTRODUCTION

The aim of this national study was to evaluate ED management after RPX (without any postoperative adjuvant therapy or tumor relapse) from the patient's view compared to the urologist's view.

MATERIAL AND METHODS

In May 2003 we queried 1063 urologists and 801 patients following radical prostatectomy without adjuvant therapy. They were asked about preserved potency without erectile aid, existing wish for ED therapy, recommended or tested erectile aid (oral, transurethral, intracorporal, vacuum constriction device[VCD], penile implant) as well as the long-term use. Return rate: patients 80.1%, urologists 26.7%.

RESULTS

According to the urologists' view 9.1% of their affected patients were potent postoperatively without a device, but according to the polled patients only 4.7%. The wish to be treated for erectile dysfunction existed in the urologists' opinion in 46.1% of their patients, while they considered that 44.8% had no wish for treatment. On the other hand, 59.3% of the patients would like to be treated and only 28.5% did not want any kind of treatment. Regarding the long-term use of therapy for ED, the urologists thought that 26.1% of their patients did not receive therapy for the problem, and 69.7% of the patients stated they received no long-term therapy. Only 30.3% of the patients confirmed long-term therapy, while the urologists thought that 73.9% of the patients used an erectile aid. Definite therapy in the urologists' opinion involved: oral medication in 38.4%, MUSE in 3.6%, (SKAT) in 37.3%, VCD in 20.4%, and a prosthesis in 0.3%. Indeed 19.8% of the patients used oral medication, 1.7% MUSE, 26.7% SKAT, 50.9% VCD, and 0.9% penile implant. Considering the satisfaction of patients, urologists thought that 46.2% of the patients were satisfied with their treatment of ED, but only 28.9% of the patients were actually satisfied themselves.

CONCLUSIONS

The comparison of patients' and urologists' views shows a clearly different description of the ED situation after RPX. The proportion of patients with a wish for treatment and the proportion of dissatisfied patients are much higher from the patients' view. This demonstrates an undertreatment of ED patients after RPX, which should also be taken into account under the current changes in the German health care system.
