Efficacy of a new vacuum erection device (Vigor 2020) for erectile dysfunction: A retrospective study in Japan.

OBJECTIVES: The vacuum erection device (VED) is a second-line treatment tool recommended in erectile dysfunction (ED) guidelines but has long been unavailable in Japan. A new VED, Vigor 2020® (A & HB Company Limited, Tokyo, Japan), has now been manufactured and received medical approval from the Pharmaceuticals and Medical Devices Agency in Japan. We conducted a retrospective observational study of ED patients who used Vigor 2020 in clinical practice. METHODS: We analyzed male ED patients aged ≥20 years treated with Vigor 2020 in our outpatient clinics. The primary endpoint was improvement of erection as evaluated by an Erection Hardness Score (EHS) of ≥1 point. Secondary endpoints were improvement of sexual function and adverse events as evaluated by the International Index of Erectile Function (IIEF) and Male Sexual Health Questionnaire for assessing ejaculatory dysfunction (MSHQ-EjD). RESULTS: Thirty-three patients (mean age, 57.21 [27-86] years) could be evaluated before and after using Vigor 2020. Among the 16 patients with baseline EHS ≤2, 14 (93.33%) improved by ≥1 point, and 10 of these 16 patients (62.50%) improved to EHS ≥3 and could insert vaginally. Significant improvement was observed for IIEF total score and for the MSHQ-EjD in patients with an EHS of ≥3 after use of Vigor 2020. No patient experienced significant adverse events. CONCLUSIONS: The Vigor 2020 may be an efficacious treatment tool for ED. Patients with significant ED experienced not only significant improvement of erection but also improvement of ejaculation with its use.

Vacuum Erection Device Plus Once-Daily Tadalafil Improve Clinical Outcomes after Extracorporeal Shock Wave Therapy in Men Affected by Erectile Dysfunction Associated with Peyronie's Disease.

BACKGROUND: The purpose of this study is to examine the combination of the mechanical effects of penile therapy with vacuum erection devices (VEDs) plus PDE5i, which improve clinical outcomes after extracorporeal shockwave therapy (ESWT) in men affected by erectile dysfunction (ED) associated with Peyronie's disease (PD). METHODS: A total of 153 medical records of patients affected by PD in stable stage with ED and treated with ESWT were divided into two groups. Group A (GA) included 72 men treated with ESWT, mechanical stretching with VEDs and PDE5ì (Tadalafil 5 mg), and Group B (GB) included 81 men who received only ESWT plus Tadalafil 5 mg with the same protocol of GA. The patients in both groups were assessed at baseline and follow-up for erectile function, painful erections, penile plaque size, and penile curvature. The results were evaluated at baseline and 3, 6, and 12 months after the treatments. RESULTS: Three months after the treatment, GA patients had a reduction in penile curvature degree from a mean ± SD of 33.91 ± 8.34° at baseline to a mean ± SD of 19.46 ± 7.15° after 12 months, whereas pain in an erection or during intercourse was resolved completely in 88.9% of the patients. The mean ± SD IIEF-15 score of patients affected by severe/moderate ED further improved significantly in the GA group (p < 0.001) after 3, 6, and 12 months of treatment. There were no permanent adverse sequelae after treatments. CONCLUSIONS: The regular use of a VED plus Tadalafil in patients who had undergone ESWT significantly provided more benefit in patients with PD in terms of penile deformity, pain, and erectile function.

Multimodal treatments based on Tadalafil during acute phase of Peyronie's disease: experience at two referral academic centers.

AIM: The purpose of this study is to identify the clinical outcomes of patients during acute phase of Peyronie's disease (PD) treated with daily Tadalafil 5 mg associated with non-surgical treatments such as intra-plaque verapamil injections (IVI), vacuum erection devices (VED) or extra corporeal shockwave therapy (ESWT). METHODS: 445 patients with PD in acute stage were treated as it follows: Group 1(G1) 117 men with only Tadalafil 5 mg once a day for 3 months; Group 2(G2) 106 men with IVI plus Tadalafil 5 mg for a period of 12 weeks; Group 3(G3) 124 men that received ESWT for 6 weeks plus Tadalafil with the same protocol of G1; Group 4(G4) 98 men with VED plus Tadalafil 5 mg for 3 months. There were assessed at baseline and follow-up: Erectile dysfunction (ED), presence and severity of painful erections, penile plaque size and penile curvature degree. The results were evaluated at baseline and 3,6,12 months. RESULTS: Not statistically significant differences emerged between the two groups at baseline, except for higher presence of patients with ED in in G3(7.4%) vs other groups(p < 0.001). Three months after the treatment in G3 men had a significant reduction of penile curvature degrees after 1 year by treatments, whereas pain in an erection or during intercourse was resolved completely in 75% of the patients. CONCLUSIONS: Our study highlights that multimodal therapy has beneficial long-term effects not only in the decrease of ED symptoms, but also in the relief of the penile curvature and the quality of life.

Erectile Dysfunction: Treatments, Advances and New Therapeutic Strategies.

Erectile dysfunction (ED) is the inability to get and maintain an adequate penile erection for satisfactory sexual intercourse. Due to its negative impacts on men's life quality and increase during aging (40% of men between 40 and 70 years), ED has always attracted researchers of different disciplines, from urology, andrology and neuropharmacology to regenerative medicine, and vascular and prosthesis implant surgery. Locally and/or centrally acting drugs are used to treat ED, e.g., phosphodiesterase 5 inhibitors (first in the list) given orally, and phentolamine, prostaglandin E1 and papaverine injected intracavernously. Preclinical data also show that dopamine D4 receptor agonists, oxytocin and α-MSH analogues may have a role in ED treatment. However, since pro-erectile drugs are given on demand and are not always efficacious, new strategies are being tested for long lasting cures of ED. These include regenerative therapies, e.g., stem cells, plasma-enriched platelets and extracorporeal shock wave treatments to cure damaged erectile tissues. Although fascinating, these therapies are laborious, expensive and not easily reproducible. This leaves old vacuum erection devices and penile prostheses as the only way to get an artificial erection and sexual intercourse with intractable ED, with penile prosthesis used only by accurately selected patients.

Management of male erectile dysfunction: From the past to the future.

Erectile dysfunction is a common disease of the male reproductive system, which seriously affects the life quality of patients and their partners. At present, erectile dysfunction is considered as a social-psychological-physiological disease with complex etiology and various treatment methods. Oral PDE5I is the first-line treatment for erectile dysfunction with the advantages of high safety, good effect and non-invasiveness. But intracavernosal injection, hormonal replacement therapy, vacuum erection device, penile prosthesis implantation can also be alternative treatments for patients have organic erectile dysfunction or tolerance to PDE5I. With the rapid development of technologies, some new methods, such as low-intensity extracorporeal shock wave and stem cell injection therapy can even repair the organic damage of the corpora cavernosa. These are important directions for the treatment of male erectile dysfunction in the future. In this mini-review, we will introduce these therapies in detail.

Emerging Roles of Penile Traction Therapy and Vacuum Erectile Devices.

INTRODUCTION: Penile traction therapy (PTT) and vacuum erection devices (VED) are nonsurgical conservative treatment options that have been used in the treatment of various urologic and sexual disorders such as Peyronie's Disease (PD) and Erectile Dysfunction (ED). Recently expanded uses for these therapies now include penile lengthening and with surgical interventions such as penile prosthesis surgery (PPS) and radical prostatectomy (RP). These devices can be used as both monotherapy or combination therapy. OBJECTIVES: To review the indications and clinical studies for PTT and VED. METHODS: A literature search was conducted using PubMed to identify relevant studies addressing PTT, VED, and their indications. Searched terms included penile traction therapy, penile traction device, vacuum erection device, Peyronie's disease, penile prosthesis, radical prostatectomy, subjectively small penis, penile lengthening, erectile dysfunction. RESULTS: PTT with dynamic traction devices has shown favorable benefits for PD in many studies. The benefits of VED for PD cannot be confirmed due to limited studies with poor quality. In posterior urethroplasty, VED shows promise postoperatively, with additional trials also needed. In PPS, both PTT and VED have had positive findings in pre- and postoperative treatment. In RP patients, VED use has had positive outcomes while new literature shows beneficial effects of dynamic PTT and provides a basis for future studies. VED use does not show great benefit in patients with small penis, however PTT does have some positive findings. In ED, VED has a history of successful use and PTT has promising new data available. CONCLUSION: PTT and VED have been utilized in urologic and sexual conditions with various success. Several promising areas utilizing both PTT and VED are being studied, however, more research needs to be done in these areas prior to becoming a standard treatment.

Hard Times: Prostate Cancer Patients' Experiences with Erectile Aids.

BACKGROUND: Prostate cancer (PCa) treatments commonly lead to erectile difficulties. While the mainstay treatment is erectile aids (EAs) to promote erectile recovery, some men never use these treatments and those whose do use EAs often abandon them in the long-term. AIM: The goal of this study was to examine PCa patients' experiences with EAs, to elucidate relationships between experiences with EAs on psychological and sexual well-being, and to explore benefits and drawbacks to EA use. METHODS: A self-report survey including validated questionnaires was administered to examine PCa patients' use and perceptions of helpfulness of EAs, and to characterize associations between use, perceived helpfulness, and psychological and sexual well-being. The survey was followed by an open-ended prompt to explore participants' experiences with EAs. OUTCOMES: We surveyed 260 North American men, up to 25 years after receiving treatment for PCa. Three groups of patients were observed, including those who used EAs and perceived them to be helpful, those who used EAs and perceived them to be unhelpful, as well as a smaller group of patients who never used EAs. RESULTS: Around 80% of the sample were using or had used EAs. Despite the high frequency of use, not all men found EAs helpful. Men who used EAs and found them unhelpful reported poorer psychological and sexual well-being compared to men who didn't use aids or who used EAs but found them helpful. Results indicated both benefits and drawbacks to the use of EAs. Benefits related largely to the efficacy of the aid in promoting erections. A wide range of drawbacks were also reported. CLINICAL IMPLICATIONS: Given the negative sexual and psychological impacts associated with using EAs and finding them unhelpful, we suggest that researchers and health care providers should take care to proactively address potential challenges that are common with EA use, and also to consider the risks of failed attempts with EAs. STRENGTHS & LIMITATIONS: By using both scaled and open-ended questions, a more nuanced picture of the relative benefits and limitations of EA use within the PCa population is presented. As responses were not mandatory, a subset of participants provided comments about the use of EAs. Additionally, the sample was quite homogenous, with mostly white, American and well-educated participants, so it therefore lacks generalizability to other populations. CONCLUSION: This paper illustrates several challenges to EA use, while providing insight into reasons for abandonment of use of EAs. Walker LM, Sears CS, Santos-Iglesias P, et al.

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.

Prostatic irradiation-induced sexual dysfunction: A review and multidisciplinary guide to management in the radical radiotherapy era (Part II on Urological Management).

Prostate cancer is the most common malignancy in men and the second leading cause of cancer-related death in men. Radiotherapy is a curative option that is administered via external beam radiation, brachytherapy, or in combination. Sexual dysfunction is a common toxicity following radiotherapy, similar to men undergoing radical prostatectomy, but the etiology is different. The pathophysiology of radiation-induced sexual dysfunction is multi-factorial, and the toxicity is a major cause of impaired quality of life among long-term prostate cancer survivors. Management of a patient's sexual function during and after radiotherapy requires multidisciplinary coordination of care between radiation oncology, urology, psychiatry, pharmacy, and dermatology. This review provides a framework for clinicians to better understand prostatic radiotherapy-induced sexual dysfunction diagnosis, evaluation, and a patient-centered approach to toxicity preventive strategies and management.

Penile Stretching as a Treatment for Peyronie's Disease: A Review.

INTRODUCTION: Peyronie's disease (PD) is a debilitating condition that affects a sizable number of men worldwide. Current treatment options consist of oral therapy, intralesional injections, and surgery. Penile stretching has been used as a treatment for PD, including penile traction therapy (PTT) and vacuum erection devices (VEDs), with numerous trials completed or underway. AIM: To present and summarize the current literature on penile stretching for the treatment of PD. METHODS: Using PubMed, we performed a literature review of studies from January 1990 through July 2018 that focused on penile stretching for PD management. PTT and VED were included in the search criteria. MAIN OUTCOME METHODS: Penile curvature correction was effective, and stretched penile length was improved. RESULTS: PD therapies that use penile stretching as a mechanical intervention to alter tissue characteristics were studied. PTT has been successful in primary penile lengthening and curvature correction in the acute phase of PD. PTT also improved length retention in men undergoing plication and incision/grafting procedures. Combination of PTT and intralesional injection therapy for PD treatment requires further investigation. There are fewer studies investigating VEDs and their role in PD management, but initial small trials suggest a role in curvature correction and penile lengthening. CONCLUSIONS: Penile stretching is an effective therapy for PD. Data from limited trials suggest a role for PTT and VEDs in the management of PD, although further research is needed.

Devices for penile traction: the long and winding road to treating Peyronie's disease.

INTRODUCTION: Penile traction therapy (PTT) is increasingly being recognized as a viable nonsurgical approach to Peyronie's disease (PD). The goal of this article is to review the current literature on PTT with attention to traction protocols, devices, and outcomes. AREAS COVERED: Literature on the pathophysiology of PD, PTT as primary and adjunctive treatment for PD, perioperative use of PTT, and vacuum erection devices are all reviewed. Pertinent literature was obtained from the PubMed database. The key words 'penile traction,' 'mechanotransduction,' and 'Peyronie's disease' were searched and results were narrowed down based on relevance to the review. EXPERT COMMENTARY: PTT appears beneficial but the true magnitude of effect is difficult to discern. Most studies are not randomized, have small sample sizes, lack control arms, or have varying traction protocols. Patient compliance is critical and new devices and traction protocols are needed to maximize the benefit of PTT.

Penile Rehabilitation: The "Up"-date.

PURPOSE OF REVIEW: The purpose of this review is to review the penile rehabilitation literature published since the beginning of 2017. Specific emphasis was placed on determining how the new findings increase our understanding of the mechanisms leading to recovery of erectile function after pelvic surgery and to identify potential focus areas for future studies. RECENT FINDINGS: A meta-analysis of penile rehabilitation after prostatectomy was published in early 2017 reporting that PDE-5 inhibitors, intracavernosal injection (ICI) therapy and vacuum erection devices (VED) improved erectile function; however, the benefit was not observed after a washout period. Preclinical studies have identified potential regenerative therapies after cavernous nerve injury. SUMMARY: While significant methodological challenges remain, recent literature suggests benefits to starting penile rehabilitation immediately after surgery, but not extending past 1 year post-operatively. The cost-benefit ratio of penile rehabilitation remains unclear; however, decreasing costs of PDE-5 inhibitors as well as improvements in characterizing post-surgical erectile dysfunction may help to personalize penile rehabilitation, improve outcomes and improve the cost-benefit ratio. Better and more consistent trial design is needed to develop the optimal regimen(s) for restoring sexual function in men. Finally, future studies to translate promising preclinical regeneration therapies to humans are also needed.

Vacuum erection device in treatment of organic erectile dysfunction and penile vascular differences between patients with DM type I and DM type II.

The aim of this study is to investigate changes in the vascular system and hemodynamics between patients with organic erectile dysfunction (ED) (DM type I and II), as well as to compare the quality of sexual life between those two groups after the treatment with vacuum erection device (VED). Study enrolled 50 males with DM, aged from 35 to 67 years, who have attended the urologic clinic due to inability to attain and maintain an erection of the penis sufficient to permit satisfactory sexual intercourse. Patients were using VED and six months later were assessed for therapy results. The International Index of Erectile Function (IIEF) was used to quantify erectile dysfunction. Alprostadil injection test was also used, with Doppler color flow imaging system, to evaluate the peak systolic velocity (PSV) and diameter of cavernosal artery (DCA). Significantly higher values of PSV were obtained in patients with DM type II. Also, DCA showed significant difference between two groups of patients. There was significant improvement in three items of IIEF after six months of treatment among both groups of examinees. Patients with DM type I had more serious risk for development of arteriogenic ED. VED could be a good alternative therapy for patients who denied peroral therapy.

Is the daily use of vacuum erection device for a month before penile prosthesis implantation beneficial? a randomized controlled trial.

Patient concerns about penile length after penile prosthesis (PP) implantation for erectile dysfunction (ED) have significant impact on patients and their partners. In addition, corporal fibrosis is associated with difficult PP implantation. The preoperative use of vacuum erectile devices (VED) is an uncommon physical treatment for such concerns. Therefore, the current randomized controlled study assessed two outcomes: whether pre-operative VED use for a month before surgery would significantly increase flaccid stretched penile length (SPL) on the day of surgery, and facilitate easier corporal dilatation intraoperatively. Fifty-one patients scheduled for PP implantation for ED were randomized to either intervention group (pre-operative VED use; 10-15 min/day for ≥30 days; Group A; n = 25), or control group (no intervention; Group B; n = 26). A research assistant (blinded to the treatment assignments) recorded SPL at baseline (initial consultation) and on day of surgery. The surgeons performing the PP implantation (also blinded to the treatment assignments) provided subjective assessments of the ease of corporal dilatation. Baseline patient characteristics, demographics, and comorbidities were the same in both groups. Baseline measurements (SPL-1) were 10.71 ± 1.28 and 10.87 ± 1.26 cm in Group A and Group B, respectively; and the day of surgery measurements (SPL-2) were 11.50 ± 1.33 and 11.06 ± 1.34 cm in Group A and Group B, respectively. In terms of outcomes: mean SPL increase in Group A was significantly more by a mean of 0.80 ± 0.38 cm (p < 0.05) compared to Group B; and surgeons' subjective report of surgical ease indicated smoother corporal dilatation for Group A compared to Group B. VED use (10-15 min/day during the month prior to PP implantation) was associated with significantly increased SPL on day of surgery, and facilitated easier corporal dilatation intraoperatively. Future studies should examine the long-term outcomes of penile prosthesis implantation after pre-operative use of vacuum erectile devices.

Post-prostatectomy erectile dysfunction: contemporary approaches from a US perspective.

Success of cancer surgery often leads to life-changing side effects, and surgical treatment for malignant urologic disease often results in erectile dysfunction (ED). Patients that undergo surgical prostatectomy or cystoprostatectomy will often experience impairment of erections due to disruption of blood and nerve supply. Surgical technique, nerve sparing status, patient age, comorbid conditions, and pretreatment potency status all have an effect on post-surgical ED. Regardless of surgical technique, prostatectomy results in disruption of normal anatomy and nerve supply to the penis, which governs the functional aspects of erection. A variety of different treatment options are available for men who develop ED after prostatectomy, including vacuum erection device, oral phosphodiesterase 5 inhibitors (PDE5I), intracorporal injections, and penile prosthesis. The vacuum erection device creates an artificial erection by forming a vacuum via suction of air to draw blood into the penis. The majority of men using the vacuum erection device daily after prostatectomy, regardless of nerve-sparing status, have erections sufficient for intercourse. Phosphodiesterase 5 inhibitors remain a common treatment option for post-surgical ED and are the mainstay of therapy. They work through cyclic adenosine monophosphate and cyclic guanine monophosphate pathways and are recommended in all forms of ED. Intracorporal injections or intraurethral use of vasoactive substances may be a good second-line therapy in men who do not experience improvement with oral medications. Surgical placement of a penile prosthesis is typically the treatment strategy of choice after other options have failed. Semi-rigid and inflatable devices are available with high satisfaction rates. With careful patient counseling and proper treatment selection, patient satisfaction and improved erectile function can be achieved. We advise that patients use a vacuum erection device daily in the early postoperative period in combination with an oral PDE5I. For patients who do not respond to a vacuum erection device or PDE5I, consideration should be given to intraurethral alprostadil, intracorporal injections, or a penile prosthesis.

A pilot study to determine penile oxygen saturation before and after vacuum therapy in patients with erectile dysfunction after radical prostatectomy.

INTRODUCTION: Provoked and spontaneous nocturnal erections are thought to play a role in maintenance of male sexual health through oxygenation of the corpus cavernosa. Conversely, hypoxia is thought to be an etiological factor in the pathogenesis of cavernosal fibrosis and long-term erectile dysfunction. It has been hypothesized that the early penile hypoxia after radical prostatectomy (RP) may lead to fibrosis and consequently a decrease in stretched penile length and long-term erectile dysfunction. AIM: The aim of this study was to assess the changes in penile tissue oxygenation with vacuum erection device (VED) use. METHODS: Twenty men between 2 and 24 months following RP were enrolled prospectively. Each man cycled a VED to achieve full erection 10 consecutive times over a period of approximately 2 minutes without constriction ring. MAIN OUTCOME MEASURES: Tissue oximetry was measured at baseline and immediately after VED using a tissue oximeter at five sites: right thigh, right corpora, glans, left corpora, and left thigh. Additional measurements were captured over the course of an hour. RESULTS: Mean age and time from surgery was 58.2 years and 12.6 months, respectively, and the average Sexual Health Inventory for Men score was 7. Use of the VED significantly increased both glanular and corporal oximetry relative to the baseline values for the entire 60 minutes. An initial increase of 55% was seen in corporal oxygenation with VED use. CONCLUSIONS: This is the first study demonstrating that a single, brief application of the VED without a constriction ring results in significant improvement in penile oxygen saturation. The use of a VED has significant benefits for patients both with regard to cost and invasiveness when compared with other penile rehabilitation protocols.

The use of vacuum erection devices in erectile dysfunction after radical prostatectomy.

The risk of postoperative erectile dysfunction (ED) following radical prostatectomy (RP) is reported to be between 14% and 89%. With an increase in the detection of prostate cancer in younger men, there is a greater emphasis on the appropriate management of ED following RP. A number of options are available to manage ED after RP, including phosphodiesterase-5 inhibitors, intracorporeal injections, intraurethral alprostadil, and vacuum erection devices (VEDs). Penile rehabilitation programs are increasingly used to facilitate the return of natural postoperative erections; the VED is an ideal therapy given that it increases blood flow and oxygenation to the corpora to reverse the changes that result in ED after RP.

Current penile-rehabilitation strategies: Clinical evidence.

We review the current strategies used for penile rehabilitation (PR) after a radical prostatectomy, where PR is defined as the attempt to restore spontaneous erectile function so that the patient can generate erections with no need for erectile aids. We searched PubMed for relevant reports, using the keywords 'radical prostatectomy', 'penile rehabilitation', 'phosphodiesterase inhibitors', 'vacuum erection device', 'injection therapy', 'urethral suppository', and 'erectile dysfunction'. In all, 155 articles were identified and reviewed, and had a level of evidence ranging from 1b-4. The use of PR strategies should be based on the patient's goals after a thorough explanation of realistic expectations, and the risks and consequences of the various treatment options. While a multitude of studies suggest a benefit with PR strategies, there are no established, proven regimens. Further research is needed to establish the optimal approaches to PR.

Penile rehabilitation after radical prostatectomy: patients' attitude and feasibility in China.

OBJECTIVE: To investigate the behavior of Chinese erectile dysfunction (ED) patients after radical prostatectomy (RP) who were offered the penile rehabilitation and to assess their attitude and feasibility of rehabilitation after RP in China. MATERIALS AND METHODS: Comprehensive medical and sexual histories of 187 evaluable PCa patients for RP were obtained together with their attitude towards penile rehabilitation. The rehabilitation data was compared between patients who accepted this treatment or not. The successful intercourse rate six months after treatment was also compared among three rehabilitation interventions, including phosphodiesterase type 5 inhibitor (PDE-5i), vacuum erection device (VED) and combination of both. RESULTS: 141 (75.4%) patients reported being sexually active in the six months before RP.122 (65.2%) patients wished to preserve sexual activity and 80 (42.8%) had interest in penile rehabilitation after RP. Penile rehabilitation rate was 30.5%. The patients with younger age (P<0.001), higher IIEF-5 score preoperatively (P=0.03) and no adjuvant therapy post-RP (P=0.01) were more acceptable for rehabilitation. Main reasons for refusal of rehabilitation included lack of sexual interest followed by high cost of treatment. The successful intercourse rate was not significantly different among three rehabilitation interventions (P=0.32). CONCLUSIONS: Less than one-third of Chinese RP patients accepted penile rehabilitation postoperatively. Patients' attitude towards rehabilitation was conservative because of many reasons from traditional Chinese culture, doctors and patients themselves. Penile rehabilitation was feasible and effective in Chinese RP patients.
