Ejaculatory and erectile function outcomes following holmium laser enucleation of the prostate.

PURPOSE: Holmium laser enucleation of the prostate (HoLEP) is a surgical treatment option for benign prostatic hyperplasia (BPH). Many men develop retrograde ejaculation postprocedure, but there is conflicting evidence regarding sexual function outcomes post-HoLEP. We sought to examine significant variations in patient-reported erectile and ejaculatory function within 12 months post-HoLEP. MATERIALS AND METHODS: We conducted a retrospective study for patients who underwent HoLEP between Nov 2018 and Feb 2022. Of the reviewed patients, 277 patients met inclusion criteria and completed pre and postoperative questionnaires, which included the Male Sexual Health Questionnaire- Ejaculatory Dysfunction (MSHQ-EJD) and the International Index of Erectile Function/Sexual Health Inventory for Men (IIEF-5/SHIM). Surveys were provided to patients up to 12 months postprocedure. Demographics and comorbidities associated with sexual dysfunction were collected. Responses to each question were analyzed to detect sub-categorical variations in sexual function as the secondary objective. Data was analyzed by using a linear mixed model. RESULTS: There was a significant decline in total scores for the MSHQ-EJD (8.70 pre-HoLEP vs. 6.58 post HoLEP, p ≤ 0.001) including a significant decline (p < 0.005) in questions 1-3 which assess ejaculatory ability, strength, and volume. There was not a significant decline in question 4 which assesses bother (2.552 pre-HoLEP vs. 3.119 post-HoLEP, p = 0.526). There was not a significant decline in the IIEF-5/SHIM postoperatively (11.51 pre-HoLEP vs. 13.327 post-HoLEP, p = 0.498). CONCLUSIONS: Patients undergoing HoLEP do not experience a decline in erectile function. Patients do experience a decline in ejaculatory function but did not find this bothersome.

Saline-assisted fascial exposure (SAFE) technique to improve nerve-sparing in robot-assisted laparoscopic radical prostatectomy.

OBJECTIVE: To provide a summary of our initial experience and assess the impact of the Saline-Assisted Fascial Exposure (SAFE) technique on erectile function (EF), urinary continence, and oncological outcomes after Robot-Assisted Laparoscopic Radical Prostatectomy (RALP). PATIENTS AND METHODS: From January 2021 to July 2022, we included patients with a baseline Sexual Health Inventory for Men (SHIM) score of ≥17 and a high probability of extracapsular extension (ECE), ranging from 21% to 73%, as per the Martini et al. nomogram. A propensity score matching was carried out at a ratio of 1:2 between patients who underwent RALP + SAFE (33) and RALP alone (66). The descriptive statistical analysis is presented. The SAFE technique was performed using two approaches, transrectal guided by micro-ultrasound or transperitoneal. Its principle entails a low-pressure injection of saline solution in the periprostatic fascia to achieve an atraumatic dissection of the neural hammock. Potency was defined as a SHIM score of ≥17 and continence as no pads per day. RESULTS: At follow-up intervals of 6, 13, 26, and 52 weeks, the SHIM score differed significantly between the two groups, favouring the RALP + SAFE (P = 0.01, P < 0.001, P < 0.001, and P = 0.01, respectively). These results remained significant when the mean SHIM score was assessed. As shown by the cumulative incidence curve, EF rates were higher in the RALP + SAFE compared to the RALP alone group (log-rank P < 0.001). The baseline SHIM and use of the SAFE technique were independent predictors of EF recovery. CONCLUSIONS: The use of the SAFE technique led to better SHIM scores at 6, 13, 26, and 52 weeks after RALP in patients at high risk of ECE who underwent a partial NS procedure.

Can nerve monitoring during radical prostatectomy improve functional outcomes? A randomised trial.

OBJECTIVE: To explore how the use of the ProPep® Nerve Monitoring System (ProPep Surgical, Austin, TX, USA) for intraoperative specific sparing of the pudendal nerve fibres influences postoperative functional outcomes after unilateral nerve-sparing (UNS) or non-nerve-sparing (NNS) robot-assisted radical prostatectomy (RARP). PATIENTS AND METHODS: We randomised 100 men undergoing UNS or NNS RARP to ProPep nerve monitoring during RARP (intervention) or standard of care RARP (control). Functional outcomes were assessed at 3, 6, and 12 months using the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), the International Prostate Symptom Score, the Danish Prostate Symptom Score, the International Index of Erectile Function, the Erection Hardness Scale, and 24-h pad tests. The primary outcome was the difference in ICIQ-SF score between the groups at 12 months. Secondary outcomes included differences in the remaining outcome measures and continence rates at all time points. Continence was defined as the use of no pads and the answer 'Never' to the question: 'How often do you experience urinary incontinence?' or a urine loss of <8 g on the 24-h pad test. RESULTS: A total of 82 patients were included in the per-protocol analysis at 12 months with 41 in each group. At 12 months the mean ICIQ-SF scores were 5.37 (95% confidence interval [CI] 3.71-7.03) and 5.66 (95% CI 4.05-7.27) for the intervention and control groups, respectively (P = 0.8). There were no statistically significant differences in any of the remaining outcomes. However, the continence rate was higher in the intervention group at 6 months (63% vs 44%, P = 0.09). CONCLUSIONS: Intraoperative nerve monitoring did not result in better functional outcomes following UNS or NNS RARP. Larger studies are needed to explore if ProPep can reduce the time to continence after RARP.

The effect of combination treatment with low-intensity shockwave therapy and daily tadalafil on severe erectile dysfunction: a double-blind, randomized, sham-controlled clinical trial.

BACKGROUND: Patients with severe erectile dysfunction (ED) remain the most challenging group in terms of available noninvasive treatment modalities. AIM: The study sought to assess the role of combination therapy with low-intensity shockwave therapy (LiST) and daily tadalafil 5 mg in a highly select group of patients with severe vasculogenic ED through a double-blind, randomized trial. METHODS: Forty-eight sexually active men were randomly assigned to 12 sessions of LiST 3 times weekly and tadalafil 5 mg once daily (n = 34) or sham therapy and tadalafil (n = 17) for 4 weeks. Patients were assessed at 1 and 3 months after completion of treatment. OUTCOMES: Improvement of erectile function was evaluated through the International Index of Erectile Function-Erectile Function domain (IIEF-EF) or 6-item IIEF and the Sexual Encounter Profile (SEP) diary. The primary outcome was the difference between the groups in the IIEF-EF at 3 months after completion of treatment. Secondary outcomes comprised (1) the difference between the groups in the IIEF-EF at 1 month after completion of treatment, (2) the difference between the groups in the "yes" responses to question 3 of the SEP diary at 1 and 3 months, and (3) the treatment-related adverse events. The number of patients attaining a minimal clinically important difference in the IIEF-EF (improvement of at least 7 points) was also assessed. RESULTS: After treatment, the absolute scores in the IIEF-EF were higher in patients receiving LiST and tadalafil vs sham therapy and tadalafil both at the 1-month (12.1 ± 2.4 vs 10.2 ± 1.7; P = .002) and at the 3-month (12.9 ± 2.1 vs 10.8 ± 1.8; P < .001) evaluation. Between the 2 groups, the proportion of "yes" responses to question 3 of the SEP diary was not statistically significant, whereas the number of patients attaining a minimal clinically important difference in the IIEF-EF was statistically significant only at the 3-month evaluation. No adverse events occurred. CLINICAL IMPLICATIONS: Application of LiST in patients with severe vasculogenic ED receiving daily dose tadalafil may further improve erectile function compared with tadalafil as a stand-alone treatment on the short term. STRENGTHS AND LIMITATIONS: Although we provided the first study in the field, severe vasculogenic ED was defined based on medical history and clinical examination and not based on penile ultrasound measures. CONCLUSION: The combination of 12 sessions LiST 3 times weekly and daily tadalafil for 4 weeks led to a 2-point difference in the IIEF-EF compared with sham therapy and daily tadalafil among patients with severe vasculogenic ED after 1 and 3 months from completion of treatment.

Retzius sparing robot-assisted radical prostatectomy: optimizing functional results.

PURPOSE: The aim of this study is to critically evaluate the existing body of evidence regarding the efficacy of Retzius-sparing radical prostatectomy (RS-RARP) in achieving improved functional outcomes. Moreover, we explored possible strategies to further optimize functional outcomes. METHODS: Following PRISMA guidelines, a systematic review (PROSPERO ID CRD42024539915) was performed on 9th September 2023 on PubMed, Scopus, and Web of Science. Only original articles in the English language reporting functional outcomes after RS-RARP were included. RESULTS: Overall, the search string yielded 99 results on PubMed, 122 on Scopus, and 120 on Web Of Science. After duplicate exclusion, initial screening and eligibility evaluation, a total of 47 studies were included in the qualitative analysis, corresponding to a cohort of 13.196 patients. All studies reported continence recovery. RS-RARP appeared to achieve better and faster continence recovery compared to S-RARP. However, it should be noted that continence definition was heterogeneous and not based on validated condition-specific questionnaires. Seven (15%) studies provided for any sort of rehabilitation for urinary incontinence after RS-RARP. 22 studies analyzed potency recovery rates, showing no difference between RS-RARP and S-RARP. The evaluation of this outcome poses a great challenge due to the lack of standardized assessment tools and reporting methods. Only two studies reported on the consistent use of post-operative PDE5i as penile rehabilitation. CONCLUSIONS: The current review highlights the satisfactory functional results of Retzius-sparing robot assisted radical prostatectomy, which holds true irrespective of disease stage and prostate volume, with promising results even in patients previously treated for BPH or in the salvage setting. How can we optimize those results? The answer does not probably lie in further refinement of the surgical technique, but in giving greater attention to patient counselling and rehabilitation strategies in order to minimize regret and maximize satisfaction.

Time-dependent analysis of erectile dysfunction in kidney transplant recipients: insights from four distinct time periods.

BACKGROUND AND INTENTION: Erectile dysfunction (ED) is an underappreciated clinical condition in men. This study aims to compare the dynamic changes in the distribution of ED among male kidney transplant recipients (mKTRs) in four epochs: end-stage renal disease period (ESRDp), early post-transplant period (EPTP), pre-COVID-19, and post-COVID-19. METHODS: General information was gathered through interviews, follow-ups, and medical records. The International Index of Erectile Function Questionnaire-5 was used to assess erectile function. The Mann-Whitney U test and chi-square test were used to analyze differences in ED strength. Univariate and logistic regression analyses were conducted to identify risk factors for ED. RESULTS: The database contains 230 mKTRs. In the ESRDp, 17.0% had normal erectile function, 53.5% had mild ED, 18.3% had moderate ED, and 11.3% had severe ED. In the EPTP, the distribution was 38.2% normal, 42.6% mild, 10.8% moderate, and 8.2% severe. In the pre-COVID-19 period, it was 34.3%, 47.3%, 10.4%, and 7.8%, and in the post-COVID-19 period, it was 23.0%, 45.6%, 21.3%, and 10.0%. Overall, erectile function improved after kidney transplant (KT). However, post-COVID-19, the proportion of erectile function significantly decreased compared to EPTP and pre-COVID-19 periods. Risk factors for post-pandemic ED included degree, Generalized Anxiexy Disorder-7, kidney donor type, postoperative time, hypertension and hemoglobin concentration. CONCLUSION: KT improves erectile function in mKTRs within 5 years, but post-SARS-CoV-2 viral infection, ED worsens due to altered risk factors. These findings inform future research for comprehensive ED prevention and management strategies in this population.

Effect of yoga as a complementary therapy in prostate cancer survivors: a systematic review.

PURPOSE: Currently, available evidence suggests a positive impact of yoga on physical and psychological well-being in patients across different types of cancer, especially breast cancer survivors. However, there are no available systematic reviews on the effects of yoga on male prostate cancer survivors. The objective of the current systematic review is to specifically examine the quality of life, feasibility, and other effects of yoga on prostate cancer survivors. METHODS: Bibliographic databases such as PubMed/Medline, CINAHL, EMBASE, Cochrane Library, and Google Scholar were searched for studies that were conducted till December 2022 to assess the effect of yoga on prostate cancer survivors. Studies that met predefined eligibility criteria were included. The quality of the included studies was assessed by the Cochrane risk of bias tool, and for single-arm studies, the Newcastle-Ottawa Scale was used. RESULTS: A comprehensive literature search yielded a total of 137 studies. After careful consideration, this review included five studies involving 129 prostate cancer survivors. The included studies were published between 2012 and 2022. This systematic review observed that yoga has the potential to enhance erectile function, reduce fatigue and urinary symptoms, alleviate psychological stress, boost immune function, and improve the overall quality of life in prostate cancer survivors. Furthermore, it demonstrates the feasibility of incorporating yoga into their regular routine. CONCLUSIONS: Yoga could be an effective complementary therapy in the management of physical and psychological symptoms experienced by prostate cancer survivors. However, until more comprehensive evidence becomes available, it would be premature to draw definitive conclusions about the effectiveness of yoga in the context of prostate cancer (PCa).

Sexual dysfunction in a sample of Egyptian patients with Parkinson's disease.

BACKGROUND: Sexual dysfunction (SD) is a common, yet underdiagnosed problem in Parkinson Disease (PD) patients. It can negatively impact their quality of life (QoL) and clinical outcome. we tried to assess SD in a group of Egyptian PD patients. METHODS: The study is a case-control, cross-sectional study that included 200 participants, consisting of 100 PD patients and 100 matched healthy controls. Social, demographic information, and clinical variables were collected from both groups. Sexual functions were assessed using the Arabic Female Sexual Function Index (ArFSFI), and the Arabic version of International Index of Erectile Function (IIEF). RESULTS: Women with PD scored worse on FSFI total score compared to controls (p < 0.001). Regarding the FSFI domains, they scored significantly lower in individual domains of desire (p < 0.001), arousal (p < 0.001), lubrication (p = 0.006), orgasm (p < 0.001), satisfaction (p < 0.001), and pain (p = 0.003), compared with controls. Men with PD scored worse on IIEF total scores compared to controls (p < 0.001). They showed significantly worse scores of erectile functions (p < 0.001), orgasmic function (p < 0.001), sexual desire (p < 0.001), intercourse satisfaction (p < 0.001), and overall satisfaction (p < 0.001). Both groups reported significant effect of SD on their QoL. There was a significant correlation between disease severity and SD. CONCLUSION: SD is common in PD patients. It negatively impacts their QoL and partnership. Healthcare professionals should initiate conversations about SD with the patients and provide appropriate education and treatment options.

Penile Elastography Versus Penile Duplex Ultrasonography in Diagnosing Non-Responders to Intracavernosal Injection: A Prospective Cohort Study.

OBJECTIVES: The current study aims to investigate the value of penile elastography in assessing the fibrotic changes in the corpora cavernosa. PATIENTS AND METHODS: Eighty participants were included in the study. These were divided into two equal groups: a study group (group 1) included patients with ED who did not respond to intracavernosal injection (ICI), and an age-matched control group (group 2) included age-matched subjects with normal erection. All subjects answered an International Index of Erectile Function-5 (IIEF-5) questionnaire. The first group was evaluated by two ICI trials of 1 mL Quadmix, each took place 1 week apart, followed by a color duplex/Doppler ultrasonography (CDDU) scan using also a 1 mL Quadmix. All the above was done a week before the penile shear wave elastography (SWE) scan. It comprised a 12-section scan of both corpora cavernosa. Each corpus was scanned in three different segments (proximal, mid-shaft, and distal), and in both longitudinal and transverse axes. RESULTS: Comparisons of the laboratory data were non-significant, apart from the glycosylated hemoglobin which proved significant (P value <.001) in both groups. Also, the IIEF-5 scores were significantly lower in the study group (P value <.001). Significantly higher SWE readings (indicating higher fibrotic) were found in the study group compared with the control group in almost all of the scanned segments and their combinations (P value <.05). CONCLUSION: SWE can effectively assess the fibrotic changes occurring in the corpora cavernosa. Hence, SWE could be utilized as a modality that helps diagnose patients with ED.

Psychosexual dysfunction in male patients with cannabis dependence and synthetic cannabinoid dependence.

OBJECTIVE: There are contradicting reports regarding the relationship between cannabis use and male sexual functions with almost no data about synthetic cannabinoids (SC) and its effect on male sexual functions. This study investigates psychological concerns related to male sexual functions among cannabis and SC users. The research aims to assess different sexual functions and aspects of sexual psychopathology in cannabis and SCs dependent men compared to controls. METHOD: Thirty male patients with cannabis dependence, thirty male patients with SCs dependence and thirty matched controls from the outpatient clinic of Kasr Al Ainy hospital, Egypt, were assessed using Structured Clinical Interview for DSM-IV TR Axis I Disorders (SCID-I), International Index of Erectile Function (IIEF), and Sexuality scale. RESULTS: The means of IIEF questionnaire in the cannabis and SC group were significant lower than the means of the control group (P < .001) except the orgasmic function in cannabis group (P = .052). In the SCs group, sexual depression was higher and preoccupation lower than the cannabis (P < .020; P < .003, respectively) and control groups (P < .001; P < .001, respectively). The duration and dose of intake of cannabis and SCs correlated significant with sexual esteem, sexual preoccupation and all domains of IIEF. CONCLUSION: Cannabis and SC dependence were associated with lower erectile function, sexual desire, intercourse satisfaction and overall satisfaction, and lower orgasmic functions in the SC group than controls. Both groups showed higher sexual depression, lower sexual esteem and sexual preoccupation than controls. SC has a higher negative impact on male sexual functions and psychopathology than cannabis.

Postoperative functional and cancer control evaluation of conventional and Retzius-sparing robot-assisted radical prostatectomy: Comparison of selected cases by propensity score matching.

AIM: Although many reports have shown that Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) is effective for postoperative urinary continence, the postoperative voiding status and sexual function associated with this technique have not yet been adequately compared with those associated with conventional RARP (C-RARP). In this study, the lower urinary tract function, erectile function, and cancer control after C-RARP and RS-RARP were compared chronologically. MATERIALS AND METHODS: We selected 50 cases of C-RARP and RS-RARP each by propensity score matching and evaluated them over time using various questionnaires. Urinary continence recovery rates and biochemical recurrence (BCR)-free survival rates were calculated using the Kaplan-Meier method and compared between the two groups using the log-rank test. RESULTS: When urinary continence was defined as 0 pads per day, 0 pads per day + 1 security linear, or ≤1 pad per day, the postoperative improvement in urinary continence was better with RS-RARP over the course of up to 1 year for all definitions. The International Consultation on Incontinence Questionnaire-Short Form total scores and the Overactive Bladder Symptom Scores were better in the postoperative RS-RARP group. There were no significant differences in the International Prostate Symptom Score total score, QOL score, and erectile hardness score between the two groups during the observation period. The BCR-free survival did not differ significantly between the two groups CONCLUSIONS: Postoperative urinary continence was better in the RS-RARP group than in the C-RARP group; however, the voiding function, erectile function, and cancer control did not differ significantly.

COVID-19 vaccination does not affect male sexual functions.

BACKGROUND: COVID-19 infection has been linked with erectile dysfunction, which has also raised apprehensions about the impact of COVID-19 vaccination on male sexual functions. The purpose of this study was to investigate the impact of COVID-19 vaccination on male sexual functions, such as erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction. METHODS: We used International Index of Erectile Function (IIEF) questionnaire for data collection. Mixed methods were adopted for this study, which consisted of Google online form distribution and the distribution of hard copies of the form to those who were not internet friendly. All data were entered in a spreadsheet and scores were assigned to each response according to the standard scores given in the IIEF questionnaire. Fifteen questions, one corresponding to each question in the IIEF questionnaire, were included to assess the impact of COVID-19 vaccination on each sexual function. RESULTS: In the first part of analysis, we calculated sexual function scores and men reporting low sexual function scores (~ 15%) were excluded, providing us with 465 individuals for further analysis. Regarding the impact of COVID-19 vaccination on male sexual functions, 71% individuals reported no impact, 3% reported a decline, 2.7% reported an improvement, and 23.3% could not assess the impact. We also performed analysis on the basis of age-groups of the participants and the duration after vaccination, finding that there was no impact irrespective of the age of subjects or the length of period after vaccination. CONCLUSIONS: COVID-19 vaccination does not affect male sexual functions, including erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall sexual satisfaction.

Impact of hypoxia on male reproductive functions.

Male reproductive functions, which include testicular steroidogenesis, spermatogenesis, and sexual/erectile functions are key in male fertility, but may be adversely altered by several factors, including hypoxia. This review demonstrates the impact of hypoxia on male reproductive functions. Acute exposure to hypoxia promotes testosterone production via stimulation of autophagy and upregulation of steroidogenic enzymes and voltage-gated L-type calcium channel, nonetheless, chronic exposure to hypoxia impairs steroidogenesis via suppression of the hypothalamic-pituitary-testicular axis. Also, hypoxia distorts spermatogenesis and reduces sperm count, motility, and normal forms via upregulation of VEGF and oxidative stress-sensitive signaling. Furthermore, hypoxia induces sexual and erectile dysfunction via a testosterone-dependent downregulation of NO/cGMP signaling and upregulation of PGE1/TGFß1-driven penile endothelial dysfunction. Notably, hypoxia programs male sexual function and spermatogenesis/sperm quality via feminization and demasculinization of males and oxidative stress-mediated alteration in sperm DNA methylation. Since oxidative stress plays a central role in hypoxia-induced male reproductive dysfunction, studies exploring the effects of antioxidants and upregulation of transcription of antioxidants on hypoxia-induced male reproductive dysfunction are recommended.

Effect of aerobic exercise on erectile function: systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: The health benefits of regular aerobic exercise are well established, although there is limited high-quality evidence regarding its impact on erectile function. AIM: To determine the effect of aerobic exercise on erectile function in men and to identify factors that may influence this effect. METHODS: This systematic review and meta-analysis included randomized controlled trials that evaluated the effects of aerobic exercise on erectile function via the Erectile Function domain of the International Index of Erectile Function (IIEF-EF). The mean difference in IIEF-EF scores between the aerobic exercise and nonexercising control groups was estimated by a random-effects meta-analysis. Meta-regression was used to evaluate the association of moderator variables on meta-analysis results. OUTCOMES: The IIEF-EF score is reported on a 6-30 scale, with higher values indicating better erectile function. RESULTS: Among 11 randomized controlled trials included in the analysis, aerobic exercise resulted in statistically significant improvements in IIEF-EF scores as compared with controls, with a mean difference of 2.8 points (95% CI, 1.7-3.9; P < .001) and moderate heterogeneity among studies (I2 = 53%). The effect of aerobic exercise on erectile function was greater in men with lower baseline IIEF-EF scores, with improvements of 2.3, 3.3, and 4.9 points for mild, moderate, and severe erectile dysfunction, respectively (P = .02). The meta-analysis results were not influenced by publication bias or individual study effects. CLINICAL IMPLICATIONS: Health care providers should consider recommending regular aerobic exercise as a low-risk nonpharmacologic therapy for men experiencing erectile difficulties. STRENGTHS AND LIMITATIONS: The primary strength of this review was the generation of level 1 evidence on a topic of general interest regarding sexual health in men. However, the included studies evaluated diverse groups, which may complicate data interpretation for specific segments of the population. CONCLUSION: Regular aerobic exercise can improve the erectile function of men, particularly those with lower baseline IIEF-EF scores.

Long-term efficacy and safety of extracorporeal shock wave therapy (Li-ESWT) protocols in the treatment of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) patients.

AIM: This study aims to evaluate the long-term effectiveness of Li-ESWT in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) patients and to compare the effect of treatment protocol differences on success. METHOD: Between December 2019 and January 2021, the data of male patients over the age of 18 who applied to the urology outpatient clinic with CP/CPPS symptoms were retrospectively analyzed. International Prostate Symptom Index (IPSS) and International Index of Erectile Function-Erectile Function (IIEF-EF) questionnaires were filled in for the evaluation of erectile function. All patients received treatment with the Medispect Bold Li-ESWT. The treatment responses of the patients who received a total of 6 sessions from one session per week and 12 sessions from two sessions per week were compared. RESULTS: A total of 129 patients were included in the study. Significant improvements were observed in the NIH-CPSI, IPSS, and IIEF-EF scores at the third month follow-ups of the patients after EWST (p < 0.001 for each). Improvements in scores were also found to be significant in NIH-CPSI, IPSS, and IIEF-EF at the 12th month evaluation. When the patients were evaluated according to the number of Li-ESWT sessions they received, the IPSS score average of the patient group who received 12 sessions of Li-ESWT was found to be lower than the patients who received 6 sessions of Li-ESWT (5.67 ± 2, 30 vs 4.51 ± 2.21; p = 0.005). There was no significant difference in the IIEF-EF and IPSS scores in the 12th month evaluations of the patients, but the mean NIH-CPSI score was found to be higher in the group that received 12 sessions of Li-ESWT (p = 0.003). CONCLUSION: Li-ESWT in the treatment of CP/CPPS patients shows positive improvements in urinary symptoms, erectile function, and quality of life in patients unresponsive to other medical treatments. The increase in the number of sessions does not seem to influence the symptoms of the patients.

Atherosclerosis of the iliac arteries for the prediction of erectile dysfunction and epistaxis in men undergoing abdominal CT scan.

BACKGROUND: To investigate the association between erectile dysfunction (ED) as well as epistaxis (ES) in relation to the extent of iliac atherosclerosis. METHODS: In this retrospective cross-sectional study, all consecutive male patients treated at our institution from 01/2016 to 12/2020 undergoing abdominal CT scan were evaluated. Patients (n = 1272) were invited by mail to participate in the study in returning two questionnaires for the evaluation of ED (IIEF-5) and ES. Patients who returned filled-in questionnaires within a 3-month deadline were included in the study. The extent of atherosclerosis in the common iliac artery (CIA) and the internal iliac artery (IIA) was assessed by calcium scoring on unenhanced CT. Stratification of results was performed according to reported IIEF-5 scores and consequential ED groups. RESULTS: In total, 437 patients (34.4% of contacted) met the inclusion criteria. Forty-two patients did not fulfill predefined age requirements (< 75 years) and 120 patients had to be excluded as calcium scoring on nonenhanced CT was not feasible. Finally, 275 patients were included in the analysis and stratified into groups of "no-mild" (n = 146) and "moderate-severe" (n = 129) ED. The calcium score (r=-0.28, p < 0.001) and the number of atherosclerotic lesions (r=-0.32, p < 0.001) in the CIA + IIA showed a significant negative correlation to the IIEF-5 score, respectively. Patients differed significantly in CIA + IIA calcium score (difference: 167.4, p < 0.001) and number of atherosclerotic lesions (difference: 5.00, p < 0.001) when belonging to the "no-mild" vs. "moderate-severe" ED group, respectively. A multivariable regression model, after adjusting for relevant baseline characteristics, showed that the number of atherosclerotic CIA + IIA lesions was an independent predictor of ED (OR = 1.05, p = 0.036), whereas CIA + IIA calcium score was not (OR = 1.00031, p = 0.20). No relevant correlation was found between ES episodes and IIEF-5 scores (r=-0.069, p = 0.25), CIA + IIA calcium score (r=-0.10, p = 0.87) or number of atherosclerotic CIA + IIA lesions (r=-0.032, p = 0.60), respectively. CONCLUSIONS: The number of atherosclerotic lesions in the iliac arteries on nonenhanced abdominal CT scans is associated with the severity of ED. This may be used to identify subclinical cardiovascular disease and to quantify the risk for cardiovascular hazards in the future. TRIAL REGISTRATION: BASEC-Nr. 2020 - 01637.

The Change of Erectile Function Post Recovery from COVID-19 Infection.

INTRODUCTION: We assess the correlation between COVID-19 infection and erection and evaluate the effect of aging and comorbidities on the male sexuality of patients with COVID-19 infection. METHODS: 100 patients were enrolled and diagnosed with COVID-19 based on reverse transcription-polymerase chain reaction tests of oropharyngeal and nasopharyngeal swabs according to the WHO guidelines. The International Index of Erectile Function (IIEF-5) questionnaire was used to evaluate sexual function. RESULTS: Patients were divided into two groups: the first group of 42 patients <50 years of age with a mean age (±SD) of 35.83 ± 7.8 and the second group of 58 patients ≥50 years of age with a mean age of 58.64 ± 7.7. The mean (±SD) IIEF in the first group pre-COVID-19 infection was 14.2 ± 2.37 while post-COVID-19 was 8.7 ± 2.77, 11.3 ± 2.9, 12.1 ± 3.02 at 1, 3, 6 months, respectively (p < 0.001), while in the second group, the mean (±SD) IIEF pre-COVID-19 infection was 10.04 ± 4.62 while post-COVID was 5.0 ± 2.1, 6.56 ± 2.6, 8.18 ± 2.04 at 1, 3, 6 months, respectively (p < 0.001). On multivariate analysis, old patients infected with COVID-19 and associated with comorbidities such as diabetes mellitus (OR = 8.53, CI = 0.00-2.01), hypertension (OR = 3.908, CI = 0.000-3.07), ischemic heart disease (OR = 2.863, CI = 0.000-2.68), and liver disease (OR = 0.670, CI = 0.000-1.670) were significantly correlated to erectile dysfunction (p < 0.001). CONCLUSION: COVID-19 significantly affects erection mostly in older patients with comorbidities, leading to subsequent use of oral and intracavernosal injection therapy for erectile dysfunction.

Nerve-Sparing Laparoscopic Cystoprostatectomy Based on Inferior Hypogastric Plexus Dissection: Our Initial Experience.

INTRODUCTION: The aim of this study was to implement our technique for the initial dissection of the inferior hypogastric plexus and protection of the autonomic nerve supply to the corpora cavernosa in laparoscopic radical cystoprostatectomy with an orthotopic ileal neobladder and report the initial outcomes. METHODS: Eleven normally potent patients with preoperative cT2N0 bladder cancer who underwent bilateral nerve-sparing laparoscopic cystoprostatectomy performed by the same surgeon were selected from May 2018 to September 2020. In this procedure, the anterior part of the inferior hypogastric plexus was dissected first between the prehypogastric nerve fascia and rectal proper fascia medial to the distal ureter. Then the Denonvilliers' fascia and the nerves around the prostate were preserved according to current intrafascial principles. The preliminary operative, oncologic, and functional results are presented. RESULTS: The median follow-up duration was 18 months. We observed early and late complications in 5 patients, but none exceeded grade III. Of the 11 patients, ten gained daytime continence (90.9%), and 8 (72.7%) showed nocturnal continence at the last follow-up. Regarding postoperative potency, 10 of the 11 patients (90.9%) remained potent with or without oral medications, excluding one who had partial tumescence but did not follow our recommendations regarding medication use. No local recurrence or positive surgical margins were noted. CONCLUSION: In addition to emphasizing our cavernosal nerve-sparing procedure, this report on the precise dissection and protection of the inferior hypogastric plexus could be of clinical significance, providing potentially ideal short-term functional results.

[Application of a modified vascular blocking technique in intrafascial nerve-sparing laparoscopic radical prostatectomy].

OBJECTIVE: To investigate the clinical effect of a modified vascular blocking technique in intrafascial nerve-sparing laparoscopic radical prostatectomy (INLRP). METHODS: We retrospectively studied the clinical data on 13 cases of INLRP completed via a modified vascular blocking technique between July 2021 and August 2022. The patients ranged in age from 64 to 73 (68.8 ± 3.15) years, with elevated PSA of 4.71－16.12 (9.71 ± 3.50) µg/L preoperatively. Prostate cancer was confirmed in all the cases by ultrasound-guided perineal prostate needle biopsy, with Gleason 6 in 7 cases and Gleason 7 in 6 cases. MRI revealed no preoperative tumor breakthrough in the prostatic capsule or pelvic lymph node metastasis. All the patients received INLRP with a modified superficial suture dorsal vein complex (DVC) combined with lateral prostatic pedicle vascular blocking. RESULTS: Prostatic capsule rupture occurred in 1 case during the operation, with positive resection margin indicated by rapid intraoperative frozen biopsy, so the lateral fascia resection was modified. No positive resection margin was found in any of the cases in postoperative pathological examinations. Urinary continence was restored in 8 cases immediately after surgery and in the other 5 within 2 weeks after catheter removal. At 1 month after surgery, all the patients were medicated with low-dose tadalafil (5 mg qd), and IIEF-5 scores of >15 were achieved in 4 cases (31%) at 1 month and in another 8 (62%) at 3 months postoperatively. CONCLUSION: INLRP via modified vascular blocking showed the advantages of desirable intraoperative bleeding control and postoperative tumor control, restoration of urinary continence and relatively satisfactory recovery of erectile function. However, due to the small sample size, short follow-up time and lack of control, our findings need to be further verified by more clinical studies.

[PKEP with complete preservation of the urethral mucosa in the 11－1 o'clock position improves urinary continence and protects erectile function in BPH patients].

OBJECTIVE: To evaluate the effect of transurethral plasmakinetic enucleation of the prostate (PKEP) with complete preservation of the urethral mucosa in the 11－1 o'clock position on urinary continence and erectile function in BPH patients. METHODS: We retrospectively analyzed the clinical data on 84 cases of BPH treated by traditional PKEP (group A, n = 48) or modified PKEP with complete preservation of the urethral mucosa in the 11－1 o'clock position (group B, n = 36) from January 2017 to December 2021. All the patients had sexual activities within three months preoperatively. We followed up the patients for 12 months after surgery and compared the baseline, surgery-related and follow-up data between the two groups of patients. RESULTS: There were no statistically significant differences between the two groups of patients in age, disease duration, prostate volume, preoperative postvoid residual urine (PVR), preoperative maximum urinary flow rate (Qmax), IPSS, PSA level, QOL scores or IIEF-5 scores, nor in the operation time, intraoperative hemoglobin decrease, volume of resected tissue, bladder flushing time, postoperative hospital stay, or postoperative improvement of Qmax and IPSS. The rate of urinary continence was significantly higher in group B than in A at 1 month postoperatively (66.67% ï¼»24/36ï¼½ vs 43.25% ï¼»20/48ï¼½, P = 0.025) and so were IIEF-5 scores at 6 months (16.69 ± 3.21 vs 15.27 ± 2.74, P = 0.032) and 12 months (18.04 ± 2.04 vs 16.96 ± 2.54, P = 0.039), while the incidence rate of retrograde ejaculation markedly lower in the former than in the latter group at 6 months (33.33% ï¼»12/36ï¼½ vs 56.25% ï¼»28/48ï¼½, P = 0.018) and 12 months (25% ï¼»9/36ï¼½ vs 47.92% ï¼»23/48ï¼½, P = 0.027). At 1, 3, 6 and 12 months after surgery, the patients in group B also showed remarkably higher QOL scores than those in group B (2.61 ± 0.81 vs 2.12 ± 0.69, P = 0.005; 2.24 ± 0.66 vs 1.94 ± 0.51,P = 0.026; 2.12 ± 0.83 vs 1.80 ± 0.53,P = 0.047; and 1.94 ± 0.65 vs 1.72 ± 0.58, P = 0.038). CONCLUSION: Modified PKEP with complete preservation of the urethral mucosa in the 11－1 o'clock position can improve urinary continence, protect erectile function and ameliorate QOL in patients with BPH.
