Efficacy and Safety of Different Modalities for Treatment of Erectile Dysfunction in Chronic Renal Failure Patients

Background Erectile dysfunction has been found to be significantly more common in men with chronic kidney disease (CKD) than in the general population. Objective of the Study Detection of the safest and most effective medical treatment of erectile dysfunction(ED) in chronic renal failure patients. Patients and Methods . This study was conducted at Ain Shams University Hospitals with a sample size of 60 patients: 15 patients per group. We assessed the improvement in the erectile function through assessment of IIEF (International Index of Erectile Function) score and EHS (Erection Hardness Scale) score pre- and post-administration of the drugs used in the study (oral sildenafil, oral vardenafil, oral tadalafil and intracavernosal injection of alprostadil). Results There is a statistically significant increase in IIEF score post-administration of the drugs used in this study with p value of < 0.001 and a mean difference of 6.92. The mean score of IIEF pre-administration of the drugs used was 8.13 and post-administration was 15.05. There is also a statistically significant difference in EHS score with p value of < 0.001 and mean difference of 1.4. The mean score of EHS pre-administration of the drugs was 1.22 and post-administration was 2.62. From the four drugs used in this study, Alprostadil showed the highest improvement in IIEF and EHS scores. The study also showed a negative correlation between age, duration of haemodialysis and serum creatinine with erectile function. In addition, there was a statistically significant decrease in pre- and- post-treatment IIEF and EHS scores in diabetic cases than in the non-diabetic cases. Conclusion There is high incidence of ED in CKD patients. The drugs used in the study showed improvement in the erectile function with mild side effects. Alprostadil had the best IIEF and EHS scores amongst the four drugs.

Sexual dysfunction is more common among men who have high sperm DNA fragmentation or teratozoopermia

Men in couples that have experienced pregnancy loss have a higher risk of sexual dysfunction. Semen quality impairment is common in men of couples with pregnancy loss. The objective of this article is to evaluate the differences in the incidence of male sexual dysfunction in a cohort of pregnancy loss couples with different types of semen quality impairment. A cross-sectional analysis of 426 men who attended our outpatient clinic for couples’ pregnancy loss, those without genetic abnormalities were included in the final analysis covering June 2021 to October 2021. The patients were divided into 5 groups according to type of semen quality impairment: normozoospermia group (group normal; N = 161), high sperm DNA fragmentation group (group high-SDF; N = 87), isolated asthenozoospermia group (group iAstheno; N = 45), isolated teratozoopermia group (group iTerato; N = 44), and ≥ 2 abnormal sperm parameters group (group multiple; N = 89). All subjects underwent a complete physical inspection, including palpation of the male genitalia and semen analysis. Validated assessment tools for erectile dysfunction (the International Index of Erectile Function -IIEF-5) and anxiety (the seven-item Generalized Anxiety Disorder Scale- GAD-7) were also used. Men with high sperm DNA fragmentation and isolated teratozoopermia were associated with increased erectile dysfunction risk when compared with normozoospermic men, with an OR of 2.75 [1.49–5.09; p = 0.001] and 2.44 [1.22–5.31; p = 0.024], respectively. It is interesting to note that there was no difference in prevalence of erectile dysfunction between Group iAstheno and Group normal (20.0% vs. 18.0%; OR = 1.24 [0.52–2.97]; P = 0.625). More than half (50.6%) of the participants in Group high-SDF reported sexual intercourse less than once per week, much more than those in the normozoospermia group (23.2%, p < 0.05), followed by Group iTerato (44.4%) and Group multiple (46.1%). GAD-7 scores increased slightly but significantly among groups when compared with Group normal. Not surprisingly, GAD-7 scores remained higher in Group high-SDF. In males of pregnancy loss couples, men with high sperm DNA fragmentation and teratozoopermia suffer from a higher incidence of erectile dysfunction. This phenomenon is not significant in men with isolated asthenozoospermia. Proper counseling and treatment of impaired semen quality are warranted.

Prevalence of sexual dysfunction among the male populations who seeking medical care for infertility, pregnancy loss and preconception care: a cross-sectional study

The link between sexual dysfunction and male infertility has been well established. In addition to male infertility, male patients with couple pregnancy loss and preconception care are the most frequent reasons for the treatment of andrology outpatients. However, there is a paucity of information simultaneously investigating male sexual dysfunction in these males with different reproduction situations. A cross-sectional study was performed in consecutive series of 1256 participants, including 509 men with infertility, 437 couples with pregnancy loss, and 310 men for preconception care. All men completed a questionnaire on baseline demographic information, sexual behavior characteristics and validated research tools, including Premature Ejaculation Diagnostic Tool, seven-item Generalized Anxiety Disorder Scale, and International Index of Erectile Function. The prevalence of erectile dysfunction and premature ejaculation was 30.6%, 20.8% in the infertility population and 27.0%, 18.5% in pregnancy loss individuals, was much lower in preconception care men, at 9.3%, 11.9% (p < 0.05), respectively. Infertility and pregnancy loss couples were more biased toward choosing timed intercourse than preconception care couples, with rates of 19.6% in Infertility group and 17.4% in pregnancy loss groups, versus 10.0% (p < 0.05) in preconception care couples. The infertile and pregnancy loss men also reported higher rate of anxiety state than the preconception care group. The prevalence of erectile dysfunction increased gradually with the duration of infertility and the frequency of pregnancy loss, with a highest odds ratio of 7.346 (95% CI:4.329–12.467; P < 0.001) among men with ≥5 years of infertility, 6.282 (95% CI:3.446–11.453; P < 0.001) among couples ≥3 pregnancy loss when compared with preconception care group. The prevalence of erectile dysfunction, premature ejaculation and timed intercourse were comparable in pregnancy loss and infertile males, were all noticeably higher than preconception care group. There was also a trend toward a higher incidence of erectile dysfunction with longer duration of infertility or the more frequent of pregnancy loss.

Comparative study of tamsulosin versus tadalafil in benign prostatic hyperplasia patients with lower urinary tract symptoms. A prospective randomized study.

Introduction:Benign prostatic hyperplasia (BPH) is one of the common causes of lower urinary tract symptoms (LUTS) in aging men. Men with LUTS have a higher incidence of erectile dysfunction (ED), and LUTS themselves represent an independent risk factor for ED, triggering a significant negative impact on quality of life.Materials and Methods:A total of 92 patients were randomly assigned to two groups. Groups I and II had 45 and 47 patients, two patients from Group I and three patients from Group II did not follow and were excluded from the study. Patients in Group I received 0.4 mg of tamsulosin and Group II patients received 5 mg tadalafil. Patients were assessed at baseline, 3 months, and at 6 months after receiving treatment. Treatment efficacy was measured by a change in Qmax, post void residual urine (PVR), International Prostate Symptom Score (IPSS), and Sexual Health Inventory for Men (SHIM) score at 3 months and 6 months.Results:Baseline parameters between the two groups were similar. Mean Qmax improved by 7 ml/s at 3 months to 9.44 ml/s at 6 months in Group I versus 4.73 ml/s at 3 months to 6.46 ml/s at 6 months in Group II (P = 0.739). Mean PVRU decreased by 35.53 ml at 3 months to 47.23 ml at 6 months in Group I versus 44.98 at 3 months to 58.28 ml at 6 months in Group II (P = 0.102). IPSS score improved by 4.24 points at 3 months to 7.22 points at 6 months in Group I versus 4 points at 3 months to 5.02 points at 6 months in Group II (P = 0.336). SHIM score improved by 0.7 points 16.2 at 3 months to 0.8 points at 6 months in Group I versus 6.12 points at 3 months to 6.3 points at 6 months (P < 0.001).Conclusion:When both groups were compared, tadalafil showed statistically similar improvements in Qmax, PVRU, and IPSS score, but statistically significant improvement was observed with tadalafil in SHIM score compared with tamsulosin in treating LUTS secondary to BPH. Our study provides evidence that once daily tadalafil 5 mg is well tolerated and can be considered for the treatment of LUTS secondary to BPH especially in patient with ED.

Erectile Dysfunction in Men Burdened with the Familial Occurrence of Coronary Artery Disease.

Erectile dysfunction (ED) and coronary artery disease (CAD) share common risk factors, some of which have genetic backgrounds, while others may be stimulated by family lifestyle. We investigated the impact of the familial occurrence of CAD on the presence of ED and the presence of classic risk factors for ED in men with CAD. This cross-sectional observational study involved 751 men with CAD who were subjected to cardiac rehabilitation. Overall, 75.63% of the men had ED. CAD was diagnosed in 39.28% of the studied men’s relatives. ED was less frequent in the men with familial CAD than in those without (71.53% vs. 78.29%). Similar relations were observed for the presence of CAD in parents (70.43% vs. 78.34%) and the father (69.95% vs. 77.46%). The International Index of Erectile Function 5 score was significantly higher in patients with familial CAD (median (interquartile range); 17 (12–22) vs. 16 (10–21); p = 0.0118), in parents (18 (12–22) vs. 16 (10–20); p = 0.021), and in the father (18 (12–22) vs. 16 (10–21); p = 0.0499). Age and education minimized the effect of familial CAD. Familial CAD increased the incidence of hypertension, dyslipidemia, and smoking but not sedentary lifestyle. Despite the higher prevalence of selected risk factors for ED in men with familial CAD, a higher incidence of ED was not observed.

Relationship between metabolic syndrome and acquired premature ejaculation

Objectives The aim of the study was to investigate the relationship between metabolic syndrome (MetS) with its components and acquired premature ejaculation (APE). Background PE has recently received considerable attention. It adversely affects the quality of life of both partners. PE represents the most common sexual dysfunction in sexually active men. Studies proved higher incidence of erectile dysfunction among patients with MetS, but the relation of the latter to APE has not receive much attention yet. Patients and methods Our case–control study included 50 individuals who were classified into two groups, with 25 individuals each: MetS group and control group. Both groups are age matched (30–60 years old). All men in both groups were in continuous stable marriage with no marital conflict. They are free of diseases, taking no drugs, did not have operations before, and did not have congenital anomaly that might affect their sexual function (except the manifestations of MetS in the case group). All the participants underwent the intravaginal ejaculatory latency time (IELT) assessment and did MetS component measurements. Results The results of our study showed significantly lower IELT in the MetS group compared with the control (2.80 ± 1.384 vs. 4.52 ± 1.782 min, respectively, P = 0.0001). Arabic index of premature ejaculation score was found to be significantly lower in cases (18.32 ± 7.663) compared with controls (30.32 ± 6.46), confirming the presence of APE caused by MetS. IELT was found to be negatively correlated with BMI, fasting blood sugar, and triglycerides, but not high-density lipoprotein. Conclusion MetS can be considered as an independent predisposing factor for development of APE. Effective prevention and treatment of MetS could be important for APE prevention.

Significant relationship between parameters measured by transrectal color Doppler ultrasound and sexual dysfunction in patients with BPH 12 months after TURP

BackgroundA link between sexual dysfunction and lower urinary tract symptoms due to benign prostatic hyperplasia (BPH) has been noticed. Transurethral resection of the prostate (TURP) remains the standard treatment for symptomatic BPH, whether TURP causes sexual dysfunction is still uncertain. In this retrospective study, we investigated the relationship between parameters measured by color Doppler ultrasound (CDU) and sexual dysfunction in patients with BPH 12 months after TURP.MethodsThe parameters include presumed circle area ratio (PCAR), maximal horizontal area of seminal vesicles (MHA), resistive index of the prostate (RIP), and peak systolic velocity in the flaccid penis (PSV). The international prostate symptom score was used to evaluate the lower urinary tract symptoms and the five-item version of the International Index of Erectile Function was used to evaluate sexual function before and after TURP.ResultsOf the 103 patients without sexual dysfunction before TURP, 11 (10.7%) had erectile dysfunction (ED) after TURP. These 11 patients had significantly lower PCAR, RIP, PSV and MHA than those without ED. The patients with retrograde ejaculation after TURP had significantly lower PCAR than those without retrograde ejaculation, and the patients with premature ejaculation after TURP had significantly lower MHA than those without premature ejaculation. Comparing the parameters between baseline and after TURP, PCAR, RIP, and MHA decreased significantly in the patients with sexual dysfunction, but no significant differences were noted in the patients without sexual dysfunction after TURP.ConclusionsMore extended TURP can lead to a higher incidence of ED and retrograde ejaculation in BPH patients without sexual dysfunction before TURP. Patients with a lower volume of seminal vesicles after TURP may have a higher incidence of premature ejaculation.

Erectile dysfunction in patients with first-episode psychosis.

Sexual dysfunction is more prevalent in psychotic patients than in the nonpsychotic population. The objective of this study was to identify correlations between serum prolactin levels, testosterone levels and erectile dysfunction in patients with first-episode psychosis (n=40) compared to age-matched healthy controls (n=40). All subjects underwent clinical evaluation, international index of erectile function (IIEF5) score assessment and measurement of serum prolactin and total testosterone levels. In first-episode psychotic patients, the IIEF-5 score and total testosterone levels were significantly lower, while serum prolactin levels were higher. We concluded that men with first-episode psychosis are at an increased risk for development of erectile dysfunction, and increased duration of untreated psychosis leads to a higher incidence of erectile dysfunction and hyperprolactinemia.

The relation between pelvic trauma (fractured pelvis) with posterior urethral distraction injury associated with erectile dysfunction

Background: The aim was to study the relation between posterior urethral distraction injury due to pelvic trauma (fractured pelvis) with erectile dysfunction and to do the clinical assessment of Erectile dysfunction by penile Doppler study for assessment of peak flow velocity. Material and Methods: Total number of cases included in the study was 13, out of which 5 patients belonged to young (<30 years) age group, 5 patients belonged to middle (30-50 years) age group and 3 patients belonged to old age group. Out of the total 13 patients, 8 patients had pelvic fracture associated with urethral injury and 5 patients had traumatic urethral stricture without pelvic fracture. Results: Out of 8 patients of pelvic fracture with urethral injury, all 8 developed erectile dysfunction after trauma. While among 5 patients of traumatic urethral stricture without pelvic fracture, 3 patients developed erectile dysfunction after trauma. While in traumatic urethral injury without pelvic fracture, amongst 3 patients who had erectile dysfunction, 2 patients had reduced flow on penile Doppler ultrasound and were classified as vascular erectile dysfunction while 1 patient was having a normal flow on penile Doppler ultrasound and was classified as neurogenic/psychological erectile dysfunction. Conclusion: Pelvic fracture associated urethral injury has a high incidence of erectile dysfunction. Vascular erectile dysfunction in such patients is more common than neurogenic/psychological erectile dysfunction. And postoperatively (urethroplasty), there is no significant decrease in penile colour doppler vascularity in such patients.

Association of erectile dysfunction and type II diabetes mellitus at a tertiary care centre of south India

Background and aimsErectile Dysfunction (ED) is more common in diabetic men and, unfortunately, occurs at an earlier age in diabetic patients when compared with the general population. The study aims to evaluate the independent predictors of ED in adult men with type 2 diabetes mellitus (DM) at a tertiary care center of South India. MethodsA total of 720 men aged 30–70 years who had been diagnosed with type 2 DM were enrolled for the study from January 2017 to January 2020 from the outpatient diabetes clinic of the Hospital. All patients completed the abridged version of the International Index of Erectile Function (IIEF-5) questionnaire. ResultsThe mean age of the patients was (58.4 ± 7.8 years). 68.6% of subjects had varying degrees of erectile dysfunction, of which 54.6% had moderate to severe ED. 55.8% had poor glycemic control (HbA1c ≥ 7%). Subjects with ED had a longer duration of DM than those without ED (mean DM duration was 8.1 ± 4.9 years versus 4.4 ± 3.5 years; p < 0.001). Longer duration of DM, poor glycemic control, hypertension, peripheral arterial disease, testosterone deficiency were all independent predictors ED (p < 0.05). ConclusionsA high incidence of erectile dysfunction was observed in type 2 DM patients attending the diabetic clinic, and over half of the people affected were of moderate-to-severe in intensity. Poor glycemic control, testosterone deficiency, peripheral arterial disease were the modifiable risk factors for ED in diabetic subjects. At the same time, a longer duration of type 2 DM was noticed as a glaring non-modifiable risk factor, according to our study.

End-to-side Somatic-to-autonomic Nerve Grafting to Restore Erectile Function and Improve Quality of Life After Radical Prostatectomy

BackgroundRadical prostatectomy (RP) is recommended for the treatment of men with clinically localised prostate cancer. However, RP is associated with a high incidence of erectile dysfunction (ED), which can impact the quality of life (QoL) significantly. ObjectiveTo evaluate the effectiveness of end-to-side nerve grafting surgery to restore erectile function and improve sexual QoL in men with ED after RP. Design, setting, and participantsA retrospective review of a single-centre experience of nerve grafting in men with ED following RP was performed. Seventeen men had surgery between March 2015 and October 2017 in Melbourne, Australia, which fulfilled study inclusion and exclusion criteria. InterventionMicrosurgical bilateral end-to-side nerve grafts from a selective fascicular neurotomy of the femoral nerve to the penile corpora cavernosa. Outcome measurements and statistical analysisResults were serially measured utilising the International Index of Erectile Function (IIEF-5) and the sexual domain of Expanded Prostate Cancer Index Composite (EPIC-26). The proportion and 95% confidence interval (CI) of men recovering sexual function following nerve grafting were determined. Results and limitationsAll patients had ED following their RP. Median age at nerve grafting was 64yr (interquartile range [IQR] 60–66yr). Median time between nerve- and non-nerve-sparing RP, and nerve grafting was 2.4 (IQR 2.1–3.1) and 2.2 (IQR 1.7–5.1)yr, respectively. Median follow-up was 18 (IQR 15–24) mo. At 12mo after nerve grafting, 71% (95% CI 44–90%) of patients had erectile function recovery sufficient for satisfactory sexual intercourse, and 94% (95% CI 71–99%) and 82% (95% CI 57–96%) had clinically significant improvements in sexual function and reduced bother, respectively. There were two minor wound infections. Limitations include the retrospective study design. ConclusionsEnd-to-side nerve grafting restored erectile function in 71% of men with ED following RP, supporting previous findings. Of the men, 94% had clinically relevant improvements in sexual QoL. We recommend multicentre implementation of post-RP nerve grafting into clinical practice with appropriate data collection to confirm its efficacy and feasibility. Patient summaryWe provide confirmatory evidence that end-to-side nerve grafting surgery restored erectile function and improved sexual quality of life in, respectively, 71% and 94% of men with erectile dysfunction following radical prostatectomy.

Tighter Blood Pressure Control Is Associated with Lower Incidence of Erectile Dysfunction in Hypertensive Men

IntroductionTighter blood pressure control is widely thought to be associated with better erectile function, although the preponderance of data is limited to dichotomous representations of hypertension without an attempt to look at degree of blood pressure control. AimTo determine the association between optimal blood pressure control over time and the development of erectile dysfunction (ED) in a cohort of potent men. MethodsWe performed a retrospective cohort study of newly diagnosed hypertensive men without major medical comorbidities in an integrated healthcare system. Patients were stratified by exposure to hypertension, with varying levels of blood pressure control, as measured by ordinal categories of systolic blood pressure and deviation from the mean systolic pressure. Main Outcome MeasuresIncidence of ED was defined by at least 2 primary care or urology diagnoses of ED in our electronic health records within 2 years, at least 2 filled prescriptions for ED medications within 2 years, or 1 diagnosis of ED and 2 filled prescriptions for ED medications. ResultsWe identified 39,320 newly diagnosed hypertensive men. The overall incidence for ED was 13.9%, with a mean follow-up of 55.1 ± 28.7 months. Higher average systolic blood pressure was associated with a higher risk of ED in a dose-dependent manner (trend test, P < .001). Wide variation in blood pressure control was associated with a higher incidence of ED (OR [95% CI]; 1.359 [1.258–1.469]) and a shorter time to the development of ED (log rank, P < .0001). Clinical ImplicationsWe believe these data may serve as a motivator for hypertensive men to better adhere to their hypertension treatment regimen. Strength & LimitationsThe retrospective nature of our study precludes us from drawing more than an association between tighter blood pressure control and ED. Strengths of our study include the large sample size, community cohort, and completeness of follow-up. ConclusionAmong adults diagnosed with hypertension, tighter blood pressure control, as measured by average systolic blood pressure and deviation from the average, is associated with a lower incidence and a longer time to the development of ED.Hsiao W, Bertsch RA, Hung Y-Y, et al.

Clarifying the Relative Impacts of Vascular and Nerve Injury That Culminate in Erectile Dysfunction in a Pilot Study Using a Rat Model of Prostate Irradiation and a Thrombopoietin Mimetic

Radiation therapy (RT) offers an important and curative approach to treating prostate cancer, but it is associated with a high incidence of erectile dysfunction (ED). It is not clear whether the etiology of radiation-induced ED (RI-ED) is driven by RT-mediated injury to the vasculature, the nerves, or both. This pilot study sought to distinguish the effects of vascular and nerve injury in RI-ED by applying a vascular radioprotectant in a rat model of prostate RT. A single dose of the thrombopoietin mimetic (TPOm; RWJ-800088), previously shown to mitigate radiation-induced vascular injury, was administered 10minutes after single-fraction conformal prostate RT. Nine weeks after RT, rats were assessed for erectile and arterial function. Nerve markers were quantified with reverse transcriptase polymerase chain reaction. Immunofluorescent microscopy further characterized vascular effects of RT and TPOm. Sham animals and animals that received RT and TPOm showed significant arterial vasodilation in response to systemic hydralazine (24.1%±7.3% increase; P=.03 in paired t test). However, animals that received RT and vehicle were unable to mount a vasodilatory response (-7.4%±9.9% increase; P=.44 in paired t test). TPOm prevented RT-induced change in the penile artery cross-sectional area (P=.036), but it did not ameliorate cavernous nerve injury as evaluated by gene expression of neuronal injury markers. Despite significant structural and functional vascular protective effects and some trends for differences in nerve injury/recovery markers, TPOm did not prevent RI-ED at 9 weeks, as assessed by intracavernous pressure monitoring after cavernous nerve stimulation. These data suggest that vascular protection alone is not sufficient to prevent RI-ED and that cavernous nerve injury plays a key role in RI-ED. Further research is required to delineate the multifactorial nature of RI-ED and to determine if TPOm with modified dosing regimens can mitigate against nerve injury either through direct or vascular protective effects.

Conservative management and radical treatment in localised prostate cancer: A systematic review with meta-analysis and trial sequential analysis

Background: Several randomised control trials comparing conservative management (watchful waiting/observation/active monitoring) and radical treatments (radical prostatectomy/radiotherapy) for localised prostate cancer with at least more than 10 years of follow-up (median) have been published with conflicting findings. The primary aim of this study was to determine all-cause mortality and prostate cancer-related mortality between conservative management and radical treatment for localised prostate cancer. Methods: All randomised clinical trials were searched in MEDLINE, EMBASE, PubMed and CENTRAL from their inception until September 2018. Results: Four trials were eligible ( n = 3211) for inclusion in the data synthesis. In patients who had radical treatment, the incidence of all-cause mortality and prostate cancer-related mortality (three trials, 3069 patients) were reduced (with odds ratio, i.e. 95% confidence interval (CI)), of 1.37 (1.14–1.64), ρ &lt; 0.001, low quality of evidence and odd ratio (95% CI) of 1.74 (1.31–2.30), ρ &lt; 0.001, low quality of evidence, respectively). The radical treatment group was associated with reduced incidence of distant metastases, the odds ratio (95% CI) being 1.87 (1.48–2.36), ρ &lt; 0.001, low quality of evidence. However, patients who were randomised to radical treatment had a significantly higher incidence of erectile dysfunction (the odds ratio (95% CI) being 0.62 (0.39–0.98), ρ = 0.04, very low quality of evidence) and urinary incontinence (odds ratio (95% CI) of 0.42 (0.21–0.86), ρ = 0.02, very low quality of evidence). Conclusions: In summary, radical treatments reduce all-cause mortality, and prostate cancer-related and distant metastases, at the expense of higher incidence of erectile dysfunction and urinary incontinence. The general quality of evidence ranged from very low to low. Level of evidence: 1a PROSPERO Registration Number: CRD42017072687

Comparison of impact of monopolar versus bipolar resection of the prostate on erectile function in patients with benign hyperplasia of the prostate

Introduction and ObjectiveThe incidence of erectile dysfunction (ED) after TURP for BPH is still debated. Current study aims at comparing the impact of monopolar and bipolar TURP on the sexual function of male patients with LUTS, using the IIEF EF-domain score (questions 1–5, 15) and to identify statistical risk factors associated with development of post-operative ED. Patients and methodsBetween April 2014 and May 2015, 102 patients underwent TURP for symptomatic BPH. Sixty on underwent TURP by the monopolar technique and 41 by the bipolar technique. Patients were assessed on the day before the surgery by IIEF and followed up 3 and 6 months postoperatively, using the same scoring system. ResultsOn a 6 month follow up,13 patients (22.4%) in the monopolar group and 12 (30%) in the bipolar group, experienced clinical change in their EF score. Among risk factors studied, only diabetes, intraoperative capsular perforation and preoperative use of PDE5I had a statistically significant impact on the EF score.No statistically significant difference in IIEF score and EF domain score was observed between the patients who underwent TURP by the monopolar technique, compared to those patients in which the bipolar one was used; whether at three months (p value 0.33) or at six months (p value 0.397). ConclusionNo statistical difference could be detected between monopolar and bipolar TURP, regarding the risk of developing post-operative ED. However, a higher incidence of ED should be anticipated in patients with DM, intraoperative capsular perforation and preoperative use of PDE5I.

Erectile dysfunction is associated with subclinical carotid vascular disease in young men lacking widely-known risk factors.

This study aimed to gain insight into the underlying pathogenesis of erectile dysfunction in young men under the age of 40 years without widely-known risk factors. Compared with normal controls, patients with erectile dysfunction had increased carotid intima–media thickness, fasting levels of blood glucose and insulin, and homeostatic model assessment index, as well as lower flow-mediated vasodilation and testosterone levels (P < 0.05), though all of these values were within their respective normal range. Multivariate logistic regression analysis identified carotid intima–media thickness, flow-mediated vasodilation, insulin level, and homeostatic model assessment index as significant predictors of erectile dysfunction. Young men with flow-mediated vasodilation <10.65% were 11.645 times more likely to have erectile dysfunction, young men with carotid intima–media thickness >0.623 mm had a 4.16-fold, and young men with homeostatic model assessment index >1.614 had a 5.993-fold greater risk of having erectile dysfunction. In conclusions, in young men with normal results from general clinical screening, an increased carotid intima–media thickness and homeostatic model assessment index and reduced flow-mediated vasodilation were associated with a higher incidence of erectile dysfunction. Erectile dysfunction may appear before the detection of traditional cardiovascular risk factors and may be the earliest clinical sign of subclinical cardiovascular disease.

Prognostic Factors and Outcome of Management of Ischemic Priapism in Zaria, Nigeria.

Objectives:The objective of this study was to determine the nuances of management, prognostic factors, and outcome of ischemic priapism in patients seen at Ahmadu Bello University Teaching Hospital, Zaria, Nigeria.Patients and Methods:We retrospectively studied the case notes of all patients managed for ischemic priapism in the Ahmadu Bello University Teaching Hospital, Zaria, over a period of 10 years (2006–2015). The data extracted included patients’ age, occupation, duration of painful penile erection, and previous episodes. Addition information including precipitating factors, hemoglobin genotype, treatment, and complications was also retrieved. Data obtained were analyzed using SPSS version 20.Results:The records of a total of forty patients managed for priapism over the period under review were retrieved. Thirty-three (82.5%) of these patients had an operative intervention. The mean age was 23.7 years with a range of 8–53 years. Sixty percent of patients were young adults in their third decade of life. The minimum duration of erection at presentation was 18 h and a maximum period of 10 days with a mean of 105.5 h (4 days). Thirty-three patients (82.5%) had sickle cell anemia (HbSS). Erectile dysfunction (ED) accounted for 60% of all forms of postpriapism complications. Five patients (12.5%) had residual tumescence from fibrosis, and three patients had recurrence outside the immediate postoperative period. Duration of symptoms before surgical intervention, SSA and previous episodes were the most important prognostic factors.Conclusion:Priapism is a disease of the young, mostly sickle cell anemic patients. Late presentation remains the norm in our environment, hence a higher incidence of ED. The distal penile shunt is an effective means of achieving detumescence even with failed conservative management. Favorable outcome is highly dependent on the duration of erection and early intervention.

Importance of Different Grades of Abdominal Obesity on Testosterone Level, Erectile Dysfunction, and Clinical Coincidence.

The aim of the current study was to investigate the influence of different grades of abdominal obesity (AO) on the prevalence of testosterone deficiency syndrome (TDS), erectile dysfunction (ED), and metabolic syndrome (MetS). In a cross-sectional descriptive study, a total of 216 males underwent a complete urological, internal, and hormonal evaluation. Males were divided according to waist circumference into five groups: less than 94 cm (Grade [G] 0), 94 to 101 cm (G1), 102 to 109 cm (G2), 110 to 119 cm (G3), and more than 120 cm (G4). Incidence of ED, TDS, and MetS was compared in these groups and in participants without AO. Some degree of ED was identified in 74.7% of males with AO. In G1, there were 61% of males with ED, in G2 68%, in G3 83%, and in G4 87%. A strong correlation between testosterone (TST) level and AO was identified. Ninety-eight out of 198 (49.5%) males with AO and 1/18 (5.5%) males without AO had TDS. There were significant differences between individual groups. In the group of males with AO G4 (more than 120 cm), 87.1% had TDS. MetS was diagnosed in 105/198 (53.0%) males with AO, but in G4, 83.9% of males with AO had MetS. Males older than 40 years of age with AO have a higher incidence of ED, TDS, and MetS. Dividing males into five groups according to waist circumference seems to be reasonable. With growing AO, there were significantly more males with ED, TDS, and MetS.

Penile Fracture: Outcomes of Early Surgical Intervention

To report a series of penile fractures, describing preoperative evaluation, surgical repair, and long-term outcomes.Medical records from Northwestern Memorial Hospital and Oregon Health & Science University from 2002 to 2011 were reviewed. Clinical presentation, preoperative evaluation, time from injury, mechanism and site of injury, and presence of urethral injury were assessed. Outcomes including erectile dysfunction, penile curvature, and voiding symptoms were evaluated using International Prostate Symptom Score and International Index of Erectile Function scores.Twenty-nine patients with 30 separate episodes of penile fractures presenting to the emergency room were identified. Mean patient age was 43 ± 9.6 years. The time from presentation to the initiation of surgery was 5.5 ± 4.4 hours. Mechanism of injury was intercourse in 26 of 30 fractures with the remaining attributed to masturbation or "rolling over." Immediate surgical repair was offered to all patients. Twenty-seven patients underwent surgery. Urethral injury was noted in 5 of the 27. The site of fracture was at the proximal shaft in 11, mid shaft in 12, and distal shaft in 4 patients. The mean follow-up period was 14.3 ± 15.8 weeks. Nine patients reported new mild erectile dysfunction or penile curvature. One patient reported new irritative voiding symptoms.The most common mechanism of penile fracture was from sexual intercourse, and frequent concomitant urethral injuries were observed. The frequency of concomitant urethral injury was higher than in previous studies. Although we observed high incidence of erectile dysfunction or penile curvature with early surgical repair, we retain it as the favored approach.

Flexibility in Men's Sexual Practices in Response to Iatrogenic Erectile Dysfunction after Prostate Cancer Treatment.

IntroductionProstate cancer (PCa) treatments are associated with a high incidence of erectile dysfunction (ED). Interventions to help men with iatrogenic ED have largely focused on penile tumescence adequate for vaginal penetration. Less research has been undertaken on sex practices other than penile/vaginal intercourse.AimThe aim of this study was to explore forms of sexual practice engaged in by men following treatment for PCa. We focused in particular on anal intercourse (AI) as practiced by both nonheterosexual (i.e., gay-identified men and other men who have sex with men) and heterosexual men. We sought to determine how common AI was subsequent to PCa treatment and how flexible AI practitioners were in their modes (e.g., from insertive to receptive) when faced with iatrogenic ED.MethodsAn international online survey was conducted in 2010–2011 of men treated for PCa, where participants (N = 558) were asked explicitly about their sexual practices before and after PCa treatment.Main Outcome MeasuresThe outcome measures were the numbers and percentages of men who practiced AI before and after PCa treatment as well as the percentage who changed AI practice after PCa treatment.ResultsFive hundred twenty-six men (90 nonheterosexual men; 436 heterosexual men) answered questions on AI practices. A proportion of nonheterosexual (47%) and heterosexual men (7%) practiced AI following PCa treatment, and did so in all modes (insertive, receptive, and “versatile”). Many nonheterosexual men continued to be sexually active in the face of iatrogenic ED by shifting from the insertive to receptive modes. A few men, both heterosexual and nonheterosexual, adopted AI for the first time post-PCa treatment.ConclusionsFlexibility in sexual practice is possible for some men, both nonheterosexual and heterosexual, in the face of iatrogenic ED. Advising PCa patients of the possibilities of sexual strategies that include AI may help them in reestablishing a sex life that is not erection dependent.
