Función eréctil después de cistectomía con preservación neurovascular

ObjectivesTo study the utility of neurovascular preservation for postoperative erection in radical cystectomy.Materials and methodsRetrospective analysis of 44 cystectomies performed at our center between January 2006-December 2009 in men < 65 years. In 11 cases a neurovascular preservation was done. We analyzed age, BMI, indication for surgery, urinary diversion, use of i-PDE5 or alprostadil, and daytime and nighttime continence. Erection Hardness Score (EHS) was used to assess erectile function.ResultsSpontaneous postoperative erectile function in preservation group was 44,4% EHS 4, 33,3% EHS 3 and 22,3% EHS 1 (achieving EHS 3 or 4 with alprostadil). In the non preservation group, 4,5% achieved EHS 4 spontaneously. The other 95,5% had EHS 0 (4,5% achieved EHS 3 with tadalafil 20 mg and 9% with intracavernous injections). Variables age (P = .001) and nerve-sparing surgery (P < .001) were related to postoperative erectile function recovery. In the multivariate analysis, nerve-sparing surgery remained statisticaly significant.ConclusionsThe functional results in preserving cystectomy are promising. The preservation should be considered in young patients without erectile dysfunction.

Efficiency of intracavernosal alprostadil and oral clomiphene citrate combination treatment in penile vasculogenic erectile dysfunction patients accompanied by late-onset hypogonadism

In this study, the efficiency of intracavernosal alprostadil + oral clomiphene citrate (CC) treatment in late-onset hypogonadism (LOH) accompanied by penile vasculogenic erectile dysfunction (PVED) in patients irresponsive to phosphodiesterase type 5 inhibitor treatment was evaluated. A total of 31 patients with concurrent PVED and LOH were included in the study. The patients were given intracavernosal alprostadil (10–20 μg) and oral CC (50 mg) every day for 12 weeks. Before and after treatment, a 15-question International Index of Erectile Function (IIEF-15) questionnaire, Erection Hardness Score (EHS), Sexual Encounter Profile (SEP)2 and SEP3 levels were analysed, and follicle stimulating hormone (FSH), luteinising hormone (LH), total testosterone and prostate-specific antigen (PSA) levels were measured. In all, 41.9% of patients had pure arterial deficiency, 19.3% had pure venous deficiency, and 38.7% had arterial + venous (mixed) deficiency. A significant increase was detected in total testosterone, FSH, LH and PSA values after treatment when compared to values before treatment (p < .001, p < .001, p < .001 and p = .034 respectively). A significant recovery was observed in IIEF-15 subscores, EHS and SEP2-SEP3 results. In PVED patients accompanied by LOH, intracavernosal alprostadil and oral CC combination is an efficient, low cost, safely applicable and tolerable treatment.     

An assessment of patient-reported outcomes for men with erectile dysfunction: Pfizer's perspective

Patient-reported outcomes (PROs) for men with erectile dysfunction (ED) have blossomed in the published literature and at professional conferences. These outcomes have been central to study the science of ED itself and to evaluate efficacy of treatment for men with ED. In this review article we highlight and distinguish among seven key PROs: the International Index of Erectile Function, for sexual function including erectile function; the Sexual Health Inventory for Men (SHIM), for diagnosis of ED; the Quality of Erection Questionnaire, for satisfaction with quality of erections; the Erectile Dysfunction Inventory of Treatment Satisfaction, for personal evaluation of treatment received; the Self-Esteem And Relationship questionnaire, for emotional well-being; the Erection Hardness Score (EHS), for targeting erection hardness and the Sexual Experience Questionnaire, for erection (both function and quality), individual satisfaction and couples satisfaction. Depending on the purpose of the investigation, all seven PROs have merit for use in clinical trials and at least deserve consideration in clinical practice. The SHIM and the EHS, given their aims and brevity, deserve special consideration in clinical practice. As a unit these seven PROs complement and supplement each other. Which ones to choose in a particular undertaking depends on the objective or purpose of a given study. These PROs acknowledge that sexual dysfunction and its treatment have multiple dimensions. Each of these instruments represents a significant contribution to sexual medicine research and, when used judiciously and appropriately, can help to provide optimal patient care and management.     

The application of color Doppler flow imaging in the diagnosis and therapeutic effect evaluation of erectile dysfunction

We aim to investigate the correlations between hemodynamic parameters, penile rigidity grading, and the therapeutic effects of phosphodiesterase type 5 inhibitors using color Doppler flow imaging after intracavernosal injection in patients with erectile dysfunction. This study involved 164 patients. After intracavernosal injection with a mixture of papaverine (60 mg), prostaglandin E₁ (10 μg), and lidocaine (2%, 0.5–1 ml), the penile vessels were assessed using color Doppler flow imaging. Penile rigidity was classified based on the Erection Hardness Score system as Grades 4, 3, 2 or 1 (corresponding to Schramek Grades V to II). Then, the patients were given oral sildenafil (50–100 mg) and scored according to the International Index of Erectile Function (IIEF-5) questionnaire. The number of patients with penile rigidities of Schramek Grades II to V was 14, 18, 21, and 111, respectively. The IIEF-5 score was positively correlated with the refilling index of the penile cavernosal artery (r = 0.79, P < 0.05), the peak systolic velocity (r = 0.45, P < 0.05), and penile rigidity (r = 0.75, P < 0.05), and was negatively correlated with the end diastolic velocity (r = −0.74, P < 0.05). For patients with erectile dysfunction, both the IIEF-5 score after sildenafil administration, which is correlated with penile rigidity, and the hemodynamic parameters detected using color Doppler flow imaging may predict the effects of phosphodiesterase type 5 inhibitor treatment and could provide a reasonable model for the targeted-treatment of erectile dysfunction.     

Effect of low-intensity extracorporeal shockwave therapy on nocturnal penile tumescence and rigidity and penile haemodynamics

The study aims to evaluate the effect of low-intensity extracorporeal shockwave therapy (Li-ESWT) on nocturnal erection and penile haemodynamics. Patients with erectile dysfunction (ED) were enrolled from January 2018 to March 2019. Self-reported erectile symptoms, the International Index of Erectile Function-5 (IIEF-5) and Erection Hardness Scores (EHS), nocturnal penile tumescence and rigidity (NPTR) and cavernous duplex Doppler ultrasound (CDDU) were evaluated. NPTR and CDDU were evaluated by Rigiscan and vascular ultrasound system respectively. Comparisons of NPTR and CDDU parameters were performed before and after Li-ESWT (Renova, once a week, 4 weeks in total). A total of 35 cases (mean age 36.51 ± 11.47 years) were enrolled for analysis. The IIEF-5 (10.60 ± 5.99 vs. 15.13 ± 6.22, p = .003), EHS (p = .016) and self-reported erectile hardness (p = .014) were significantly improved after 1-month treatment. Nocturnal erection frequency (p = .010), duration of total erection (p = .017), duration of erectile rigidity ≥60% at penile tip and base (p = .014 and p = .002) and the best erectile rigidity at penile tip and base (p = .012 and p = .005) improved significantly after treatment. However, no CDDU parameters improved after Li-ESWT (all p > .05). Li-ESWT can effectively improve subjective erectile function and nocturnal erection in ED patients. Large sample and well-designed studies need to be developed for supporting the current findings.

Significance of erection hardness score as a diagnostic tool to assess erectile function recovery in Japanese men after robot-assisted radical prostatectomy

The objective of this study was to characterize time-dependent recovery of erectile function in Japanese patients following robot-assisted radical prostatectomy (RARP) using the erection hardness score (EHS). This study prospectively included 170 Japanese patients with localized prostate cancer (PC) undergoing RARP without neoadjuvant hormonal therapy. The erectile function of each patient was assessed based on the International Index of Erectile Function-5 (IIEF-5) and EHS at the baseline and on every visit to an outpatient clinic after RARP. In this series, potency was defined as the ability to have an erection sufficient for intercourse, corresponding to EHS ≥3, while patients with EHS ≥2 were regarded as those with erectile function. Of these 170 patients, 20 and 75 underwent bilateral and unilateral nerve-sparing procedures, respectively; however, non-nerve-sparing procedures were performed in the remaining 75. A proportional increase in the IIEF-5 score according to EHS was noted at 24 months after RARP. At 6, 12 and 24 months after RARP, the recovery rates of erectile function were 11.9, 21.7 and 35.8 %, respectively, while those of potency were 3.8, 9.8 and 13.7 %, respectively. Of several factors examined, the age, preoperative IIEF-5 score and nerve-sparing procedure were identified as independent predictors of erectile function recovery. These findings suggest that favorable erectile function recovery could not be achieved in Japanese PC patients even after the introduction of RARP; therefore, it might be preferable for such a cohort to use EHS rather than IIEF-5 as an assessment tool for the postoperative recovery of erectile function.
