Effect of sildenafil on nocturnal erections of potent men

We try to evaluate the effect of sildenafil on nocturnal penile erections of potent men. We recruited 22 potent men (eight medical students and 14 urology residents) 23-29 years old into the study. A disorder-free medical and sexual history and normal erectile functions were the only inclusion criteria. All subjects completed three sessions of consecutive nights using the RigiScan Plus device. After a first night of adaptation, night 2 recordings were their baseline values whereas they received sildenafil 100 mg on night 3. We observed statistically significant improvement with regard to those NPT parameters at the nights with sildenafil: number of erectile episodes; duration of tip rigidity >60%, RAU tip, RAU base and TAU tip (P<0.005). Although the duration of erectile episodes (min) and TAU base were greater during the sildenafil night, these did not reach statistical significance. In conclusion, our study showed that sildenafil can improve nocturnal erectile quality not only in patients with erectile dysfunction as previously published but also in potent males.     

Nocturnal electrobioimpedance volumetric assessment in diabetic men with erectile dysfunction before and after tadalafil intake

Nocturnal electrobioimpedance volumetric assessment (NEVA) is a procedure that can measure penile volume changes together with the number and duration of nocturnal erectile events. This study was conducted to evaluate the different NEVA patterns in diabetic patients with erectile dysfunction (ED), and demonstrate the extent to which tadalafil may affect the characteristics of nocturnal penile erections in these patients. Therefore, 38 patients with noninsulin-dependent diabetes and ED participated in this study. They were assessed with history intake including evaluation by the abridged five-item version of International Index of Erectile Function, clinical and psychiatric assessment and NEVA for three consecutive nights where placebo was given on the second night and tadalafil on the third night. In all, 14 potent males were taken as a control group. Data were analyzed using t-test. Results showed normal patterns in only six (16%) patients (central organic group), while abnormal patterns were observed in the remaining 32 (84%) patients (peripheral organic group). These abnormal patterns showed significant decrease in both the number (P=0.0001) and duration (P=0.03) of erectile events compared to those of controls. The percentage of penile blood volume change over baseline also decreased significantly (P=0.0002) relative to controls. Veno-occlusive dysfunction was the main pathology (23 patients, 72%) as suggested by NEVA. Tadalafil did not significantly change basal nocturnal penile tumescence results in either the central organic or control groups, but it did so significantly in the peripheral organic group (P=0.02 for duration change and P=0.01 for % blood volume change). In conclusion, NEVA may suggest some evidence about the pathophysiology of an underlying vasculogenic cause, thus directing towards the next specific step needed for a precise diagnosis. Tadalafil improves nocturnal erections in diabetic patients with peripheral but not central organic impotence.     

夜间生物电阻抗容积测定对勃起功能障碍的诊断

Recovery of sexual function after nerve-sparing radical prostatectomy or cystectomy

BACKGROUND: The recovery of sexual function (erectile function and frequency of sexual intercourse) over time after nerve-sparing radical prostatectomy or cystoprostatectomy was evaluated. METHODS: Forty-nine consecutive patients with clinically localized prostate cancer and muscle-invasive bladder cancer were treated with radical prostatectomy and radical cystoprostatectomy with a nerve-sparing procedure. Erectile function was evaluated by the circumferential change of the penis during nocturnal penile tumescence (NPT value) with an erectometer before and after surgery. Erectile function and the frequency of sexual intercourse were also evaluated with a self-administered questionnaire before and after surgery. Multivariate analysis by Cox's proportional hazards model was used to evaluate the factor(s) that affected the recovery of erectile function and sexual intercourse. RESULTS: The recovery rates of erectile function were 49% at 3 years and 79% at 5 years. For recovery of sexual intercourse the rates were 36% at 3 years and 57% at 5 years. Multivariate analysis revealed that the preoperative NPT value was the only independent factor which significantly affected the recovery of erectile function. The age at surgery was a significant factor for recovery of sexual intercourse. CONCLUSION: Nerve-sparing operations can often, but not always, provide preservation or recovery of erectile function for patients who receive radical prostatectomy or cystoprostatectomy. Recovery of erectile function depends upon the preoperative NPT value and recovery of sexual intercourse depends upon the age of the patient.     

Comparative evaluation of impotence with vibration and nocturnal monitoring

Vibratory stimuli were used for diagnostic evaluation of 130 impotent patients. The stimuli were applied to the glans penis, and erectile response was measured and displayed on a recorder. The erectile response to vibration was compared with nocturnal penile tumescence (NPT) monitoring and to artificially produced full erection. At the present time vibratory stimuli do not represent an alternative diagnostic method to NPT. However, the two methods are complementary. Erectile activity during vibration was detected in 43 of 130 patients. For these 43 patients further evaluation with NPT monitoring would not be necessary. Because vibration evaluation is performed as an outpatient procedure, it can contribute to a significant cost reduction in the evaluation of impotent patients.     

夜间阴茎勃起测定在性功能障碍诊断中的应用
