ABSTRACT

PURPOSE: In patients with erectile dysfunction, it is important to differentiate psychogenic from organic causes. Penile Doppler ultrasonography is a relatively inexpensive and minimally invasive tool for this purpose. This study was conducted to evaluate the causes of erectile dysfunction in an adult male population, using penile Doppler ultrasonography. MATERIALS AND METHODS: A retrospective study was conducted in a single center. All patients who presented with complaints of erectile dysfunction and underwent penile Doppler ultrasonography between July 2014 and June 2016 were included in this study. All examinations were performed using GE Voluson S6 and GE Logiq P5 devices. Following baseline scans, an intracavernosal injection of 20 µg of prostaglandin E1 was given. Peak systolic and end diastolic velocities were measured in each cavernosal artery. Patients with a peak systolic velocity of 5 cm/s was considered to indicate venous incompetence. RESULTS: Out of 97 patients (mean age, 37.09±11.59 years; range, 19~69 years), 50 patients (51.5%) had normal findings, 24 patients (24.7%) had arterial insufficiency, 15 patients (15.5%) had a venous leak, and 8 patients (8.2%) patients had arterial insufficiency with a venous leak. Psychogenic erectile dysfunction was significantly higher among patients aged ≤40 years, while arterial insufficiency with or without a venous leak was significantly higher among patients aged >40 years (p=0.022). CONCLUSIONS: A majority of the studied individuals demonstrated no organic cause of erectile dysfunction, thus confirming a high prevalence of the psychogenic etiology, particularly in relatively young individuals.

ABSTRACT

Purpose: The proposal of this study was to determine the prevalence and the associated factors of erectile dysfunction (ED) among hemodialysis (HD) patients. Materials and Methods: This was a cross-sectional study based on data collected from HD male patients. Clinical, demographic and laboratory data of all patients were collected in three HD clinics from December 2010 to June 2011. Patients answered questions of erectile function domain from International Index of Erectile Function. Data were evaluated by descriptive analysis and by univariate (ULRA) and multivariate logistic regression analysis (MLRA). Results: Three hundred and five patients participated of the study. The prevalence of ED was 68.19%. ED was associated with diabetes (DM), benign prostatic hyperplasia, glomerulonephritis as cause of chronic renal failure (CRF), smoking habits, lower creatinine levels (ULRA), use of calcium channel blocker (MLRA), aging, lower education level, alcohol consumption, DM (as cause of CRF) and coronary insufficiency (ULRA and MLRA). Conclusions: ED was highly prevalent in the HD men. It was independently associated with aging, current use of alcohol, long alcohol use (even for those who do not drink more), lower education level, diabetes as cause of CRF, coronary insufficiency and use of channel blockers calcium. .

ABSTRACT

PURPOSE: The mean platelet volume (MPV) is a marker of the platelet activity and is reported to increase in vascular diseases. We aimed to investigate the association between MPV and vasculogenic erectile dysfunction (ED). MATERIALS AND METHODS: MPV and platelet (PLT) levels were measured in 50 cases of ED and 40 healthy controls. The diagnosis of vasculogenic ED was based on a detailed sexual history, physical examination, laboratory assessment, and color Doppler ultrasonography. The results are given as mean+/-standard deviation of the mean. RESULTS: The mean ages of the patient and the control groups were 53.70+/-12.39 years (range 24~77 years) and 53.85+/-9.5 years (range 30~73 years), respectively (p=0.947). The MPV and PLT values were significantly higher in the patients with ED than those of the controls (7.49+/-1.4), (6.85+/-1.2), (262.97+/-68), (252.89+/-82) respectively, p0.05), and there was no correlation between MPV and either age of patients (p=0.905) or duration of ED (p=0.583). CONCLUSIONS: The platelet count and MPV was detected to be increased in patients with vasculogenic ED. This finding suggests a role for platelets in the pathogenesis of vascular complications and that the MPV would be useful in monitoring disease progression.
