PURPOSE We assessed the morphodynamic features of cavernous arteries and helicine arterioles by power Doppler sonography in vasculogenic and nonvasculogenic impotent men. MATERIALS AND METHODS A total of 40 impotent patients with and without definite vascular risk factors were studied by penile power Doppler sonography. The test was performed during(More)
In the present study venous plasma concentrations of testosterone (T), nitric oxide (NO) and endothelin 1-2 (ET1-2) in the flaccid penis and brachial blood were measured in men with psychogenic impotence. T and NO were significantly lower in the penile venous blood, while ET1-2 showed no statistical difference. These data support the hypothesis of(More)
INTRODUCTION In the era of orally active agents, dynamic penile color-duplex ultrasound (D-PCDU) is not considered a necessary first screening for all patients with erectile dysfunction (ED). Various parameters, such as peak systolic flow velocity, end diastolic velocity, resistance index, acceleration time, and degree of arterial dilatation, have been(More)
The firm refusal of blood transfusion treatment by Jehovah's Witnesses has always caused some discomfort to physicians. Two fundamental principles contained in the constitution of our own and other democratic countries specifically dictate that human rights are to be respected. No one may be forced to undergo any particular health treatment, save under the(More)
OBJECTIVE The purpose of this study, that examined healthy adult subjects and nephropatic patients, was to detect some relations between kidney's sonographic dimensions and renal function, expressed by creatinine clearance to evaluate more significant and useful sonographic parameters for the follow-up of nephropathies. SUBJECTS AND METHODS Age, sex, body(More)
Thrombotic microangiopathy, including the two related syndromes thrombotic thrombocytopenic purpura and hemolytic-uremic syndrome, is a rare and severe multisystem disorder, due to widespread deposition of intravascular microthrombi consisting mainly of platelets, with subsequent consumption thrombocytopenia, microangiopathic hemolytic anemia, renal(More)
Hemangioma is an extremely frequent tumor, accounting for 7% of all benign neoplasms. In contrast, hemangioma arising in blood vessels is rare and should be differentiated from other neoplasms of vascular origin, such as hemangioendothelioma, hemangiopericytoma, hemangiosarcoma, and leiomyosarcoma. The case we report has the peculiarity of occurring as a(More)
Three-dimensional ultrasound has already been employed to improve detection and characterization of the masses in various organs. The system can also be expected to improve qualitative evaluation of vessel pathology. Three-dimensional ultrasound could offer an additional contribution even in Andrology, in at least three fields: in the best evaluation of the(More)
The pelvic congestion syndrome has been widely studied in the female sex, while there are not many publications on the male equivalent. Prostatitis represent the most frequent affections of the genito-urinary male tract that require the urologic consult, but in the majority of the cases the etiology of such affections remains unknown. Some forms of(More)
