Sixty eight impotent men underwent corpora cavernosography and corpora cavernosal pressure measurements during saline infusion. Nineteen of the men had internal pudendal arteriograms. Correlation between the cavernosograms and saline infusion induced pressure measurements was "good" in 56/66(84%), "approximate" in 5/66(8%) and there was no correlation in 5/66(8%). Two patients were excluded for technical reasons. The spread of results and the good correlation of the two tests speaks for the accuracy of the method. It was of value in diagnosis and will be of paramount importance if veno occlusive surgery becomes a reliable method of treatment.

[RigiScan monitoring assists tadalafil medication in the treatment of penile ED].

Objective: To investigate the application value of RigiScan monitoring in assisting tadalafil medication.
Methods: This self-control study included 89 ED patients (IIEF-5 < 21) treated in our hospital from August 2019 to July 2020. The patients underwent audiovisual sexual stimulation (AVSS), nocturnal penile tumescence and rigidity (NPTR) test, scoring on the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder 7-Item Scale (GAD-7), blood routine test, blood biochemical analysis, and hormone secretion examination, which confirmed 21 cases of psychogenic, 28 cases of organic and 40 cases of mixed ED.

Department of General and Emergency Radiology, "Antonio Cardarelli" Hospital, 80131 Naples, Italy.
Erectile dysfunction caused by venous leakage is a vascular disease in which blood fails to accumulate in the corpora cavernosa due to the abrupt drainage of blood from the penis secondary to an abnormal venous network that affects 1 to 2% of men under 25 years old and about 10 to 20% over 60 years old, who do not raise a sufficient erection for penetrative sex. The study of the venous leak and its characterization in young patients with erectile dysfunction represent a diagnostic challenge, and imaging remains the best way to diagnose this condition. In the article, it is described the methods of execution and the diagnostic role of the cavernous MRI in the study of vasogenic erectile dysfunction from the venous leak, proposing it as a good alternative to the cavernous CT, considering the satisfactory results in terms of diagnostic interpretation, the absence of ionizing radiation, the higher soft tissue resolution of the imaging method and the lower administration of contrast agent.

Background: Clinical assessment of Peyronie disease (PD) is unreliable and difficult to reproduce.

Methods: Men were placed in the Philips IQon Spectral CT scanner (Phillips, Cambridge, MA, USA) in the supine position.
The venous drainage of the corpora cavernosa in the human penis.

Objective: To study the drainage proportions from the corpora cavernosa in defrosted human cadavers, as the veins related to penile erection were recently depicted to comprise the deep dorsal vein (DDV), a pair of cavernous veins (CVs) and two pairs of para-arterial veins (PAVs), as opposed to a single DDV between Buck's fascia and the tunica albuginea of the human penis.
Materials And Methods: With no formalin fixation, 10 defrosted male human cadavers were used for this study. After injecting a 10% solution of colloid, and with the intracavernous pressure (ICP) fixed at 90 mmHg, the perfusion rate was recorded before and after the DDV, CVs and PAVs were removed, respectively.

The human erectile mechanism is an intricate interplay of hormonal, vascular, neurological, sinusoidal, pharmacological, and psychological factors. However, the relative influence of each respective component remains somewhat unclear, and merits further study. We investigated the role of venous outflow in an attempt to isolate the key determinant of erectile function.
