“…According to this technique, penile venous leak drainage can be divided into three groups: superficial veins, intermediate veins, and deep veins [40,41]. Hence, CT cavernosography not only is beneficial in terms of diagnosing a venous leak but is also useful for patient selection for either surgical or endovascular management.…”

Erectile dysfunction (ED) is a big issue in various populations with up to 30% of young men suffering from this condition. Unfortunately, treatment schemes are currently mainly focused on elderly patients with chronic disorders. In younger patients, ED is more a vascular problem, which affects the storage capacity of the penis. The impact of penile blood supply on erectile function was recognized some 500 years ago. At the turn of the twentieth century, the first results of penile venous ligation were published. Simple isolated ligation of the deep dorsal vein in humans for ED due to venous leak is currently not recommended, due to some reported low long-term success rates. This was, as shown in several literature reports, obviously due to insufficient technical possibilities. Technical development in imaging and vascular and endovascular treatment have dramatically evolved our understanding of this underlying condition in the past 20 years and turned this disease into a long-term treatable condition. The current state-of-the-art work-up of the underlying condition, using the newest imaging technologies with color Doppler ultrasound and CT scan with additional three-dimensional reconstruction, is to show the surgeon exactly the points to focus on. Additionally, a so-called corporo-venous insufficiency can be recognized as a mainly combined condition, affecting peripheral and more proximal drainage pathways at the same time.

“…CT-cavernosography is performed following intracavernosal injection of 20 μg prostaglandin E 1 . Thirty min post-injection a 7-G needle is inserted at the dorsal side of the corpora cavernosum and injection of 30–60 ml of 30% saline-diluted non-ionic iodinated contrast medium (320 mg ml −1 ) is performed with an infusion velocity of 6–180 ml min −1 ( 15 ). Recommended CT parameters are as follows: 64 × 0.625 mm collimation, gantry rotation time 0.75 s, time resolution 30 ms, pitch factor 0.984.…”

Erectile dysfunction is a defined as recurring inability to achieve and maintain satisfactory erection for sexual intercourse associated with relevant life impairment. The underlying etiologies may be manifold and complex. Currently, vascular etiologies are highly prevalent especially amongst elderly men. Of special interest, especially venogenic causes are of increasing relevance. Therapeutic options comprise risk factor modification, pharmacotherapy, surgical treatment, and endovascular treatment. Especially endovascular treatment options have recently increased in popularity including transcatheter embolization procedures for veno-occlusive dysfunction.

The prevalence of erectile dysfunction (ED) among men over 50 years is 31-51 %. By 2025, the prevalence of ED is expected to increase to 322 million men worldwide. In Russia, according to academician D.Yu. Pushkar', ED suffers up to 89.9 %.In this regard, it seems very important to establish the causes of this condition. The purpose of this review is to assess the current state of the literature on the issue of risk factors leading to or associated with the development of ED.The presented works show that well-known factors play a role in the occurrence of ED: unfavorable environmental conditions, harmful lifestyle factors, chronic intoxication, obesity, genetic predisposition, deficiency of sex hormones and vitamins, diseases of the cardiovascular system, prostate and urethra, as well as drugs for their treatment. Also, new indicators in laboratory and instrumental studies that change with ED are considered.Among the well-known data, there are also some very original works devoted to this topic. The relationship between ED and reproductive disorders, psoriasis, periodontitis, human immunodeficiency virus infection and some drugs use is now being investigated, which is presented in this review.

Computed tomography cavernosography combined with volume rendering to observe venous leakage in young patients with erectile dysfunction

Abstract: A modified evaluation method was used in this study to monitor the intracavernous pressure during examination. New classifications of the deep dorsal vein, prostatic venous plexus and crural vein are described in this study.
