This report describes the color and pulsed Doppler US findings of penile Mondor's disease. The pulsed Doppler US findings of penile Mondor's disease have not been previously published, so we report here for the first time on the cavernosal arterial flow signal pattern of penile Mondor's disease. Penile Mondor's disease is rare disease that's characterized by thrombosis in the dorsal vein of the penis. The previous reports on penile Mondor's disease are concerned with the color Doppler US finding without the flow signals in this area, but these findings are insufficient to understand the hemodynamics in penile Mondor's disease. We report for the first time on a cavernosal artery flow signal pattern of low peak systolic velocity and high-resistance.

PURPOSE: Penile fracture is rare, but it is a urological emergency that always requires immediate attention. Moreover, penile fracture has been reported more frequently in recent years. It may have devastating physical, functional, and psychological consequences if not properly managed in time. MATERIALS AND METHODS: The objective of this study was to highlight the causes, clinical presentation, and outcomes of cases of penile fracture. This was a prospective observational study extending from November 2012 to November 2014. Each patient underwent a thorough clinical evaluation and received proper treatment. RESULTS: Twenty patients with penile fracture, aged 19 to 56 years (mean, 28 years) were evaluated in this study. Vaginal intercourse was the most common mechanism of injury. Most of the patients (95%) were diagnosed clinically with a proper history and clinical examination. Nineteen patients were treated surgically. The patients underwent six months of follow-up, and were evaluated with local examinations, questionnaires, and colour Doppler ultrasonography as necessary. CONCLUSIONS: Although penile fracture is an under-reported urological emergency, its incidence is increasing. It is usually diagnosed based on a clinical examination, but ultrasonography can be very helpful in diagnosis. Especially in cases where treatment is delayed, surgery is preferable to conservative management, because it is associated with better outcomes and fewer long-term complications.

PURPOSE: Ischemic priapism, a compartment syndrome, requires urgent treatment in order to nourish the corpora cavernosa. As the first step, aspiration of blood and irrigation of the cavernosal bodies is performed to prevent fibrotic activity and secure erectile capability. During aspiration, there are risks of cardiovascular side effects of adrenergic agonists. We aimed to evaluate a transient distal penile corporoglanular shunt technique in place of aspiration and irrigation techniques for treatment of early ischemic priapism. MATERIALS AND METHODS: A transient distal penile shunt was applied to 15 patients with early ischemic priapism between January 2011 and May 2012. Priapism duration, history, causes, pain, and any prior management of priapism were assessed in all patients. A complete blood count and penile Doppler ultrasonography were performed, which showed attenuated blood flow in the cavernosal artery. A sterile closed system blood collection set, which has two needles and tubing, was used for the transient distal penile shunt. RESULTS: Ten of 15 patients with early ischemic priapism were successfully treated with this transient shunt technique. No additional procedures were needed after the resolution of rigidity in the 10 successfully treated patients. CONCLUSIONS: The transient nature of this technique is an advantage over aspiration and irrigation in the treatment of early ischemic priapism. Our results indicate that the technique can be offered for patients with an ischemic priapism episode of no more than 7 hours.

Penile disease is one of the male urological diseases. Although the penis is a small organ, once the problem occurs, it often brings great trouble to the patient. Therefore, the accurate diagnosis of penile disease is particularly important. High-frequency ultrasonography, with its advantages of noninvasiveness, safety, low cost, easy operation and reproducibility, can clearly show the structure and blood flow of the penis and has a significant value in the diagnosis and follow-up of penile diseases such as vascular erectile dysfunction, priapism, penile injury, penile neoplastic and non neoplastic nodules. Meanwhile, the development of new technologies such as shear wave elastography (SWE) and contrast enhanced ultrasound (CEUS) has made up for the shortcomings of traditional ultrasound imaging, expanded the application of ultrasound in penile diseases, and improved the efficiency of ultrasound diagnosis of the diseases. This article focuses on the application value of ultrasound in erectile dysfunction, priapism, penile cavernous injury and penile tubercle, as well as the latest progress in such new technologies as SWE and CEUS applied to penile diseases.

PURPOSE: Smoking is a known risk factor for lung cancer, cardiovascular diseases, and atherosclerosis. The link between smoking and erectile dysfunction(ED) has been supported from in vitro studies, animal studies, and epidemiological evidence. We evaluated the effect of smoking on penile hemodynamics in ED. MATERIALS AND METHODS: Patients aged 40~80 years who visited our urological institute for ED were enrolled. We performed a standard ED evaluation that included medical history, physical examination, and measurements of serum glucose, testosterone, and prolactin. We excluded ED patients with abnormal androgen profiles and patients with ED risk factors other than smoking. A total of 108 ED patients entered the study, including 51 current smokers, 24 non-smokers, and 33 ex-smokers. All patients then underwent extensive evaluation, including nocturnal penile tumescence and rigidity(NPTR) monitoring with Rigiscan(R), and pharmacopenile Doppler ultrasonography for peak systolic velocity(PSV), and end diastolic velocity(EDV). RESULTS: The average ages of the current smokers, non-smokers, and ex-smokers were 55.7+/-4.6, 53.7+/-3.9, and 56.5+/-4.3 years, respectively(p=0.07). Of current smokers, 78% had abnormal NPTR testing, compared with 64% of non-smokers and 67% of ex-smokers(p=0.04; current vs non-smokers, p=0.04; current vs ex-smokers). The average PSV for current smokers, non-smokers, and ex-smokers was 26.8+/-3.2, 31.2+/-4.5, and 29.7+/-4.4 cm/s, respectively(p=0.06; current vs non-smokers, p=0.07; current vs ex-smokers). The average EDV for current smokers, non-smokers, and ex-smokers was 5.9+/-2.7, 4.4+/-1.6, and 4.2+/-1.5 cm/s, respectively(p=0.04; current vs non-smokers, p=0.03; current vs ex-smokers). In the currently-smoking patients, there was no significant correlation between NPTR, PSV, or EDV and the amount or duration of smoking. CONCLUSIONS: We concluded that dysfunction of penile veno-occlusive mechanism plays a substantial role in the development of ED in smokers.
