Priapism has been classified as primary (idiopathic)and secondary according to etiology. Hemodynamically, it can be separated into two distinct types: low-flow (ischemic) and high flow (non-ischemic). In the latter type, the most common cause is blunt genital trauma, and selective cavernosal artery embolization has been the most effective therapeutic method. Two cases of high-flow arterial priapism are presented. Both cases were post-traumatic and were managed with selective cavernosal artery embolization, with excellent return of premorbid levels of erectile function.

Priapism is an uncommon condition of prolonged painful penile erection, and no sexual excitement or desire is present. The therapeutic goal in priapism is to restore normal circulation and blood flow in the erectile tissue of corporacavernosa. In recent years medical treatment is unsuccessful and it should be treated as a surgical emergency. Here we report one case of priapism with review of related recent references.

Updates on the use of vardenafil (Levitra) in the treatment of erection disorders including: specific inhibition with PDE5, treatment efficacy, pharmacokinetics, tolerance level, interaction, contraindication, cautions especially for people with cardiovascular diseases or penis surgery deformation, dosage and use. Except for above contraindication and cautions, vardenafil can be considered as first choice for men with erection disorders in accordance with PDE5 inhibition treatment

Priapism is defined as having prolonged (more than 6 h), and usually painful penile erection that occurs without a sexual desire or arousal. Only a very few priapism cases caused by ziprasidone are reported in the literature. In this case report we aimed to present a prolonged penile erection due to use of ziprasidone.

Penile erection is either sexual stimulating erection or nocturnal erection. The difference of precise mechanism between the two types is not clarified yet. In order to evaluate nocturnal erection, we used the Rigiscan which could simultaneously record nocturnal penile tumescence and rigidity. And sexual stimulating erection was evaluated by Audiovisual Stimulating Penogram which was introduced by Choi and Kim in 1987. The following results were obtained. The compatibility ratio of 16 normal sexual stimulating erection to nocturnal erection test was 56%, while that of 35 cases of abnormal sexual stimulating erection was 51% . The compatibility ratios of the group IIA and group IIC were 80% and 78%, respectively, revealing high percentage of concordance between the two types of erection. On the other hand, the compatibility ratio of group IIB was low(33%). From the results presented here, it can be concluded that the AVS-Penogram is useful for the screening test and to obtain more useful information, evaluation of the nocturnal erection using Rigiscan is necessary.

Continuous and simultaneous recording of nocturnal penile rigidity and tumescence is preferred than measuring tumescence alone to define the features of nocturnal penile erection and differentiate psychogenic from organic impotence. Rigiscan is suitable for this purpose. Authors studied to define the features of nocturnal penile erection by rigiscan in 24 normal Koreans and 18 patients with erectile dysfunction. The results were as follows : 1. In normal group, the number of normal erection was 4.2+/-0.9 times per night, duration was 21.1+/-7.4 minutes at tip and 26.3+/-9.8 minutes at base, tumescence change was 1.81+/-0.51 cm at tip and 2.23+/-0.72 cm at base, rigidity was 55.7+/-19.6 per cent at tip and 66.3+/-12.0 per cent at base. Maximal duration was 34.2+/-14.9 minutes at tip and 39.0+/-15.1 minutes at base, maximal tumescence change was 2.28+/-0.83 cm at tip and 2.64+/-0.78 cm at base, maximal rigidity was 65.4+/-11.8 per cent at tip and 75.8+/-12.5 per cent at base. The higher the age, the shorter the duration and number of events were(p<0.05). 2. In patient group, normal rigigram showed in 6 patients(3 of psychogenic, 3 of posterior urethral injury). Event and duration were shorter than normal group(p<0.05). The findings of flat trace or abnormal erection provide valuable information to screen the organic impotence.

Priapism is a pathologic state of persistent penile erection in the absence of sexual stimulation. Low flow priapism is more common, which is caused by a venous outflow obstruction. However, high flow priapism is rare, and is caused by uncontrolled arterial flow into penis following perineal or penile blunt injuries. We report a case of high flow priapism secondary to the treatment of low flow priapism.
