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.

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 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.

To clarify the correlation between erotic and nocturnal erection and evaluate their diagnostic efficacy in impotence, a comparative study was done with audiovisual stimulation penogram (AVS-Penogram) and nocturnal penile erection monitoring (NPEM: RigiScan) in two hundred twenty two impotent patients. The compatibility ratios of the audiovisual stimulation penogram and nocturnal penile erection monitoring were 74.2% in Type I (normal findings) and 66.6% in Type IIA penogram (unresponsive type). The ratio of type IIB (fluctuation type) was 37.9%. much lower compared to that of Type I. Based on the final diagnosis, audiovisua1 stimulation penogram-only had high compatibility ratio with psychogenic origin for Type I (77.7%) and with organic impotence for Type IIA (80%). Moreover combined audiovisual stimulation penogram and nocturnal penile erection monitoring had higher compatibility ratio (86.2%) than that of audiovisual stimulation penogram only analysis (77.7%) with psychogenic impotence. Therefore, we suggest that audiovisual stimulation penogram is an accurate method in Type I and Type IIA. Furthermore combined interpretation of audiovisual stimulation penogram and nocturnal penile erection monitoring may produce more precise diagnosis, especially in psychogenic impotence.

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.

This study was conducted in order to investigate the clinical significance of nocturnal penile tumescence recording with stamps. The results were as follows; 1. In the study of 33 normal potent men, 96 stamp tests were undertaken. Among them, stamp breakage occurred in 62 trials (64.6%) and in remaining 34 trials (35.4%) stamp breakage failed to occur. 2. In 30 (90.0%) of the 33 normal potent cases, showed one or more incidence of stamp breakage and was considered as a positive response and in the remaining 3 cases (9.1%) showed no stamp breakage at all in a three consecutive trials. 3. In 8 patients complaining impotence after urethral injury, showed no breakage of stamp at all in a consecutive 42 trials (100% negative response).

PURPOSE: Intracavernosal self injection therapy is now being widely used to treat patients with erectile dysfunction. However, there is a large number of patients who give up the self injection program due to the fear of injection. Therefore, less invasive route of drug administration is highly recommended. We investigated the efficacy of intraurethral instillation of Prostaglandin El (PGE1 ) solution in the patients who showed full erection with intracavernosal injection of PGE1. MATERIALS AND METHODS: Twenty-nine impotent patients who showed full erection with intracavernosal injection of PGE1 were included in this study. We estimated the grades and durations of the penile erection after intraurethral instillation of PGE1 RESULTS: Sixteen out of 29 patients(55.2%) showed full erection with intraurethral instillation. Two patients(6.9%) showed urethral pain which disappeared within 24 hours. But there was no systemic side effect CONCLUSIONS: Intraurethral instillation of PGE1 appears to be safe, well tolerated, and less invasive treatment modality Thus it can be selected as an alternative treatment of impotence in selected cases.
