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 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 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.

This study is to compare the diagnostic usefulness and relationships between AVS penogram. Snap gauge test, and NPT monitoring in impotent patients confirmed using multidisciplinary diagnostic approach at the Department of Urology, Yonsei University College of Medicine from December 1986 to June 1987. Following results were obtained. 1. Among 24 cases of Group I(AVS penogram) 20 cases(83.3%) were psychogenic impotence, where 15 cases(75%) revealed sufficient penile rigidity on the Snap gauge test. 4 cases(16.7%) of group I were organic impotence, which revealed incomplete penile rigidity on the Snap gauge test. Among 45 cases of Group II-B(AVS Penogram) 34 cases(75.6%) were psychogenic impotence, where 28 cases(82.4%) showed sufficient penile rigidity on the Snap gauge test. 10 cases(24.4%) of Group II-B were organic impotence, which showed incomplete penile rigidity on the Snap gauge test. Among 17 cases of Group II-A and II-C 5 cases were psychogenic impotence, all of which revealed sufficient penile rigidity on the Snap gauge test. >From above results, the AVS Penogram is not a confirmative method, but using AVS Penogram and the Snap gauge test simultaneously will give useful information differentiating organic impotence and psychogenic impotence. 2. In comparison of AVS penogram and NPT monitoring, among 20 cases 7 cases of erectile curve showed similar shape, but the precise mechanism of each penile erection is not yet certain, more study is needed in the near future.

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.
