Background: Priapism has been linked to many commonly prescribed medications, as well as recreational drugs and toxins. Although the incidence of priapism as a result of medication is small, the increasing use of antidepressants, antipsychotics, and recreational drugs may lead to more cases of pharmacologically-induced priapism in the future.

Aim: To provide a comprehensive, up-to-date review of the most common causes of pharmacologically induced priapism and discuss incidence, pathophysiology, and basic management strategies. Read More

Priapism, a persistent erection of the penis which has no association with sexual activity and lasts longer than four hours, is a urologic emergency. It can be classified into ischemic, nonischemic, and stuttering categories. The pathophysiology of stuttering priapism is not well understood; however, the dysregulation of nitric oxide and phosophodiesterase-5 (PDE5) has been put forward as a possible mechanism. Read More

Priapism is a genitourinary emergency that demands a thorough, time-sensitive evaluation. There are 3 types of priapism: ischemic, nonischemic, and recurrent ischemic priapism; ischemic priapism accounts for 95% of cases. Ischemic priapism must be treated within 4 to 6 hours to minimize morbidity, including impotence. Read More

Background: Recurrent priapism secondary to sickle cell trait in an African-American male has been reported in the literature. A common treatment for these low-flow priapism cases is aspiration and injection of the corpus cavernosum with a sympathomimetic agent. We report a rare complication not described previously in the literature of ST-elevation myocardial infarction (STEMI) and cardiogenic shock in a 29-year-old male with sickle cell trait undergoing a routine detumescence procedure.

Priapism is characterized by involuntary persistent penile erection after or independent of sexual stimulation. The diagnostic clarification, including patient history, physical findings, duplex ultrasonography and analysis of blood gases is decisive for the underlying pathophysiology and the appropriate therapeutic procedure. Non-hypoxic and non-acidotic blood gas parameters enable a conservative approach, hypoxic, hypercarbic and acidotic parameters may lead to fibrosis of the corpora cavernosa and, in turn, to a loss of penile function.

Normal fertility is dependent on intravaginal delivery of semen through ejaculation. This process is highly dependent on an intact ejaculatory reflex arc, which can be disrupted through any type of trauma or disease causing damage to the CNS and/or peripheral nerves. Neurogenic anejaculation is most commonly associated with spinal cord injury. Read More

Introduction: Collagenase clostridium histolyticum (CCH) is an Food and Drug Administration-approved intralesional injection for treatment of Peyronie's disease (PD) that has been shown to reduce penile curvature deformity and PD symptom bother in phase 2b and phase 3 placebo-controlled clinical trials. For some patients, nonsurgical treatment with CCH may not sufficiently improve penile curvature, and surgical correction may be pursued following CCH therapy.

Aim: This study aims to examine intraoperative and postsurgical outcomes of surgical correction of persistent penile curvature in patients with PD who had previously received CCH. Read More

Penile color Doppler sonography is a valuable method for evaluating erectile dysfunction. However, there are some concerns about the safety of this method due to the intracorporeal pharmacological injection, which may cause priapism as a complication, resulting in penile fibrosis. To evaluate the actual incidence of papaverine-induced priapism in patients with erectile dysfunction (ED) who underwent penile colour Doppler sonography and to determine the safety of this diagnostic tool, a retrospective study was conducted using the database of our institution.
