Review
High-frequency ultrasound is the imaging modality of choice for evaluating penile pathology because of its easy access, low cost, and patient tolerance ( The Penis, Diagnostic Ultrasound, second edtion . Boca Raton: CRC Press; 2007:957-978). This pictorial review will illustrate the sonographic features of emergent and nonemergent penile conditions such as penile fracture, spongial tear, urethral injury, various types of priapism, erectile dysfunction, penile abscess, and Mondor disease.

Review
BACKGROUND
Priapism is a rare condition characterized by persistent erection of the penis that lasts more than 4 hours in the absence of sexual stimulation and is associated with significant morbidity and complications, including erectile dysfunction and penile fibrosis. Surgical management of priapism can be extremely challenging. We herein provide a comprehensive review that aims to evaluate the role of penile prosthesis (PP) implantation in the management of priapism.
METHODS
A systematic literature search was performed using the following databases: PubMed, Embase, and Scopus to identify studies that evaluated the effectiveness of PP implantation in treating priapism and the long-term complications, outcomes, and patients' satisfaction rate.
RESULTS
Out of 717 English-language studies published between 2002 and 2022, 17 were chosen for this review. Majority of patients had a malleable PP (MPP) implant, either early or delayed after the priapism episode. Early placement (EP) of PP is widely defined between studies ranging from less than 72 hours, within 1 week, and within 3 weeks. Most common causes of priapism were sickle cell anemia (SCA), medication-induced, and idiopathic. Studies show a higher satisfaction rate ranging between 80% and 100%, with sexual intercourse achievement ranging between 64.2% and 100%. Based on the GRADE system, included studies rated as very low quality of evidence. Commonly reported complications that arise after PP procedures, include device infection, erosion, curvature, and mechanical malfunction, such as auto-inflation.
CONCLUSIONS
PP can be an effective treatment option for priapism, particularly in cases of ischemic priapism lasting more than 36 hours or recurrent priapism that is medically refractory. However, due to the very low quality of evidence, larger, well-designed studies are warranted where long-term outcomes, patients' satisfaction, and complications following priapism-related PP implantation are measured as endpoints.

Management of Priapism: Results of a Nationwide Survey and Comparison with International Guidelines.Urology Research & Practice Jul 2023The aim of this study is to evaluate current urologic practice regarding the management of priapism in Turkey and compare with international guidelines.
OBJECTIVE
The aim of this study is to evaluate current urologic practice regarding the management of priapism in Turkey and compare with international guidelines.
METHODS
Urologists and urology residents were invited to an online survey consisting of 30 multiple-choice questions on priapism-related clinical practices that were consid- ered most important and relevant to practices by using Google Forms.
RESULTS
Total number of responses was 340. Respondents reported that they recorded a detailed patient's medical history and physical examination findings (n = 340, 100%) and laboratory testing, which includes corporal blood gas analysis (n=323, 95%). Participants announced that they performed Doppler ultrasound for 1/4 cases (n = 106, 31%), but 22% of the participants (n=75) replied that they performed in >75% of cases. Participants (n=311, 91%) responded that the first-line treatment of ischemic priapism is decompression of the corpus cavernosum. Moreover, most respondents (n = 320, 94%) stated that sympathomimetic injection drugs should be applied as the second step. About three-quarters of respondents (n = 247, 73%) indicated adrenaline as their drug of choice. Phosphodiesterase type 5 inhibitors seems to be the most pre- ferred drug for stuttering priapism (n=141, 41%). Participants (n=284, 84%) replied that corpora-glanular shunts should be preferred as the first. A large number of par- ticipants (n = 239, 70%) declared that magnetic resonance imaging can be performed in cases with delayed (>24 hours) priapism to diagnose corporal necrosis. Most of the participants (84%) responded that penile prosthesis should be preferred to shunts in cases with delayed (>48 hours) priapism.
CONCLUSION
It would be appropriate to improve the training offered by professional associations and to give more training time to the management of priapism during residency.

Review
PURPOSE
Electronic cigarette (e-cig) use is prevalent. The health implications of e-cig use on the genitourinary (GU) system are uncertain. This systematic review aims to evaluate how e-cig use impacts the GU system.
METHODS
A systematic search was conducted in PubMed, Embase and Ovid alongside citation searching. Review articles, non-English papers, animal model/cell line studies or articles only on combustible cigarettes were excluded. Quality assessment was undertaken using the Joanna Briggs Institute checklists. The primary endpoint was the impact of e-cig use on bladder cancer incidence. Secondary outcomes included urinary carcinogens, chronic kidney disease (CKD), reproductive disorders, and other GU diseases.
RESULTS
The search yielded 244 articles, 28 were ultimately included. One study assessed risk of bladder cancer and found the use of e-cig was associated with an increased odds ratio of 1.577 for its diagnosis. Twenty-one articles measured potential urinary carcinogens-including crotonaldehyde and benzene-associated with bladder cancer. Two articles evaluated the association of e-cig use with CKD and reported mixed outcomes. Three articles reported on reproductive disorders, specifically, stuttering priapism and changes to sperm quantity and quality. One study reported on other GU diseases, specifically burns to the GU system. After quality assessment, all articles were deemed to be of acceptable quality for inclusion.
CONCLUSIONS
E-cig use was associated with an increased risk of bladder cancer, increased exposure to carcinogenic compounds, mixed evidence on CKD, increased risk of reproductive disorders and burns to the GU system. Further studies are needed to understand long-term GU effects.

Review
BACKGROUND
Recently, case reports of priapism associated with the use of some anti-seizure medications began to emerge in the literature. We aimed to investigate if there is a potential safety signal of priapism among individual anti-seizure medications and to search the literature for relevant published cases.
RESEARCH DESIGN AND METHODS
We conducted a disproportionality analysis using OpenVigil 2.1 to query the United States Food and Drug Administration's Adverse Event Reporting System (FAERS) database. Literature search was conducted in PubMed/MEDLINE, Scopus and Web of Science up to 12 July 2023.
RESULTS
We identified positive signal of priapism for valproic acid and its derivatives ( = 23, chi-squared = 59.943, PRR = 4.566), gabapentin ( = 20, chi-squared = 9.790, PRR = 2.060), lamotrigine ( = 16, chi-squared = 8.318, PRR = 2.120), levetiracetam ( = 16, chi-squared = 10.766, PRR = 2.329), topiramate ( = 14, chi-squared = 28.067, PRR = 3.972) and carbamazepine ( = 8, chi-squared = 6.147, PRR = 2.568), as well as published cases of priapism associated with these drugs. We also found published cases of priapism for pregabalin and phenytoin in the literature and FAERS, and at least one reported adverse event of priapism in FAERS for clonazepam, lacosamide, ethosuximide, oxcarbazepine, and vigabatrin in which they were considered primary suspect.
CONCLUSIONS
Our study identified signals for priapism for several anti-seizure medications, but these results need to be confirmed in well-designed pharmacoepidemiological studies.

We present a case of medication-induced priapism that was refractory to conventional urologic methods and required treatment with a caverno-saphenous bypass. The patient had been misusing an injectable erectile dysfunction medication consisting of alprostadil, papaverine, and phentolamine (Trimix), resulting in multiple episodes of priapism. His initial episodes of priapism were successfully treated with the traditional urologic algorithm, including phenylephrine, aspiration, and distal shunting. However, due to his continued medication misuse, these became ineffective, requiring proximal shunt surgery. Priapism requiring an extra-anatomic bypass is exceedingly rare. Following our proximal shunt surgery, he maintained partial sexual function, and his bypass remained patent.

Sickle cell disease (SCD) is an important topic for emergency medicine audiences because complications of the disease account for a large proportion of hematologic emergencies that are seen in the emergency department each year. Early recognition and aggressive management of emergency complications of SCD can help to reduce the morbidity and mortality associated with this disease. While the treatment recommendations for some complications of SCD are based on expert opinion, there has been advancement in the understanding of the pathogenesis of the disease and evidence regarding the treatment options available for managing acute complications. This continuing medical education article will provide a summary of the clinical manifestation and management of the most common acute complications of SCD: infection, vaso-occlusive episode, acute chest syndrome, splenic sequestration, stroke, and priapism.

INTRODUCTION
Ischemic priapism is a medical emergency that, if not treated, could lead to permanent erectile dysfunction. The association between cocaine and priapism is well-known; however, data on patient characteristics, treatment, and outcomes is missing. This work aimed to answer the research question: What are the characteristics, management strategies, and erectile prognosis of patients consuming cocaine and presenting with priapism?
METHODS
We conducted a systematic review according to PRISMA guidelines and described our case series.
RESULTS
Eight studies were selected for qualitative synthesis, presenting information on ten patients. In our case series, we showed information regarding four patients. From the systematic review, the mean presentation time was 42.6 h, and the mean number of procedures to solve priapism was 2,4; in our case series was 42.75 h and 2, respectively.
CONCLUSION
Cocaine-related priapism might present with a delayed diagnosis, need more procedures to be managed, and have a worse prognosis. More extensive and prospective studies are required.

Priapism, characterized by prolonged and painful penile erection, is a rare urological emergency with diverse etiologies. We present a case of refractory ischemic priapism following hemodialysis in a 57-year-old male with a history of type II diabetes mellitus, hypertension, and end-stage renal disease. Despite standard conservative management, the patient's condition persisted, necessitating penile distal shunting through an intracorporeal dilatation plus Al-Ghorab corporoglandular shunt. Blood gas analysis of corpus cavernosum blood revealed severe acidosis and hypoxemia, emphasizing the systemic impact of ischemic priapism. The patient's history of erythropoietin injections and the administration of heparin during dialysis emerged as potential contributors to priapism. We discuss the complex interplay between erythropoietin, coagulation cascade, and heparin in the context of priapism development. The case underscores the need for further research to understand the specific mechanisms contributing to priapism in patients undergoing hemodialysis.

We aimed to provide evidence on the trends and in-hospital outcomes of patients with low- and high-flow priapism through the largest study in the field. We used the GeRmAn Nationwide inpatient Data (GRAND), provided by the Research Data Center of the Federal Bureau of Statistics (2008-2021), and performed multiple patient-level analyses. We included 6,588 men with low-flow and 729 with high-flow priapism. Among patients with low-flow priapism, 156 (2.4%) suffered from sickle cell disease, and 1,477 (22.4%) patients required shunt surgery. Of them, only 37 (2.5%) received a concomitant penile prosthesis implantation (30 inflatable and 7 semi-rigid prosthesis). In Germany, the total number of patients with low-flow priapism requiring hospital stay has steadily increased, while the number of patients with high-flow priapism requiring hospital stay has decreased in the last years. Among patients with high-flow priapism, 136 (18.7%) required selective artery embolization. In men with low-flow priapism, sickle cell disease was associated with high rates of exchange transfusion (OR: 21, 95% CI: 14-31, p < 0.001). The length of hospital stay (p = 0.06) and the intensive care unit admissions (p = 0.9) did not differ between patients with low-flow priapism due to sickle cell disease versus other causes of low-flow priapism. Accordingly, in men with high-flow priapism, embolization was not associated with worse outcomes in terms of length of hospital stay (p > 0.9), transfusion (p = 0.8), and intensive care unit admission (p = 0.5). Low-flow priapism is an absolute emergency that requires shunt surgery in more than one-fifth of all patients requiring hospital stay. On the contrary, high-flow priapism is still managed, in most cases, conservatively.
