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.

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.

Review
Priapism is defined as a persistent penile erection lasting more than 4 h. We searched the literature for reviews, case reports, and series for patients with lymphoproliferative disorders who developed priapism. The search involved all the lymphoproliferative disorders included in the revised 2016 World Health Organization classification of lymphoid neoplasms including chronic lymphocytic leukemia, multiple myeloma, Waldenström macroglobulinemia, and lymphomas. A total of 16 articles were found. The search included cases up to 4 January 2021. Priapism was seen most commonly as the first manifestation of lymphoproliferative disorders, rarely seen after treatment or after diagnosis.

This literature review presents two unusual and mystifying disorders of penile erection: painful nocturnal erections, alternatively termed sleep-related painful erections, and idiopathic stuttering priapism, a variant of recurrent ischemic priapism in which no cause is discernible. The disorders are closely related although they are distinct clinically and pathologically. The main subject areas of discussion are recognition, clinical evaluation and management although current concepts surrounding their causes and mechanisms are also addressed. It is acknowledged that despite the perceived rarities of these disorders they are impactful in terms of their disease profiles and consequences. Future advances in their management will require continued development of evidence-based treatments.

BACKGROUND
Penile Doppler ultrasound (PDU) is suggested to be an alternative to blood gas analysis (BGA) from the corpora cavernosa in differentiating between high- and low-flow priapisms, with limited supportive evidence.
AIM
To compare penile Doppler ultrasound study and blood gas analysis in the diagnosis of priapism, through a systematic review of the literature.
METHODS
Studies were identified by literature search of Medline, Scopus, Cochrane and ClinicalTrials.Gov. Studies were included if their participants had priapism evaluated by Penile Doppler ultrasound, and reported data on the blood gas analysis or pudendal artery angiography (PAA). Two authors independently extracted the articles using predetermined datasets, including indicators of quality.
OUTCOMES
Correlation of penile Doppler ultrasound with blood gas analysis and pudendal artery angiography.
RESULTS
Twelve studies were included. Three studies compared Penile Doppler ultrasound to blood gas analysis and pudendal artery angiography. Penile Doppler ultrasound was used as adjunctive to blood gas analysis to differentiate low flow from high flow priapism, guidance for embolization, etiological diagnosis in three studies. Compared to pudendal artery angiography, penile Doppler ultrasound had a sensitivity of 40-100% and a specificity of 73%, to localize vascular injury and anatomical abnormalities (two studies). Penile Doppler ultrasound was also used for the follow-up after the treatment of priapism (two studies). No study reported an impact on functional results or a delay of management due to penile Doppler ultrasound use.
CLINICAL TRANSLATION
We reviewed evidence on penile Doppler ultrasound study in priapism. Penile Doppler ultrasound study performance was comparable to blood gas from corpus cavernosum. It is recommended to use doppler as an alternative diagnostic tool.
STRENGTHS & LIMITATIONS
Our systematic review had limitations. Firstly, the number of cases in the included studies was small. Secondly, these studies were all retrospective. Lastly, few data were reported with regards to hemodynamic parameters of penile Doppler ultrasound, and the majority of studies did not describe these in detail.
CONCLUSIONS
Evidence supports that penile Doppler ultrasound is a reliable way for differentiating high-flow and low-flow priapism. We recommend penile Doppler ultrasound study as an alternative of blood gas analysis from corpus cavernosum, especially when the latter is not available.

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.

The Journal of Sexual Medicine May 2022In 2016, we reported the first case of high flow priapism and arteriocavernosal fistula caused by penile prosthesis insertion that mimicked device autoinflation. (Review)
Review
BACKGROUND
In 2016, we reported the first case of high flow priapism and arteriocavernosal fistula caused by penile prosthesis insertion that mimicked device autoinflation.
AIM
To raise awareness amongst implanters, we describe further cases from our institution and perform a systematic review of the literature to understand the rarity of this phenomenon.
METHODS
Patient demographics, management and outcomes were extracted retrospectively. A systematic search of the EMBASE, PubMed and PubMed Central libraries for studies reporting arteriocavernosal fistula mimicking autoinflation since 1946 was performed.
OUTCOMES
To identify and report all known cases of high flow priapism and arteriocavernosal fistula presenting as autoinflation of an inflatable penile prosthesis.
RESULTS
Four patients in total (median age 56, range 46-60 years) were identified. Catastrophic bleeding (1.8L) occurred during revision surgery for presumed autoinflation in Patient 1 and subsequent ultrasound (US) confirmed a fistula which was embolized. Patient 2 redeveloped autoinflation following revision surgery. Ultrasound confirmed high flow priapism from an arteriocavernosal fistula. Patient 3 underwent penile magnetic resonance imaging (MRI) to investigate autoinflation and residual penile curvature. MRI showed a tumescent penis despite a deflated device and the fistula was embolized successfully. Patient 4 with sleep-related painful erections did not improve following insertion of penile prosthesis. Doppler US identified 2 fistulae that was embolized but with no resolution of symptoms. Subsequent embolization of both common penile arteries were done to control his symptoms. No other publications apart from the published abstract from 2016 reporting patient 1 was found.
CLINICAL IMPLICATIONS
If considered prior to revision surgery, the fistula can be managed safely by minimally invasive percutaneous angioembolisation avoiding surgery which can potentially be associated with significant complications.
STRENGTHS AND LIMITATIONS
The rarity of this phenomenon was supported by a systematic review. Our study however does present the findings from a small number of patients.
CONCLUSION
Damage to the cavernosal artery during inflatable penile prosthesis insertion can create an arteriocavernosal fistula that mimics autoinflation, leading to catastrophic intra-operative bleeding or unnecessary surgery.

BACKGROUND
Priapism is defined as a penile erection that persists four or more hours and is unrelated to sexual stimulation. Priapism resulting from hematologic malignancy is most likely caused by venous obstruction from microemboli/thrombi and hyperviscosity caused by the increased number of circulating leukocytes in mature and immature forms. In patients with leukemia, 50% of cases of priapism are due to Chronic Myeloid Leukemia (CML). We present a systematic review of priapism in CML. Acquisition of evidence: An extensive literature research was carried out in PubMed, Google Scholar, SCOPUS, and Science Citation Index databases... The search included cases up to 4th August 2020. Synthesis of evidence: A total of 68 articles were found and included in our review, including 3 reviews from three different centers. We found 68 articles (102 patients; figure 1) and several case reports on priapism in CML. Priapism was noticed in some patients at the first presentation of CML. However, it was infrequently reported during the start of treatment, following the stop of medication and post-splenectomy. The mean age at presentation was 27.4 years, and the mean time from onset of priapism to the time to get medical attention (presentation) was 78.2 hours. The mean white blood cell count associated with priapism was 321.29x109/L, and the mean platelet count was 569 x10 9/L. The chronic phase of CML was the most common phase where priapism occurred. Most patients were Asian (>50%). Nearly a quarter of patients (27.4%) developed permanent erectile dysfunction.
CONCLUSIONS
Priapism is a urological emergency requiring urgent multidisciplinary management to prevent erectile dysfunction. Because of the relatively rare occurrence of priapism in CML patients, there is no standard treatment protocol.

Review
Sickle cell anemia is a hemoglobinopathy that causes complications such as Vaso-Occlusive Crisis (VOC), stroke, priapism, Acute Chest Syndromes (ACS), and bone infarcts due to blood vessel occlusion, resulting in hypoxia, ischemia, and inflammation. Preventing these incidents improves the quality of life and lowers mortality rates in Sickle Cell Disease (SCD) patients. This systematic review aims to describe the drugs, their mechanisms of action, dosages, changes in hemoglobin parameters, decrease in VOCs, delay the time for the next VOC, decrease in the length of hospital stay, and side effects associated with these drugs. This review adheres to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020 guidelines. For this review, we searched the PubMed, Google Scholar, and Cochrane databases and screened them for full free texts published in English and studied in humans in the last five years beginning in 2018. Randomized clinical trials (RCT), observational studies, meta-analyses, systemic reviews, and traditional reviews were all included in the search. According to the type of study, quality assessment tools are used, and eight papers are chosen. Full-text articles from these papers are studied, analyzed, and tabulated. We discussed seven interventions that are used to treat sickle cell disease. Voxelotor, crizanlizumab, L-glutamate, long-term blood transfusions, Zinc (Zn), Niprisan®, and Ciklavit* were found to reduce the number and severity of VOC. We discovered that VOCs containing L -glutamate reduced the length of hospitalization. Magnesium (Mg) did not affect the number and severity of VOCs. This review includes a few articles for the study. Future papers on this subject should include a large sample size and many papers. More clinical trials are required to evaluate the dosages and outcomes of using these drugs in combination to prevent VOCs.

Review
What is the effectiveness of surgical and non-surgical therapies in the treatment of ischemic priapism in patients with sickle cell disease? A systematic review by the EAU Sexual and Reproductive Health Guidelines Panel.
Sickle cell disease (SCD) is an inherited hemoglobin disorder characterized by the occlusion of small blood vessels by sickle-shaped red blood cells. SCD is associated with a number of complications, including ischemic priapism. While SCD accounts for at least one-third of all priapism cases, no definitive treatment strategy has been established to specifically treat patients with SC priapism. The aim of this systematic review was to assess the efficacy and safety of contemporary treatment modalities for acute and stuttering ischemic priapism associated with SCD. The primary outcome measures were defined as resolution of acute priapism (detumescence) and complete response of stuttering priapism, while the primary harm outcome was as sexual dysfunction. The protocol for the review has been registered (PROSPERO Nr: CRD42020182001), and a systematic search of Medline, Embase, and Cochrane controlled trials databases was performed. Three trials with 41 observational studies met the criteria for inclusion in this review. None of the trials assessed detumescence, as a primary outcome. All of the trials reported a complete response of stuttering priapism; however, the certainty of the evidence was low. It is clear that assessing the effectiveness of specific interventions for priapism in SCD, well-designed, adequately-powered, multicenter trials are strongly required.
