Abstract
Background: Hydroxyzine hydrochloride is a piperazine derivative antihistamine that is used in the treatment of anxiety. Its tendency to cause somnolence makes it an attractive option for patients with anxiety-induced insomnia. Despite its antihistamine activity, hydroxyzine is noted to have alpha-adrenergic antagonism activity. Other alpha-adrenergic inhibitors have been implicated in medication-induced priapism, including risperidone. Risperidone is a second-generation antipsychotic that primarily blocks serotonin and dopamine receptors, while also inhibiting alpha-1 and alpha-2 receptors with high affinity. Objective: We report a case of a first-of-its-kind case report of a patient who was stable on risperidone and presented with priapism after taking hydroxyzine nightly for the previous 10 days. Results: A 35-year-old male with a past psychiatric history of depression, generalized anxiety disorder, schizoaffective disorder, presented to the emergency department with priapism for 15 hours that required intracaveronsal phenylephrine hydrochloride and manual drainage to achieve detumescence. The patient was on a stable dose risperidone but reported taking hydroxyzine 50 mg nightly for anxiety and insomnia 10 days prior to emergency department admission. Upon resolution of the priapism, the patient stopped hydroxyzine, but continued risperidone. The patient had another prolonged erection 10 days after stopping hydroxyzine; however, he reported that it resolved spontaneously without intervention after 4 hours. Conclusion: This case report demonstrates the risk of addition of hydroxyzine to antipsychotics which can result in an increased risk of priapism or prolonged episodes.

Abstract
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.

Clinical Practice Patterns for Surgical Shunts and Penile Prosthesis Placement in Men With Priapism: A Retrospective Large Claims Database Analysis. UROLOGY PRACTICE 2024; 11:507-513. [PMID: 38526420 DOI: 10.1097/upj.0000000000000558] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Accepted: 02/22/2024] [Indexed: 03/26/2024]
Abstract
INTRODUCTION The objective of this study was to assess the rates of surgical shunting and prosthesis placement for acute ischemic priapism using a large multi-institutional claims database. METHODS A US claims database network (TriNetX Diamond Network) was queried from 2010 to 2020. We constructed a cohort of men ages ≥ 16 years who (1) had a diagnosis of priapism and (2) underwent an irrigation of the corpora cavernosa for priapism. We assessed the number of men who then had a surgical penile shunt or penile prosthesis placement. Demographics, time to surgical procedure, and order of procedures were collected. RESULTS A total of 6392 men were identified with the diagnosis of priapism and the procedure of corpora cavernosal irrigation. Of these men, 693 (11%) proceeded to surgical shunt. One hundred forty-four men (2%) underwent initial penile prosthesis placement. Of the men undergoing initial penile prosthesis, only 17 of 144 (12%) cases occurred within the first month of corpora cavernosal irrigation. Finally, when assessing choice of initial shunts vs initial penile prosthesis before and after 2015, overall rates of initial shunt (10.0% vs 8.5%, P < .0001) and initial prosthesis (3.1% vs 2.1%, P < .0001) were lower after 2015 when compared with rates prior to 2015. CONCLUSIONS In this US claims-based analysis of men presenting with ischemic priapism and treated with initial irrigation, a small percentage (11%) of men went on to receive surgical shunting, and only 2% received an initial prosthesis. Men receiving initial prostheses were more likely to have more comorbidities, and overall surgical management of priapism has decreased over time.

Abstract
This report documents the treatment of a 41-year-old male with sickle cell disease (SCD) and repeated stuttering priapism using crizanlizumab, which alleviated the priapism but induced a significant vaso-occlusive crisis during the second infusion. Encouragingly, no subsequent vaso-occlusive crises occurred. However, the potential for infusion-related adverse events warrants close supervision. Further research is necessary to explore its full benefits on priapism management.

Abstract
Priapism is a painful and persistent erection, with or without sexual stimulation. A rare cause of such abnormality is chronic myeloid leukemia. Few cases of priapism as an initial manifestation of this type of leukemia have been reported in adolescent patients. Here we describe the case of a 16-year-old patient who presented with priapism as the initial manifestation of chronic myeloid leukemia. No cavernosal aspiration was performed. A specific hematological treatment was started and, given the persistence of priapism, the patient required 2 corpora cavernosa shunt procedures; despite this treatment, there is a high probability of sequelae.

Abstract
Fournier's gangrene is a rare and potentially life-threatening type of necrotizing fasciitis that affects the genital and perineal regions. Malignant priapism is a rare and serious medical condition characterized by persistent and painful erection of the penis that is not associated with sexual arousal or stimulation. We present a case of a 77-year-old man with concurrent Fournier's gangrene and malignant priapism. He first underwent surgical debridement to remove necrotic tissue and aspiration of blood from the corpora cavernosa. Then a palliative penectomy was performed. The patient succumbed to severe sepsis and died after 14 days of hospitalization.

Abstract
INTRODUCTION Refractory priapism, characterized by persistent and prolonged painful erections despite initial treatment maneuvers, can significantly impair erectile function secondary to ischemia-induced corporal tissue fibrosis. These patients will likely require subsequent penile prosthesis (PP) surgery to regain sexual activity, yet consensus regarding the optimal timing of implantation remains lacking. OBJECTIVES To evaluate and compare the clinical outcomes associated with early vs delayed PP implantation in individuals with priapism-induced erectile dysfunction (ED). METHODS We included studies that focused on refractory priapism leading to ED and its management with PP implantation. We assessed cohort study bias with a risk-of-bias tool and case series bias with the modified Newcastle-Ottawa Scale. Pooled odds ratios (ORs) were calculated by a fixed-effect model. RESULTS We included 9 studies, comprising 4 cohort studies and 5 case series, involving a total of 278 patients. Total complications were higher in the delayed group (OR, 4.16; 95% CI, 2.77-6.26). Fibrosis was significantly more pronounced in the delayed group (OR, 118.18; 95% CI, 20.06-696.32). The odds of erosion, infections, and penile injury did not show statistically significant differences between the groups (OR, 2.52 [95% CI, 0.67-9.49], 0.89 [0.38-2.10], 1.83 [0.79-4.26], respectively). Patients' satisfaction resulted in a pooled OR of 0.15 (95% CI, 0.04-0.49) in favor of the early PP insertion group. CONCLUSION The results from this study favor an early approach to ED (within 30 days) following ischemic priapism. However, it is important to consider patients' preferences, values, and psychological factors to make an informed decision.

Abstract
A 39-year-old male with a medical history significant for migraine, psoriatic arthritis, postural orthostatic tachycardia syndrome (POTS), vitamin D deficiency and hypoglycemia presented with a two-year history of sleep-related painful erections (SRPE). Since the reported prevalence is low, there is limited understanding of the possible etiologies of the disorder and little published clinical data on treatment algorithms. Thus, he had tried multiple therapies. Baclofen was effective but not tolerated. Pelvic physiotherapy and tadalafil were ineffective. Imipramine, clonazepam, vitamin B, iron, and selenium provided minimal benefit. Opiates were initially effective, but lost efficacy after 2-3 weeks. Finally, he was started on sodium oxybate after fully counseling the patient on the potential side effects of the treatment and consenting the patient for off-label use. This has effectively treated his SRPE. Sodium oxybate is a novel therapy for and a possible new treatment for this rare and challenging disorder that merits further study.

Abstract
Introduction We present a case of ischemic priapism caused by self intracavernous injection of tadalafil. Case presentation A 77-year-old man developed priapism due to self-injection of tadalafil into the corpus cavernosum. He presented to our hospital 2 days after the development of priapism and severe penile pain. The blood gas analysis of the corpus cavernosum revealed ischemic priapism. At first, we performed percutaneous distal shunt (T-shunt) and cavernosal irrigation, resulting in slight improvement of penile tumescence. Several hours later, penile tumescence and severe pain reappeared. Bilateral proximal (corpora-spongiosal) shunt was performed under anesthesia again. Penile tumescence was slowly and gradually relieved. His erectile function was declined. Conclusion We experienced a case of priapism due to self intracavernous administration of tadalafil who needed a proximal shunt to relieve the severe penile pain. This case report may serve as a warning for physicians and patients not to use phosphodiesterase 5 inhibitor inappropriately.

Abstract
Acute lymphoblastic leukemia (ALL) in pediatric patients typically presents with recognizable symptoms such as fever, pallor, and bone pain. However, atypical manifestations can complicate the diagnostic landscape. We present a unique case of a seven-year-old male with T-cell ALL whose presenting symptom was priapism. This case underscores the need for heightened awareness among healthcare professionals regarding the diverse clinical presentations of leukemia, emphasizing the importance of a multidisciplinary team approach for comprehensive evaluation and management. Our seven-year-old patient presented with priapism. A comprehensive diagnostic workup, including complete blood counts and subsequent bone marrow examination, led to the diagnosis of T-cell ALL. Given the rare presentation, a multidisciplinary team consisting of pediatric oncologists/hematologists, urologists, and other relevant specialists collaborated to formulate a tailored treatment plan. The patient received an intensified chemotherapy regimen, resulting in the resolution of priapism and hematologic improvement. Priapism as an initial presentation of T-cell ALL in a pediatric patient is an exceptional occurrence, necessitating a specialized and collaborative approach to diagnosis and management. This case report highlights the importance of interdisciplinary coordination involving pediatric oncologists and urologists in addressing the unique challenges posed by atypical leukemia presentations. The rarity of this manifestation emphasizes the need for further research to elucidate the underlying mechanisms and establish optimal management strategies for similar cases.

Abstract
Objectives To evaluate clinical characteristics associated with survival in patients with metastases to the penis. Methods After approval by the IRB, records of collaborating centres in Leuven, London, Rostock, Amsterdam and Tampa were screened for men presenting with metastatic disease to penis. Multivariate logistic regression analyses were used to identify covariables associated with survival. We analysed clinical data on 34 patients. Results Primary sites were most frequently prostate (n = 14, 41%) and bladder (n = 9, 26%). Twenty-eight of 34 (82%) presented with metachronous penile metastases, and 11 (32%) patients had penile metastases as the sole metastatic site. Penile metastatic locations were most frequently in the corpora (n = 18; 53%). Seven (21%) patients with penile metastases had priapism on presentation. Systemic therapy was frequent and variable (chemotherapy n = 12; immunotherapy n = 5; hormones n = 3). Local management included either surgery (n = 10) or RT (n = 8). Twelve- and 24-month overall survival rate were 67% and 35%, respectively. No clinical parameter including primary histology, synchronous or metachronous metastases or priapism showed statistical survival benefit or detriment. Conclusion Metastasis to penis arises most frequently from pelvic primaries. Priapism does not appear to correlate with survival in this large, well-defined series.

Abstract
PURPOSE To explore the differences of priapism events among a diverse cohort taking erectogenic medicines (i.e., phosphodiesterase type 5 inhibitors [PDE5i] and intracavernousal drugs). METHODS We queried the World Health Organization global database of individual case safety reports (VigiBase) for records of the adverse drug reactions (ADR) with sildenafil, tadalafil, avanafil, vardenafil, papaverine, and alprostadil. Disproportionality analyses (case/non-case approach) were performed to assess the reporting odds ratio (ROR) of priapism reporting in PDE5i consumers compared to intracavernousal drug recipients. RESULTS From a total of 133 819 ADR events for erectogenic medications, 632 were priapism (PDE5is: n = 550, 0.41%; intracavernousal drugs: n = 82, 9.92%). Priapism disproportionality signals from intracavernousal drugs were 25 times stronger than PDE5is (ROR = 34.7; confidence interval [CI] 95%: 27.12-43.94 vs. ROR = 1.38; 95% CI: 1.24-1.54). For all PDE5i agents, the 12-17 years age group had the highest ROR (9.49, 95% CI: 3.76-19.93) followed by 2-11 years (4.31, 95% CI: 1.57-9.4). Disproportionality signals for consumers under 18 for both all PDE5is as a whole (ROR = 4.57, 95% CI: 2.48-7.73) and sildenafil (ROR = 4.89, 95% CI: 2.51-8.62) were stronger than individuals 18 or older (ROR = 1.06, 95% CI: 0.93-1.21 and ROR = 1.08, 95% CI: 0.91-1.26, respectively). CONCLUSIONS PDE5i use shows disproportionate priapism signals which are higher in young patients.

Abstract
BACKGROUND Injectable hyaluronic acid (HA) gel has emerged as a widely used soft tissue filler for surgeries. In penile reconstructive surgery, HA gel has been employed for penile or glans augmentation in selected patients diagnosed with micropenis. This augmentation technique involves injecting the gel into submucosal tissue and increasing the size of the penis for approximately 1 year. A few studies have investigated the possible complications correlated with medically assisted penile injections of HA gel. However, no previous reports have shown the complications of self-administered HA injection. This case report aims to present the first documented case of ischaemic priapism as a complication of self-administered HA injection. CASE PRESENTATION We present the case of a 43-year-old male who self-administered a 20 mL injection of HA into the dorsal side of his penis. The injected material probably reached the corpora cavernosa, leading to priapism within a few hours. However, the patient did not seek medical attention until 72 h later. The first two initial conservative attempts of blood drainage were unsuccessful because the gel had obstructed vein drainage, causing the penis to remain in a state of priapism. The final treatment approach involved shunting, high enoxaparin doses and oral Effortil administration. CONCLUSIONS While complications from medically assisted HA injections have been documented, this case report sheds light on the complications arising from self-administered penile injections. Priapism is a severe medical condition that requires immediate treatment to avoid potentially serious long-term consequences. Healthcare providers and patients must acknowledge its symptoms and its appropriate course of treatment, especially in the context of penile medical injections.

Abstract
Malignant priapism (MP) is defined as a condition of persistent erection of the penis without sexual stimulation due to the neoplastic process of the cavernous sinus and the efferent veins. The effectiveness of established therapeutic recommendations in priapism was ineffective in MP. Modalities of therapy for MP varied from medication treatment, nonsurgical treatment, surgical treatment, and radiotherapy. Despite aggressive surgical management combined with radiation therapy, chemotherapy, or targeted therapy, the survival rate remains low. Therefore, the treatment is usually palliative, focusing on the patient's quality of life improvement and symptom relief.

Abstract
BACKGROUND Despite their efficacy and general safety, rare but devastating adverse drug reactions have been associated with phosphodiesterase type 5 inhibitors. OBJECTIVES To determine the safety profile of oral phosphodiesterase type 5 inhibitors with a particular focus on priapism and malignant melanoma. MATERIALS AND METHODS In this case-non-case study, we queried the individual case safety reports for phosphodiesterase type 5 inhibitors within the World Health Organization global database of individual case safety reports (VigiBase) between 1983 and 2021. We included all individual case safety reports for sildenafil, tadalafil, vardenafil, and avanafil in men. For comparison, we also extracted the safety data from the Food and Drug Administration trials for these drugs. We assessed the safety profile of phosphodiesterase type 5 inhibitors by disproportionality analysis by measuring reporting odds ratio for their most commonly reported adverse drug reactions, once for all phosphodiesterase type 5 inhibitor reports and once for reports of oral phosphodiesterase type 5 inhibitor use in adult men (≥18 years old) with sexual dysfunction. RESULTS A total of 94,713 individual case safety reports for phosphodiesterase type 5 inhibitors were extracted. A total of 31,827 individual case safety reports were identified relating to adult men taking oral sildenafil, tadalafil, vardenafil, or avanafil for sexual dysfunction. The most common adverse drug reactions included poor drug efficacy (42.5%), headache (10.4% vs. 8.5%-27.6% [Food and Drug Administration]), abnormal vision (8.4% vs. ≤4.6% [Food and Drug Administration]), flushing (5.2% vs. 5.1%-16.5% [Food and Drug Administration]), and dyspepsia (4.2% vs. 3.4%-11.1% [Food and Drug Administration]). Priapism showed significant signals for sildenafil (reporting odds ratio = 13.81, 95% confidence interval: 11.75-16.24), tadalafil (reporting odds ratio = 14.54, 95% confidence interval: 11.56-18.06), and vardenafil (reporting odds ratio = 14.12, 95% confidence interval: 8.36-22.35). Comparing with other medications in VigiBase, sildenafil (reporting odds ratio = 8.73, 95% confidence interval: 7.63-9.99) and tadalafil (reporting odds ratio = 4.25, 95% confidence interval: 3.19-5.55) had significantly higher reporting odds ratios for malignant melanoma. CONCLUSION Phosphodiesterase type 5 inhibitors show significant signals correlating with priapism among a large international cohort. Further clinical study is needed to elucidate whether this is from proper or inappropriate use or other confounding conditions, as analysis of pharmacovigilance data does not allow for quantifying the clinical risk. Also, there appears to be a relationship between phosphodiesterase type 5 inhibitor use and malignant melanoma, which warrants additional study to better understand causation.

Abstract
Priapism is a urologic emergency requiring prompt management. There are three types of priapism: stuttering (intermittent), non-ischemic (high-flow/arterial), and ischemic (low-flow/veno-occlusive). Here, we present the first case of an infant with recurrent non-ischemic priapism as the first sign of severe hypertension. An 11-month-old infant was admitted to the hospital for high-flow priapism. On admission, he was found to have severe hypertension that required a combination of five antihypertensive drugs; abdominal ultrasound showed polycystic kidneys, splenomegaly, and a parenchymal liver lesion. The priapism resolved spontaneously and did not recur again after the initiation of antihypertensive treatment. Genetic analysis confirmed autosomal recessive polycystic kidney disease (ARPKD). We found no other explanation for the priapism, such as genital trauma, hematologic disease, or anything else. Decreased nitric oxide (NO) bioavailability seen in patients with hypertension seems to be the principal mechanism of hypertension causing priapism. This hypothesis is supported by animal models of genetically modified mice lacking nitric oxide synthase. The same mechanism is thought to be the genesis of priapism and other complications, such as pulmonary hypertension, in patients with sickle cell disease. We present a case of severe hypertension-associated priapism in a child with unrecognized ARPKD. The endothelial dysfunction with decreased NO bioavailability seen in patients with hypertension may be the principal pathogenic mechanism.

[PMID: 37745750 PMCID: PMC10516446 DOI: 10.7759/cureus.45475] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/18/2023] [Indexed: 09/26/2023] Open
Abstract
Purpose The purpose of this research is to examine the impact of syringic acid on ischemia-reperfusion injury in cavernosal tissue, utilizing a rat model of induced priapism. Materials and methods A total of 24 rats were allocated into three groups. Group 1 was designated as the control group, while Group 2 underwent ischemia-reperfusion injury assessment using the priapism model. Group 3 underwent the same procedures as Group 2, with the addition of intraperitoneal administration of syringic acid (100 mg/kg) 60 min after priapism initiation. All rats underwent penectomy, and sufficient blood samples were collected. Histopathological assessment of penile cavernosal tissue involved grading tissue damage, inflammation, vasocongestion, desquamation, and edema on a scale of 0-3 (0: normal, 1: mild, 2: moderate, 3: severe). Result Significant differences were observed among the three groups in terms of IL-1 beta and TNF-alpha levels (p=0.001 and p<0.001, respectively). IL-1 beta and TNF-alpha levels in Group 2 were found to be significantly higher than Group 3 (p=0.003 and p=0.004). There was also a significant difference among the three groups in terms of median MDA levels (p<0.001). Furthermore, the median MDA level in Group 2 was found to be significantly higher than that in Group 3 (p<0.001). While significant differences were observed among the three groups in terms of median SOD and GSH-px levels, no significant difference was found among the groups in terms of median PC levels (p=0.004, p= 0.048, and p=0.159, respectively). In direct microscopic examination, a significant improvement in pathological scores was noted in Group 3 compared to Group 2 (p<0.001). Conclusion Syringic acid demonstrated protective properties against ischemia-reperfusion injury caused by priapism in cavernosal tissue.

Priapism at Diagnosis of Pediatric Chronic Myeloid Leukemia: Data Derived from a Large Cohort of Children and Teenagers and a Narrative Review on Priapism Management. J Clin Med 2023; 12:4776. [PMID: 37510891 PMCID: PMC10380995 DOI: 10.3390/jcm12144776] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 07/04/2023] [Accepted: 07/13/2023] [Indexed: 07/30/2023] Open
Abstract
Pediatric chronic myeloid leukemia (CML) is a very rare malignancy (age-related incidence 0.1/100,000) typically presenting with leucocyte counts >100,000/µL. However, clinical signs of leukostasis are observed at diagnosis in only approximately 10% of all cases and among these, priapism is infrequent. Here, we analyze data from pediatric CML registries on the occurrence of priapism heralding diagnosis of CML in 16/491 (3.2%) boys (median age 13.5 years, range 4-18) with pediatric CML. In the cohort investigated, duration of priapism resulting in a diagnosis of CML was not reported in 5 patients, and in the remaining 11 patients, occurred as stuttering priapism over 3 months (n = 1), over 6 weeks (n = 1), over 1-2 weeks (n = 2), over several days (n = 2), or 24 h (n = 1), while the remaining 4 boys reported continuous erection lasting over 11-12 h. All patients exhibited splenomegaly and massive leukocytosis (median WBC 470,000/µL, range 236,700-899,000). Interventions to treat priapism were unknown in 5 patients, and in the remaining cohort, comprised intravenous fluids ± heparin (n = 2), penile puncture (n = 5) ± injection of sympathomimetics (n = 4) ± intracavernous shunt operation (n = 1) paralleled by leukocyte-reductive measures. Management without penile puncture by leukapheresis or exchange transfusion was performed in 3 boys. In total, 7 out 15 (47%) long-term survivors (median age 20 years, range 19-25) responded to a questionnaire. All had maintained full erectile function; however, 5/7 had presented with stuttering priapism while in the remaining 2 patients priapism had lasted <12 h until intervention. At its extreme, low-flow priapism lasting for longer than 24 h may result in partial or total impotence by erectile dysfunction. This physical disability can exert a large psychological impact on patients' lives. In a narrative review fashion, we analyzed the literature on priapism in boys with CML which is by categorization stuttering or persisting as mostly painful, ischemic (low-flow) priapism. Details on the pathophysiology are discussed on the background of the different blood rheology of hyperleukocytosis in acute and chronic leukemias. In addition to the data collected, instructive case vignettes demonstrate the diagnostic and treatment approaches and the outcome of boys presenting with priapism. An algorithm for management of priapism in a stepwise fashion is presented. All approaches must be performed in parallel with cytoreductive treatment of leukostasis in CML which comprises leukapheresis and exchange transfusions ± cytotoxic chemotherapy.

"Vitreous Hemorrhage and Long-Lasting Priapism After COVID-19 m-RNA Based Vaccine: A Case Report". Eur J Ophthalmol 2023; 33:NP62-NP65. [PMID: 35505605 PMCID: PMC9080970 DOI: 10.1177/11206721221098880] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2021] [Accepted: 04/01/2022] [Indexed: 11/15/2022]
Abstract
PURPOSE To report a case of possible multi-district thromboembolic event involving the eye of a patient with several cardiovascular risk factors, following a second inoculation of SARS-CoV-2 m-RNA based vaccine. CASE-REPORT A 60-year-old man presented with blurred vision in the left eye lasting 1 month but started within 24 hours from the 2nd dose of BNT162b2 vaccine inoculation. He also reported a long-lasting but self-limiting priapism which started about 4 h after the vaccination. Patient's medical history included: acute lymphoblastic leukemia, treated with chemotherapy and HLA-identical sibling donor transplant 18 months earlier; subsequent cytomegalovirus posterior outer retinal necrosis (PORN) resolved with antiviral treatment; type II diabetes and erectile dysfunction. Ocular examination of the affected eye revealed vitreous hemorrhage which limited the observation of details of the fundus. After a 2-week follow-up without any clinical improvement, parsplana vitrectomy (PPV) with cataract extraction was performed. Surgical aspiration of a large preretinal hemorrhage revealed intraretinal flame-shaped hemorrhages and some cotton wool spots. Further intraoperative examination and post-operative fluorescein angiography excluded the rhegmatogenaous and the neovascular origin of the intraocular bleeding. CONCLUSIONS Due to the several predisposing factors such as diabetes, aspirin assumption, history of blood dyscrasia and infectious retinitis, the relationship between the acute intraocular bleeding and the BNT162b2 inoculation remains difficult to ascertain in this patient. However, the occurrence of lasting priapism and vitreous hemorrhage within 24 h from the vaccination is a critical event which deserves to be mentioned.

Management of Priapism: Results of a Nationwide Survey and Comparison with International Guidelines. UROLOGY RESEARCH & PRACTICE 2023; 49:225-232. [PMID: 37877823 PMCID: PMC10544432 DOI: 10.5152/tud.2023.22209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/27/2022] [Accepted: 04/06/2023] [Indexed: 10/26/2023]
Abstract
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.

Delayed placement of an inflatable penile prosthesis is associated with a high complication rate in men with a history of ischemic priapism. J Sex Med 2023; 20:1052-1056. [PMID: 37279440 DOI: 10.1093/jsxmed/qdad075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Revised: 05/03/2023] [Accepted: 05/05/2023] [Indexed: 06/08/2023]
Abstract
BACKGROUND Corporal fibrosis is known to result from prolonged priapism; however, the impact of the timing of penile prosthesis placement after priapism on complication rates is poorly understood. AIM We sought to evaluate the impact of timing of inflatable penile prosthesis (IPP) placement on complications in men with a history of ischemic priapism. METHODS We performed a multicenter, retrospective cohort study of patients with a history of priapism undergoing IPP placement by 10 experienced implantation surgeons. We defined early placement as ≤6 months from priapism to IPP. We identified a 1:1 propensity-matched group of men without a history of priapism and compared complication rates between men who had early placement, late placement, and no history of priapism. OUTCOMES Our primary outcome was postoperative noninfectious complications, and secondary outcomes included intraoperative complications and postoperative infection. RESULTS A total of 124 men were included in the study with a mean age of 50.3 ± 12.7 years. A total of 62 had a history of priapism and 62 were matched control subjects. The median duration of priapism was 37 (range, 3-168) hours and the median time from ischemic priapism to IPP placement was 15 months (range, 3 days to 23 years). Fifteen (24%) men underwent early (≤6 months) IPP placement at a median time of 2 months (range, 3 days to 6 months) following the ischemic priapism event. The remaining 47 (76%) underwent placement >6 months following priapism at a median time of 31.5 months (range, 7 months to 23 years). The complication rate in the delayed placement group was 40.5% compared with 0% in the early placement group and control group. Cylinder-related complications such as migration or leak accounted for 8 (57%) of 14 of the postoperative noninfectious complications. Full-sized cylinders were used in all patients who had a cylinder related complication. CLINICAL IMPLICATIONS Priapism patients should be referred to prosthetic experts early to decrease complication rates in those needing an IPP. STRENGTHS AND LIMITATIONS This is a multicenter study from experienced prosthetic urologists but is limited by the retrospective nature and small number of patients in the early placement group. CONCLUSION IPP complication rates are high in men with a history of ischemic priapism, especially when implantation is delayed beyond 6 months.

Treatment of Refractory Ischemic Priapism: A Case Report and Literature Review. Cureus 2023; 15:e39882.

Abstract
Recurrent priapism is a rare and poorly known entity. It is defined by recurrent episodes of painful erections that last less than four hours. The etiology is similar to that of ischemic priapism. Episodes lasting more than four hours require immediate intervention to prevent penile fibrosis and subsequent erectile dysfunction. A 42-year-old male with no significant chronic-degenerative history was referred to our medical center from his second-level medical unit after a 56-hour history of ischemic priapism with the persistence of tumescence despite medical and surgical treatment. Upon interrogation, the patient reported stuttering (recurrent) episodes of painful erections lasting approximately three to four hours, not associated with sexual activity or arousal, in the past two years, with spontaneous resolution. He denied the use of psychotropics or drugs for erectile dysfunction. As a palliative measure, a left saphenous-cavernous (Grayhack) bypass was performed, with a 90% decrease in tumescence and total resolution of pain during the first 12 hours. There is little information and treatment recommendations for patients with recurrent priapism, and even less for patients who are refractory to conventional medical and surgical treatment. Recurrent or stuttering priapism is a condition with a low incidence and a pathophysiology compatible with low-flow priapism. It is difficult to treat and has a poor prognosis in terms of erectile function. Likewise, it is mostly associated with the use of psychotropic drugs such as cocaine and marijuana, medications for erectile dysfunction such as phosphodiesterase inhibitors, prostaglandin E1 analogues, and hematological malignancies such as sickle cell anemia and multiple myeloma. The aim of this article is to share our experience with a patient refractory to multiple medical and surgical treatments.

Abstract
OBJECTIVE The development and initial clinical assessment of a novel 3D-printed procedural task trainer for the aspiration of penile corpus cavernosa in ischaemic priapism. METHODS A task trainer for the aspiration of penile corpus cavernosa was designed and manufactured using commercially available 3D printing equipment. The trainer was assessed in two separate training sessions led by faculty investigators. Participants in the sessions were asked to complete a post-procedure survey with regards to the utility and realism of the task trainer. RESULTS The participants (n = 14) covered a broad spectrum of clinician types. The trainer was perceived by the participants as being anatomically realistic, and especially while under drapes provided a reasonable facsimile of real clinical setup. The trainer proved resilient to multiple attempts at aspiration by multiple participants. CONCLUSIONS Participant and facilitator feedback indicates that the task trainer is a useful platform to train for what is a low frequency, but high stakes, procedure. Small numbers of participants preclude statistical rigour and certainty regarding overall performance of the trainer. However, the uniformity in the responses would suggest that this is indeed a task trainer that is 'fit for purpose'.

Abstract
BACKGROUND Priapism, a urologic emergency, has known associations with certain medical conditions. Many cases are idiopathic, suggesting an opportunity to identify novel risk factors. AIM We sought to identify medical conditions and pharmaceutical treatments that are associated with priapism using data-mining techniques. METHODS Using deidentified data in a large insurance claims database, we identified all men (age ≥20 years) with a diagnosis of priapism from 2003 to 2020 and matched them to cohorts of men with other diseases of male genitalia: erectile dysfunction, Peyronie disease, and premature ejaculation. All medical diagnoses and prescriptions used prior to first disease diagnosis were examined. Predictors were selected by random forest, and conditional multivariate logistic regressions were applied to assess the risks of each predictor. OUTCOMES We identified novel relationships of HIV and some HIV treatments with priapism and confirmed existing associations. RESULTS An overall 10 459 men with priapism were identified and matched 1:1 to the 3 control groups. After multivariable adjustment, men with priapism had high associations of hereditary anemias (odds ratio [OR], 3.99; 95% CI, 2.73-5.82), use of vasodilating agents (OR, 2.45; 95% CI, 2.01-2.98), use of HIV medications (OR, 1.95; 95% CI, 1.36-2.79), and use of antipsychotic medications (OR, 1.90; 95% CI, 1.52-2.38) as compared with erectile dysfunction controls. Similar patterns were noted when compared with premature ejaculation and Peyronie disease controls. CLINICAL IMPLICATIONS HIV and its treatment are associated with priapism, which may affect patient counseling. STRENGTHS AND LIMITATIONS To our knowledge, this is the first study to identify risk factors for priapism utilizing machine learning. All men in our series were commercially insured, which limits the generalizability of our findings. CONCLUSION Using data-mining techniques, we confirmed existing associations with priapism (eg, hemolytic anemias, antipsychotics) and identified novel relationships (eg, HIV disease and treatment).

Abstract
OBJECTIVE Penile prosthesis implantation in scarred corporal bodies is one of the most challenging urologic procedures, with high risks of perforation and/or failure. We present Shaeer's Cavernotome (patent application number PCT/EG2021/050003). This is the forward-cutting cavernotome that relies on the principle of controlled coring and grinding rather than forward stabbing, with fibrous tissue accommodated into the hollow core, thereby ensuring high efficacy and low risk of perforation. MATERIALS AND METHODS This is a prospective study involving 18 patients with severe corporal scarring. Surgery is performed through a peno-scrotal incision with an indwelling urethral catheter. Corporotomies are incised and a 2-cm-long core of fibrous tissue is excised with a scalpel. Shaeer's Cavernotome is introduced and lodged against the fibrous tissue. Coring proceeds with the stretched corpus or crus held between the thumb and index fingers of the non-dominant hand as a guide, ahead of the tip. Shaeer's cavernotome doubles as a sizer. Following coring, penile prosthesis implantation proceeds. RESULTS Dilation of the corpora cavernosa was successful in 17 out of 18 patients. Average coring time was 8 ± 3.2 minutes. Dilation was up to girth 13 Hegar in 12 patients, and 11 in 5. No perforations or infections were encountered. CONCLUSION Shaeer's cavernotome facilitates penile prosthesis implantation in scarred corporal bodies. Full excavation of both corpora cavernosa is achievable in less than 10 minutes, with a low risk for perforation.

Priapism in a Patient with Rectal Adenocarcinoma. Diseases 2023; 11:diseases11010034.

Abstract
BACKGROUND Priapism is a very rare complication of malignancy and is usually accompanied by locally advanced or widely metastatic disease. We describe a case of priapism arising in a 46-year-old male with localised rectal cancer that was responding to therapy. CASE PRESENTATION This patient had just completed two weeks of neoadjuvant, long-course chemoradiation when he presented with persistent painful penile erection. Assessment and diagnosis were delayed for more than 60 h, and although a cause could not be determined from imaging, a near complete radiological response of the primary rectal cancer was seen. His symptoms were refractory to urologic intervention and were associated with extreme psychological distress. He re-presented shortly thereafter with extensively metastatic disease in the lungs, liver, pelvis, scrotum, and penis; additionally, multiple venous thromboses were identified, including in the dorsal penile veins. His priapism was not reversible and was associated with a considerable symptom burden for the remainder of his life. His malignancy did not respond to first-line palliative chemotherapy or radiation, and his clinical course was further complicated by obstructive nephropathy, ileus, and genital skin breakdown with a suspected infection. We initiated comfort measures, and he ultimately died in hospital less than five months after his initial presentation. CONCLUSION Priapism in cancer is usually related to tumour infiltration of the penis and corporal bodies resulting in poor venous and lymphatic drainage. The management is palliative and can include chemotherapy, radiation, surgical shunting, and potentially penectomy; however, conservative penis-sparing therapy may be reasonable in patients with limited life expectancy.

Abstract
PURPOSE The following case report discusses probable clitoral priapism secondary to duloxetine and pregabalin. While this is a rare adverse effect, it is possible given the mechanism of action and potentiating effects of the combined therapy. This adverse drug reaction was reported to MedWatch and shows that additional research into the physiology of clitoral erection is warranted given the scarcity of information on how drugs influence this reaction. SUMMARY A 53-year-old African American female with uncontrolled anxiety was started on duloxetine. Pregabalin was added 1 month later due to continued feelings of anxiety. Three weeks later, the patient reported symptoms of clitoral pain, as well as a swollen, tender, and erect clitoris. These adverse effects remained for 4 days, prompting the patient to present to the emergency department where a physical exam was completed with no significant finding except as noted above. Pregabalin was immediately discontinued by the attending physician based on the probability that the swelling was likely drug-induced clitoral priapism. During follow-up, the patient continued to note clitoral erection and pain. The psychiatric pharmacist tapered off duloxetine over 2 weeks with resolution of symptoms. In an examination of the mechanism of action of both drugs, pregabalin can amplify duloxetine's inhibitory effects on voltage-dependent calcium channels. It is likely this mechanism that causes smooth muscle relaxation and led to clitoral priapism. CONCLUSION This case suggests that pharmacological agents affecting vasoconstriction through serotonergic receptors or calcium-dependent channels can also influence clitoral erection.

Abstract
PURPOSE Priapism is a debilitating condition that affects sexual function. As a majority of cases are idiopathic, investigators have hypothesized underlying vascular dysfunction which may predispose men to priapism. We sought to determine if men are at risk for other sequelae of vascular dysfunction such as cardiovascular and thromboembolic disease after a priapism event. MATERIALS AND METHODS Using a large commercial insurance claims data warehouse, we evaluated all men (age ≥20) with a diagnosis of priapism from 2003-2020 and matched them to a cohort of men with other urological disorders of sexual dysfunction (erectile dysfunction, Peyronie's disease, and premature ejaculation). We identified incident disease (cardiovascular disease, heart disease, embolism, thrombosis, cerebrovascular disease) for all cohorts. RESULTS A total of 10,459 men with priapism were identified and were matched to men with erectile dysfunction, Peyronie's disease, or premature ejaculation. The mean age was 51.1 years old. Men with priapism showed increased incidence of heart disease, both ischemic (HR 1.24, 95% CI 1.09-1.42) and other heart disease (HR 1.24, 95% CI 1.12-1.38) in the years following the priapism diagnosis. Incident cerebrovascular disease was also more likely in men with a history of priapism (HR 1.33, 95% CI 1.15-1.55). Men requiring treatment for ischemic priapism had a higher hazard of cardiovascular and cerebrovascular disease. In addition, men with more priapism episodes had a higher rate of cardiovascular disease and thromboembolic events. CONCLUSIONS Men with priapism are at increased risk for cardiovascular and cerebrovascular events in the years following a priapism.

Abstract
Priapism, an unwanted, painful, prolonged erection that is unrelated to sexual stimulation, is a common complication of sickle cell disease (SCD). Priapic events in SCD are stuttering, meaning they occur repeatedly with intervening periods of detumescence. Without health care intervention, repeated episodes can lead to erectile dysfunction. There are limited treatment options for SCD-related priapism and no approved targeted therapies. Crizanlizumab is a monoclonal antibody that binds to P-selectin and is used to reduce the frequency of vaso-occlusive crises in patients with SCD. Here, we report the cases of 3 patients with SCD-related priapism who were treated with crizanlizumab. All patients were African American men who experienced numerous priapic episodes that interfered with their daily lives. Upon treatment with crizanlizumab, priapic events were reduced in all 3 patients. These successful cases suggest a potential role for crizanlizumab in the prevention of SCD-related priapism.

Abstract
Priapism is one of the most common urologic emergencies and is characterized by a prolonged and painful erectile state unrelated to sexual stimulation or sexual desire. Neoplasm-associated priapism is a rare condition and is usually caused by corporeal metastases of other pelvic area malignancies. Primary penile malignancy-related malignant priapism is extremely rare. In this reported case, an 82-year-old male presented with priapism. The penile doppler ultrasound and pelvic magnetic resonance imaging were compatible with ischemic priapism and corporal mass. Subsequently, the patient underwent total penectomy and bilateral superficial inguinal lymphadenectomy. The pathology report was consistent with primary penile squamous cell cancer (SCC), so the patient underwent adjuvant radiotherapy. However, he developed multiple metastases and could survive for about six months. The patient had undergone radical cystectomy (RC) and urethrectomy 19 and 2 years ago due to urothelial carcinoma, respectively. To the best of our knowledge, this is the second case of malignant priapism due to primary penile SCC and represents one of the longest urethral recurrence periods after RC. When a patient presents with malignant priapism, primary penile malignancies should be considered in differential diagnosis, even if the patient has a history of pelvic area malignancies.

The value of leukapheresis for treatment of priapism as presenting feature of chronic myeloid leukemia-Case report and review of literature. EJHAEM 2022; 3:1100-1115. [PMID: 36467799 PMCID: PMC9713041 DOI: 10.1002/jha2.545] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Revised: 06/28/2022] [Accepted: 07/05/2022] [Indexed: 06/17/2023]
Abstract
Priapism is a rare presenting feature of chronic myeloid leukemia (CML) in male patients. Treatment aims to relieve symptoms and to prevent erectile dysfunction. Several treatment modalities exist, however no standard treatment is recommended. We evaluated literature concerning different treatment approaches and evaluate the value of leukapheresis in treatment of priapism. The literature search resulted in 57 included articles, consisting of 53 studied patients. Patients had a mean age of 25.3 years, average time from onset to presentation at the hospital was 2 days, and mean white blood cell (WBC) count was 344 × 109/L. Most patients (67.9%) were treated with a combined approach (different modalities were radiological, urological, and oncological treatment). Twelve patients, with a mean WBC count of 365 × 109/L, received leukapheresis. Only two of them reported erectile dysfunction after treatment. Priapism is an urological emergency requiring urgent multidisciplinary treatment. We highlight the importance of local urological therapy combined with systemic therapy for CML. Therapeutic leukapheresis should be applied when available and with no other contraindications.

Abstract
OBJECTIVE To describe two cases of man with the diagnosis of ischemic priapism after the intake of tamsulosin and to revise the scientific literature. METHODS We present two cases of men that developed an ischemic priapism after the intake of tamsulosin prescribed for STUI and were treated in our hospital. We described the two cases, from the diagnosis until the surgery that was performed. Also, we review the scientific literature about this topic. RESULTS In one hand, a 67 years old man with the previous diagnosis of diabetes mellitus, hypertension and dyslipidemia that take a one single dosis of tamsulosin and developed a priapism of 9 hours of duration. He was diagnosticated of low-flow priapism that was reverted after the use of intracavernosal phenylephrine. On the other hand, a 61 years old man without any medical condition. He developed a priapism after the intake of also one single dosis of tamsulosin and came to the hospital after 48 hours of the beginning of the erection. In this case, the use of intracavernosal phenylephrine wasn´t effective so we decided to performed a distal shunt between cavernosal and spongy body according to the techniques of Winter, Ebbehoj and Al-Ghorab. All of them without results. At the end, we tried a proximal shunt according Quackles technique, also ineffective. The patient declined another surgery for implantation of a pennis prothesis and went home after four days of hospitalization with the disappearance of the pain. CONCLUSIONS The tamsulosin is a drug well known by urologist that have a safety profile probed with the years. Nevertheless, it's association with a disease like the priapism forced us to explain to our patients this rare adverse effect.

Abstract
INTRODUCTION Priapism is a compartment syndrome, defined as an unwanted penile erection lasting longer than four hours, unrelated to sexual stimulation, and persistent even after ejaculation/orgasm. Ischemic priapism is considered a urologic emergency requiring time-sensitive management. Studies have documented that untreated priapism is associated with progressive ischemic histological changes in the corpora cavernosa, such as widespread smooth muscle necrosis, blood vessel and nerve attrition, and trabecular fibrosis. Treatment options include conservative management, corporal irrigation, pharmacologic therapy, and surgery. We herein provide an overview of the emergency pharmacology for priapism. AREAS COVERED The American Urological Association (AUA) and the European Association of Urology (EAU) both recommend penile aspiration in conjunction with intracavernosal injection of sympathomimetics as the initial management of ischemic priapism. We have performed a retrospective review of the literature from 1914 to 2022 by using PubMed and a review of the treatment guidelines from the AUA and the EAU to discuss the various therapies for ischemic priapism in the emergent setting. EXPERT OPINION After a thorough overview of the literature regarding the treatment of ischemic priapism in the emergent setting, we conclude that intracavernosal phenylephrine is superior to other agents due to its demonstrated efficacy and limited systemic side effects.

Getting the diagnosis of priapism wrong; when not to aspirate. Andrologia 2022; 54:e14505. [PMID: 35747930 DOI: 10.1111/and.14505] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2022] [Revised: 05/22/2022] [Accepted: 05/25/2022] [Indexed: 11/26/2022] Open
Abstract
Priapism is defined as a full or partial erection lasting greater than 4 h due to a fault in the normal detumescence mechanism of the penis. We describe the case of a confused 73-year-old gentleman presenting with painless priapism, a 2 cm non-tethered lesion in the scrotum and a vague palpable pelvic mass. On the presumption that this was a case of high-flow non-ischaemic priapism secondary to pelvic malignancy, the urology registrar attempted corporal body aspiration. Clear fluid was aspirated and the penis became flaccid instantly. A CT scan performed to determine the presence of a pelvic mass, revealed a penile prosthesis and artificial reservoir. While iatrogenic penile prosthesis malfunctions are well established in the literature, a case managed as an acute priapism is yet to be reported. This case teaches us the importance of taking an adequate medical history and clinical examination prior to formulating a diagnosis and administering treatment.

Priapism caused by partial deficiency of tetrahydrobiopterin through hypofunction of the sympathetic neurons in sepiapterin reductase gene-disrupted mice. J Inherit Metab Dis 2022; 45:621-634.

Abstract
6R-L-erythro-5,6,7,8-tetrahydrobiopterin (BH4) is an essential cofactor for aromatic L-amino acid hydroxylases, including tyrosine hydroxylase (TH), alkylglycerol monooxygenase, and three types of nitric oxide (NO) synthases (NOS). Sepiapterin reductase (SPR) catalyzes the third step of BH4 biosynthesis. SPR gene-disrupted (Spr-/- ) mice exhibit a dystonic posture, low body weight, hyperphenylalaninemia, and unstable hypertension with endothelial dysfunction. In this study, we found that Spr-/- mice suffered from a high incidence of severe priapism. Their erections persisted for months. The biopterin, BH4, and norepinephrine contents, and TH protein levels in the penile tissue of Spr-/- mice without and with priapism were significantly reduced compared to those of Spr+/+ mice. In contrast, their neural NOS (nNOS) protein levels were increased, and the cyclic guanosine monophosphate (cGMP) levels were remarkably elevated in the penises of Spr-/- mice with priapism. The symptoms were relieved by repeated administration of BH4. The biopterin, BH4, and norepinephrine contents were increased in penile homogenates from BH4-supplemented Spr-/- mice, and the TH protein levels tended to increase, and their nitrite plus nitrate levels were significantly lower than those of vehicle-treated Spr-/- mice and were approximately the same as vehicle- and BH4-supplemented Spr+/+ mice. Thus, we deduced that the priapism of Spr-/- mice is primarily caused by hypofunction of the sympathetic neurons due to cofactor depletion and the loss of TH protein and, further, dysregulation of the NO/cGMP signaling pathway, which would be caused by disinhibition of nNOS-containing neurons and/or abnormal catabolism of cyclic nucleotides is suggested.

Abstract
Priapism in chronic myeloid leukemia (CML) appears to be an infrequent manifestation as well as a crucial emergency. Here, we report an 18-year-old male presenting with a persistent erection of the penis for 20 days. We evaluated and compared the reported cases within 20 years discussing the management of priapism in CML. Cytoreductive therapy followed by leukapheresis, the administration of tyrosine kinase inhibitor, and intra-cavernosal blood aspiration may resolve the symptoms of priapism. Early intervention for cytoreduction and aspiration are the pivotal keys to successfully impeding the complications.

Tamsulosin and risk of priapism: A causality assessment using Austin Bradford Hill Criteria. Pharmacol Res Perspect 2022; 10:e00934.

Abstract
Tamsulosin hydrochloride, a selective alpha-adrenergic blocking agent has been previously associated with priapism. Priapism is a medically serious condition that, if not intervened, can cause permanent erectile dysfunction. This study was conducted to investigate whether the association of tamsulosin and priapism is causal. All currently available evidence such as experimental, biological, toxicological, published studies, and safety data mined from the WHO global pharmacovigilance database was systematically organized into the Austin Bradford Hill causality assessment framework. In the international pharmacovigilance database, a strong association between tamsulosin and priapism (IC025 = 4.1; PRR025 = 19.9; ROR025 = 20) was observed. There were 122 cases of priapism associated with tamsulosin submitted to the database from 23 countries. In 87.7% of the cases, tamsulosin was reported as a 'sole suspect,' and in 50.8%, it was the only drug administered. In several patients, priapism resolved following discontinuation of tamsulosin and recurred after its reintroduction. Both in the published and unpublished data, for majority of the cases, the time to onset of priapism was within few days following the first intake of tamsulosin. Cases of priapism, particularly those published, were consistent in their clinical features with patients experiencing prolonged painful erection that required aspiration of cavernosal blood, irrigation of the corpora cavernosa, and treatment with vasopressors. Other alpha-adrenergic blocking agents that are structurally analogous with tamsulosin have also been associated with priapism. In several cases, tamsulosin was used off-label, for the treatment of ureteral calculi expulsion. Eight patients experienced priapism that ended up with serious complications such as ejaculation disorders and erectile dysfunction. The currently available totality of evidence suggests that the association of tamsulosin and priapism is causal. Healthcare professionals are therefore recommended to cautiously prescribe tamsulosin and ensure that consumers are aware of the potential risk of priapism.

Abstract
BACKGROUND Priapism is a rare condition in children and the treatment algorithm is controversial in this age group. Herein, we report eight cases with low-flow priapism and our stepwise treatment approach in light of literature. METHODS We present a simple stepwise treatment for low-flow priapism including five steps. Step 1: Cold compress and analgesia while evaluation the priapism and its etiology. Step 2: Corporal aspiration and adrenaline infusion in the ward. Step 3: Modified Winter shunt in the same place. Step 4: Ketamine application and caudal block in the operating room. Step 5: Sapheno-cavernous (Grayhack) shunt. Eight cases with low-flow priapism were reviewed retrospectively. Symptoms, duration of tumescence, the interventions, and step that provide detumescence were recorded. RESULTS The mean age of patients was 8.5 years (1-17 y). The median time of the priapism before admission was 15 h (4-165 h). The etiological factors were sickle cell disease, hemodialysis due to chronic renal failure, and factor V Leiden mutation in three patients. Detumescence was achieved in one patient at Step 2, in two patients at Steps 3, 4, and 5, respectively. Rigidity of cavernous body was observed in one patient in long-term follow-up. CONCLUSION Low-flow priapism is a urological emergency that may cause erectile dysfunction. Treatment options should be selected according to a protocol that prevents time loss and avoids more invasive treatment in unnecessary situations. Our algorithm with simple nature and its steps from less invasive to more invasive procedures may be an alternative for the treatment of low-flow priapism.

Abstract
BACKGROUND Urological involvement is rare in patients with coronavirus disease 2019 (COVID-19). Priapism, one of the urological involvements, was reported as one of the COVID-19 comorbidities in the elderly male patient group but has rarely been reported in the pediatric age group. CASE Herein, a previously healthy 8-year-old patient with COVID-19-associated priapism, which is rare in children, is presented. CONCLUSIONS During the pandemic, in pediatric cases with priapism of unknown etiology, COVID-19 should be one of the diagnoses to be considered.

Abstract
Priapism is a rare pathological condition defined as painful and persistent penile erection that is unrelated to sexual stimulation. It can be classified as ischaemic or non-ischaemic. Many causes have been attributed to ischaemic priapism, including the use of some medications such as antipsychotics. The mechanism of priapism associated with antipsychotics is thought to be related to alpha-adrenergic blockage that is mediated by the alpha receptors in the corpora cavernosa of the penis. In this paper, we describe a case of a patient who suffered from Risperidone-induced priapism, and how this adverse effect was resolved by switching to olanzapine followed by olanzapine pamoate. A literature search on PubMed/Medline up to 2011 was conducted by some doctors from London and found 30 cases of priapism associated with risperidone. Based on this work, we searched PubMed through 2021, using the keywords 'priapism' and 'risperidone' and found a total of 43 cases of priapism involving risperidone. Priapism is not correlated with the dosage of this psychotropic drug, and has also occasionally occurred when risperidone has been used in conjunction with another drug. The question of choosing a replacement antipsychotic after the first one has induced priapism, remains problematic. It would be preferable to switch to a drug with less marked alpha1-blocking properties, but no consensus has been reached as to the best choice of medication. Finally, any prescription of an antipsychotic treatment must be preceded by a careful interrogation in search of risk factors for priapism, and the patient should be made aware of the possible occurrence of this side effect and the need to then seek urgent medical advice.

Abstract
Purpose Penile research is expected to reveal new targets for treatment and prevention of the complex mechanisms of its disorder including erectile dysfunction (ED). Thus, analyses of the molecular processes of penile ED and continuous erection as priapism are essential issues of reproductive medicine. Methods By performing mouse N‐ethyl‐N‐nitrosourea mutagenesis and exome sequencing, we established a novel mouse line displaying protruded genitalia phenotype (PGP; priapism‐like phenotype) and identified a novel Pitpna gene mutation for PGP. Extensive histological analyses on the Pitpna mutant and intracavernous pressure measurement (ICP) and liquid chromatography–electrospray ionization tandem mass spectrometry (LC–ESI/MS)/MS analyses were performed. Results We evaluated the role of phospholipids during erection for the first time and showed the mutants of inducible phenotypes of priapism. Moreover, quantitative analysis using LC–ESI/MS/MS revealed that the level of phosphatidylinositol (PI) was significantly lower in the mutant penile samples. These results imply that PI may contribute to penile erection by PITPα. Conclusions Our findings suggest that the current mutant is a mouse model for priapism and abnormalities in PI signaling pathways through PITPα may lead to priapism providing an attractive novel therapeutic target in its treatment.

Abstract
We report the case of a patient who was initially presented with ischemic priapism to the emergency department. He was treated with adrenaline intracavernous injections and aspiration with irrigation of the corpora cavernosa and distal shunt. In the postoperative period, anemia, basophilia, eosinophilia, thrombocytosis and hyperleukocytosis were detected. The patient was subsequently diagnosed with chronic myeloid leukemia. Priapism is a rare manifestation of chronic myeloid leukemia (≤ 3%) and occurs mostly due to hyperleukocytosis, resulting in thrombus formation and corporal venous outflow obstruction. Priapism occurring in any setting is considered as a medical emergency that requires immediate local therapy because of resulting irreversible cell damage and fibrosis if not treated within the first 24-48 h.

Abstract
Malignant priapism is a condition of painful induration and erection of the penis secondary to metastatic infiltration by a neoplasm. This condition is associated with a poor prognosis. We report on a case of an 87-year-old man who presented with a painful, partially erected penis subsequent to a diagnosis of metastatic Gleason 4+5 prostate cancer. Magnetic resonance imaging (MRI) showed diffuse bilateral infiltration of his corpora cavernosa. The core biopsy of the penile nodule revealed it to be a poorly differentiated carcinoma consistent with prostatic origin. The patient's symptoms were completely resolved after treatment with high-dose palliative conformal radiotherapy (40Gy in 16 fractions). We systemically reviewed clinical reports of palliative radiotherapy for malignant priapism with the aim to gain more information on the management of this rare condition.

Abstract
High-flow priapism is a rare condition characterized by prolonged and painless erection. It is defined as contusion or thrombosis of the cavernous body of the penis usually secondary to blunt trauma. Due to the rarity of the disease, there is no well-defined consensus about treatment. Conservative treatment is often applied with non-steroidal anti-inflammatory drug. We present a case of 58-year-old man with proximal partial priapism that developed secondary to blunt trauma to the penis. The patient did not benefit from non-steroidal anti-inflammatory drug therapy and then was successfully treated with selective embolization.

Thalassemia is a hematologic disorder caused by genetic mutation resulting in impaired hemoglobin chain production. Patients with thalassemia commonly experience complications such as anemia, blood transfusion-related issues, hepatic or cardiac involvement, and psychosocial impacts. Rarely, priapism has been associated with thalassemia as an initial presentation or subsequently occurring at any time in the disease course. Our literature review summarizes the reported cases of thalassemia-associated priapism and delves into underlying mechanisms of its pathophysiology and appropriate management.

Chronic myeloid leukemia (CML) is predominantly a disease of adults and the elderly. CML is uncommon in the paediatric age. Priapism as an initial presentation is quite uncommon in CML and is rare in the case of CML in paediatric and adolescent age. We present a case of CML in an adolescent male who presented with priapism of 48 hours duration. The patient was managed in an emergency by corporal aspiration and saline irrigation and was found to have CML during a hospital stay. The patient was treated with imatinib and is under follow-up for the last two years.

Abstract
Interventional radiology of the male urogenital system includes percutaneous and endovascular procedures, and these last consist mostly of transcatheter arterial embolizations. At the kidney level, arterial embolizations are performed mainly for palliative treatment of parenchymal tumors, for renal traumas and, less frequently, for arteriovenous fistulas and renal aneurysms and pseudoaneurysms. These latter may often require emergency intervention as they can cause renal or peri-renal hematomas or significant hematuria. Transcatheter arterial embolization is also an effective therapy for intractable severe bladder hematuria secondary to a number of neoplastic and inflammatory conditions in the pelvis, including unresectable bladder cancer and radiation-induced or cyclophosphamide-induced hemorrhagic cystitis. Endovascular interventional procedures for the penis are indicated for the treatment of post-traumatic priapism. In this article, we review the main endovascular radiological interventions of the male urogenital system, describing the technical aspects, results, and complications of each procedure at the various anatomical districts.

Abstract
Priapism is described as a persistent and non-sexual erection. It is a rare presenting complaint with a wide range of aetiologies. Malignant priapism was first used to describe persistent erections secondary to neoplastic infiltration of the penis by Peacock in 1938.
