Contemporary management of ischemic priapism: A 12-year population-based analysis from a large US database. Andrology 2024. [PMID: 39142706 DOI: 10.1111/andr.13740] [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: 05/12/2024] [Revised: 07/08/2024] [Accepted: 08/05/2024] [Indexed: 08/16/2024]
Abstract
BACKGROUND Priapism is a urological condition characterized by a persistent erection. The management varies based on its subclassifications. Despite established clinical guidelines for ischemic priapism, there is a lack of large-scale research focused on patient characteristics and management strategies. OBJECTIVES To analyze the contemporary management of ischemic priapism in the US, exploring patient demographics and clinical characteristics, as well as predictors of erectile dysfunction (ED) and penile prosthesis implantation (PPI). MATERIALS AND METHODS We performed a retrospective analysis of the PearlDiver Mariner database, reviewing records from 2010-2021. Adult males diagnosed with ischemic priapism were included. Data analysis covered demographic, clinical variables, and management strategies. Predictors of de novo ED and PPI were evaluated using multivariable logistic regression analysis. RESULTS Of 36,120 patients, most (93%) received only medical management, and a minority underwent surgical interventions (penile shunt surgery [PSS], PPI or both). Medical management was typically effective, as 67.08% of the patients in this group experienced only one episode of priapism. However, de novo ED occurred in 16.57% of these patients. The majority of patients undergoing PPI had an inflatable prosthesis (81%). Older age (odds ratio, OR 1.02), the presence of metabolic diseases (OR 1.39), neurogenic disorders (OR 1.72), solid pelvic malignancies (OR 1.09), and multiple episodes of priapism were identified as significant predictors of de novo ED (all p < 0.05). Similarly, age (OR 1.03), the presence of metabolic diseases (OR 1.23), solid pelvic malignancies (OR 1.99), and multiple episodes of priapism were associated with higher likelihood of PPI (all p < 0.05). CONCLUSION Most cases of ischemic priapism are managed with the medical therapy. Less than 3% of patients with ischemic priapism receive PPI, and when this occurs an inflatable prosthesis is favored. Age, specific comorbidities, and multiple episodes of priapism appear to be significant predictors of ED and PPI.

Cases of Patients Treated in Countries With Limited Resources and Discussed by Experts of the International CML Foundation (iCMLf)-Case No. 1: A Boy Presenting With Priapism and Loss of Vision. Case Rep Oncol Med 2024; 2024:5534445. [PMID: 39104564 PMCID: PMC11300043 DOI: 10.1155/2024/5534445] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 04/03/2024] [Accepted: 04/10/2024] [Indexed: 08/07/2024] Open
Abstract
Pediatric chronic myeloid leukemia (pCML) is a rare malignancy accounting for only 2%-3% of all childhood leukemias. Due to this rarity, familiarity with pCML is limited among most pediatric practitioners, including even pediatric hemato-oncologists. In low- and middle-income countries (LMICs), limited financial resources and limited data specific to pCML represent obstacles that healthcare providers must face in diagnosing and treating this rare condition in children. The International CML Foundation (iCMLf) is improving outcomes for people with CML in these countries where resources, diagnostics, and access to medicines may be limited (https://www.cml-foundation.org/lmic-programs.html). Virtual meetings with the purpose of teaching participating pediatricians from LMICs of defined geographical regions were organised by the iCMLf in 2023. At a virtual meeting of the South Asia region, the case of a 14-year-old Indian boy was presented diagnosed with CML in a chronic phase complicated by priapism and loss of vision in his left eye due to hyperleukocytosis. Key aspects of this case are discussed in-depth from the perspective of (i) a pediatric hemato-oncologist practicing in a high-income country, (ii) a pediatric hemato-oncologist practicing in a LMIC, (iii) an adult CML hematologist, and (iv) from the iCMLf in improving the care of children with CML worldwide. Thus by discussing a multifaceted complicated case of pCML in written form as well as pointing to the pediatric module of the iCMLf Knowledge Centre will hopefully contribute to minimize existing knowledge gaps in a rare pediatric malignancy.

Abstract
Penile MRI is a vital yet underutilized diagnostic tool that provides detailed information crucial for managing various penile pathologies. Due to its infrequent use, many radiology trainees lack confidence in interpreting these exams. This article reviews the anatomy, key technical considerations, and interpretive pearls for penile trauma, Peyronie's disease, priapism, penile neoplasms, prosthesis evaluation, and a few miscellaneous conditions. Through illustrative case examples, this review aims to enhance the understanding and proficiency of radiologists in performing and interpreting penile MRI in these clinical scenarios.

Abstract
Patients with sickle cell disease (SCD) display priapism, a prolonged penile erection in the absence of sexual arousal. The current pharmacological treatments for SCD-associated priapism are limited and focused on acute interventions rather than prevention. Thus, there is an urgent need for new drug targets and preventive pharmacological therapies for this condition. This review focuses on the molecular mechanisms linked to the dysfunction of the NO-cyclic guanosine monophosphate (cGMP)-phosphodiesterase type 5 (PDE5) pathway implicated in SCD-associated priapism. In murine models of SCD, reduced nitric oxide (NO)-cGMP bioavailability in the corpus cavernosum is associated with elevated plasma hemoglobin levels, increased reactive oxygen species levels that inactive NO, and testosterone deficiency that leads to endothelial nitric oxide synthase downregulation. We discuss the consequences of the reduced cGMP-dependent PDE5 activity in response to these molecular changes, highlighting it as the primary pathophysiological mechanism leading to excessive corpus cavernosum relaxation, culminating in priapism. We also further discuss the impact of intravascular hemolysis on therapeutic approaches, present current pharmacological strategies targeting the NO-cGMP-PDE5 pathway in the penis, and identify potential pharmacological targets for future priapism therapies. In men with SCD and priapism, PDE5 inhibitor therapy and testosterone replacement have shown promising results. Recent preclinical research reported the beneficial effect of treatment with haptoglobin and NO donors. SIGNIFICANCE STATEMENT: This review discusses the molecular changes that reduce NO-cGMP bioavailability in the penis in SCD and highlights pharmacological targets and therapeutic strategies for the treatment of priapism, including PDE5 inhibitors, hormonal modulators, NO donors, hydroxyurea, soluble guanylate cyclase stimulators, haptoglobin, hemopexin, and antioxidants.

Abstract
INTRODUCTION Although oral phosphodiesterase 5 inhibitors represent a first choice and long-term option for about half of all patients with erectile dysfunction (ED), self-injection therapy with vasoactive drugs remains a viable alternative for all those who are not reacting or cannot tolerate oral drug therapy. This current injection therapy has an interesting history beginning in 1982. OBJECTIVES To provide a comprehensive history of self-injection therapy from the very beginnings in 1982 by contemporary witnesses and some members of the International Society for Sexual Medicine's History Committee, a complete history of injection therapy is prepared from eyewitness accounts and review of the published literature on the subject, as well as an update of the current status of self-injection therapy. METHODS Published data on injection therapy, as a diagnostic and therapeutic tool for ED, were reviewed thoroughly by PubMed and Medline research from 1982 until June 2023. Early pioneers and witnesses added firsthand details to this historical review. Therapeutic reports of injection therapy were reviewed, and results of side effects and complications were thoroughly reviewed. RESULTS The pioneers of the first hours were Ronal Virag (1982) for papaverine, Giles Brindley (1983) for cavernosal alpha-blockade (phentolamine and phenoxybenzamine), Adrian Zorgniotti (1985) for papaverine/phentolamine, and Ganesan Adaikan and N. Ishii (1986) for prostaglandin E1. Moxisylyte (thymoxamine) was originally marketed but later withdrawn. The most common side effect is priapism, with the greatest risk of this from papaverine, which has modified its use for therapy. Currently, prostaglandin E1 and trimixes continue to be the agents of choice for diagnostic and therapeutic use in ED. A recent agent is a mixture of a vasoactive intestinal polypeptide (aviptadil) and phentolamine. CONCLUSIONS After 40 years, self-injection therapy represents the medication with the highest efficacy and reliability rates and remains a viable option for many couples with ED. The history of this therapy is rich.

Abstract
Priapism, defined as a prolonged and often painful penile erection occurring without sexual stimulation or desire, is a common complication in sickle cell disease (SCD), affecting up to 48% of male patients. This condition presents significant clinical challenges and can lead to erectile dysfunction if not properly managed. Current pharmacological treatments for SCD-related priapism are primarily reactive rather than preventative, highlighting a gap in effective medical intervention strategies. A critical factor in developing priapism is the reduced basal bioavailability of nitric oxide (NO) and cyclic guanosine monophosphate (cGMP) in erectile tissues. New prevention strategies should ideally target the underlying pathophysiology of the disease. Compounds that stimulate and activate soluble guanylate cyclase (sGC) emerge as potential therapeutic candidates since these compounds have the property of inducing cGMP production by sGC. This review explores the potential of sGC stimulators and activators in treating priapism associated with SCD. We discuss the advantages of these agents in the face of the challenging pathophysiology of SCD. Additionally, the review underscores the impact of intravascular hemolysis and oxidative stress on priapism pathophysiology in SCD, areas in which sGC stimulators and activators may also have beneficial therapeutic effects.

Abstract
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.

Abstract
A range of drugs have a direct role in triggering ischaemic priapism. We aimed at identifying: a) which medications are associated with most priapism-reports; and, b) within these medications, comparing their potential to elicit priapism through a disproportionality analysis. The FDA Adverse Event Reporting System (FAERS) database was queried to identify those drugs associated the most with priapism reports over the last 5 years. Only those drugs being associated with a minimum of 30 priapism reports were considered. The Proportional Reporting Ratios (PRRs), and their 95% confidence intervals were computed. Out of the whole 2015-2020 database, 1233 priapism reports were identified, 933 of which (75.7%) were associated with 11 medications with a minimum of 30 priapism-reports each. Trazodone, olanzapine and tadalafil showed levels of disproportionate reporting, with a PRR of 9.04 (CI95%: 7.73-10.58), 1.55 (CI95%: 1.27-1.89), and 1.42 (CI95%: 1.10-1.43), respectively. Most (57.5%) of the reports associated with the phosphodiesterase type 5 inhibitors (PDE5Is) were related with concomitant priapism-eliciting drugs taken at the same time and/or inappropriate intake/excessive dosage. Patients taking trazodone and/or antipsychotics need to be aware of the priapism-risk; awareness among prescribers would help in reducing priapism-related detrimental sequelae; PDE5I-intake is not responsible for priapism by itself, when appropriate medical supervision is provided.

Heme-induced corpus cavernosum relaxation and its implications for priapism in sickle cell disease: a mechanistic insight. Andrology 2024.

Abstract
BACKGROUND Patients with sickle cell disease (SCD) experience intravascular hemolysis, leading to elevated plasma heme levels. This phenomenon has been associated with increased priapism in men with SCD. The heme group can be metabolized by heme oxygenase (HO), generating carbon monoxide (CO), which is known to promote smooth muscle relaxation via soluble guanylyl cyclase (sGC)-cyclic guanosine monophosphate (cGMP). However, the effects of heme on the relaxation responses of corpus cavernosum (CC) have not been investigated. OBJECTIVES To evaluate the functional and biochemical effects of the heme group on mouse CC smooth muscle in vitro. MATERIALS AND METHODS Male C57BL/6 mice were used. CC tissues were mounted in organ baths. Measurement of cGMP in mice CC was evaluated. RESULTS The cumulative addition of heme concentrations promoted the relaxation of CC. HO inhibitor (1J, 100 μM) or sGC inhibitor (ODQ, 10 μM) blocked the relaxing effect of the heme group. Pre-incubation of CC with heme (100 μM) enhanced relaxation induced by acetylcholine, sodium nitroprusside, and nitrergic relaxation (electrical field stimulation), which was abolished by 1J or ODQ. The heme group increased the cGMP production in CC, which was abolished by 1J or ODQ. cGMP levels were significantly higher in CC treated with heme, and pre-incubation with compound 1J or ODQ abolished the effect of heme in raising cGMP levels. DISCUSSION AND CONCLUSION The HO-CO-sGC-cGMP pathway appears to play a crucial role in promoting CC relaxation. Our study provides novel insight into the role of group heme in CC relaxation and its potential contribution to priapism in SCD. Heme may serve as a pharmacological target for new therapies to prevent priapism.

Abstract
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 (n = 23, chi-squared = 59.943, PRR = 4.566), gabapentin (n = 20, chi-squared = 9.790, PRR = 2.060), lamotrigine (n = 16, chi-squared = 8.318, PRR = 2.120), levetiracetam (n = 16, chi-squared = 10.766, PRR = 2.329), topiramate (n = 14, chi-squared = 28.067, PRR = 3.972) and carbamazepine (n = 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.

Abstract
BACKGROUND Sleep-related painful erections are characterized by deep penile pain that occurs during erections in the rapid eye movement stage of sleep. CASE PRESENTATION This case presents a 43-year-old Chinese Han patient with sleep-related painful erections. Turgid painful erections (4-5 episodes of tumescence) during the sleep hours caused pain. Further, blood testing revealed an abnormal increase in white blood cells (123 × 109/L). The patient was diagnosed with chronic myeloid leukemia by bone marrow biopsy, BCR::ABL1 fusion gene testing, and Philadelphia chromosome. However, the sleep-related painful erections have dramatically decreased in frequency of erectile pain after chemotherapy for Chronic myeloid leukemia in our case. CONCLUSION We considered that the occurrence of sleep-related painful erections was related to chronic myeloid leukemia and the case might be secondary sleep-related painful erections.

Hydroxyurea does not reverse functional alterations of the nitric oxide-cGMP pathway associated with priapism phenotype in corpus cavernosum from sickle cell mouse. PLoS One 2023; 18:e0292706. [PMID: 37812620 PMCID: PMC10561851 DOI: 10.1371/journal.pone.0292706] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Accepted: 09/26/2023] [Indexed: 10/11/2023] Open
Abstract
Sickle cell disease (SCD) is a genetic disorder that has been associated with priapism. The role of hydroxyurea, a common SCD therapy, in influencing the nitric oxide (NO)-cGMP pathway and its effect on priapism is unclear. To investigate the effect of hydroxyurea treatment on smooth muscle relaxation of corpus cavernosum induced by stimulation of the NO-cGMP pathway in SCD transgenic mice and endothelial NO synthase gene-deficient (eNOS-/-) mice, which are used as model of priapism associated with the low bioavailability of endothelial NO. Four-month-old wild-type (WT, C57BL/6), SCD transgenic, and eNOS-/- male mice were treated with hydroxyurea (100 mg/Kg/day) or its vehicle (saline) daily for three weeks via intraperitoneal injections. Concentration-response curves for acetylcholine (ACh), sodium nitroprusside (SNP), and electrical field stimulation (EFS) were generated using strips of mice corpus cavernosum. The SCD mice demonstrated an amplified CC relaxation response triggered by ACh, EFS, and SNP. The corpus cavernosum relaxation responses to SNP and EFS were found to be heightened in the eNOS-/- group. However, the hydroxyurea treatment did not alter these escalated relaxation responses to ACh, EFS, and SNP in the corpus cavernosum of the SCD group, nor the relaxation responses to EFS and SNP in the eNOS-/- group. In conclusion, hydroxyurea is not effective in treating priapism associated with SCD. It is likely that excess plasma hemoglobin and reactive oxygen species, which are reported in SCD, are reacting with NO before it binds to GCs in the smooth muscle of the corpus cavernosum, thus preventing the restoration of baseline NO/cGMP levels. Furthermore, the downregulation of eNOS in the penis may impair the pharmacological action of hydroxyurea at the endothelial level in SCD mice. This study emphasize the urgency for exploring alternative therapeutic avenues for priapism in SCD that are not hindered by high plasma hemoglobin and ROS levels.

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.

[PMID: 37485311 PMCID: PMC10359136 DOI: 10.1155/2023/2263341] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Revised: 06/03/2023] [Accepted: 06/30/2023] [Indexed: 07/25/2023] Open
Abstract
Priapism is a prolonged involuntary erection that can have severe complications if left untreated. Ischaemic priapism is very rare in children and requires urgent intervention to prevent permanent erectile dysfunction and penile shortening. It can be caused by ischaemia in sickle cell anaemia, leukaemia, trauma, drugs, or idiopathy. Homocystinuria is a rare autosomal recessive disorder that can cause hyperhomocysteinemia and hypercoagulability. Very few reports suggested that priapism can be caused by hyperhomocysteinemia, and they were in adults. However, we present the first of such a case to the best of our knowledge of a prepubescent child who only had the MTHFR (C677T) mutation that causes homocystinuria and had ischaemic priapism. A nine-year-old Syrian Arab boy was presented with priapism that lasted for a few hours. Blood tests show normal blood count, film, and haemoglobin electrophoresis. However, prothrombin time, partial thromboplastin time, homocysteine level, and C-reactive protein were elevated. Other coagulation tests were within the normal range. Doppler ultrasonography found decreased cavernous blood flow, and warm 0.9% saline lavage of the cavernosa was indicated and successfully treated the priapism. Genetic testing for the homozygous MTHFR (C677T) mutation was later confirmed, and warfarin was indicated. In conclusion, homocystinuria is very rare in priapism, and this is the first case to report this phenomenon in a child. Ultrasonography in low-income countries is an essential tool that helps identify a wide variety of medical conditions such as priapism and can be successfully managed by aspiration with warm saline.

Abstract
The present study aimed to investigate the acute effects and the mechanism of ketamine on nicotine-induced relaxation of the corpus cavernosum (CC) in mice. This study measured the intra-cavernosal pressure (ICP) of male C57BL/6 mice and the CC muscle activities using an organ bath wire myograph. Various drugs were used to investigate the mechanism of ketamine on nicotine-induced relaxation. Direct ketamine injection into the major pelvic ganglion (MPG) inhibited MPG-induced increases in ICP. D-serine/L-glutamate-induced relaxation of the CC was inhibited by MK-801 (N-methyl-D-aspartate (NMDA) receptor inhibitor), and nicotine-induced relaxation was enhanced by D-serine/L-glutamate. NMDA had no effect on CC relaxation. Nicotine-induced relaxation of the CC was suppressed by mecamylamine (a non-selective nicotinic acetylcholine receptor antagonist), lidocaine, guanethidine (an adrenergic neuronal blocker), Nw-nitro-L-arginine (a non-selective nitric oxide synthase inhibitor), MK-801, and ketamine. This relaxation was almost completely inhibited in CC strips pretreated with 6-hydroxydopamine (a neurotoxic synthetic organic compound). Ketamine inhibited cavernosal nerve neurotransmission via direct action on the ganglion and impaired nicotine-induced CC relaxation. The relaxation of the CC was dependent on the interaction of the sympathetic and parasympathetic nerves, which may be mediated by the NMDA receptor.

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
BACKGROUND High flow priapism (HFP) is a rare type of priapism. Perineal trauma is the most common cause of HFP. Trauma-induced penile artery injury may lead to an arterial-cavernosal fistula, whereas persistent irregular arterial blood flow entering the corpora cavernosum can cause a persistent penile erection. The routine treatment of HFP focuses on addressing the abnormal penile erectile status and avoiding post-treatment erectile dysfunction. Interventional embolization is an important therapeutic modality for HFP, and bilateral embolization therapy is currently the most commonly used technique for patients with bilateral cavernous artery fistulas; however, unilateral embolization therapy has yet to be reported.
CASE SUMMARY Herein, we report of the case of a 26-year-old Chinese male who presented with a persistent abnormal erection for 12 h after perineal impact injury. Medical history, cavernous arterial blood gas analysis and radiological examinations led to a diagnosis of HFP caused by bilateral cavernous artery fistulas. We performed routine conservative treatment (compression therapy and ice application) for the patient after admission; however, 10 d later, his symptoms had not been relieved. After completion of the preoperative workup, right (severe side) selective perineal artery embolization was performed; the left cavernous artery fistula was left untreated. After postoperative continuation of conservative treatment for 72 h, the patient experienced complete penile thinning. The patient had no symptoms of erectile dysfunction over a follow-up period of 12 mo.
CONCLUSION Compared with bilateral cavernous artery fistula embolization, we believe that unilateral cavernous artery fistula embolization can achieve positive clinical efficacy and reduce the risk of postoperative erectile dysfunction secondary to penile ischemia.

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.

Abstract
Purpose of Review
There is a paucity of peer-reviewed evidence to guide medical management of stuttering priapism. The purpose of this review is to summarize the current understanding regarding the pathophysiology of priapism and management options for stuttering priapism.
Recent Findings
Conducting large-scale, randomized, placebo-controlled trials that elucidate the optimal treatment of stuttering priapism is challenging. Therefore, recent treatment guidelines are based upon small case series, retrospective studies, and expert opinions. Nonetheless, multiple compounds from various drug classes have shown promise in treating stuttering priapism, and a few pharmacotherapies such as Crizanlizumab are currently under active investigation.
Summary
Stuttering priapism is an under-investigated disorder with a complex pathophysiology. Currently, there is no wildly adopted universal therapeutic strategy. Further research is warranted to identify the appropriate treatment of stuttering priapism and to determine the long-term side effects of current pharmacotherapies.

Abstract
Patients with sickle cell disease (SCD) display priapism. Clinical studies have shown a strong positive correlation between priapism and high levels of intravascular hemolysis in men with SCD. However, there are no experimental studies that show that intravascular hemolysis promotes alterations in erectile function. Therefore, we aimed to evaluate the corpus cavernosum smooth muscle relaxant function in a murine model that displays intravascular hemolysis induced by phenylhydrazine (PHZ), as well as the role of intravascular hemolysis in increasing the stress oxidative in the penis. Corpus cavernosum strips were dissected free and placed in organ baths. Acetylcholine and electrical field stimulation (EFS)-induced corpus cavernosum relaxations in vitro were obtained. Increased corpus cavernosum relaxant responses to acetylcholine and EFS were observed in the PHZ group. Protein expression of heme oxygenase-1 increased in the corpus cavernosum of the PHZ group, but PDE5 protein expression was not modified. Preincubation with the heme oxygenase inhibitor 1 J completely reversed the increased relaxant responses to acetylcholine and EFS in PHZ mice. Protein expression of NADPH oxidase subunit gp91phox, 3-nitrotyrosine, and 4-hydroxynonenal increased in the corpus cavernosum of the PHZ group, suggesting a state of oxidative stress. Basal cGMP production was lower in the PHZ group. Our results show that intravascular hemolysis promotes increased corpus cavernosum smooth muscle relaxation associated with increased HO-1 expression, as well as increased oxidative stress associated with upregulation of gp91phox expression. Moreover, our study supports clinical studies that point to a strong positive correlation between priapism and high levels of intravascular hemolysis in men with SCD.

Abstract
Simple Summary A 5-year-old recently castrated male Doberman dog presented for prolonged erection of one week’s duration with associated pain and dysuria. This was the fourth episode within a year. Each episode was associated with an unusual event, which was stressful for the dog. Castration performed two months prior to the final episode did not prevent recurrence. Due to tissue necrosis, penile amputation and urethrostomy had to be performed. To our knowledge, this case is the first report of a stuttering priapism in a dog. Stuttering priapism, also called recurrent or intermittent priapism, is a particular type of ischemic priapism described in humans that is characterized by repeated episodes of prolonged erections. Abstract A 5-year-old recently castrated male Doberman dog presented for prolonged erection of one week’s duration with associated pain and dysuria. This was the fourth episode within a year. Each episode was associated with an unusual event, which was stressful for the dog. Castration performed two months prior to the final episode did not prevent recurrence. Due to tissue necrosis, penile amputation and urethrostomy had to be performed. The dog recovered fully. Prolonged erection that persists beyond or that is unrelated to sexual stimulation is called “priapism”. This term refers to the Greek god Priapus, a god of fertility, memorialized in sculptures for his giant phallus. In humans, depending on the mechanism involved, priapism is classified as nonischemic or ischemic. Because prognosis and treatment are different, priapism must be determined to be nonischemic or ischemic. Nonischemic priapism is a rare condition observed when an increase in penile arterial blood flow overwhelms the capacity of venous drainage; it is often associated with penile trauma, and does not require medical intervention. Ischemic priapism is associated with decreased venous return. In humans, ischemic priapism accounts for 95% of cases, the majority of which are idiopathic. Ischemic priapism is a urological emergency; simple conservative measures such as aspiration of blood from the corpora cavernosa and intracavernosal injection of an adrenergic agent are often successful. Stuttering priapism, also called recurrent or intermittent priapism, is a particular form of ischemic priapism reported in humans that is characterized by repetitive episodes of prolonged erections. Management consists of treating each new episode as an episode of acute ischemic priapism, and preventing recurrence with oral medications such as dutasteride and/or baclofen, gabapentin, or tadalafil. To the authors’ knowledge, this case is the first report of stuttering priapism in a dog.

Haptoglobin treatment contributes to regulating nitric oxide signal and reduces oxidative stress in the penis: A preventive treatment for priapism in sickle cell disease. Front Physiol 2022; 13:961534. [PMID: 36176769 PMCID: PMC9514379 DOI: 10.3389/fphys.2022.961534] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Accepted: 08/24/2022] [Indexed: 11/25/2022] Open
Abstract
Background: In sickle cell disease (SCD), reduced bioavailability of endothelial NO and cGMP results in reduced expression of phosphodiesterase type 5 (PDE5), thus impairing the penile erection control mechanism and resulting in prolonged penile erection (priapism). In SCD, reduced NO bioavailability is associated with excess plasma hemoglobin due to intravascular hemolysis and increased oxidative stress. Haptoglobin is the plasma protein responsible for reducing plasma hemoglobin levels, but in SCD, haptoglobin levels are reduced, which favors the accumulation of hemoglobin in plasma. Therefore, we aimed to evaluate the effects of haptoglobin treatment on functional and molecular alterations of erectile function, focusing on the contractile and relaxant mechanisms of corpus cavernosum (CC), as well as oxidative stress. Methods: SCD mice were treated with haptoglobin (400 mg/kg, subcutaneous) or vehicle of Monday, Wednesday and Friday for a period of 1 month. Corpus cavernosum strips were dissected free and placed in organ baths. Cumulative concentration-response curves to the acetylcholine, sodium nitroprusside, phenylephrine and KCL, as well as to electrical field stimulation (EFS), were obtained in CC. Protein expressions of eNOS, phosphorylation of eNOS at Ser-1177, nNOS, PDE5, ROCK1, ROCK2, gp91phox, 3-nitrotyrosine, and 4-HNE were measured by western blot in CC. Results: Increased CC relaxant responses to acetylcholine, sodium nitroprusside and electrical-field stimulation were reduced by haptoglobin in SCD mice. Reduced CC contractile responses to phenylephrine and KCl were increased by haptoglobin in SCD mice. Haptoglobin prevented downregulated eNOS, p-eNOS (Ser-1177), PDE5, and ROCK2 protein expressions and reduced protein expressions of reactive oxygen species markers, NADPH oxidase subunit gp91phox, 3-nitrotyrosine and 4-HNE in penises from SCD mice. Haptoglobin treatment did not affect ROCK1 and nNOS protein expressions in penises from SCD mice. Basal cGMP production was lower in the SCD group, which was normalized by haptoglobin treatment. Conclusion: Treatment with haptoglobin improved erectile function due to up-regulation of eNOS-PDE5 expression and down-regulation of the gp91phox subunit of NADPH oxidase and oxidative/nitrosative stress in the penises of SCD mice. Treatment with haptoglobin also increased contractile activity due to up-regulation of ROCK2. Therefore, haptoglobin treatment may be an additional strategy to prevent priapism in SCD.

Abstract
OBJECTIVES To determine the safety and efficacy of hourly, high dose phenylephrine (>1000 μg) for acute ischemic priapism (AIP) through monitoring adverse hemodynamic events amongst risk profiles. METHODS An IRB-approved retrospective review of patients with AIP from 2010-2020. Patients were stratified to a low or high dose phenylephrine group based on cumulative, hourly dose of ≤1000 μg and > 1000 μg respectively and examined for successful resolution of their AIP. The safety profile of phenylephrine for patients at risk for adverse hemodynamic events was examined. RESULTS A total of 123 patients were identified with a median age of 40 (range: 7-76) years with median time from AIP onset to presentation of 11 (2-168) hours. 97 men received phenylephrine (78.9%) and detumescence was achieved nonoperatively in 62 of these men (63.9%) with a mean priapism duration of 8.7 hours. Those resolving with phenylephrine administration had a mean duration of 8.8 ± 5.6 versus 57.3 ± 37.1 hours without resolution p < 0.001. Among low and high dose phenylephrine groups (500 and 2000 μg respectively), the median duration of AIP was 10 and 12 hours respectively without a difference in AIP resolution (p > 0.05). Twenty-one patients (17.1%) were deemed at risk for phenylephrine complication of which 4 (4.1%) had phenylephrine discontinued due to hemodynamic changes. CONCLUSIONS Nonoperative resolution of AIP with phenylephrine does not appear to be dose-dependent and hemodynamic changes secondary to phenylephrine administration may be underreported. Future work should utilize standardized risk assessment and periprocedural monitoring for hemodynamic change.

Abstract
Priapism is a well‐known urologic complication of sickle cell anemia. This study describes the results of a protocol for the treatment of acute priapism by intracavernous injection of epinephrine due to unavailability of etilefrine. A descriptive cross‐sectional study of 18 cases of acute priapism in sickle cell patients treated in the pediatric department of the Sylvanus Olympio CHU from January 1 to December 31, 2020. The average age was 21.7 ± 7.7 years, the youngest patient was 8 and the oldest was 32 years old. Students represented 61.1% of the patients. The hemoglobin profiles were homozygous SS (n = 14) and double heterozygous SC (n = 4). Most of the crisis (83.3%) occurred at night. Most of the patients (66.7%) came to the hospital before the sixth hour of crisis, one patient came by the 48th hour. Walking was the most self‐relief method tried by patients (67%). It was followed by a cold penile bath, attempted urination, body bath, and lastly lukewarm bath. Fourteen patients had a history of chronic intermittent priapism. The average pain intensity was 9.5 ± 0.9 with restlessness (33.3%) and crying (33.3%). Fifteen patients were treated upon admission with an intracavernosal injection of epinephrine, and three patients were first drained. Thirteen patients achieved remission immediately, while five patients required a second injection and only one had to be drained before remission. Tolerance was good. One patient had a borderline systolic blood pressure. One erectile weakness case was noticed and no cases of sexual impotence. Epinephrine by intracavernosal injection is an efficient treatment for acute priapism in sickle cell patients. Epinephrine, which has a good tolerance in pediatric and young adult patients, should be used in lieu of etilefrine due to its unavailability in areas where it is unavailable.

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.

Abstract
OBJECTIVE This study aimed to evaluate the predictive value of platelet volume indices (PVIs), such as mean platelet volume (MPV), platelet distribution width (PDW), and plateletcrit (PCT), as prognostic parameters of detumescence in acute ischemic priapism (IP) patients with sickle cell anemia (SCA) in steady-state who received intracavernosal injections of phenylephrine with aspiration and saline irrigation. METHODS Fifty-six SCA patients with acute IP and 54 healthy male control subjects were included in the research. Priapism was diagnosed by penile Doppler ultrasound and corporal blood gas tests before intervention. Measurements of PVIs (MPV, PDW, and PCT) and TLC were ordered for all participants. Additionally, the duration of priapism was recorded. The area under the curves was calculated by receiver operating characteristic (ROC) regression analysis. RESULTS The detumescence rate was 71.4% after the intervention. Compared to the control group, priapic SCA patients showed significantly higher PLT (p = 0.011), MPV (p = 0.002), PDW (p = 0.032), PCT values (p = 0.022), and TLC (p = 0.027). Higher MPV, PDW, and PCT values were observed in unsuccessful detumescence patients compared to the resolution group (p < 0.05). Statistically significant cutoff values for persistent priapism were measured by ROC as PLT: ⩾ 254x103/μL; MPV: ⩾ 13.2 fL; PDW: ⩾ 15.6 fL; PCT: ⩾ 24%; and TLC ≥ 8.5x103/L. Priapism duration of ≤ 17.9 hours was significantly related to detumescence rate (p = 0.000). Multivariable logistic regression analysis showed that priapism duration and higher MPV are prognostic parameters for detumescence in SCA. CONCLUSIONS The higher MPV and duration of priapism can be used as parameters for evaluating detumescence outcomes in steady-state SCA with acute IP.

Abstract
Priapism is a persistent penile erection lasting longer than 4 hours, that needs emergency management. This disorder can induce irreversible erectile dysfunction. There are three subtypes of priapism: ischemic, non-ischemic, and stuttering priapism. If the patient has ischemic priapism (IP) of less than 24-hours (h) duration, the initial management should be a corporal blood aspiration followed by instillation of phenylephrine into the corpus cavernosum. If sympathomimetic fails or the patient has IP from 24 to 48h, surgical shunts should be performed. It is recommended that distal shunts should be attempted first. If distal shunt failed, proximal, venous shunt, or T-shunt with tunneling could be performed. If the patient had IP for 48 to 72h, proximal and venous shunt or T-shunt with tunneling is indicated, if those therapies failed, a penile prosthesis should be inserted. Non-ischemic priapism (NIP) is not a medical emergency and many patients will recover spontaneously. If the NIP does not resolve spontaneously within six months or the patient requests therapy, selective arterial embolization is indicated. The goal of the management of a patient with stuttering priapism (SP) is the prevention of future episodes. Phosphodiesterase type 5 (PDE5) inhibitor therapy is considered an effective tool to prevent stuttering episodes but it is not validated yet. The management of priapism should follow the guidelines as the future erectile function is dependent on its quick resolution. This review briefly discusses the types, pathophysiology, and diagnosis of priapism. It will discuss an updated approach to treat each type of priapism.

Abstract
Background Children and adult with sickle cell disease (SCD) display priapism associated with low nitric oxide (NO) bioavailability and oxidative stress in penis. Aim This study aimed to evaluate the effects of hybrid compound RVT-FxMe, derived from resveratrol bearing a NO-donor subunit, on two murine model that display priapism phenotype, SCD transgenic mice and endothelial NO synthase gene-deficient (eNOS-/-) mice. Methods Wild-type, SCD, and eNOS-/- mice were treated with RVT-FxMe (25 mg/kg/d, 2 weeks). Outcomes Hematological parameters, concentration-response curves to acetylcholine (ACh) and sodium nitroprusside (SNP), as well as to electrical field stimulation (EFS), were obtained in mice corpus cavernosum strips. Results Corpus cavernosum relaxations to SNP and EFS were increased in eNOS-/- group, which were normalized by RVT-FxMe treatment. SCD mice exhibited an excessive CC relaxant response induced by ACh, EFS and SNP RVT-FxMe treatment did not change the increased relaxant responses to ACh, EFS and SNP in corpus cavernosum from SCD group. Clinical translation Excess of plasma hemoglobin in SCD may interfere in pharmacological activity of NO donors compounds. Strength/Limitations While mechanistic data with promising potential is showed, the current study is not without limitations. RVT-FxMe effects in the mid- and long-term warrant complementary studies. Conclusion Treatment with RVT-FxMe reversed the enhanced NO-cGMP-mediated CC relaxations in eNOS-/- mice, but not in SCD mice; it is likely that excess of plasma hemoglobin in SCD mice act to inactivate NO before it reaches soluble guanylyl cyclase, avoiding restoration of NO bioavailability in penis.

Abstract
OBJECTIVES The objective of this study was to evaluate the sexuality of SS sickle cell patients with a history of priapism. METHODS This was a case-control study of adult SS sickle cell patients. The occurrence of priapism as well as the nature of the priapism had been investigated. The patients were subdivided into three groups: Group 1 (no priapism), Group 2 (intermittent priapism) and Group 3 (acute priapism). The patients' sexuality was studied using the IIEF-15 questionnaire. RESULTS We interviewed 191 SS sickle cell patients. The mean age was 27.1±7.1 years. Priapism was observed in 43.5 %. Only 77 patients were eligible for the IIEF15 questionnaire. Groups 1 and 2 performed significantly better than group 3 on erectile function (EF) and orgasmic function (OF) scores. There was no significant difference in the EF and OF scores between groups 1 and 2. No significant difference was observed between the three groups for the scores of sexual desire (SD), intercourse satisfaction (IS), and overall satisfaction (OS). The impairment of erectile function in group 2 was related to the age of the first episode of priapism and the last episode. The impairment of erectile function in group 3 was related to the duration of evolution (P<0.05). CONCLUSION This study shows that priapism is responsible for impaired erectile function in SS adult sickle cell patients. A program to prevent intermittent episodes of priapism should be put in place.

Lu Y, Zhang J, Su H, Xiao Y, Guo B, Li H. Improvement of associated symptoms using combined therapy in 44 patients with sleep-related painful erection during 1-year follow up. Andrologia 2022; 54:e14472. [PMID: 35593076 DOI: 10.1111/and.14472] [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: 12/12/2021] [Revised: 04/06/2022] [Accepted: 05/03/2022] [Indexed: 11/27/2022] Open
Abstract
The current study was aimed at analysing the clinical features and efficacy of combined treatments in patients with sleep-related painful erection (SRPE). Patients who presented with SRPE were continuously enrolled from the outpatient clinic of Peking Union Medical College Hospital from 2015 to 2021. Demographic data, medical history, diagnostics, treatment options and their effectiveness on SRPE in the short and long therapeutic term were recorded. Individually designed combined therapy aimed at controlling SRPE-related symptoms and comorbidities (general health, pain, psychological and sleeping disorders, late-onset hypogonadism, and lower urinary tract symptoms) was used, and the effectiveness was evaluated. In total, 44 patients with an average age of 44.66 ± 7.96 years were enrolled. The median length of the delay in diagnosis was 1.5 years (range, 1 month to 27 years). Combined treatment aimed at controlling symptoms was used, the mean GAD-7, PHQ-9, PSQI and VAS scores were significantly decreased to 4.25 ± 3.44, 4.55 ± 2.86, 7.65 ± 3.06, and 2.90 ± 1.89 after treatment for 3 months. Moreover, the VAS ratings were significantly decreased at 1 year of follow-up (p < 0.001). SRPE mainly occurred in middle aged males, 79.55% (35/44) patients were more than 40 years old. The prevalence of anxiety, depression, poor sleep and nocturia is high in patients with SRPE. Combined treatments aimed at controlling these symptoms can be more effective.

Abstract
PURPOSE OF REVIEW Priapism is a rare condition that has different presentations, etiologies, pathophysiology, and treatment algorithms. It can be associated with significant patient distress and sexual dysfunction. We aim to examine the most up-to-date literature and guidelines in the management of this condition. RECENT FINDINGS Priapism is a challenging condition to manage for urologists, since the etiology is often multi-factorial and the suggested treatment algorithms are based on small studies and expert anecdotal experience, perhaps due to the rarity of the disorder. Ischemic priapism of less than 24 h can be managed non-surgically in most cases with excellent results. Ischemic priapism of more than 36 h is frequently associated with permanent erectile dysfunction. Management of prolonged priapism with penile shunting still may result in poor erectile function, so penile prosthesis can be discussed in these scenarios.

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 is an urgent urological condition with varied aetiology that may be classified as low flow (ischaemic) or high flow (non-ischaemic). Diagnosis requires detailed clinical history and examination combined with appropriate investigations such as cavernosal blood gas sampling and penile Doppler ultrasound. In the case of high-flow priapism CT angiography can identify sources of abnormal arterial blood flow and cases may be managed conservatively, with surgery or through arterial embolisation. We detail a case of a young man presented 2 weeks after perineal trauma with high-flow priapism with an equivocal penile Doppler ultrasound. Cavernosal blood gas sampling was consistent with arterial blood and CT angiography was performed showing an arteriovenous fistula. The patient was then successfully managed with arterial embolisation resulting in detumescence and preserving sexual function.

A population-based analysis of predictors of penile surgical intervention among inpatients with acute priapism. Int J Impot Res 2022; 35:107-113.

Abstract
While consensus exists regarding risk factors for priapism, predictors of operative intervention are less well established. We assessed patient and hospital-level predictors associated with penile surgical intervention (PSI) for patients admitted with acute priapism, as well as length of stay (LOS) and total hospital charges using the National Inpatient Sample (2010-2015). Inpatients with acute priapism were stratified by PSI, defined as penile shunts, incisions, and placement of penile prostheses, exclusive of irrigation procedures. Survey-weighted logistic regression models were utilized to assess predictors of PSI. Negative binomial regression and generalized linear models with logarithmic transformation were used to compare PSI to LOS and total hospital charges, respectively. Among 14,529 weighted hospitalizations, 4,953 underwent PSI. Non-Medicare insurances, substance abuse, and ≥3 Elixhauser comorbidities had increased odds of PSI. Conversely, Black patients, sickle cell disease, alcohol abuse, neurologic diseases, malignancies, and teaching hospitals had lower odds. PSI coincided with shorter median LOS (adjusted IRR: 0.62; p < 0.001) and lower ratio of the mean hospital charges (adjusted Ratio: 0.49; p < 0.001). Additional subgroup analysis revealed penile incisions and shunts primarily associated with reduced LOS (adjusted IRR: 0.66; p < 0.001) and total hospital charges (adjusted Ratio: 0.49; p < 0.001). Further work is required to understand predictors of poor outcomes in these populations.

Abstract
We report the case of a 14-year-old man who arrived at the emergency department affected by a high-flow priapism due to a traumatic left arterial-sinusoidal fistula. After clinical examination, a colour Doppler ultrasound of the penis was performed which showed a left arterial-sinusoidal fistula measuring 7×16×30mm, with high-speed and turbulent flow. The fistula was successfully treated by three highly selective endovascular embolizations and at the 20days follow-up, clinical examination resulted normal.

Abstract
Objective Through critical analysis and comprehensive review of the limited literature, this paper can help clinicians better identify the pathophysiology of sleep-related painful erections (SRPE) and provide direction for future treatment research. Background Patients with SRPE will be awakened by painful erections during sleep, which affects their sleep process and general health. At present, literatures of experimental and clinical research on SRPE disease are limited, as well as long-term reports on its pathogenesis and clinical management. Methods We use the PubMed database to obtain sleep-related peer erection literature. The search terms used include sleep, painful, penis and erection. After rigorous screening, the search returned 21 references published between 1987 and 2021. Conclusions The main cause of SRPE is obstructive sleep apnea (OSA) syndrome, psychological and spiritual factors, androgen elevation, neuroendocrine regulation and threshold of pain in the REM phase. The combination of multiple medications is the most effective approach to treat sleep-pain-related erections. The combination of CPAP, REM inhibitors and Baclofen has significant effect on SRPE caused by OSA syndrome. This article provides effective support and strategies for doctors to manage SRPE patients through a comprehensive analysis of the pathogenesis mechanism and clinical treatment strategies of SRPE.

Abstract
A 14-year-old neutered male British shorthair cat presented with a 21-day history of persistent erection and dysuria, along with overgrooming of the perineal region. Mild palpation induced pain and rigid corpora cavernosa with flaccid glans were observed during physical examination. Ultrasonography of the penis did not detect significant blood flow in the penile cavernosal artery. The drawing of aspirate blood from cavernosal bodies for gas analysis was impossible because of the anatomically small penis size of cats. Conservative management, including topical steroid ointment, lidocaine gel, gabapentin, and diazepam, was prescribed for supportive management. The clinical signs resolved, and ultrasonographic examination of the penis revealed no abnormalities. The cat remains clinically well without recurrence during the 6 months after treatment. To our knowledge, this is the first report of non-ischemic priapism in a cat.

Abstract
Priapism is defined as an erection that lasts longer than four hours, is unrelated to sexual interest or stimulation, and is unrelieved by orgasm. The ischemic subtype is a urologic emergency and is often caused by medication side effects, most notably selective serotonin reuptake inhibitors and trazodone. We present the case of ischemic priapism thought to be caused by the recent initiation of gabapentin.
