Priapismo y leucemia mieloide crónica en adolescente. Debut poco frecuente. Reporte de caso / Priapism and chronic myeloid leukemia in an adolescent. Rare debut presentation. A case report

El priapismo es una erección dolorosa y persistente acompañada o no de estímulo sexual. Una causa poco frecuente de esta anormalidad es la leucemia mieloide crónica. Se han reportado pocos casos de priapismo como manifestación inicial de una leucemia de este tipo en pacientes adolescentes. A continuación, se informa el caso de un paciente de 16 años de edad que presentó priapismo como manifestación inicial de una leucemia mieloide crónica. Durante su evolución, no se realizó aspiración de los cuerpos cavernosos. Se inició tratamiento hematológico específico y, ante la persistencia del priapismo, fue necesario realizar un shunt de cuerpos cavernosos en dos ocasiones, tratamiento a pesar del cual existen altas probabilidades de secuelas.

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.

Profil épidémiologique des urgences péniennes au CHU de Libreville / Epidemiological profile of penile emergencies at the University Hospital of Libreville

Introduction : Les urgences péniennes sont multiples et variées. Elles peuvent mettre en jeu le pronostic fonctionnel sexuel du patient. L'objectif de notre étude était de rapporter les aspects cliniques et thérapeutiques des urgences péniennes au CHU de Libreville. Matériel et Méthodes : Nous avons réalisé une étude rétrospective de janvier 2016 à décembre 2020 au service d'urologie du CHU de Libreville. Les variables comprenaient les données sociodémographiques, cliniques et thérapeutiques des patients pris en charge pour une urgence pénienne. Résultats : Durant cette période, 63 patients ont été pris en charge pour urgences péniennes. L'âge moyen était de 27±17,3 ans avec des extrêmes de 1 et 90 ans. Les urgences péniennes les plus fréquentes étaient le priapisme (55,5%) et la fracture de verge (15,9%). Le délai moyen de consultation en urologie était de 121 343,3 heures pour une médiane de 10 heures tandis que celui de prise en charge était de 34,3±74,6 pour une médiane de 2 heures. Les principaux gestes effectués étaient la ponction des corps caverneux (n=29, 46%) suivie de l'albuginorraphie (n=9, 14,3%) et du shunt caverno spongieux (n=9, 14,3%). Conclusion : Les urgences péniennes sont relativement fréquentes. Elles sont dominées par le priapisme et la fracture de verge dans notre contexte. Le pronostic fonctionnel sexuel est bon mais le délai de prise en charge demeure encore long.

Introduction: Penile emergencies are multiple and varied. They can jeopardize the patient's functional sexual prognosis. The objective of our study was to report the clinical and therapeutic aspects of penile emergencies at the University Hospital of Libreville. Material and Methods: We conducted a retrospective study from January 2016 to December 2020 at the Urology Department of the CHU of Libreville. Variables included sociodemographic, clinical and therapeutic data of patients managed for a penile emergency. Results: During this period, 63 patients were managed for penile emergencies. The mean age was 27±17.3 years with extremes of 1 and 90 years. The most frequent penile emergencies were priapism (55.5%) and penile fracture (15.9%). The mean time to consultation in urology was 121,343.3 hours with a median of 10 hours, while the mean time to management was 34.3±74.6 with a median of 2 hours. The main procedures performed were corpora cavernosa puncture (n=29, 46%) followed by albuginorraphy (n=9, 14.3%) and cavernospongiosus shunt (n=9, 14.3%). Conclusion: Penile emergencies are relatively frequent. They are dominated by priapism and penile fracture in our context. The sexual functional prognosis is good but the delay of management remains long.

Aspectos prácticos en la patología venosa del pene / Practical Aspects in Venous Pathology of the Penis

El objetivo del presente artículo es mostrar una serie de alteraciones peneanas que, aunque frecuentes en la consulta de medicina sexual, son minimizadas, la mayoría de las veces por desconocimiento de los terapeutas, aunque para los pacientes que las padecen sean genuinas tragedias personales. Hemos revisado la literatura disponible sobre un grupo de seis patologías venosas especificas del pene que configuran el grupo más representativo. Se incluyen las frecuentes e indolentes venas superficiales tortuosas, los cirsoceles o flebectasias, las fugas venosas dorsales, que suelen ser una patología congénita, las deformantes malformaciones venosas del glande, la desconcertante y enigmática enfermedad de Mondor, y las fístulas arteriovenosas, con su riesgo de priapismo de alto flujo implícito. Todas se consideran alteraciones patológicas que requieren intervenciones menores en su tratamiento, excepto ciertos casos de fugas venosas y de fístulas, cuyo manejo es invasivo, y que, en conjunto, buscan una mejor comprensión de los hallazgos cotidianos en este órgano.

The objective of the present article is to describe a series of penile alterations that, although frequent in the sexual medicine consultation, are minimized, most of the time due to ignorance of the therapists, but, for the patients who suffer them, they are real personal tragedies. We have reviewed the literature available on a group of six specific venous pathologies of the penis that make up the most representative group. They include the frequent and indolent tortuous superficial veins, the cirsoceles or phlebectasias, the dorsal venous leaks, which are usually a congenital pathology, the deforming venous malformations of the glans, the enigmatic Mondor disease, and the arteriovenous fistulas, with their implicit risk of high-flow priapism. All are considered pathological alterations that require minor interventions in their treatment, except for certain cases of venous leaks and fistulas, whose management is invasive, and which together seek a better understanding of the common findings in this organ.

Priapismo: abordaje clínico y manejo de urgencia / Priapism: clinical approach and emergency management

Priapism is a persistent erection, often painful, lasting more than 4 hours and unrelated to sexual stimulation. Based on clinical and pathophysiological features, priapism can be classified as ischemic, nonischemic and stuttering. Ischemic priapism is the most frequent form and represents a urological emergency. Although it is described as a low frequency entity, its timely diagnosis and immediate intervention are essential in the reestablishment of cavernous blood flow and in the prevention of necrosis and permanent erectile dysfunction. Intracavernous blood aspiration and injection of a-adrenergic agents correspond to the first-line options for the management of cases of ischemic priapism. Surgical shunts continue to be the most widely used surgical option for the management of prolonged ischemic priapism refractory to non-invasive management, with emerging evidence supporting the early implantation of a penile prosthesis. The objective of this review article is to describe the keys to the clinical approach and acute management of priapism in the emergency department. (AU)

Prevalence of priapism in individuals with sickle cell disease and implications on male sexual function / Prevalência de priapismo em indivíduos com doença falciforme e suas implicações na função sexual masculina

ABSTRACT Objective To evaluate epidemiological aspects of priapism in patients with sickle cell disease, and these aspects impact on adult sexual function. Methods This was a cross-sectional study including individuals with sickle cell disease who were evaluated at a reference center for sickle cell. Participants completed a structured questionnaire about their sociodemographic characteristics and priapism events. Sexual function was assessed using validated two instruments, the Erection Hardness Score and one about the sex life satisfaction. Results Sixty-four individuals with median aged of 12 (7 to 28) years were interviewed. The prevalence of priapism was 35.9% (23/64). The earliest priapism episode occurred at 2 years of age and the latest at 42 years. The statistical projection was that 71.1% of individuals of the study would have at least one episode of priapism throughout life. Patients with episodes of priapism (10/23) had significantly worse erectile function Erection Hardness Score of 2 [1-3]; p=0.01 and were less satisfied with sexual life 3 [3-5]; p=0.02. Conclusion Priapism is usually present in childhood, and severe episodes are associated with cavernous damage, impairment in the quality of the erection, and lower sexual satisfaction.

RESUMO Objetivo Avaliar aspectos epidemiológicos do priapismo em pacientes com doença falciforme e o impacto desses aspectos na função sexual de adultos. Métodos Trata-se de estudo transversal, que incluiu indivíduos com doença falciforme acompanhados em um centro de referência. Os participantes responderam a um questionário estruturado acerca das características sociodemográficas e eventos de priapismo. A função sexual foi avaliada por meio de dois instrumentos validados, a Escala de Rigidez de Ereção e um sobre satisfação com a vida sexual. Resultados Foram entrevistados 64 indivíduos com média de idade de 12 (7-28) anos. A prevalência de priapismo foi de 35,9% (23/64). O episódio mais precoce ocorreu aos 2 anos de idade e o mais tardio, aos 42 anos. A projeção estatística foi de que 71,1% desses sujeitos teriam pelo menos um episódio de priapismo ao longo da vida. Pacientes adultos com episódios de priapismo (10/23) apresentaram função erétil significativamente pior Escala de Rigidez de Ereção de 2 [1-3]; p=0,01 e estavam menos satisfeitos com a vida sexual 3 [3-5]; p=0,02. Conclusão O priapismo manifesta-se desde a infância, e episódios graves estão associados a dano cavernoso, prejuízo na qualidade da ereção e menor satisfação sexual.

Reconstrucción de pene luego de necrosis de glande por priapismo / Penile Reconstruction after Glans Necrosis by Priapism

Introducción El priapismo se define como una erección parcial o completa que dura más de 4 horas en ausencia de estímulo sexual. Se clasifica en isquémico, no isquémico e intermitente. El primero corresponde a la mayoría de casos y puede producirse por un estímulo sexual o por medicamentos. El manejo inicial consiste en la aspiración de los cuerpos cavernosos y la inyección de simpaticomiméticos. Cuando esas medidas fallan, el manejo quirúrgico está indicado. Entre las complicaciones más frecuentes está la disfunción eréctil, sin embargo, en la literatura, hay muy pocos reportes de necrosis de pene. Descripción del Caso Clínico Paciente de 60 años de edad que presentó priapismo isquémico luego de la inyección intracavernosa de prostaglandina E. Viene a consulta y le realizan lavado de cuerpos cavernosos con inyección de simpaticomiméticos que no fue exitoso; por lo que le realizan fístula espongio-cavernosa distal (Al-Ghorab) y rafia de uretra por lesión advertida. Consulta nuevamente por persistencia de edema, áreas necróticas y sangrado en glande. Se decidió iniciar manejo médico. Presentó evolución estacionaria y aumento en necrosis por lo que se derivó con cistostomía y se realizó desbridamiento de tejido necrótico inicialmente. Posteriormente se realizó Reconstrucción peneana + Uretroplastia peneana + Lavado desbridamiento de tejidos + Cistoscopia con buena evolución clínica. Conclusiones Existen diferentes factores de riesgo para presentar priapismo de origen isquémico como es la inyección de medicamentos intracavernosos. La principal complicación que se presenta es la disfunción eréctil. Sin embargo, hay pocos casos descritos de necrosis de glande. En el caso de nuestro paciente se plantean diferentes hipótesis como factores contribuyentes a la necrosis como son el uso de simpaticomiméticos y/o la desvascularización del glande posterior a la cirugía. Al enfocar ese tipo de paciente, es indispensable realizar un adecuado manejo inicial para prevenir ese tipo de complicación que, aunque es poco frecuente, puede resultar catastrófica.

Introduction Priapism is defined as a prolonged and persistent penile erection that is unrelated to sexual stimulation and lasts longer than 4 hours in duration. It is classified as ischemic (low flow), non-ischemic (high flow), and stuttering (recurrent). Ischemic priapism is the most frequent. Initial treatment consists of corpora cavernosa aspiration. When it fails, surgical treatment is indicated. Erectile dysfunction is a frequent complication, however glans necrosis has been reported too. Case Report A 60 year-old patient with ischemic priapism after prostaglandin E intracavernous injection consulted. Initial treatment was corpora cavernosa aspiration without detumecense and then a distal espongio-cavernous fistula was done. Some days later, he presented edema, bloods and necrotic areas in his glands. Conservative medical treatment was done without success and a surgical treatment was considered. Reconstructive procedure was done with good evolution. Conclusions Ischemic priapism could be presented after intracavernous injection with low frequency. However, an appropriate treatment has to be done to prevent complications as penile necrosis. In this patient, there are some risk factors that could be contribute to glans necrosis as simpatico-mimetics used, lost of vascularization with surgery. When focusing on this type of patient, it is essential to carry out an adequate initial management to prevent this type of complication that, although rare, can result catastrophic

Self-care of men with priapism and sickle cell disease / Autocuidado de hombres con priapismo y enfermedad falciforme / Autocuidado de homens com priapismo e doença falciforme

ABSTRACT Objective: To identify self-care demands of men with sickle cell disease and priapism and describe self-care measures in light of Orem's Self-Care Theory. Method: This is a descriptive exploratory study with qualitative approach conducted with nine men with a history of sickle cell disease and priapism. Data were analyzed using Orem's Self-Care Theory. Results: Some demands were identified: from universal self-care - difficulty in social interaction and solitude, changes in self-image, self-esteem and sexual activity; from development - the experience with priapism and little knowledge about the pathophysiology of the disease; regarding health deviations - pain crises. Conclusion: Orem's theory allowed to identify self-care demands, which are essential for the nursing care provided for men with priapism. Nursing has an essential role in the measures for the different demands presented.

Priapismo neonatal. Reporte de un caso y revisión de literatura / Neonatal priapism. Case report and literature review

Introducción: El priapismo se puede describir como una erección peneana prolongada y persistente con duración de más de 4 horas y no asociada con el interés sexual o la estimulación. El priapismo neonatal es una rara entidad con pocos casos reportados hasta la fecha (19 casos hasta el 2017 incluyendo el presente). La experiencia actual en priapismo neonatal se basa prin-cipalmente en informes de casos individuales similares. Por lo tanto, la evaluación, el tratamiento y el seguimiento son desaiantes en la práctica de urología pediátrica. Caso clínico: se presenta paciente masculino, recién nacido de 20 días de vida por cuadro de dermatitis del pañal coinfectada, se ingresa y se brinda manejo, al segundo día de su hospitalización presenta priapismo que resuelve 5 días después. Discusión: El priapismo neonatal de alto lujo es el más común en esta etapa. El conocimiento del cuadro de pria-pismo permite realizar un enfoque adecuado, aplicar de forma sistemática las exploraciones y establecer un diagnóstico y tratamiento para prevenir sus complicaciones. Conclusión: No se conoce una causa exacta de esta patología, por lo que el manejo será en la mayoría de los casos conservador...(AU)

Penile Doppler ultrasonography revisited

Penile Doppler ultrasonography is a high-performing, noninvasive or minimally-invasive imaging modality that allows the depiction of the normal anatomy and macroscopic pathologic changes in real time. Moreover, functional changes in penile blood flow, as seen in erectile dysfunction (ED), can be analyzed using color Doppler ultrasonography (CDUS). This review article describes the normal sonographic anatomy of the penis, the sonographic technique for evaluating ED, the normal phases of erection, and the various causes of ED. Additionally, we describe the interpretation of different parameters and findings on penile CDUS for the diagnosis and classification of ED, priapism, and Peyronie disease.

Application value of ultrasonography in penile diseases / 中华男科学杂志

Penile disease is one of the male urological diseases. Although the penis is a small organ, once the problem occurs, it often brings great trouble to the patient. Therefore, the accurate diagnosis of penile disease is particularly important. High-frequency ultrasonography, with its advantages of noninvasiveness, safety, low cost, easy operation and reproducibility, can clearly show the structure and blood flow of the penis and has a significant value in the diagnosis and follow-up of penile diseases such as vascular erectile dysfunction, priapism, penile injury, penile neoplastic and non neoplastic nodules. Meanwhile, the development of new technologies such as shear wave elastography (SWE) and contrast enhanced ultrasound (CEUS) has made up for the shortcomings of traditional ultrasound imaging, expanded the application of ultrasound in penile diseases, and improved the efficiency of ultrasound diagnosis of the diseases. This article focuses on the application value of ultrasound in erectile dysfunction, priapism, penile cavernous injury and penile tubercle, as well as the latest progress in such new technologies as SWE and CEUS applied to penile diseases.

Role of Penile Prosthesis in Priapism: A Review

Ischemic priapism is a urological emergency that has been associated with long-standing and irreversible adverse effects on erectile function. Studies have demonstrated a linear relationship between the duration of critically ischemic episodes and the subsequent development of corporal fibrosis and irreversible erectile function loss. Placement of a penile prosthesis is a well-established therapeutic option for the management of erectile dysfunction secondary to ischemic priapism, and will be the focus of this review. Review of the current literature demonstrates a growing utilization of penile prostheses in the treatment of erectile dysfunction secondary to ischemic priapism. Unfortunately, there is a paucity of randomized-controlled trials describing the use of prosthesis in ischemic priapism. As a result, there is a lack of consensus regarding the type of prosthesis (malleable vs. inflatable), timing of surgery (acute vs. delayed), and anticipated complications for each approach. Both types of prostheses yielded comparable complication rates, but the inflatable penile prosthesis have higher satisfaction rates. Acute treatment of priapism was associated with increased risk of prosthetic infection, and could potentially cause psychological trauma, whereas delayed implantation was associated with greater corporal fibrosis, loss of penile length, and increased technical difficulty of implantation. The paucity of high-level evidence fuels the ongoing discussion of optimal use and timing of penile prosthesis implantation. Current guidance is based on consensus expert opinion derived from small, retrospective studies. Until more robust data is available, a patient-centered approach and joint decision-making between the patient and his urologist is recommended.

Priapismo en la drepanocitosis. Diagnóstico y opciones terapéuticas / Priapism in sickle cell disease. Diagnosis and therapeutics options

El priapismo es una complicación de la anemia drepanocítica y se define como una erección prolongada, dolorosa y persistente del pene de más de 4 horas de duración sin estimulación sexual asociada. El 95 por ciento de las crisis de priapismo en estos pacientes es de tipo isquémico o de bajo flujo y constituyen una emergencia médica que, de no diagnosticarse y tratarse adecuadamente, provoca necrosis del tejido y disfunción eréctil. En este trabajo se revisan el diagnóstico y las opciones terapéuticas actuales y futuras de esta grave complicación(AU)

Priapism is a common complication of sickle cell disease and it is characterized by a prolonged, painful and persistent erection of the penis lasting more than 4 hours without associated sexual stimulation. The 95 percent of priapism crisis in these patients is ischemic type and represents a medical emergency that can provoke erectile tissue necrosis and erectile dysfunction if not treated properly. In this paper we reviewed the diagnosisand the current and perspectives therapeutic options of this severe complication(AU)

Daily use of phosphodiesterase type 5 inhibitors as prevention for recurrent priapism / Prevenção do priapismo recorrente com a utilização diária de inibidores da fosfodiesterase tipo 5

Summary Objective: The pathogenesis of recurrent priapism is currently being investigated based on the regulation of the phosphodiesterase 5 (PDE5) enzyme. We explored the daily use of PDE5 inhibitors to treat and prevent priapism recurrences. Method: We administered PDE5 inhibitors using a long-term therapeutic regimen in seven men with recurrent priapism, with a mean age of 29.2 years (range 21 to 35 years). Six men (85.7%) had idiopathic priapism recurrences and one man (24.3%) had sickle cell disease-associated priapism recurrences. Tadalafil 5 mg was administered daily. The mean follow-up was 6.6 months (range 3 to 12 months). Results: Daily long-term oral PDE5 inhibitor therapy alleviated priapism recurrences in all patients. Five (71.4%) had no episodes of priapism and two (28.6%) referred decrease in their episodes of priapism. All patients referred improvement in erectile function. Conclusion: These findings suggest the hypothesis that PDE5 dysregulation exerts a pathogenic role for both sickle cell disease-associated priapism and for idiopathic priapism, and that it offers a molecular target for the therapeutic management of priapism. These preliminary observations suggest that continuous long-term oral PDE5 inhibitor therapy may treat and prevent recurrent priapism.

Resumo Objetivo: Uma das teorias propostas para explicar a etiologia do priapismo recorrente está baseada no mecanismo de regulação da fosfodiesterase tipo 5. Estudamos o uso diário dos inibidores de fosfodiesterase tipo 5 no tratamento e na prevenção do priapismo recorrente. Método: Sete homens com diagnóstico de priapismo recorrente, com idade média de 29,5 anos (21 a 35 anos), utilizaram inibidor de fosfodiesterase tipo 5 em dose diária (tadalafila 5 mg/dia) por período prolongado. Seis homens (85,7%) apresentavam priapismo recorrente de etiologia idiopática, e um homem (24,3%), de etiologia associada à anemia falciforme. O seguimento médio foi de 6,6 meses (3 a 12 meses). Resultados: Todos os pacientes se beneficiaram com a utilização de inibidores de fosfodiesterase tipo 5. Cinco (71,4%) não apresentaram nenhum episódio de priapismo e dois (28,6%) relataram diminuição dos episódios. Todos os pacientes relataram melhora da função erétil. Conclusão: Estes achados sugerem que a hipótese do mecanismo de regulação da fosfodiesterase tipo 5 exerce papel importante na patogenia do priapismo recorrente. O uso contínuo e diário de inibidores da fosfodiesterase tipo 5 pode ser uma opção no tratamento do priapismo recorrente.

El priapismo en la Leucemia Mieloide Crónica Hallazgos radiológicos en casos de Leucemia Mieloide Crónica que se presentaron con priapismo / 7 PRIAPISM IN CHRONIC MYELOID LEUKEMIA : IMAGING FINDINGS IN CASES OF CHRONIC MYELOID LEUKEMIA WHO PRESENTED WITH PRIAPISM

El priapismo es una emergencia urológica que debe ser diagnosticada y tratada apropiadamente. Específicamente en casos conocidos de leucemia el pene turgente doloroso debe hacer surgir la sospecha de priapismo de primera movida y el Doppler peneano debe ser la mera línea de modalidad de imágenes. Esta información debe ser transmitida al paciente y al departamento clínico emergentológico

Priapism is an urological emergency and must be diagnosed and treated appropriately. Specifically in known cases of leukemia painful turgid penis should raise suspicion of priapism in first hand and penile Doppler should be the first line of imaging modality. This information should be forwarded to patient and emergency department clinician

Prognostic factors and outcome of management of ischemic priapism in Zaria, Nigeria

Objectives: The objective of this study was to determine the nuances of management, prognostic factors, and outcome of ischemic priapism in patients seen at Ahmadu Bello University Teaching Hospital, Zaria, Nigeria. Patients and Methods: We retrospectively studied the case notes of all patients managed for ischemic priapism in the Ahmadu Bello University Teaching Hospital, Zaria, over a period of 10 years (2006­2015). The data extracted included patients' age, occupation, duration of painful penile erection, and previous episodes. Addition information including precipitating factors, hemoglobin genotype, treatment, and complications was also retrieved. Data obtained were analyzed using SPSS version 20. Results: The records of a total of forty patients managed for priapism over the period under review were retrieved. Thirty-three (82.5%) of these patients had an operative intervention. The mean age was 23.7 years with a range of 8­53 years. Sixty percent of patients were young adults in their third decade of life. The minimum duration of erection at presentation was 18 h and a maximum period of 10 days with a mean of 105.5 h (4 days). Thirty-three patients (82.5%) had sickle cell anemia (HbSS). Erectile dysfunction (ED) accounted for 60% of all forms of postpriapism complications. Five patients (12.5%) had residual tumescence from fibrosis, and three patients had recurrence outside the immediate postoperative period. Duration of symptoms before surgical intervention, SSA and previous episodes were the most important prognostic factors. Conclusion: Priapism is a disease of the young, mostly sickle cell anemic patients. Late presentation remains the norm in our environment, hence a higher incidence of ED. The distal penile shunt is an effective means of achieving detumescence even with failed conservative management. Favorable outcome is highly dependent on the duration of erection and early intervention

Fisiopatología del priapismo en el paciente con anemia drepanocítica / Physiopathology of priapism in sickle cell anaemia patients

La anemia drepanocítica es una enfermedad con un alto índice de morbilidad que afecta la calidad de vida de los pacientes que la padecen. El priapismo es una complicación frecuente de la enfermedad y se define como una erección dolorosa, prolongada y persistente del pene de más de 4 horas de duración,sin estimulación sexual asociada. El 95 por ciento de las crisis de priapismo en el paciente con anemia drepanocítica son de tipo isquémico o de bajo flujo. En este trabajo se revisan los nuevos mecanismos moleculares que explican la patogenia del priapismo isquémico y que son la base de futuras posibles dianas terapéuticas para su tratamiento(AU)

Sickle cell anaemia (SCD) is a disorder with a high index of morbidity, affecting the quality of life of these patients. Priapism is a common complication of SCD and it is characterized by a prolonged and persistent erection of the penis lasting more than 4 hours without associated sexual stimulation. The 95 percent of priapism crisis in SCD patients are ischemic type. In this paper we review the new molecular mechanisms implicated in the pathogenesis of ischemic priapism and provide the basis for potential future therapies(AU)

Recurring priapism may be a symptom of voiding dysfunction – case report and literature review

ABSTRACT Recurring priapism is rare in pre-pubertal children and may be attributed to multiple causes. We propose that voiding dysfunction (VD) may also justify this symptom and detail a clinical case of recurring stuttering priapism associated to overactive bladder that completely resolved after usage of anticholinergics and urotherapy. Sacral parasympathetic activity is responsible for detrusor contraction and for spontaneous erections and a relationship between erections and bladder status has been proved in healthy subjects (morning erections) and models of medullar trauma. High bladder pressures and/or volumes, voiding incoordination and posterior urethritis can potentially trigger reflex erections.

The possible protective effects of dipyridamole on ischemic reperfusion injury of priapism

ABSTRACT Purpose To investigate the protective effects against ischemia reperfusion injury of dipyridamole in a model of induced priapism in rats. Materials and Methods Twenty-four male Sprague-Dawley rats were divided into four groups, control, P/R, P/R+DMSO and P/R+D. 3ml blood specimens were collected from vena cava inferior in order to determine serum MDA, IMA, TAS, TOS and OSI values, and penile tissue was taken for histopathological examination in control group. Priapism was induced in P/R group. After 1h, priapism was concluded and 30 min reperfusion was performed. In P/R+DMSO group 1ml/kg DMSO was administered intraperitoneally 30 min before reperfusion, while in P/R+D group 10mg/kg dipyridamole was administered intraperitoneally 30 min before reperfusion. Blood and penis specimens were collected after the end of 30 min reperfusion period. Sinusoidal area (µm2), tears in tunica albuginea and injury parameters in sinusoidal endothelium of penis were investigated. Results Histopathological examination revealed no significant changes in term of sinusoidal area. A decrease in tears was observed in P/R+D group compared to P/R group (p<0.05). Endothelial injury decreased in P/R+D group compared to P/R group (p>0.05). There were no significant differences in MDA and IMA values between groups. A significant increase in TOS and OSI values was observed in P/R+D group compared to P/R group. A significant decrease in TAS levels was observed in P/R+D group compared to the P/R group. Conclusions The administration of dipyridamole before reperfusion in ischemic priapism model has a potential protective effect against histopathological injury of the penis.

Does platelet activity play a role in the pathogenesis of idiopathic ischemic priapism?

ABSTRACT Purpose Mean platelet volume (MPV) is used to measure platelet size and is defined as a potential marker of platelet reactivity. Higher MPV levels have been defined as a risk factor for increased incidence of intravascular thrombosis and its associated diseases. We aimed to determine whether a relationship exists between the MPV and veno-occlusive component of idiopathic ischemic priapism (IIP). Materials and methods Between 2010 and 2014, 38 subjects were analyzed in two groups. One was composed of 15 patients with diagnosis as IIP in our institute, and the other contained 23 healthy control subjects. Complete blood count reports were retrospectively evaluated in both groups. MPV, platelet count (PLT), platelet distribution width (PDW), white blood cells (WBC), red blood cells (RBC), hemoglobin (Hb), reticulocyte distribution width (RDW) were measured in both groups. : Results The mean ages were similar in IIP patients (45.86±15.82) and control subjects (47.65±10.99). The mean MPV values of IIP patients were significantly higher than control subjects (p<0.05). In contrast, also PLT counts were significantly lower in IIP patients, compared to control subjects (p<0.05). The mean hemoglobin and WBC values were significantly lower in control group (p<0.05). There was no significant difference of RBC, PDW and RDW values in both groups. Conclusions We found that the MPV was significantly higher in IIP patients compared to control subjects. The high MPV levels may have contributed to the veno-occlusive etiopathogenesis of IIP disease. We strongly suggest further prospective studies to recommend the use of MPV in routine practice.

Ischemic Priapism in South-East Nigeria: Presentation; Management Challenges; and Aftermath Issues

Context: Ischemic priapism is the more common variety of priapism and often presents late. Outcome is largely dependent on the duration of ischemia. Aims: To determine the etiology; presentation; management; and outcome of ischemic priapism.
