Priapism in children: an experience of the modified Winter procedure.

BACKGROUND: Priapism in children is a rare disease, which seldom presents during the pediatric surgery practice. It is, however, a surgical and urological emergency. Early diagnosis and prompt management can prevent the devastating sequelae of this potentially fatal condition. MATERIALS AND METHODS: A prospective study was conducted between March 1st, 2007 and February 28th, 2019 at the Department of Pediatric Surgery, Khyber Teaching hospital, Peshawar. All the patients between 3 and 15 years of age, with the diagnosis of priapism, were enrolled in the study with ethical approval. RESULTS: A total of ten patients were enrolled in the study period from March 1st, 2007 to February 28th, 2019. The age ranged between 3 and 15 years and the mean age of presentation was 8 years. The mean duration of symptoms was 4 h. The mean hospital stay was 4 days. The modified Winter procedure by creating a corporoglanular shunt was performed in all cases. Successful detumescence was achieved in eight patients, while two patients needed further detumescence and manual evacuation. Symptomatic relief was achieved in all the children. CONCLUSION: Priparism in children is a rare urological emergency that can lead to permanent erectile dysfunction if prompt medical intervention is not done. The modified Winter procedure technically is a less invasive procedure to achieve satisfactory clinical outcome in terms of achieving good erectile functions.

Pretreatment screening and counseling on prolonged erections for patients prescribed trazodone.

PURPOSE: We examined whether patients are appropriately screened for previous prolonged erections or priapism and counseled about trazodone complications, specifically prolonged erections and priapism, prior to trazodone treatment. MATERIALS AND METHODS: We identified patients under the age of 50 on trazodone as of February 27, 2019 at the VA New Jersey Health Care System. Patients were asked about information provided to them prior to medication initiation, occurrence of prolonged erections/priapism, and reporting rate of side effects. RESULTS: Two hundred and twenty nine out of five hundred and twenty four male patients agreed to participate in the study. Forty three out of two hundred and twenty nine of patients were informed about the side effects of prolonged erections and 37/229 of patients were informed of risk of priapism prior to treatment. Only 17/229 of patients were asked if they had had any episodes of prolonged erection or priapism in the past. Eighteen patients developed prolonged erection while taking trazodone. Only 5/18 patients who had developed prolonged erections informed their physicians. CONCLUSIONS: Only a fraction of patients were properly screened for previous prolonged erections or priapism and properly informed about the side effects of trazodone. Urologist should better educate trazodone prescribers, such as family medicine and psychiatric colleagues, regarding the side effects of trazodone. It is imperative that prescribing physicians appropriately screen and educate patients prior to trazodone initiation and instruct patients to report any treatment side effects to avoid potential long-term adverse outcomes.

[When a urological emergency indicates an internal medical crisis : Priapism as the first clinical manifestation of leukemia]. / Wenn ein urologischer Notfall auf eine internistische Krise hinweist : Priapismus als klinische Erstmanifestation einer Leukämie.

Priapism as a sign of a severe hematological disease is a rare event, which has to be considered as both a urological and a hematological emergency that requires immediate treatment. This article describes a clinical case of priapism as the first clinical manifestation of a hitherto undiagnosed chronic myeloid leukemia (CML) and discusses the results of a literature review on this topic.

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)

Malignant Priapism - What Do We Know About It?

Malignancy as an etiological factor involved in priapism pathogenesis is rare. Malignant priapism (MP) can arise as a result of penile tumor invasion, either from primary penile tumors or from metastatic penile tumors, or due to hematological malignancies. Non-urological penile metastases are associated with significant worse prognosis compared to urological penile metastases, the appearance of priapism in such cases affecting even more the prognosis and the survival of these patients. Patients diagnosed with hematological malignancies and priapism present significant higher survival rates compared to those who develop MP in the context of a non-hematological malignancy, this being related to the fact that hematological malignancies are more sensitive to chemo- and radiotherapy. Most malignant priapism cases are ischemic; therefore the management should be based on the initial steps of the IP therapeutic protocol. Considering the trigger factor that has led to the priapic event specific oncologic treatment can be added as well.

Neurofibromatosis-1 and Rhabdomyosarcoma: An Unusual Recurrence.

Neurofibromatosis-1 has a known increased risk of malignancy with rhabdomyosarcoma occurring in up to 6% of patients. Here we report on an 8-year-old male with a history of Neurofibromatosis-1 and previously treated stage 3, group III bladder/prostate embryonal rhabdomyosarcoma (diagnosed at 18 months old) who presented with penile swelling concerning for priapism. Imaging and subsequent biopsy confirmed embryonal rhabdomyosarcoma of the penile corporal bodies. Penile rhabdomyosarcoma is exceedingly rare, with less than 15 case reports in the literature. Our patient received chemoradiation per D9803 with organ preserving local control and is doing well 3 months after treatment.

[Ischemic Priapism Associated with Essential Thrombocythemia : A Case Report].

A 71-year-old man visited a local urologist with the complaint of continuous painful erection for three days. Penile cavernosal blood data showed acidosis and hypoxia. Thus he was diagnosed with ischemic priapism. After penile aspiration and injection of phenylephrine, erection was temporary improved. The blood platelet count was 94.5×104/µl and myeloproliferative disease was suspected. He was referred to our hospital and visited us the following day. Since priapism relapsed, we aspirated corpus cavernosum of the penis and injected phenylephrine which was successful. A bone marrow biopsy and genetic test were performed at the department of hematology and the diagnosis of essential thrombocythemia with JAK2 gene mutation was confirmed. By treatment with hydroxyurea, the blood platelet count decreased without priapism recurrence.

Penile gangrene: an unusual complication of malignant priapism in a patient with renal cell carcinoma.

A 68-year-old man presented with priapism and penile gangrene. The patient had no history of penis trauma or medications for erectile dysfunction. Corpus cavernosa aspiration cytology were positive for malignant cells. Total penectomy was performed. Enhanced chest and abdominal computed tomography showed a left renal tumor with pulmonary and hepatic metastases. Ultrasound-guided renal biopsy showed clear cell renal cell carcinoma.

[Priapism: Diagnosis and management]. / Le priapisme : diagnostic et prise en charge.

OBJECTIVE: Our aim was to present a synthesis on the diagnosis and treatment of priapism. METHODS: For this purpose, a literature search was performed through PubMed to analyze literature reviews and guidelines regarding priapism. RESULTS: Priapism is an erection that persists more than 4hours. There are 3 types of priapism: ischemic priapism, non-ischemic priapism and recurrent (stuttering) priapism. Ischemic priapism, often idiopathic, is the most frequent. When diagnosed, an urgent management is required to limit erectile dysfunction. Sickle-cell patients are prone to have ischemic and stuttering priapism. Non-ischemic priapism usually occurs after perineal trauma. Priapism management depends on the type of priapism. Medical treatment (corporal aspiration and injection of sympathomimetics) then if failed, surgery are indicated for ischemic priapism. The persistence of a non-ischemic priapism most likely requires a radiologic embolization. CONCLUSION: Priapism is a condition that often requires emergency treatment to spare erectile function. It appears crucial to know this condition and its management.

[Considerations on priapism].

Priapism is a rare pathological penile erection, and there are some inadequacies in its definition, classification, diagnosis, and therapeutic strategies. In this article, we sum up our years of experience with priapism and put forward some new views and ideas about its definition, classification, pathophysiologic process, pathological change, diagnostic essentials, therapeutic measures, indications of successful treatment, and post-therapeutic rehabilitation of erectile function. We also describe the clinical features, diagnosis and treatment of some special types of priapism, such as intermittent seizure, sleep-related painful erection, and tumor-related priapism, hoping to help urologists and andrologists in the further understanding and management of priapism.

[Priapism is an emergency]. / Priapisme is een spoedgeval.

The term priapism describes erections of >4 hours that arise in the absence of or last well beyond sexual stimulation. Ischaemic priapism is the most common form and treatment success is strongly dependent on the duration of priapism. The aetiology is widely variable as a result of which several specialisms can be confronted with this condition. Over the past few years, urologists increasingly have to deal with patients who do not suffer from erectile dysfunction, but nevertheless use intracavernous injections with priapism as a result. These men are often reluctant to see a doctor due to shame and ignorance, which often leads to delayed treatment. According to current guidelines, early prosthesis implantation is recommended if the priapism lasted >36 hours. Treatment of stuttering priapism should be focused on prevention of subsequent episodes. Non-ischaemic priapism generally follows a mild course and can initially be approached conservatively.

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)

Urologic Emergencies.

Urologic emergencies can involve the kidneys, ureters, bladder, urethra, penis, scrotum, or testicles. History and physical examination are essential to diagnosis, whereas imaging is increasingly used to confirm diagnoses. Acute urinary retention should be relieved with Foley placement. Penile emergencies include paraphimosis, which can be treated by foreskin reduction, whereas penile fracture and priapism require urologic intervention. Fournier gangrene and testicular torsion are scrotal emergencies requiring emergent surgery. Nephrolithiasis, although painful, is not an emergency unless there is concern for concomitant urinary tract infection, both ureters are obstructed by stones, or there is an obstructing stone in a solitary kidney.

BAUS consensus document for the management of male genital emergencies: priapism.

Male genital emergencies relating to the penis and scrotum are rare and require prompt investigation and surgical intervention. Clinicians are often unfamiliar with the management of these conditions and may not work in a specialist centre with on-site expertise in genitourethral surgery. A series of consensus statements have been developed by an expert consensus committee comprising members of the BAUS Section of Andrology and Genitourethral Surgery together with experts from urology units throughout the UK. Priapism requires prompt assessment and treatment and these consensus statements provide guidance for UK practice.

Nonischemic Priapism in Childhood: A Case Series and Review of Literature.

INTRODUCTION: Nonischemic priapism (NIP) in childhood is a very rare affection. In the literature, patients with NIP are described mainly incidental after perineal trauma. Many of them underwent embolization of either internal pudendal artery or bulbocavernosal arteries. PATIENTS AND METHODS: We report on six boys between 4 and 13 years of age with NIP, treated at our institution between 2008 and 2014. Color Doppler ultrasound (CDU) was performed in all patients as emergency diagnostic evaluation. Patients were treated conservatively, including bed rest, local cooling, and perineal compression. History, etiological factors, clinical findings, diagnostics, and follow-up are presented. RESULTS: Out of the six patients, only one boy had a history of perineal injury with subsequent arteriocavernosal fistula, revealed in CDU. Five patients were circumcised, and one of them suffered from thalassemia minor, but no other underlying disease or etiological factors could be found. In all patients, normal to high blood flow velocities were detected in the cavernosal arteries. Detumescence started with nonoperative treatment within 24 hours in five boys and in one patient with recurrent priapism after 1 week. All six patients remained painless without evidence for an ischemic priapism. None of them suffered from relapse and further erections were observed during follow-up from 3 to 87 months. CONCLUSION: In contrast to the literature, five out of six boys developed NIP without a previous perineal trauma. The etiology of idiopathic NIP in childhood remains unclear; however, circumcision may play a role as a conditional factor. One etiological thesis could be the release of the neurotransmitter nitric oxide after stimulation of the corpora cavernosa. Conservative treatment proved to be successful in all six patients. During a median follow-up of 55 months (3-87 months), none of the patients showed signs of erectile dysfunction.

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.

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)

Intermittent Projectile Urethraggia: An Unusual Sequela of a Skateboarding Accident in an Adolescent Male.

Our patient suffered a perineal straddle injury, resulting in right cavernosal artery pseudoaneurysm in combination with a cavernosal-urethral fistula. The urethra failed to heal after several weeks, and the patient presented with severe intermittent urethral bleeding. The pseudoaneurysm was successfully treated by coil embolization, with resolution of the bleeding. The patient recovered completely, with normal erectile and voiding function. This type of injury is very rare in the literature: traumatic cavernosal arterial pseudoaneurysm is known to cause high flow priapism, but in this case additional cavernosal-urethral fistula resulted in a severe urethraggia. This is the only case, to our knowledge, of delayed urethral bleeding from cavernosal artery pseudoaneursym in combination with a cavernosal-urethral fistula.
