Máculas melanóticas del pene. Presentación de un caso

Las máculas melanóticas del pene son lesiones idiopáticas, benignas, poco frecuentes, en ocasiones multifocales, heterocrómicas e irregulares, que deben diferenciarse del melanoma de mucosas. Se presenta el caso de un paciente con lesiones pigmentadas en el pene, asintomáticas, pero que se habían incrementado en número. Con la ayuda de la dermatoscopia y la histopatología, se llegó al diagnóstico de máculas melanóticas del pene. Aunque son reducidas las opciones terapéuticas en el medio descrito, la trascendencia del diagnóstico de esta dermatosis radica en descartar la posibilidad de su malignidad.

Melanotic macules of the penis are idiopathic, benign, rare lesions, sometimes multifocal, heterochromic and irregular, which must be differentiated from mucosal melanoma. A patient with asymptomatic pigmented lesions on the penis, but which had increased in number is presented. With dermoscopy and histopathology test, the diagnosis of melanotic macules of the penis was reached. Although the therapeutic options in the described environment are limited, the significance of this dermatosis diagnosis lies in ruling out the possibility of its malignancy.

Epidemiological study of penile cancer in a northeastern state - Brazil / Estudo epidemiológico do câncer de pênis em um estado do Nordeste - Brasil

ABSTRACT Objective: to trace the clinical and epidemiological profile of penile cancer in Rio Grande do Norte/Brazil and relate them to data published in the literature. Methods: a cross-sectional study was conducted with 94 patients diagnosed with penile cancer in 2011-2018, treated at the Liga Norte Riograndense Contra o Cancer. Results: all patients were diagnosed with squamous cell carcinoma, mainly aged over 50 years, from the states interior, brown, illiterate, or with incomplete primary education. At diagnosis, 68% of patients were classified as having tumors =T2, and 30% had lymph node involvement. Distant metastases were detected in 2.1% of patients at diagnosis. Most patients received the diagnosis in the initial phase of the disease, but 20.2% were diagnosed in stage IV. Partial penectomy was the most performed surgery, and 10% of patients relapsed, mainly in the lymph nodes (87.5%). The mean follow-up of the patients was 18 months, with an estimated overall survival at five years of 59.1%. However, 25% of patients were followed up for up to 3 months, losing follow-up. Conclusion: the State of Rio Grande do Norte has a high incidence of penile cancer with a high frequency of locally advanced tumors at diagnosis and in younger patients younger than 50. Furthermore, socioeconomic factors interfere with early diagnosis and hinder access to specialized services.

RESUMO Objetivo: traçar o perfil clínico e epidemiológico do câncer de pênis no Rio Grande do Norte/Brazil e relacioná-los com dados publicados na literatura. Métodos: realizou-se estudo transversal de 94 pacientes diagnosticados com câncer de pênis no período de 2011-2018, tratados na Liga Norte Riograndense Contra o Câncer. Resultados: todos os pacientes foram diagnosticados com carcinoma espinocelular, principalmente com idade acima dos 50 anos, provenientes do interior do estado, pardos, analfabetos ou com ensino fundamental incompleto. Ao diagnóstico, 68% dos pacientes foram classificados com tumores =T2 e 30% possuiam envolvimento linfonodal. Metástases à distância foram detectadas em 2,1% dos pacientes ao diagnóstico. A maioria dos pacientes recebeu o diagnóstico na fase inicial da doença, mas 20,2% foram diagnosticados em estádio IV. Penectomia parcial foi a cirurgia mais realizada e 10% dos pacientes recidivaram, principalmente para linfonodos (87,5%). A média de seguimento dos pacientes foi de 18 meses, apresentando estimativa de sobrevida global em 5 anos de 59,1%. No entanto, 25% dos pacientes foram acompanhados por até 3 meses, perdendo o seguimento. Conclusão: o Estado do Rio Grande do Norte apresenta elevada incidência de câncer de pênis com alta frequência de tumores localmente avançados ao diagnóstico, assim como em pacientes mais jovens, menores que 50 anos de idade. Outrossim, o fator socioeconômico interfere no diagnóstico precoce e dificulta o acesso a serviços especializados. .

Introduction: Buried penis is a rare pathology related to the reduction of penile length. It is described with a higher incidence in children, but it also affects adults. This population is mainly associated with obesity and fat accumulation in the suprapubic region, being considered a pathology that is difficult to manage and treat. Surgical intervention is the basis of treatment, and the main objective is the return of urinary and sexual function. Multiple surgical techniques are described for reconstruction in patients with buried penis and must be adapted to the characteristics presented by the patient. Case Report: This article reports the surgical technique of dermolipectomy associated with the fixation of the base of the penis in pubic symphysis and a partial skin graft to approach a patient with a buried penis. Conclusion: The presented technique showed good functional postoperative results due to clinical improvement of the patients' initial complaints and aesthetic ones, verbalized by the patient and the legal guardian due to the patient's low cognitive level.

Application of high frequency ultrasound in the diagnosis of closed penile cavernous rupture / 中国医师杂志

Objective:To explore the diagnostic value of high frequency ultrasound in the diagnosis of closed penile cavernous rupture.Methods:The ultrasonic examination data of 8 patients with closed penile cavernous rupture treated in Union Medical College Affiliated to Tongji Medical College of Huazhong University of Science and Technology from August 2016 to May 2021 were retrospectively analyzed, and the high-frequency ultrasonic image features were analyzed.Results:Among the 8 patients with closed penile cavernous rupture, 6 were located at the distal end of the corpus cavernosum, one was located at the middle of the corpus cavernosum, and one was located at the proximal end of the corpus cavernosum. All of them were unilateral penile cavernosum rupture, 3 on the left side and 5 on the right side. In all 8 cases, the white membrane of the corpus cavernosum of the penis was continuously interrupted, and the broken end could be clearly displayed. The largest white membrane breach was 16.1 mm, and the smallest was 2.1 mm. Hematoma formed around the rupture of the tunica albuginea of the penis corpus cavernosum, and the maximum range of hematoma was 40.3 mm×15.4 mm, the minimum range of hematoma was 7.9 mm×5.6 mm.Conclusions:High frequency ultrasound is convenient, rapid and accurate, and can be used as the first choice of auxiliary examination for closed penile cavernous rupture.

Penile emergencies: a review of the main conditions / Emergências penianas: uma revisão das principais afecções

Abstract Acute penile conditions, which typically have a traumatic, vascular, or infectious etiology, are rather uncommon and often require prompt medical evaluation. Penile emergencies can be treated conservatively or surgically, and their management often relies on the results of imaging examinations. Because of its high spatial resolution and wide availability, as well as the fact that it does not involve the use of ionizing radiation, ultrasound is the imaging modality of choice in the initial evaluation of penile emergencies. Inconclusive cases can be further evaluated with magnetic resonance imaging. The main purpose of this pictorial essay is to review the main penile emergencies, by presenting illustrative cases, focusing on radiologic findings, and discussing the roles played by the various imaging methods.

Resumo As condições agudas do pênis são raras, geralmente relacionadas a causas traumáticas, vasculares ou infecciosas, e muitas vezes requerem avaliação médica imediata. As emergências penianas podem ter tratamento conservador ou cirúrgico e muitas vezes dependem dos exames de imagem. A ultrassonografia é a modalidade de imagem de escolha na avaliação inicial das emergências penianas, em virtude da alta resolução espacial, ampla disponibilidade e ausência de radiação ionizante desse método. A ressonância magnética deve ser considerada em casos inconclusivos, oferecendo maior campo de visão e detalhes precisos sobre o local e extensão das lesões. O principal objetivo deste ensaio iconográfico é revisar as principais emergências do pênis por meio de casos ilustrativos, com foco nos achados radiológicos e no papel dos métodos de imagem.

Extracorporeal Shock Wave Therapy in Peyronie's Disease: Clinical Efficacy and Safety from a Single-Arm Observational Study

PURPOSE: In this study, we aimed to determine the role of extracorporeal shockwave therapy (ESWT) in the management of Peyronie's disease (PD). MATERIALS AND METHODS: A total of 325 patients suffering from PD were enrolled in this single-arm clinical study. All patients were received ESWT using a schedule of 1 treatment/wk. Penile curvature was measured by a goniometer after intracavernosal drug-induced erection using Alprostadil. Plaque size was measured with a ruler and sexual function assessed by the international index of erectile function (IIEF)-15 score. Severity of erectile dysfunction was classified as severe (IIEF-15 ≤10), moderate (IIEF-15 between 11 and 16), or mild (IIEF-15 between 17 and 25). Results were evaluated at baseline and 3 months after the treatment. RESULTS: All the patients completed the study protocol. Median age was 59.0 years (55.0–64.0 years). After treatment, the median (interquartile range, IQR) plaque size reduced from 1.78 cm2 (1.43–2.17 cm2) to 1.53 cm2 (1.31–1.96 cm2) (p<0.001); the median (IQR) penile length in erection increased from 13.0 cm (12.0–14.0 cm) to 14 cm (13.0–15.0 cm) (p<0.001) and the median (IQR) penile curvature from 30.4° (22.2°–35.4°) to 25.0° (20.2°–30.4°) (p<0.001). We also observed a decrease in pain assessed by visual analogue scale (7 vs. 3; p<0.001), an improvement in each of the IIEF sub-domains (p<0.001) and an improvement in all three PD questionnaire domains (p<0.001). CONCLUSIONS: Based on our findings, ESWT could be considered a safe and efficient minimally invasive option for the management of the patients suffering from PD.

Bilateral fracture of corpora cavernosa with complete rupture of the anterior urethra: Case report and review of recent findings for surgical management / Fractura bilateral de cuerpos cavernosos con sección completa de uretra anterior. Reporte de caso y revisión de conceptos actuales sobre el manejo quirúrgico

Abstract Introduction: Penile fracture is a rare urological emergency associated in up to 30% of cases with injury to the anterior urethra. Recent data suggest that early surgical intervention is the best treatment strategy. This investigation describes a case of bilateral corpora cavernosa injury associated with complete rupture of the anterior urethra and presents current concepts about its management. Case presentation: 39-year-old man with bilateral corpora cavernosa injury and complete rupture of the anterior urethra, who received early surgical treatment with satisfactory early clinical outcomes. A literature review was made in PubMed and Embase, limiting the search to scientific articles published in the past 10 years using the MeSH terms "Penile diseases", "Genital diseases, male", "Wounds and injuries". Some references were included given their clinical relevance. In this case, similar to international experiences, early surgical management of corpora cavernosa fractures allowed achieving adequate clinical outcomes in the patient. Conclusions: The diagnosis of penile fracture is based on clinical findings. Early surgical management should be considered as a therapy of choice. Conservative management has a higher complication rate versus early surgical management. The case described here had an adequate clinical evolution after 3 months of follow-up.

Resumen Introducción. La fractura de cuerpos cavernosos es una urgencia urológica que se asocia hasta en 30% de los casos a lesión de la uretra anterior. Datos recientes postulan la intervención quirúrgica temprana como la mejor estrategia de tratamiento. La presente investigación describe un caso de lesión bilateral de cuerpos cavernosos asociada a sección completa de uretra anterior y define conceptos actuales sobre su manejo. Presentación del caso. Hombre de 39 años con fractura bilateral de cuerpos cavernosos y sección completa de uretra anterior, quien recibió tratamiento quirúrgico temprano con resultados clínicos tempranos satisfactorios. Se realizó una revisión de la literatura en PubMed y Embase limitando la búsqueda a artículos científicos publicados en los últimos 10 años y utilizando los términos MeSH "Penile diseases", "Genital diseases, male", "Wounds and injuries". Algunas referencias fueron incluidas dada su relevancia clínica. De forma similar a experiencias internacionales, el manejo quirúrgico temprano de la fractura de cuerpos cavernosos en este caso permitió desenlaces clínicos adecuados en el paciente. Conclusiones. El diagnóstico de la fractura de pene se basa en hallazgos clínicos; el manejo quirúrgico temprano debe considerarse como la terapia de elección para esta entidad. El tratamiento conservador presenta una mayor tasa de complicaciones versus el manejo quirúrgico temprano. El caso descrito presenta buenos desenlaces post-operatorios a corto plazo.

Genital myiasis associated with genital piercing. Case report

ABSTRACT CONTEXT: Myiasis is caused by larval infestation that usually occurs in exposed wounds. Dermatobia hominis is the most common fly species responsible for this parasitic infection. Genital piercing is an ornamental practice used in certain social circles. At placement, it transverses the skin surface and, as such, may be related to complications. CASE REPORT: We report a case of a 31-year-old man with a history of wound infection secondary to genital piercing who was exposed to an environment with flies, leading to myiasis. Mechanical removal and systemic antiparasitic drugs are possible treatments for myiasis. However, prevention that includes wound cleaning and dressing is the best way to avoid this disease. CONCLUSIONS: Genital piercing can lead to potential complications and myiasis may occur when skin lesions are not properly treated.

Ultrasound evaluation of the penis / Avaliação ultrassonográfica do pênis

Abstract Ultrasound is an excellent method for the study of penis. In this article, using a critical review of the literature and teaching files, we present examples of the major findings in the ultrasound routine, focusing on trauma, priapism, Peyronie's disease, and erectile dysfunction.

Resumo A ultrassonografia é um excelente método para a avaliação peniana.

An unanswered question in pediatric urology: the post pubertal persistence of prepubertal congenital penile curvature correction by tunical plication

ABSTRACT Objective: The aim of this study is to analyze post pubertal results of pre pubertal tunica albuginea plication with non-absorbable sutures in the correction of CPC. Materials and Methods: The files of patients who underwent tunica albuginea plication without incision (dorsal/lateral) were retrospectively reviewed. Patients younger than 13 years of age at the time of operation and older than 14 years of age in November 2015 were included. Patients with a penile curvature of less than 30 degrees & more than 45 degrees and penile/urethral anomalies were excluded. All of the patients underwent surgery followed by circumcision. Results: The mean age of patients at the time of the operation was 9.7 years (range, 6-13 years). The mean degree of ventral penile curvature measured during the operation was 39 degrees while it was 41 degrees in the lateral curvatures. All of the patients were curvature-free at the end of the operation. At the time of the follow-up examination, the mean age was 16.7 years (range, 14-25 years). Six patients had a straight (0-10 degrees) penis during erection and seven patients had recurrent penile curvatures ranging from 30 to 50 degrees. Conclusion: Pre pubertal tunica albuginea plication of congenital penile curvature (30-45 degrees) with non-absorbable sutures performed without incision is a minimal invasive method especially when performed during circumcision. However, recurrence might be observed in half of the patients after puberty.

Púrpura de Schonlein-Henoch con afectación peniana: Caso clínico / Henoch-Schonlein purpura involving the penis: A case report

La púrpura de Schonlein-Henoch es responsable de la mayoría de los casos de vasculitis sistémica en niños. La forma de presentación clásica se caracteriza por púrpura palpable, glomerulonefritis, artralgias y dolor abdominal. Aunque manifestaciones genitourinarias, como la afectación testicular y escrotal, han sido ampliamente descritas, otras, como la afectación peniana, son muy raras. Presentamos el caso de un varón de 6 años que consultó por presentar un exantema purpúrico en el glande, el prepucio y el cuerpo del pene, junto con edema doloroso en dicha región. En los tres días previos, había presentado una historia de fiebre, exantema purpúrico palpable en las nalgas y los miembros inferiores, y artralgia de la muñeca derecha. Fue ingresado con el diagnóstico de púrpura de Schonlein-Henoch con afectación peniana y se inició un tratamiento corticoideo oral (prednisona). A los dos días del inicio del tratamiento, se observó una notable mejoría de los síntomas.

Schonlein-Henoch purpura accounts for the majority of cases of systemic vasculitis in children. Classical presentation is characterized by palpable purpura, glomerulonephritis, arthralgias and abdominal pain. Although genitourinary manifestations, in form of testicular and scrotal involvement, have been widely described, penile involvement remains an extremely rare complication. We report a case of a 6-year-old boy who presented with purpuric rash on the glans, prepuce and penile shaft, with painful edema in the penile region. He also had a 3-days history of fever, palpable purpuric rash on the buttocks and lower extremities along with right wrist pain. He was admitted with the diagnosis of Schonlein-Henoch purpura with penile involvement. After 2 days on oral steroids therapy (prednisone) a marked improvement was observed.

Penile ulcer as a specific clinical manifestation of Waldenstrom's macroglobulinemia

Abstract Waldenstrom’s macroglobulinemia is considered a lymphoma by the World Health Organization. Cutaneous lesions, particularly of a specific type, are rare occurring in 5% of patients. What draws attention in this case is the unusual cutaneous clinical manifestation and its location on the genitals, which has not been described in researched literature, therefore imposing differential diagnosis with other etiologies of genital ulcers.

Penile Fracture: Our Experience in a Tertiary Care Hospital

PURPOSE: Penile fracture is rare, but it is a urological emergency that always requires immediate attention. Moreover, penile fracture has been reported more frequently in recent years. It may have devastating physical, functional, and psychological consequences if not properly managed in time. MATERIALS AND METHODS: The objective of this study was to highlight the causes, clinical presentation, and outcomes of cases of penile fracture. This was a prospective observational study extending from November 2012 to November 2014. Each patient underwent a thorough clinical evaluation and received proper treatment. RESULTS: Twenty patients with penile fracture, aged 19 to 56 years (mean, 28 years) were evaluated in this study. Vaginal intercourse was the most common mechanism of injury. Most of the patients (95%) were diagnosed clinically with a proper history and clinical examination. Nineteen patients were treated surgically. The patients underwent six months of follow-up, and were evaluated with local examinations, questionnaires, and colour Doppler ultrasonography as necessary. CONCLUSIONS: Although penile fracture is an under-reported urological emergency, its incidence is increasing. It is usually diagnosed based on a clinical examination, but ultrasonography can be very helpful in diagnosis. Especially in cases where treatment is delayed, surgery is preferable to conservative management, because it is associated with better outcomes and fewer long-term complications.

Penile enlargement with methacrylate injection: is it safe? / Aumento peniano com injeção de metacrilato: isto é seguro?

Penis size is a great concern for men in many cultures. Despite the great variety of methods for penile augmentation, none has gained unanimous acceptance among experts in the field. However, in this era of minimally invasive procedure, injection therapy for penile augmentation has become more popular. Here we report a case of methacrylate injection in the penis that evolved with penile deformity and sexual dysfunction. This work also reviews the investigation and management of this pathological condition.

A 36-year-old male sought medical care with a complaint of penile deformity and sexual dysfunction after methacrylate injection. The treatment administered was surgical removal. Satisfactory cosmetic and functional results were reached after two months.

There is a need for better structured scientific research to evaluate the outcomes and complication rates from all penile augmentation procedures. .

O tamanho peniano é uma grande preocupação para homens em diversas culturas. Apesar da grande variedade de possíveis métodos para o aumento peniano, nenhum ganhou aceitação unânime por especialistas no assunto. Mas na era dos procedimentos minimamente invasivos, a terapia de injeção para aumento peniano tem se tornado mais popular. Aqui relatamos um caso de injeção de metacrilato no pênis que evoluiu com deformidade peniana e disfunção sexual. Este trabalho também revisa a investigação e gerenciamento desta afecção.

Um homem de 36 anos procurou atendimento médico com queixa de deformidade peniana e disfunção sexual após injeção de metacrilato. Remoção cirúrgica foi realizada como tratamento. Após dois meses, satisfatórios resultados cosmético e funcional foram alcançados.

Trabalhos científicos mais bem estruturados para avaliar as taxas de complicação e resultados de todos os procedimentos para aumento peniano são necessários. .

Prevalence and risk factors for penile lesions/anomalies in a cohort of Brazilian men ≥ 40 years of age

Purpose To report the prevalence and risk factors of penile lesions/anomalies in a Metropolitan Brazilian city. Materials and Methods All participants undergoing prostate cancer screening in the city of Curitiba were systematically examined to identify penile lesions including cutaneous mycosis, sexually transmitted diseases, penile cancer, meatal stenosis, hypospadias, and Peyronie's disease. Outcomes of interest included the prevalence and the relative risk and 95% confidence intervals of the lesions/anomalies according to age, school level, race, personal history of diabetes, arterial hypertension, nonspecific urethritis, and vasectomy. Results Balanoposthitis occurred in 11.8% of all participants, with an increased risk in those with diabetes (RR = 1.73), or past history of nonspecific urethritis (RR = 1.58); tinea of the penis was present in 0.2%; condyloma acuminata in 0.5%; herpes virus infection in 0.4%; urethral discharge in 0.2%; genital vitiligo in 0.7%, with an increased prevalence in non-white men (RR = 4.43), and in subjects with lower school level (RR = 7.24); phimosis in 0.5%, with a nearly 7-fold increased risk in diabetics; lichen sclerosus in 0.3%; stenosis of the external urethral meatus in 0.7%, with a higher prevalence in subjects with lichen sclerosus (RR = 214.9), and in those older than 60 years of age (RR = 3.57); hypospadia in 0.6%; fibrosis suggestive of Peyronie's disease in 0.9%, especially in men older than 60 years (RR = 4.59) and with diabetes (RR = 3.91); and penile cancer in 0.06%. Conclusion We estimated the prevalence and risk factors of commonly seen penile diseases in an adult cohort of Brazilian men. .

Carcinoma epidermoide do pênis: estudo clínico-patológico de 34 casos / Squamous cell carcinoma of the penis: clinicopathologic study of 34 cases

FUNDAMENTOS: No Brasil, a incidência do câncer do pênis é de 8,3 casos/100.000 habitantes, contrastando com 0,7 na Europa e nos Estados Unidos. Em 95 por cento dos casos, trata-se do carcinoma epidermoide. Em geral, é diagnosticado tardiamente. OBJETIVOS: Descrever as características clínico-patológicas do carcinoma epidermoide do pênis, registradas no Hospital entre 1978 e 2004. MÉTODOS: Estudo observacional transversal. Incluíram-se os casos de carcinoma epidermoide do pênis, confirmados histologicamente. Avaliaram-se, pessoalmente, os pacientes que atenderam à convocação para o estudo, enquanto os demais tiveram seus dados pesquisados nos prontuários médicos. RESULTADOS: Registraram-se 34 pacientes com carcinoma epidermoide do pênis: 8 in situ e 26 invasivos, com idade média de 54,7 12,5 anos, respectivamente. A± 22,4 e 64,7 ±, (este trecho ficou truncado e não consegui entendê-lo. Será que o autor poderia revisá-lo?!) A glande foi acometida em 91,1 por cento dos casos e o prepúcio, em 41,1 por cento. Os carcinomas epidermoides in situ exibiam pápulas ou eritema e erosão, geralmente menores do que 2 cm. Os invasivos mostravam úlceras e/ou vegetações, geralmente únicas, e maiores do que 2 cm. Dos CE invasivos, 80,8 por cento eram bem diferenciados; metade encontrava-se no estágio I TNM e o restante, do II ao IV; 16 pacientes tiveram o pênis amputado e 3 faleceram. CONCLUSÕES: O câncer do pênis é raro, acomete adultos de todas as faixas etárias e o tratamento pode ser agressivo. O aspecto clínico inespecífico das lesões iniciais, o insuficiente treinamento médico em lesões dermatológicas e a carência de rotinas de investigação diagnóstica, tratamento e acompanhamento destes casos contribuem para o mau prognóstico desta neoplasia.

BACKGROUND: In Brazil, the incidence of penile cancer is 8.3 cases per 100,000 population, in contrast to 0.7 in Europe and the United States. 95 percent of these cases correspond to squamous cell carcinoma (SCC). It is usually diagnosed late. OBJECTIVES: To describe the clinicopathologic features of squamous cell carcinoma of the penis registered at the Hospital between 1978 and 2004. METHODS: A cross-sectional observational study. We included cases of squamous cell carcinoma of the penis that were histologically confirmed. Those patients who responded to the study call were evaluated in person, while others had their data researched in medical records. RESULTS: 34 patients with squamous cell carcinoma of the penis were registered: 8 in situ and 26 invasive, with a mean age of 54.7 ± 22.4 and 64,7 ± 12.5 years, respectively. Glans cancer was involved in 91.1 percent of the cases and the foreskin in 41.1 percent. SCC in situ exhibited papules or erythema and erosion, usually smaller than 2 cm. Invasive SCC was characterized by ulcers and/or vegetation, usually single and bigger than 2 cm. Of the invasive cases, 80.8 percent were well differentiated; half was in the TNM stage I and the remaining in stages II to IV. 16 patients had their penis amputated, and 3 died. CONCLUSIONS: Cancer of the penis is rare and affects adults of all ages and treatment can be aggressive. The nonspecific clinical appearance of early lesions, insufficient medical training in skin lesions and lack of routine diagnostic investigation, treatment and follow up of these cases contribute to the poor prognosis of this neoplasm.

Estrangulación de la raíz del pene. Presentación de caso / Strangulation of radix penis. A case report

La estrangulación del pene requiere una actuación urgente para evitar lesiones mayores. Se presenta un caso clínico en el cuerpo de guardia de urología con dolor, edema distal y la pérdida de la sensibilidad del pene al cual se le diagnosticó estrangulación de la raíz del pene por un cuerpo extraño grado II, en el Hospital General Docente "Abel Santamaría Cuadrado" de Pinar del Río. Se realizaron diversas maniobras con el instrumental disponible con resultados insatisfactorios, y empleó el instrumental ortopédico para la extracción del cuerpo extraño, por lo que se hizo necesaria la interconsulta con los especialistas de ortopedia en cuanto al instrumental a utilizar, para garantizar un resultado adecuado sin graves daños para el paciente. Se utilizó anestesia local proximal, previa al proceder. Posteriormente, se realiza la extracción del cuerpo extraño de forma satisfactoria. Se realizó una revisión de la literatura donde se recogen diferentes objetos, sin mencionar el objeto que se presentó en el caso, e intentó simplificar las distintas técnicas para su resolución.

The strangulation of the radix penis requires urgent proceedings to avoid major lesions. A clinical case with bad pain, distal edema and loss of penis feeling, with the early diagnosis of strangulation of the radix penis due to a foreign body of degree-II was presented in the Emergency room of Urology at "Abel Santamaria Cuadrado" University Hospital, Pinar del Rio. Several maneuvers with the available instruments were performed without obtaining satisfactory results where also orthopedic instruments were used to remove the foreign body. A secondary referral to orthopedics was required to use the adequate instruments to remove the foreign body, in order to provide good results without severe damages to the patient as well. Local proximal anesthesia was used before proceedings. Subsequently, the removal of the foreign body was satisfactory. A medical literature review was carried, where the object of the case was not mentioned, trying to simplify the different techniques to its resolution.
