Analysis of the incidence of venous thromboembolic disease in urological inpatients during perioperation / 中华泌尿外科杂志

Objective:To investigate the incidence of venous thromboembolic disease (VTE) in urological inpatients during perioperation.Methods:The clinical data of 7 988 inpatients admitted to the Department of Urology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from January to December 2019 were analyzed retrospectively. The cohort included 5 657 males and 2 331 females. The average age of the enrolled patients was (56.3±15.8) years old, and the body mass index was (23.8±3.2) kg/m 2. There were 1 628 malignant tumors patients and 6 360 non-malignant tumors patients in the cohort. Of all the patients, 7 725 cases received surgical treatment. All patients were scored with the Caprini Risk Assessment Model (2005) after admission and 1 655 cases were classified as very low risk, 2 940 cases were low risk, 2 922 cases were medium risk, 345 cases were high risk and 126 cases were very high risk. Patients with Caprini score ≥ 2 and/or clinical symptoms were examined by venous color Doppler ultrasound. CT pulmonary angiography was performed for patients with chest pain, chest tightness, decreased blood oxygen saturation and other symptoms suspected of pulmonary embolism according to clinical judgment to screen the incidence of VTE. Results:Among the 7 988 cases, 180 cases (2.25%, 180/7 988) with VTE were found by preoperative examination, including 1 case (0.01%, 1/7 988) with pulmonary embolism. There were 199 new cases with VTE after operation, and the incidence of new VTE after operation was 2.58% (199/7 725). Among them, pulmonary embolism was found in 7 cases, with a incidence of 0.09% (7/7 725). Only 7.92% (30/379) of the VTE patients had VTE-related symptoms. The operations with higher incidence of VTE were radical cystectomy, nephroureterectomy, radical prostatectomy and radical nephrectomy, with the incidence of 11.61% (13/112), 10.87 (10/92), 8.25% (16/194) and 6.16% (22/357) respectively.Conclusions:The incidence of VTE in hospitalized patients with urinary surgery in this study is much higher than previously reported. Most of the patients with VTE are asymptomatic. The operations with high incidence of VTE after operation are radical cystectomy, nephroureterectomy, radical prostatectomy and radical nephrectomy. Therefore, it is necessary to carry out VTE screening for hospitalized patients in urology department, which is helpful to realize early intervention of VTE and reduce the risk of VTE progression and pulmonary embolism.

Melanoma metastásico a vejiga / Metastatic melanoma to the bladder / Melanoma metastático na bexiga

Introducción. El compromiso tumoral metastásico del melanoma al tracto genitourinario es frecuente, pero, la metástasis a vejiga es rara, constituye menos del 2% de los casos. Sin embargo, en autopsias realizadas a pacientes con melanoma se ha encontrado metástasis en la vejiga en entre un 18% y un 37% de los casos, lo que la convierte en la segunda en incidencia posterior al adenocarcinoma gástrico. La media de supervivencia suele ser entre 6 - 7.5 meses. El objetivo de este trabajo es presentar el caso de un melanoma metastásico a vejiga, entidad poco frecuente y poco diagnosticada por ser la mayoría de las veces asintomática. Presentación del caso. Paciente femenina de 62 años, con antecedente de melanoma al nivel del primer artejo del pie, con manejo quirúrgico y farmacológico. Consultó por hematuria. La cistoscopia evidenció una lesión única sólida, eritematosa, con necrosis y fácil sangrado y se indicó realizar resección transuretral (RTU). La patología demostró compromiso por melanoma ulcerado metastásico. Se inició manejo de segunda línea (Pembrolizumab) y presentó progresión a miembros superiores y recaída a nivel vesical. La paciente falleció un año después. Discusión. Las metástasis de melanoma al tracto genitourinario son frecuentes, pero las metástasis vesicales aisladas son raras. El tratamiento suele ser RTU de la lesión, cistectomía, quimioterapia y radioterapia. La RTU es curativa para las lesiones restringidas al epitelio, aunque la cistectomía radical suele ser la terapia de elección ante un paciente con un tumor localizado. El Pembrolizumab ha demostrado aumentar la supervivencia. El pronóstico depende del tamaño y profundidad de la invasión. Conclusiones. El compromiso vesical metastásico es poco frecuente y diagnosticado, puede estar presente en pacientes con melanoma, síntomas irritativos urinarios no específicos y hematuria. Suele ser de mal pronóstico, y requiere de manejo quirúrgico asociado a manejo sistémico.

Introduction. Metastatic tumor compromise of melanoma to the genitourinary tract is frequent, but metastasis to the bladder is rare, representing less than 2% of cases. However, autopsies performed on patients with melanoma have found metastases in the bladder in 18-37% of cases, making it the second incidence after gastric adenocarcinoma. The median survival is usually 6 to 7.5 months. The objective of this work is to present the case of a metastatic melanoma to the bladder, a rare and underdiagnosed condition because most of the time it is asymptomatic. Case Presentation. 62-year-old female patient, with a history of melanoma at the level of the first toe, with surgical and pharmacological management. The reason for consultation was hematuria. Cystoscopy revealed a single solid, erythematous lesion with necrosis and easy bleeding, and a transurethral resection (TUR) was indicated. The pathology found compromise for metastatic ulcerated melanoma. Second-line treatment (Pembrolizumab) was started and presented progression to the upper limbs and relapse at the bladder level. The patient died a year later. Discussion. Melanoma metastases to the genitourinary tract are common, but isolated bladder metastases are rare. Treatment is usually TUR of the lesion, cystectomy, chemotherapy, and radiation therapy. TUR is curative for lesions restricted to the epithelium, although radical cystectomy is usually the therapy of choice in patients with a localized tumor. Pembrolizumab has been shown to increase survival. The prognosis depends on the size and depth of the invasion. Conclusions. Metastatic bladder compromise is rare and underdiagnosed, it may be present in patients with melanoma, non-specific urinary irritative symptoms, and hematuria. It tends to have a poor prognosis, and requires surgical management associated with systemic management.

Introdução. O comprometimento do tumor metastático do melanoma no trato geniturinário é comum, mas a metástase na bexiga é rara, constituindo menos de 2% dos casos. Entretanto, em autópsias realizadas em pacientes com melanoma, foi encontrada metástase na bexiga entre 18% e 37% dos casos, o que a torna a segunda em incidência após o adenocarcinoma gástrico. A média de sobrevivência é geralmente entre 6 - 7,5 meses. O objetivo deste trabalho é apresentar o caso de um melanoma metastático na bexiga, uma entidade pouco frequente e subdiagnosticada, pois na maioria das vezes é assintomática. Apresentação do caso. Paciente do sexo feminino, 62 anos, com antecedentes de melanoma no nível do hálux, com manejo cirúrgico e farmacológico. Ela consultou por hematúria. A cistoscopia revelou uma única lesão sólida, eritematosa com necrose e sangramento fácil, e foi indicada uma ressecção transuretral (RTU). A patologia mostrou comprometimento de melanoma ulceroso metastático. O tratamento de segunda linha (Pembrolizumab) foi iniciado e a patologia avançou para os membros superiores e uma recaída no nível da bexiga. A paciente morreu um ano depois. Discussão. As metástases de melanoma para o trato geniturinário são frequentes, mas as metástases vesicais isoladas são raras. O tratamento é geralmente RTU da lesão, cistectomia, quimioterapia e radioterapia. A RTU é curativa para lesões restritas ao epitélio, embora a cistectomia radical seja geralmente a terapia de escolha para um paciente com um tumor localizado. O Pembrolizumab demonstrou aumentar a sobrevivência. O prognóstico depende do tamanho e da profundidade da invasão. Conclusões. O comprometimento vesical metastático é raro e subdiagnosticado, pode estar presente em pacientes com melanoma, sintomas irritantes urinários não específicos e hematúria. Geralmente tem um prognóstico negativo e requer manejo cirúrgico em associação com manejo sistêmico.

Urological Cancer Treatment by a Multidisciplinary Teamthroughout the Covid-19 Pandemic: What Have We Learned? / Tratamiento del cáncer urológico por un equipo multidisciplinario durante la pandemia de Covid-19: ¿Qué hemos aprendido?

Introduction It is known that cancer care is best approached by a multidisciplinary team (MDT). This became specifically true in the Covid-19 pandemic in which choices for urological cancer treatment are influenced by many factors. In some cases, delayed treatment may have consequences regarding the patient's oncological outcomes. The aim of the present article is to report our experience throughout the Covid-19 pandemic treating patients with urological neoplasms at a high-volume center. Methods We used a convenience sampling method. Cases were evaluated and discussed on an individual basis at the MDT meetings, and, after a consensus regarding delaying or scheduling treatment, patients were scheduled according to the risk of postponing the procedures. The Medically Necessary, Time-Sensitive (MeNTS) scoring system was measured in each patient; all patients answered the Centers for Disease Control and Prevention (CDC) Covid-19 self-screening questionnaire prior to surgery. The Covid-19-free survival rate was estimated. Results A total of 194 patients were assessed by themultidisciplinary team and finally treated, with median follow-up of 4 (interquartile range [IQR]: 2.75 to 6) months. Only two patients had Covid-19 confirmed by real-time polymerase chain reaction (RT-PCR). In total, 54 patients underwent oncological surgery, 129 were treated with radiotherapy, and 11 were treated with intravenous chemotherapy. Themedian age was 66 years (IQR: 59 to 94 years), and the median MeNTS score in the surgically-treated cohort was 35 points (IQR: 31 to 47 points). Conclusions The evaluation and treatment of urological cancer should be conducted by an MDT; this is of utmost importance, especially during the Covid-19 pandemic. The data collected in our institution showed that most patients could be safely treated by taking all necessary precautions and discussing each case individually in the MDT meetings and performing a close follow-up.

Introduccion La atención del cáncer se aborda mejor con un equipo multidisciplinario (EMD), aspecto que se tornó más importante en la pandemia por Covid-19, en que las opciones para tratar el cáncer urológico están influenciadas por muchos factores. En algunos casos, el tratamiento retrasado puede tener consecuencias en los resultados oncológicos del paciente. El objetivo de este estudio es describir nuestra experiencia en un centro de referencia y de alto volumen para el tratamiento de neoplasias urológicas durante la pandemia por Covid-19. Métodos Realizamos un muestreo por conveniencia. Posteriormente, los casos fueron evaluados y discutidos de forma individual en las reuniones del EMD. Posterior a la obtención de un consenso sobre el tratamiento del paciente, los pacientes fueron programados según el riesgo individual de posponer el manejo. Se midió la puntuación de cada paciente en el sistema Medically Necessary Time-Sensitive (MeNTS, "Médicamente necesario, sensibles al tiempo"). Todos los pacientes respondieron el cuestionario de autoevaluación del Centers for Disease Control and Prevention (CDC) COVID-19 antes de la cirugía. Se estimó la tasa de supervivencia libre de Covid-19. Resultados Un total de 194 pacientes fueron evaluados por el EMD y finalmente tratados, con una mediana de seguimiento de 4 (rango intercuartil [RIC]: 2,75 a 6) meses. Solo dos tenían Covid-19 confirmado por reacción en cadena de la polimerasa en tiempo real (RCP-TR). Un total de 54 pacientes fueron sometidos a cirugía oncológica, 129 fueron tratados con radioterapia, y 11 fueron tratados con quimioterapia intravenosa. La mediana de edad fue de 66 años (RIC: 59 a 94 años), la puntuación mediana en el MeNTS de la cohorte tratada quirúrgicamente fue de 35 puntos (RIC: 31 a 47 puntos). Conclusiones La evaluación y el tratamiento del cáncer urológico debe ser realizado por un EMD durante la pandemia de Covid-19. Los datos recopilados en nuestra institución mostraron que la mayoría de los pacientes podrían ser tratados de manera segura, discutiendo cada caso individualmente y haciendo un seguimiento cercano.

Lipogranuloma Esclerosante Escrotal Primario. Reporte de caso y revisión de la literatura / Primary Scrotal Sclerosing Lipogranuloma. Case report and literature review

RESUMEN El lipogranuloma esclerosante es una condición extraña y benigna que puede afectar cualquier órgano, especialmente los genitales externos masculinos. Se suele presentar como masas subcutáneas en escroto, periné y pene. Aunque la mayoría de los casos son secundarios a aplicación de cuerpos extraños como parafina, vaselina o silicona con propósitos estéticos para aumentar el tamaño del pene, también puede deberse a degeneración lipídica endógena, secundaria a trauma, infecciones o reacciones alérgicas. No existe consenso en cuanto a su manejo ni datos sobre su prevalencia al ser una entidad poco reportada; se ha descrito el manejo con ciclos cortos de corticoides sistémicos, y cirugía en los casos recidivantes. El objetivo de este trabajo es reportar el caso de un paciente que acudió con induración y eritema en pene y escroto, quien negaba la aplicación de sustancias exógenas y que fue llevado a biopsia de la lesión, con diagnóstico de lipogranuloma esclerosante. MÉD.UIS.2021;34(2): 97-102.

ABSTRACT Sclerosing lipogranuloma is a noncommon and benign disease that could affect any system in the body, especially the male external genitalia. It is usually presented as a subcutaneous mass in scrotum, perineum and penis. Although, most cases are secondary to the injection of foreign bodies such as paraffin, petrolatum or silicone for cosmetic purposes to increase penis size, it could also be due to endogenous lipid degeneration, secondary to trauma, infections or allergic reactions. There is no unanimity regarding its management or data on its prevalence as it is a poorly reported entity. Management with short cycles of systemic corticosteroids and surgery in relapsing cases have been described. The purpose of this article is to present a case of a patient with induration and erythema in penis and scrotum, who denied the application of exogenous substances and has a reported biopsy of the lesion with diagnosis of sclerosing lipogranuloma.
