RESUMO
Introducción: El cáncer vesical es una enfermedad que afecta, generalmente, a pacientes masculinos de la tercera edad. Este tumor tiene dos formas principales de manifestarse: como tumor superficial y de bajo grado, o como neoplasia invasora de alto grado. La mayoría de los pacientes afectados con esta enfermedad presentan como factor de riesgo, el consumo de tabaco. Objetivo: Contribuir al conocimiento de la comunidad científica en lo relativo a los factores de riesgo y al síntoma principal asociados al cáncer vesical en pacientes adultos de la tercera edad. Métodos: Se realizó una revisión sistemática sobre el tema en las bases de datos: SciELO, EBSCO, Scopus, PubMed, y en revistas de Urología. Los artículos fueron publicados en idioma español o inglés. Se realizó un análisis del contenido para lograr la actualización teórica del tema. Conclusiones: El cáncer vesical es una enfermedad multifocal que provoca la aparición de varias neoformaciones dentro del epitelio transicional, en toda su extensión. La presencia de hematuria asintomática en los pacientes adultos fue la causa más común de consulta con el urólogo. Dentro de los factores de riesgo, el principal fue el consumo de tabaco.
Introduction: bladder cancer is a disease that generally affects elderly male patients. This tumour has two main forms of manifestation: as a low-grade superficial tumor or as a high-grade invasive neoplasm. Most of the patients affected with this disease have tobacco consumption as a risk factor. Objective: to contribute to the knowledge of the scientific community in relation to the risk factors associated with bladder cancer in elderly patients. Methods: a systematic review on the subject was carried out in SciELO, EBSCO, Scopus and PubMed databases as well as in Urology journals. Articles published in Spanish or English languages were taken into account. A content analysis was conducted to achieve a theoretical update on this topic. Conclusions: bladder cancer is a multifocal disease that causes the appearance of several neoformations within the transitional epithelium and throughout its entire length. The presence of asymptomatic hematuria in adult patients was the most common reason for consultation with the urologist. The main risk factor was tobacco consumption.

Fundamento: El cáncer primario de uretra se define como el tumor cuya primera lesión se localiza en la uretra; es infrecuente, el mismo representa menos del 1 % de los tumores malignos y el 5 % de los tumores malignos del sistema urinario. La extensión de este proceso a la glándula prostática genera sintomatología urinaria obstructiva e irritativa y cuadros agudos como la hematuria macroscópica. Objetivo: Presentar el caso de un paciente con cáncer primario de uretra en su variedad urotelial con hematuria macroscópica como forma clínica de presentación. Presentación del caso: Caso clínico de un paciente masculino de 75 años de edad, con hematuria macroscópica como forma clínica de presentación de cáncer primario de uretra en su variedad urotelial, el cual se diagnosticó anatomopatológicamente durante el estudio de la hematuria. Conclusiones: El caso que se presenta permite alertar a la comunidad científica que en pacientes que presentan hematuria macroscópica, sin manifestaciones urológicas obstructivas ni irritativas, también debe tenerse en cuenta el diagnóstico de cáncer uretral primario, aunque sea un signo infrecuente como forma clínica de presentación de esa enfermedad.
Background: Primary urethral cancer is defined as a tumor whose first lesion is located in the urethra; is very uncommon, represents less than 1% of malignant tumors and 5% of malignant tumors of the urinary system. The extension of this process to the prostate gland creates obstructive and irritative urinary symptoms and acute conditions such as macroscopic hematuria. Objective: To present the case of a patient with primary urethral carcinoma in its urothelial variety with macroscopic hematuria as clinical presentation. Case presentation: Clinical case of a 75-year-old male patient, with macroscopic hematuria as a clinical presentation of primary cancer of the urethra in its urothelial variety, diagnosed anatomopathologically during the hematuria study. Conclusions: The case presented alerts the scientific community that the diagnosis of primary urethral cancer should be considered in patients with macroscopic hematuria in the absence of obstructive or irritative urologic manifestations, although it is a rare sign as clinical presentation of this disease.

La hematuria en pediatría responde habitualmente a etiologías benignas. Una causa poco frecuente es el síndrome de cascanueces, que se define como la compresión de la vena renal izquierda entre la aorta y la arteria mesentérica superior, que deriva en una presión elevada en la vena renal izquierda con el desarrollo de venas colaterales y dilataciones varicosas. La prevalencia de este síndrome se desconoce. Cuando es sintomático ocasiona hematuria, proteinuria y dolor pélvico crónico. En la pubertad, el crecimiento rápido y el desarrollo de los cuerpos vertebrales pueden producir un estrechamiento del ángulo entre la aorta y la arteria mesentérica superior. Se describe el caso de una adolescente con diagnóstico de carcinoma mucoepitelial metastásico óseo múltiple que presenta hematuria anemizante. Se arribó al diagnóstico de síndrome de cascanueces y se discutieron las opciones de tratamiento. Finalmente, con el uso de realce del calzado para corrección de la escoliosis, se atenuó significativamente la hematuria. (AU)
In pediatrics, hematuria usually responds to benign etiologies. A rare cause is nutcracker syndrome, defined as compression of the left renal vein between the aorta and the superior mesenteric artery, resulting in elevated pressure in the left renal vein with the development of collateral veins and varicose dilatation. The prevalence of this syndrome is unknown. When symptomatic, it causes hematuria, proteinuria, and chronic pelvic pain. At puberty, the rapid growth and development of the vertebral bodies can produce a narrowing of the angle between the aorta and the superior mesenteric artery.We describe the case of a teenage girl diagnosed with multiple metastatic mucoepithelial carcinoma of bone who presented anemia-producing hematuria. The diagnosis of nutcracker syndrome was arrived at with consideration of the therapeutic options. Finally, with shoe enhancement for scoliosis correction, hematuria was significantly lessened. (AU)

OBJECTIVES@#To investigate the clinical characteristics, pathology, and prognosis of children with diffuse endocapillary proliferative Henoch-Schönlein purpura nephritis (DEP-HSPN).@*METHODS@#A retrospective analysis was performed on the clinical, pathological, and prognosis data of 44 children with DEP-HSPN and 765 children without DEP-HSPN. The children with DEP-HSPN were diagnosed by renal biopsy in Jiangxi Provincial Children's Hospital from January 2006 to December 2021.@*RESULTS@#Among the 809 children with purpura nephritis, 44 (5.4%) had DEP-HSPN, with a mean age of (8±3) years, and there were 29 boys (65.9%) and 15 girls (34.1%). Compared with the non-DEP-HSPN group, the DEP-HSPN group had a significantly shorter time from onset to renal biopsy and a significantly higher proportion of children with respiratory infection or gross hematuria, and most children had nephrotic syndrome. The DEP-HSPN group had significantly higher levels of 24-hour urinary protein, urinary protein grading, microscopic hematuria grading, serum creatinine, and blood urea nitrogen and significantly lower levels of serum albumin and complement C3 (P<0.05). The DEP-HSPN group had a higher pathological grading, with predominant deposition of IgA in the mesangial area and capillary loops, and higher activity scores in the modified semi-quantitative scoring system (P<0.05). The Kaplan-Meier survival analysis showed that there was no significant difference in the renal complete remission rate between the two groups (P>0.05).@*CONCLUSIONS@#Children with DEP-HSPN have a rapid onset, severe clinical manifestations and pathological grading, and high activity scores in the modified semi-quantitative scoring system. However, most of the children with DEP-HSPN have a good prognosis, with a comparable renal complete remission rate to the children without DEP-HSPN.

OBJECTIVES@#To investigate the genotypes of the pathogenic gene COL4A5 and the characteristics of clinical phenotypes in children with Alport syndrome (AS).@*METHODS@#A retrospective analysis was performed for the genetic testing results and clinical data of 19 AS children with COL4A5 gene mutations.@*RESULTS@#Among the 19 children with AS caused by COL4A5 gene mutations, 1 (5%) carried a new mutation of the COL4A5 gene, i.e., c.3372A>G(p.P1124=) and presented with AS coexisting with IgA vasculitis nephritis; 3 children (16%) had large fragment deletion of the COL4A5 gene, among whom 2 children (case 7 had a new mutation site of loss51-53) had gross hematuria and albuminuria at the onset, and 1 child (case 13 had a new mutation site of loss3-53) only had microscopic hematuria, while the other 15 children (79%) had common clinical phenotypes of AS, among whom 7 carried new mutations of the COL4A5 gene. Among all 19 children, 3 children (16%) who carried COL4A5 gene mutations also had COL4A4 gene mutations, and 1 child (5%) had COL4A3 gene mutations. Among these children with double gene mutations, 2 had gross hematuria and proteinuria at the onset.@*CONCLUSIONS@#This study expands the genotype and phenotype spectrums of the pathogenic gene COL4A5 for AS. Children with large fragment deletion of the COL4A5 gene or double gene mutations of COL4A5 with COL4A3 or COL4A4 tend to have more serious clinical manifestations.

OBJECTIVE@#To analyze the clinical phenotype and genetic characteristics of a patient with Alport syndrome.@*METHODS@#A patient with Alport syndrome who had visited the First Affiliated Hospital of Zhengzhou University in November 2020 was selected as the study subject. Clinical data of the patient were collected. High-throughput sequencing was carried out to detect potential variant of the COL4A3, COL4A4 and COL4A5 genes, and Sanger sequencing was carried out for verification of candidate variants in the family.@*RESULTS@#The main clinical manifestations of the patient included hematuria, proteinuria, and impaired hearing. Audiometric testing suggested symmetrical cochlear sensory neural hearing loss on both sides. Renal biopsy revealed mild mesangial proliferative glomerulonephritis. Genetic testing revealed that the patient has harbored compound heterozygous variants of the COL4A4 gene, namely c.940G>A (p.Gly314Ser) and c.3773G>A (p.Gly1258Asp), which were respectively inherited from her father and mother. Neither variant has been reported before, and were predicted to be pathogenic based on the guidelines from the American College of Medical Genetics and Genomics.@*CONCLUSION@#The c.940G>A (p.Gly314Ser) and c.3773G>A (p.Gly1258Asp) compound heterozygous variants of the COL4A4 gene probably underlay the Alport syndrome in this patient. Above finding has enriched the mutational spectrum of the COL4A4 gene.

OBJECTIVE@#To compare the safety and effectiveness of active migration technique and in situ lithotripsy technique in the treatment of 1-2 cm upper ureteral calculi by retrograde flexible ureteroscopy.@*METHODS@#A total of 90 patients with 1-2 cm upper ureteral calculi treated in the urology department of Beijing Friendship Hospital from August 2018 to August 2020 were selected as the subjects. The patients were divided into two groups using random number table: 45 patients in group A were treated with in situ lithotripsy and 45 patients in group B were treated with active migration technique. The active migration technique was to reposition the stones in the renal calyces convenient for lithotripsy with the help of body position change, water flow scouring, laser impact or basket displacement, and then conduct laser lithotripsy and stone extraction. The data of the patients before and after operation were collected and statistically analyzed.@*RESULTS@#The age of the patients in group A was (51.6±14.1) years, including 34 males and 11 females. The stone diameter was (1.48±0.24) cm, and the stone density was (897.8±175.9) Hu. The stones were located on the left in 26 cases and on the right in 19 cases. There were 8 cases with no hydronephrosis, 20 cases with grade Ⅰ hydronephrosis, 11 cases with grade Ⅱ hydronephrosis, and 6 cases with grade Ⅲ hydronephrosis. The age of the patients in group B was (51.8±13.7) years, including 30 males and 15 females. The stone diameter was (1.52±0.22) cm, and the stone density was (964.6±214.2) Hu. The stones were located on the left in 22 cases and on the right in 23 cases. There were 10 cases with no hydronephrosis, 23 cases with grade Ⅰ hydronephrosis, 8 cases with grade Ⅱ hydronephrosis, and 4 cases with grade Ⅲ hydronephrosis. There was no significant diffe-rence in general parameters and stone indexes between the two groups. The operation time of group A was (67.1±16.9) min and the lithotripsy time was (38.0±13.2) min. The operation time of group B was (72.2±14.8) min and the lithotripsy time was (40.6±12.6) min. There was no significant difference between the two groups. Four weeks after operation, the stone-free rate in group A was 86.7%, and in group B was 97.8%. There was no significant difference between the two groups. In terms of complications, 25 cases of hematuria, 16 cases of pain, 10 cases of bladder spasm and 4 cases of mild fever occurred in group A. There were 22 cases of hematuria, 13 cases of pain, 12 cases of bladder spasm and 2 cases of mild fever in group B. There was no significant difference between the two groups.@*CONCLUSION@#Active migration technique is safe and effective in the treatment of 1-2 cm upper ureteral calculi.

Introduction: les urgences en urologie sont des situations urologiques critiques qui nécessitent une intervention rapide par un professionnel de santé qualifié en urologie. Cette étude a été menée dans le but de ressortir le profil des urgences urologiques reçues dans deux hôpitaux universitaires de la ville de Douala en appréciant leurs prises en charge en urgence. Méthodes: il s´agit d´une étude rétrospective portant sur les urgences urologiques dans deux hôpitaux de références de la ville de Douala que sont les hôpitaux Laquintinie et Général de Douala. Les dossiers ont été colligés durant une période de 5 ans (1er janvier 2016 au 31 décembre 2020). Nous avons inclus toutes les consultations effectuées en urgence et reçues par le service des urgences ainsi que toutes les données cliniques et thérapeutiques venant du registre de garde durant la période d´étude. Nous avons exclu de notre étude toutes les urgences (consultations reçues pendant la période d´étude, non relevées dans le registre des urgences) Résultats: nous avons étudié 364 patients, l´âge moyen des patients était de 43 ± 8,34 ans. Quatre vingt-douze virgule cinquante huit pourcent (92,58%) (n=337) des patients étaient des hommes. Les principales urgences urologiques reçues étaient la rétention d´urine vésicale (45,05%, n=164), la colique néphrétique (15,33%, n=56) et l´hématurie (13,18%, n=48). Les principales étiologies des rétentions d´urine vésicale étaient les tumeurs prostatiques, la colique néphrétique était principalement d´origine lithiasique (96,45%, n=159) et l´hématurie était d´origine tumorale chez 68,75%(n=33) des patients. Sur le plan thérapeutique, les gestes effectués en urgence étaient le sondage vésical (39,01%, n=142), le traitement médical était associé à une surveillance (27,47%, n=100) et la cystostomie sus pubienne (10,71%, n=39). Conclusion: les rétentions aigues d´urines vésicales sur tumeurs prostatiques constituent l´urgence urologique la plus fréquente dans les hôpitaux universitaires de la ville de Douala. Cela implique une prise en charge précoce et optimale des tumeurs prostatiques.

Introduction. Renal involvement among pediatric patients with coronavirus disease 2019 (COVID-19) ranges between 1.2% and 44%. Given the limited information available locally, the primary objective of this study was to estimate the prevalence of renal involvement in our setting. Population and methods. Cross-sectional study conducted in 13 Argentine sites between March and December 2020. Patients aged 1 month to 18 years hospitalized due to COVID-19 and with at least one measurement of serum creatinine and/or a urinalysis were included. Those with a known kidney disease were excluded. Renal involvement was defined as the presence of acute kidney injury (AKI), proteinuria, hematuria, leukocyturia and/or arterial hypertension (HTN). Results. Among 528 eligible medical records, 423 patients were included (55.0% were males; median age: 5.3 years). The clinical presentation was asymptomatic in 31%; mild, in 39.7%; moderate, in 23.9%; severe, in 1.2%; critical, in 0.7%; and 3.5% had multisystem inflammatory syndrome in children (MIS-C). Two patients (0.47%) died. The prevalence of renal involvement was 10.8% (95% confidence interval: 8.214.2); it was described as leukocyturia (16.9%), proteinuria (16.0%), hematuria (13.2%), HTN (3.7%), and AKI (2.3%). No patient required dialysis. Renal involvement was associated with severe forms of disease (p < 0.0001). Conclusion. The prevalence of renal involvement among pediatric patients hospitalized due to COVID-19 in 13 Argentine sites was 10.8%; severe forms of disease prevailed.

Los carcinomas uroteliales son el 4to tumor más común. Pueden ubicarse en el tracto urinario inferior (vejiga y uretra) o en el tracto urinario superior (cavidades renales, pelvis renal y uréter). Presentamos una serie de 3 casos, con cuadro de hematuria macroscópica, documentando tumores uroteliales, realizándose en estos casos un abordaje lumboscópico de riñón y una resección endoscópica del rodete vesical. Se realiza nefroureterectomía lumboscópica con resección de rodete vesical endoscópica transuretral. Los 3 pacientes fueron egresados al segundo día posquirúrgico sin complicaciones y en los tres casos el rodete vesical sin evidencia de actividad tumoral, y actualmente en vigilancia con excelente resultados oncológicos. La nefroureterectomía lumboscópica con resección endoscópica del rodete vesical es una técnica reproducible en manos experimentadas, con iguales resultados oncológicos que el abordaje abierto.
Urothelial carcinomas are the 4th most common tumor. They can be located in the lower urinary tract (bladder and urethra) or in the upper urinary tract (renal cavities, renal pelvis, and ureter). We present a series of 3 cases, with a picture of macroscopic hematuria, documenting urothelial tumors, performing in these cases a lumboscopic approach to the kidney and an endoscopic resection of the bladder rim. Lumboscopic nephroureterectomy was performed with transurethral endoscopic bladder rump resection. The 3 patients were discharged on the second postoperative day without complications and in the three cases the bladder rim without evidence of tumor activity, and currently under surveillance with excellent oncological results. Lumboscopic nephroureterectomy with endoscopic resection of the bladder rim is a reproducible technique in experienced hands, with the same oncological results as the open approach.

Resumen Introducción: La embolización de arteria renal (EAR) es un procedimiento percutáneo que ocluye la arteria renal, con la consecuente isquemia del territorio vascular. Sus indicaciones más comunes son la hematuria y el manejo paliativo en cáncer renal metastásico. A pesar del desarrollo técnico y de la experiencia progresiva, los estudios incluyen un número reducido de pacientes y en nuestro país se revisan casos aislados. Objetivo: Describir la experiencia en el Servicio de Salud Valparaíso San Antonio y revisar la literatura existente. Materiales y Método: Realizamos un estudio descriptivo de los pacientes sometidos a EAR por anemia severa secundaria a hematuria, durante los años 2012 a 2020. Posteriormente, realizamos una revisión de la literatura en PubMed, hasta abril de 2020. Resultados: Incluimos 9 pacientes, 6 (66,7%) hombres y 3 (33,3%) mujeres. La mediana de edad fue de 69 años (RIC = 18). La principal causa de la hematuria fue cáncer renal avanzado (7 pacientes). No hubo complicaciones, y se logró éxito clínico en todos los pacientes. Nuestra búsqueda de literatura arrojó 571 referencias y 24 cumplieron con nuestros criterios de elegibilidad. La edad de los pacientes y las causas subyacentes de hematuria fueron variadas. La menor tasa de éxito clínico fue de 65%, sin embargo, 15 estudios (62,5%) reportaron un éxito igual o mayor al 90%. Seis estudios reportaron más de un 10% de pacientes con alguna complicación. Conclusión: Nuestros resultados y la evidencia revisada muestran que la EAR parece ser segura y eficaz en el manejo de anemia severa secundaria a hematuria.
Introduction: Renal artery embolization (RAE) is a percutaneous procedure that occludes the renal artery, with consequent ischemia of the vascular territory. The most common indications include hematuria and palliation for metastatic renal cancer. Despite technical development and progressive experience, studies include a small number of patients and few cases have been published in our country. Aim: To share our experience at Valparaíso-San Antonio Health Service and to review the existing literature. Materials and Method: We performed a retrospective descriptive review of medical records of patients with severe anemia due to hematuria managed with RAE, between 2012 and 2020. Subsequently, we conducted a literature search in PubMed, from inception until April 2020. Results: We included 9 patients. There were 6 (66.7%) males and 3 (33.3%) females with a median age of 69 years (IQR = 18). Main cause of hematuria was advanced kidney cancer (7 patients). There were no complications and clinical success was achieved in all patients. Our literature search yielded 571 references, 24 met our eligibility criteria. The age of patients and the underlying causes of hematuria were varied. The lowest clinical success rate was 65%, however, 15 studies (62.5%) reported a success equal to or greater than 90%. Six studies reported more than 10% of patients with complications. Conclusión: Our results and the studies reviewed show that RAE appears to be safe and effective in the management of patients with severe anemia due to hematuria.

Objective@#One of the common clinical problems warranting urologic evaluation is asymptomatic microscopic hematuria (AMH). According to some studies, it has prevalence as high as 38% with a possibility of urologic disease or malignancy around 23%. The presence of AMH would be quite a dilemma to a urologist in terms of how aggressive urologic evaluation and follow up is recommended. The present study was to determine the incidence of significant urologic diseases among Filipino patients with AMH on initial evaluation and on follow-up. This study would also determine if there would be a significant difference in terms of incidence of urologic disease among patients less than 35 years old and more than 35 years old with AMH.@*Methods@#A total number of 95 patients (38 male, 57 female) were included in this study. All patients presented with AMH. They were grouped in terms of age, gender, and duration of follow-up. All patients underwent cystoscopy and a diagnostic imaging (ultrasound, CT urogram, or CT stonogram) on initial evaluation. Patients then were followed up. They were divided into two groups, those less than 2 years of follow-up and those more than 2 years of follow-up. Excluded from the study are those patients with gross hematuria, on indwelling catheter, with urinary tract infection, with previous malignancy, history of pelvic irradiation, and those who did not undergo cystoscopy, or any urologic imaging. @*Results@#Out of 95 patients with AMH who underwent urologic evaluation, the incidence of urologic disease was noted to be 12% (11 out of 95). There was no malignancy related cause of AMH discovered. Age and gender failed to show any significant difference in terms of developing urologic disease. Among patients with negative findings on initial urologic evaluation, no urologic disease was noted even on follow-up. Among those with positive findings on initial evaluation, no new urologic disease was discovered on follow-up.@*Conclusion@#AMH has a low incidence of urologic disease or any GUT malignancy. Age and gender alone are not sufficient risk factors warranting an invasive endoscopic procedure. They are recommended only to those patients with high risk of urologic disease and can be avoided in majority of the population. We would recommend a kidney, urinary bladder, and prostate (KUBP) ultrasound as the initial imaging of choice since the only findings noted on evaluation through imaging were just two cases of nephrolithiasis, one via CT stonogram and the other through a CT urogram, which can also be diagnosed with a regular KUBP ultrasound. This would be more cost-effective as well as beneficial in terms of the patient’s risk regarding radiation and contrast-related effects. Clinicians may decrease unnecessary repeated urologic evaluation and follow-ups on patients with AMH, as the results of the study failed to show any significant difference in developing urologic disease for patients with persistent AMH on initial assessment and even on follow-up.

It is reported the occurrence of enzootic hematuria (EH) in buffaloes in Brazil after performing an epidemiological survey and clinicopathological analises. To date, EH caused by ingestion of Pteridium esculentum subsp. arachnoideum, a radiomimetic plant popularly known as "bracken fern", has not been described in this species in Brazil. Bovine EH is responsible for high economic losses in Brazil's Southeast Region not only because of the deaths it causes, but also owing to its negative effect on productivity. In São José do Barreiro County, São Paulo, some farmers in areas with a high incidence of bovine EH have been replacing cattle with buffaloes, based on the premise that the latter would be more resistant to poisoning by ingestion of Pteridium spp. However, even though initial observations indicated that buffaloes are indeed less sensitive than cattle to the toxic principle of Pteridium spp., cases of hematuria in this species have been reported. According to preliminary date, EH only occurs in buffaloes over six years of age. Macroscopic examination revealed a thickened urinary vesicle mucosa, along with multiple foci of ulcerated, exophytic, verrucous, and pedunculated lesions. In one of the buffaloes studied, the bladder wall was ruptured and exhibited marked secondary inflammation. Histologically, neoplastic and non-neoplastic changes similar to those described in cattle poisoned by Pteridium spp. were observed. The neoplasms found included papilloma, carcinoma in situ, urothelial carcinoma (low and high grade), inverted, microcystic, and trabecular variants, urothelial carcinoma with divergent differentiation (squamous and glandular), squamous cell carcinoma, lymphangioma, hemangioma, and hemangiosarcoma. There was also coexistence of epithelial and mesenchymal neoplasms. Bovine papillomavirus particles were not detected by polymerase chain reaction in the bladder samples analyzed.
Descreve-se, através de levantamento epidemiológico e avaliação clínico-patológica, a ocorrência de hematúria enzoótica (HE) em búfalos no Brasil. Essa condição, causada pela ingestão da planta radiomimética Pteridium esculentum subsp. arachnoideum, conhecida popularmente como "samambaia" ou "samambaia do campo", até então não havia sido descrita nessa espécie no Brasil. Na Região Sudeste, a HE bovina é responsável por elevadas perdas econômicas, devidas não apenas aos óbitos, mas também em função da queda de produtividade. No município de São José do Barreiro/SP, alguns produtores de áreas com alta incidência de HE bovina, vêm substituindo os bovinos por búfalos, com base na premissa de que estes seriam mais resistentes à intoxicação. Embora, de acordo com observações iniciais, os búfalos realmente sejam menos sensíveis que os bovinos ao princípio tóxico de Pteridium spp., ainda assim, tem-se verificado a ocorrência de casos de hematúria nessa espécie. De acordo com o levantamento inicial, a HE só ocorre em búfalos com idade a partir de seis anos. Ao exame macroscópico, verificou-se a mucosa da bexiga espessa, com múltiplos focos de lesões ulceradas, exofíticas, papiliformes, verrucosas, pedunculadas. Histologicamente, foram observadas alterações neoplásicas e não neoplásicas semelhantes às descritas nos bovinos com HE. Entre as neoplasias foram encontrados papiloma, carcinoma in situ, carcinoma urotelial (baixo e alto grau), variantes invertida, microcística e trabecular, carcinoma urotelial com diferenciação divergente (escamosa e glandular), carcinoma de células escamosas, linfangioma, hemangioma e hemangiossarcoma. Ocorreu também coexistência entre neoplasias epiteliais e mesenquimais. Não foram detectadas partículas de papilomavírus bovino pelo teste PCR nas amostras de bexiga analisadas.

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.

El compromiso renal en los pacientes pediátricos con enfermedad por el coronavirus 2019 (COVID-19, por su sigla en inglés) varía entre el 10 % y el 80 %. Dado que existe limitada información sobre su pronóstico, se realizó este estudio con el objetivo de describir la evolución en el corto plazo de pacientes a quienes se les detectó compromiso renal durante la internación por COVID-19. Estudio observacional y transversal que incluyó pacientes entre 1 mes y 18 años con COVID-19 con compromiso renal. Se excluyeron aquellos con patología renal conocida. Se identificaron 27 pacientes con afectación renal, en 14 de ellos se pudo realizar seguimiento para estudiar la evolución renal luego de 3 meses del diagnóstico. Todos habían normalizado los niveles de creatinina plasmática durante la internación y al momento del control ambulatorio, realizado a los 145 días (92-193), todos se encontraban normotensos y con hallazgos urinarios normales, excepto uno que persistía con microhematuria. La evolución fue favorable; la mayoría de los pacientes presentaron remisión completa del compromiso renal.
Renal involvement among pediatric patients with coronavirus disease 2019 (COVID-19) ranges between 10 % and 80 %.Given the limited information about its prognosis, the objective of this study was to describe the short-term course of patients in whom renal involvement was detected during hospitalization due to COVID-19. This was an observational, cross-sectional study in patients aged 1 month to 18 years who had COVID-19 and renal involvement. Those with a known kidney disease were excluded. A total of 27 patients with renal involvement were identified; 14 of them were followed-up to study their disease course for 3 months after diagnosis. All of the patients had achieved normal plasma creatinine levels during hospitalization and, at the time of outpatient follow-up, which took place 145 days (92-193) later, all had normal blood pressure and urinary values, except for 1 patient who continued with microscopic hematuria. Course was favorable; in most patients, renal involvement had fully resolved.

Le rein est une des cibles de Covid-19.L'atteinte peut se présenter sous forme d'une insuffisance rénale aigue (5-35% des patients), d'une hématurie (30-40%) et/ou d'une protéinurie (40-65%). Nous rapportons deux cas d'insuffisance rénale aigue due au Covid-19 au Mali. Il s'agit d'une femme de 63 ans et d'un homme de 60 ans, de race noire et tous deux diabétiques. Les circonstances de découverte de l'insuffisance rénale ont été l'oligurie dans les deux cas et l'hématurie macroscopique totale dans le deuxième cas. Conclusion : Les atteintes rénales deviennent de plus de plus fréquentes au cours de l'infection à Covid-19. Nous suggérons de les rechercher systématiquement dès que le diagnostic de cette infection est posé.

Hematúria é uma grave manifestação clínica de doença do sistema urinário, ocorrendo sob as formas micro ou macroscópica. Neste artigo relatam-se dois casos de hematúria macroscópica associada à infecção por Leptospira interrogans sorogrupo Canicola. O exame clínico inicial revelou hematúria macroscópica, taquicardia, taquipneia, febre, elevação do tempo de perfusão capilar, hipomotilidade intestinal, além de icterícia da mucosa oral. Leucocitose, proteinúria, glicosúria, piúria e azotemia foram achados comuns aos dois casos. Teste de Soroaglutinação Microscópica foi realizado para titulação de anticorpos contra Leptospira interrogans. Tratamento incluiu medidas terapêuticas de suporte (fluidoterapia), controle da hematúria e antibioticoterapia. Sete dias após manifestação dos sinais clínicos iniciais, ambos animais receberam alta hospitalar após remissão dos sinais clínicos.
Haematuria is a serious clinical manifestation of urinary system disease, occurring in micro or macroscopic forms. In this article two cases of macroscopic haematuria associated with Leptospira interrogans serogroup Canicolainfection are related. The initial clinical examination revealed macroscopic haematuria, tachycardia, tachypnea, fever, increased capillary perfusion time, intestinal hypomotility, in addition to jaundice of the oral mucosa. Leukocytosis, proteinuria, glycosuria, pyuria and azotemia were common findings in both cases. Microscopic serum agglutination test was performed for titration of antibodies against Leptospira interrogans. Treatment included supportive therapeutic measures (fluid therapy), hematuria control and antibiotic therapy. Seven days after the manifestation of the initial clinical signs, both animals were discharged from the hospital without complications.
