Persistencia simultánea del conducto uraco y onfalomesentérico en un paciente adulto, reporte de caso / Simultaneous persistence of the urachus and vitelline ducts in an adult patient, case report / Persistência simultânea de úraco e do ducto onfalomesentérico em um paciente adulto: relato de caso

Introducción. La patología umbilical es un tema frecuente en el ámbito pediátrico, la presentación clínica de una fístula umbilical hace pensar en dos patologías mencionadas en la literatura de manera independiente; la primera es la persistencia del conducto onfalomesentérico y la segunda es la persistencia del remanente del uraco producto del fracaso en el cierre de las estructuras embrionarias. Su presencia en adultos es infrecuente y no existen datos estadísticos acerca de su presentación conjunta en población pediátrica o adulta, solo algunos pocos reportes de caso. El diagnóstico se basa principalmente en la sospecha clínica, depende en gran manera del examen físico al evidenciar secreción a través del ombligo al realizar esfuerzos o maniobras de Valsalva. Objetivo. Mostrar un caso infrecuente de la presentación simultánea del conducto de uraco y onfalomesentérico en un paciente adulto. Reporte de caso. Paciente femenina de 24 años de edad con antecedentes de infecciones urinarias y celulitis periumbilicales a repetición. Se sospecha un conducto persistente onfalomesentérico por lo que es sometida a un procedimiento quirúrgico en el que se encontró incidentalmente la persistencia simultánea del conducto onfalomesentérico y persistencia del uraco. Discusión. La persistencia del conducto onfalomesentérico o la persistencia del uraco de forma individual es poco frecuente en adultos, y es aún más raro la persistencia simultánea de ambos conductos; la presencia simultánea de ambos conductos es reportada principalmente en menores de dos años. Conclusiones. La persistencia de estos conductos es rara en adultos y representa un reto diagnóstico para el clínico.

Introduction. Umbilical pathology is a common topic in the pediatric sphere. The clinical presentation of an umbilical fistula leads to the consideration of two pathologies independently reported in literature. The first is a persistent vitelline duct and the second is a persistent urachal remnant as a result of the embryonic structures' failure to close. They are uncommon in adults and there are no statistical data about their presentation together in the pediatric or adult population, only very few case reports. The diagnosis is mainly based on clinical suspicion. It largely depends on a physical examination noting secretion through the navel when straining or performing Valsalva maneuvers. Objective. Show an uncommon case of the simultaneous presentation of the urachus and vitelline ducts in an adult patient. Case report. Female patient aged 24 years with a background of repeated urinary tract infections and periumbilical cellulitis. A persistent vitelline duct is suspected. Therefore, the patient is subject to a surgical procedure in which the simultaneous persistence of the vitelline duct and the urachus was found incidentally. Discussion. The persistence of the vitelline duct or the persistence of the urachus individually is uncommon in adults, and the simultaneous persistence of both ducts is even rarer. The simultaneous presence of both ducts is reported mainly in infants aged under two years. Conclusions. The persistence of these ducts is rare in adults and poses a diagnostic challenge for clinicians.

Introdução. A patologia umbilical é um tópico frequente no cenário pediátrico; a apresentação clínica de uma fístula umbilical faz pensar em duas patologias mencionadas na literatura de forma independente; a primeira é a persistência do ducto onfalomesentérico e a segunda é a persistência do úraco como resultado da falha no fechamento das estruturas embrionárias. É pouco frequente sua presença em adultos e não há dados estatísticos sobre sua apresentação conjunta em população pediátrica nem adulta, apenas alguns poucos relatos de caso. O diagnóstico baseia-se principalmente na suspeita clínica, dependendo em grande parte do exame físico ao evidenciar uma secreção pelo umbigo quando realizar esforço ou manobra de Valsalva. Objetivo. Mostrar um caso infrequente de apresentação simultânea do úraco e ducto onfalomesentérico em um paciente adulto. Relato de caso. Paciente do sexo feminino, 24 anos, com histórico de infecções urinárias e celulite periumbilical recorrentes. Suspeita-se de um ducto onfalomesentérico persistente, portanto ela é submetida a um procedimento cirúrgico no qual encontrou-se a persistência do ducto onfalomesentérico e a persistência de úraco simultaneamente. Discussão. A persistência do ducto onfalomesentérico e a persistência de úraco individualmente é rara em adultos, e a persistência simultânea de ambos os ductos é ainda mais rara; esta presença simultânea é relatada principalmente em crianças menores de dois anos de idade. Conclusão. A persistência desses ductos é rara em adultos e representa um desafio diagnóstico para o profissional de saúde clínico.

Complete androgen insensitivity syndrome associated with vesical fistula:a case report and literature review / 北京大学学报(医学版)

Androgen insensitivity syndrome (AIS) is a very uncommon genetic disorder that results from the resistance of androgen receptor (AR) to androgen, which influences the formation of the male genitalia and in turn presents with female phenotype.Surgical resection of undesceaded testicle and different kinds of genitoplasty are crucial methods to correct the deformity of reproductive system, as well as hormone replacement therapy, which is an essential therapy for postoperational rehabilitation in AIS patients.A 43-year-old patient, who was socially female, was first admitted to gastroenterology department due to recurrent ascites and occasional abdominal pain with unknown origin.Taking physical examination, ultrasonography, karyotype analysis and sex hormone levels into consideration, the overall manifestations revealed the typical clinical features of complete androgen insensitivity syndrome.After that she was transferred to urology department for laparoscopic gonadectomy.During the surgery, doctors found that there was a vesical fistula on the upper wall near the conjunction between the bladder and ligamenta umbilicale medium, which explained the recurrent ascites for more than 4 years.After resecting the testicles and the tissues around the vesical fistula for histopathology, the result suggested Sertoli cell adenoma, hyperplastic Leydig cells and urothelium atypical hyperplasia.Hormone replacement therapy was given right after discharge.The hormone levels of follicle-stimulating hormone, luteinizing hormone, estradiol and progesterone were modulated by the dysfunction of androgen production after gonadectomy and hormone replacement therapy together with psychotherapy could stabilize her hormone levels and improve the quality of her life.The patient was suspicious of AIS family history and the pedigree was made to analyze her family which was possibly X-linked recessive pattern.We propose three possible hypotheses of the fistula, which are direct surgical injury, recurrence of bladder cancer and congenital urachal anomalies.But whether it is relevant between urachal anomalies and AIS is yet to be discovered.

Vesicoenteric Fistula due to Bladder Squamous Cell Carcinoma

Vesicoenteric fistula is a rare complication of bladder squamous cell carcinoma. We report the case of a 70-year-old male who complained of painless, total gross hematuria. Abdominopelvic computed tomography (CT) revealed an approximately 2.7-cm lobulated and contoured enhancing mass in the bladder dome. We performed partial cystectomy of the bladder dome after transurethral resection of the bladder. The biopsy result was bladder squamous cell carcinoma, with infiltrating serosa histopathologically, but the resection margin was free. Postoperatively, follow-up CT was done after 3 months. Follow-up CT revealed an approximately 4.7-cmx4.0-cm lobulated, contoured, and heterogeneous mass in the bladder dome. A vesicoenteric fistula was visible by cystography. Here we report this case of a vesicoenteric fistula due to bladder squamous cell carcinoma.

Infecção do trato urinário de repetição por fístula enterovesical secundária a doença diverticular do cólon: um relato de caso / Recurrent urinary tract infection due to enterovesical fistula secondary to colon diverticular disease: a case report

INTRODUÇÃO: As fístulas enterovesicais (FEV) são comunicações patológicas entre a bexiga e as alças intestinais pélvicas. Trata-se de uma rara complicação decorrente de doenças inflamatórias e neoplásicas da pelve, além de casos resultantes de iatrogenia, e associa-se a altos índices de morbimortalidade. RELATO DO CASO: Trata-se de um paciente de 61 anos com um quadro de dor e distensão abdominal, vômitos, parada de eliminação de fezes e flatos. APP: Hipertenso, diabético, com antecedentes de disfunção vesical e infecções do trato urinário de repetição (ITUr) nos últimos três anos. Por meio da realização de ressonância magnética de abdômen e pelve, diagnosticou-se FEV associada à doença diverticular (DDC) do sigmoide. A conduta estabelecida consistiu em colectomia parcial com rebaixamento de colo e cistectomia parcial com colocação cirúrgica de cateter duplo jota à esquerda. DISCUSSÃO: Embora consista de afecção primária do trato digestivo, normalmente o paciente com DDC associada a FEV procura atendimento médico em decorrência de queixas do trato urinário. Nesse caso, a demora no diagnóstico fez com que a queixa principal fosse do trato digestivo e com antecedentes de queixas urinárias. CONCLUSÃO: Apesar de pouco frequente, a ocorrência de ITUr associada à DDC deve ser sempre considerada no diagnóstico diferencial das ITUr pela alta morbimortalidade.

INTRODUCTION: Enterovesical fistula are pathological connections between the bladder and pelvic intestinal segments. It consists of a rare complication of neoplastic and inflammatory pelvic disorders, in addition to iatrogenic or traumatic injuries, and correlates with both high morbidity and mortality indexes. CASE REPORT: Male patient, 61 years old, admitted at the hospital clinics featuring abdominal pain and distension, vomiting and fecal retention. Patient's pathological precedents include high blood pressure, diabetes mellitus, vesical dysfunction and recurrent urinary tract infection on the past three years. Magnetic resonance imaging of abdomen and pelvis revealed enterovesical fistula in association with colon diverticular disease of the sigmoid. Management of choice consisted of partial colectomy with bowel lowering and partial cystectomy with surgical double-J stent insertion. DISCUSSION: Although consisting of a gastrointestinal primary affection, patients with enterovesical fistula usually search for medical help charging urinary tract features. In this particular case, our patient was admitted with gastrointestinal symptoms, reasoned by diagnostic delay, as the patient had already attended at multiple centers with urinary symptoms. CONCLUSION: Despite being an unusual affection, recurrent urinary tract infection associated with colon diverticular disease must always be considered at differential diagnosis of recurrent urinary tract infection as it concurs with high morbidity and mortality.

Hematuria fatal por fístula ilíaco-vesical, reporte de caso / Lethal hematuria du to ilio-vesical fistula. Case report

Las fístulas ilíaco-vesicales son una rara complicación de los aneurismas de la aorta abdominal. Se presenta el caso de un paciente de 76 años con aneurisma roto de arteria ilíaca contenido en vejiga, que se manifestó por dolor abdominal y hematuria, y en quien se sospechó por tomografía una fístula ilíaco-vesical, la cual se confirmó durante la cirugía. El paciente falleció a los 20 días del procedimiento, por shock mixto séptico.

Iliocovesical fistulas are infrequent complications of abdominal aortic aneurysms (AAA). We report the case of a 76 year-old male with a contained ruptured aneurysm of the iliac to the urinary bladder. Complaints on presentation were abdominal pain and hematuria; suspected iliacovesical fistula was reported on a computed tomography (CT) scan, which was confirmed during laparotomy. The patient died 20 days after the procedure due to mixed distributive septic shock.

Bladder Reconstruction Using Bovine Pericardium in a Case of Enterovesical Fistula

The use of graft materials in bladder mucosa has been examined in animal models, but debate exists over which materials are effective. Intestine has been used as a substitute in augmentation cystoplasty for patients with neuropathic bladder, but serious adverse effects of the operation have occurred in some instances. We report a case of a successful repair of an enterovesical fistula by use of bovine pericardium. The patient has remained well for 2.5 years. We suggest that bovine pericardium may be a suitable option as a bladder substitute.

Vesico-Acetabular Fistula and Urolithiasis in the Hip Joint Cavity due to Persistent Bladder Entrapment after Acetabular Fracture

We report a rare case of vesico-acetabular fistula due to an improperly treated pelvic fracture with urinary stone formation in the joint cavity. This complication was related to an unrecognized mechanism of bladder wall entrapment in the acetabular floor defect during weight bearing. This situation led to several mistreatment decisions in our case and should be always considered by urologists dealing with patients after major pelvic trauma. In this case report, we analyze the publications related to this problem, discuss the main mechanisms of bladder wall damage after acetabular fracture, and propose tips for diagnosis and treatment.

Vesico-appendiceal fistula in a mucinous adenocarcinoma of the appendix / Fístula vésico-apendicular em adenocarcinoma mucinoso do apêndice

BACKGOUND: A rare case of vesicoappendiceal fistula secondary to mucinous adenocarcinoma of the appendix is presented. CASE REPORT: A 62-year-old man with a one year history of recurrent urinary tract infections. After two months he developed pneumaturia and fecaluria. An abdominal and pelvic computed tomography demonstrated a trans-mural mass in the posterior wall of the bladder with a vesicoenteric fistula leading to the terminal ileum. Laparotomy revealed a tumor arising from the appendix contiguous with the bladder posterior wall. The bladder was opened and a large fistula and tumor on the posterior bladder wall near the trigone was identified. Frozen pathological analysis showed a mucinous adenocarcinoma. En-bloc right hemicolectomy and partial cystectomy, preserving bladder trigone was performed. After manipulating the tumor, grossly leakage of mucinous materials occurred into the pelvic cavity. A peritoneal washing with a mytomicin solution at 42º C was then performed, to prevent peritoneal seeding. The patient had a prolonged postoperative ileus and was discharged at the 15th day. Five months after the procedure the patient was recieving chemotherapy with 5-fluoracil and leucovorin and there was no signs of recurrent disease. CONCLUSION: The presentation with vesico-appendiceal fistula is extremely rare with only a few cases reported in the literature. Knowledge of different types of neoplasm and appropriate treatment allows the surgeon to provide patients optimal care referring to specialized centers whenever appropriate.

INTRODUÇÃO: Apresenta-se raro caso de fístula vésico-apendicular secundária a adenocarcinoma mucinoso do apêndice. RELATO DE CASO: Paciente masculino de 62 anos com história de um ano de infecções urinárias de repetição. Após dois meses desenvolveu pneumatúria e fecalúria, sendo indicada tomografia computadorizada de abdômen que mostrou massa trans-mural na parede da bexiga, com fistula vésico-entérica para região do íleo terminal. A laparotomia revelou tumoração surgindo do apêndice cecal, em continuidade com a parede posterior da bexiga. A mesma foi aberta, sendo identificada grande fistula e material tumoral até próximo ao trígono vesical. A biópsia de congelação identificou adenocarcinoma mucinoso. Realizada hemicolectomia associada à cistectomia parcial em bloco, com preservação do trígono vesical. Houve extravasamento de mucina para a cavidade pélvica pela manipulação. Optado por lavagem peritoneal com solução de mitomicina a 42º C para prevenir disseminação peritoneal. O paciente evoluiu com íleo prolongado pós-operatório, tendo alta hospitalar no15º dia. Cinco meses após o procedimento encontrava-se em quimioterapia com 5-fluouracil e leucovorin, sem sinais de doença recidivante. CONCLUSÃO: A presença de fístula vésico-apendicecal é extremamente rara, tendo poucos casos relatados na literatura. O conhecimento dos diferentes tipos de neoplasias e seus tratamentos adequados permite ao cirurgião oferecer melhor cuidado ao paciente.

A Case of Bladder Rupture after Normal Vaginal Delivery

Spontaneous rupture of the bladder is usually associated with a history of recent trauma, instrument injury, or existing bladder disease. However, there are also occasional reports of bladder rupture associated with pregnancy, most of which are complications of cesarean section. However, spontaneous bladder rupture following normal vaginal delivery is very rare. Patients with bladder rupture need a rapid, sensitive diagnosis and treatment because of a high risk of mortality and morbidity. We report a case of bladder rupture after normal vaginal delivery, which was successfully managed. A patient with small bladder rupture and ascites after normal vaginal delivery was treated by urethral catheterization and use of antibiotics, without operation.
