[Evolution aspect of anatomy clinical lesions of urogenital fistula (UGF) in Cocody Teaching Hospital urological unity from 1990 to 2011]. / Aspect évolutif des lésions anatomo-cliniques des fistules urogénitales (FUG) dans le service d'urologie du CHU de Cocody de 1990 à 2011.

PURPOSE: The aim of this study is to compare anatomy pathological lesions seeing in urogenital fistula in Cocody Teaching Hospital between two decades, 1990 to 2000 and 2000 to 2010. MATERIEL AND METHOD: This survey is retrospective and carries on 20 years (January 1990 to December 2011) 190 urogenital fistulas (140 cases between 1990 and 1999; 50 from 2000 to 2011) hospitalized in our unity. Anatomy clinical characteristics of these fistulas were determined by clinical or paraclinical examination. RESULTS: Between 1990 and 1999, fistulas were classified in 20 bladder-uterine fistulas (14.29%), 16 uretro-vaginal fistulas (11.43%) and 104 bladder-vaginal fistulas (74.29%) of whom 80 isolated UGFs and 24 UGFs associated with recto-vaginal fistula. These 104 UGFs were located at: bladder neck 22 cases (21.15%), bladder trigonal 46 cases (44.23%), urethra 14 cases (13.46%). Twenty-two bladder sphincter were destroyed and represented 21.15% of fistula's bladder-vaginal fistula and 15.71% of all UGFs. The average fistula diameter was 3 cm [extremes: 1 and 12 cm]. In 22 cases (15.71%), fistula diameter was more than 10 cm. It was bladder neck and sphincter destruction. Hundred and twenty-six fistulas were isolated (90%). Only 10% (14 cases) were associated. Fistulas were primitive in 85.71% of cases (120/140), recurrent in 7 cases (7.86%) and multi-recurrent (>3 reinterventions) in 9 cases (6.43%). From 2001 to 2011, no bladder-uterine fistulas were seen, but: 6 (13.95%) isolated uretero-vaginal fistulas and 6 (13.95%) uretero-vaginal fistulas associated with bladder-vaginal fistula, 31 (62%) bladder-vaginal fistulas of whom 20 (64.52%) bladder trigonal fistulas, 6 (19.34%) retro-trigonal fistulas and 2 (6.45%) urethral fistulas. Only three (9,68%) recto-vaginal fistulas were associated. The average fistula diameter was 2 cm. The fistulas were isolated in 40 cases (80%) and associated (VVF+uretero vaginal F) in 10 cases (20%). Thirty-five cases (70%) were primitive and 10 cases (20%) recurrent of whom 5 (10%) many recurrent. Fistulas were classified in simple fistula in 7 cases (14%) and complex fistula in 43 cases (86%) CONCLUSION: UGF remained relatively frequent in Cocody Teaching Hospital, but the lesions have favorably evolved in the last decade. Simple type of fistula became more frequent than complex ones. LEVEL OF EVIDENCE: 4.

15-year history of spontaneous appendico-vesical fistula (case report).

Appendicovesical (AVF) fistula is rare complication in the modern era. Only a few cases of AVF were described in the literature of the last decade. AVF is meanly associated with a history of appendicitis. The guiding symptoms are coprosuria and pneumaturia, with recurrent infection of the urinary tract. The accurate pre-operative diagnosis is difficult to make. It usually took at least one year from the onset of symptom to confirm diagnosis. It has been reported a few cases of 15 year history of undiagnosed AVF. We represent a case of EVF, spontaneously developed after treated acute appendicular colic presenting an unusual long - 15 years undiagnosed history, without presenting of typical symptoms. The analyses of disease history after cystoscopy lead to correct pre-operative diagnosis. AVF can develop as a complication not only after untreated appendicitis, but also after "successfully" treated with antibiotics appendicular colic may indicate the presence of an AVF and needs to assessing patient's history and applying cystoscopy and modern examination methods in complex diagnosis issues.

[Unusual presentation of sigmoid diverticulitis. Sigmoid-vesical fistula in sigmoid diverticulitis]. / Ungewöhnliche Präsentation einer Sigmadivertikulitis. Sigmavesikale Fistel auf dem Boden einer Sigmadivertikulitis

A 68-year-old male patient presented with mild tenderness in the suprasymphyseal region, hematuria and dysuria. In this case typical symptoms of a sigmoid-vesical fistula were initially absent. Because of hematuria and the findings provided by urethrocystoscopy, the radiological diagnosis was a bladder tumor. Contrast-enhanced computed tomography with rectal contrast administration provided the decisive information. In addition to sigmoid diverticulitis (fat stranding/centipede sign) in the urographic phase, contrast media was well traceable intraluminally from the bladder through the bladder wall abscess and subsequently in the sigmoid colon.

Preoperative evaluation of enterovesical fistula using magnetic resonance imaging: case report.

We report a case of sigmoido-vesical fistula due to sigmoid diverticulitis. Magnetic resonance imaging enabled us to visualize the fistula itself in the bladder wall. Magnetic resonance imaging was highly effective in making a precise diagnosis and also provided important additional information for the preoperative work-up of the patient.

Progression of pressure ulcer to vesico-cutaneous fistula.

A 72-year-old female known to have diabetes, multiple medical problems, and bedridden with indwelling Foley's catheter. She presented with an ulcer which progressed to a Grade 4 pressure ulcer. She was known to have recurrent urinary tract infection. Contrast study through the fistula revealed a communicating fistula between the left buttock ulcer and the bladder. Conservative way of management was followed due to the overall health status of the patient. She was sent to home with daily dressings, mattress, and an occupational therapy plan. Fortunately, her fistula healed spontaneously after six months. To our knowledge, in addition to the unique presentation and outcome, the case we reported is the first with such communication.

Air in the urine: a mystified patient and a concerned surgeon.

Appendicovesical fistula is a rare type of enterovesical and a very rare complication of acute appendicitis. Herein, we report a case of a 22-year-old man who presented with cloudy urine and pneumaturia with a prior history of acute appendicitis. Imaging techniques including ultrasonography, CT and cystoscopy were performed to diagnose the abnormality. Diagnosis of this fistula is challenging and relies on detailed history and radiological imaging.

[Urinary incontinence revealing vescicouterine fistula: about a case]. / Incontinence urinaire révélant une fistule vésico-utérine: à propos d'un cas.

Vescicouterine fistula (VUF) is a rare lesion accounting for only 4% of all urogenital fistulas. It is most often secondary to cesarean section and forms a connection between the bladder and the uterus. We report the case of a young patient with VUF secondary to cesarean section. This study aims to investigate the clinical and therapeutic features of this disorder.

Multiple lymphomatous diverticulosis and comorbid chronic lymphocytic leukemia: novel manifestations of ileocolic mantle cell lymphoma.

Mantle cell lymphoma (MCL) has tropism for the gastrointestinal tract (GIT) identifiable as multiple polyps and mass lesions throughout the GIT. We describe 2 novel manifestations of MCL. A 60-year-old woman with known chronic lymphocytic leukemia (CLL) had an exophytic mass of the appendiceal orifice. Multiple polypoid masses of the distal ileum were identified in the right hemicolectomy specimen (multiple lymphomatous polyposis). Ancillary studies confirmed the coexistence of the 2 independent lymphoproliferative disorders. A 69-year-old man had recurrent urinary tract infections and pneumatouria caused by a colovesicular fistula complicating diverticulosis coli. Segmental resections of the sigmoid and ileocecum confirmed diverticulosis of the left and right colon. Histology identified infiltrates of MCL confined to the penetrating aspects of colonic diverticula. MCL has not been documented to coexist with CLL. An invaginating morphology of lymphoma, multiple lymphomatous diverticulosis is also a novel presentation. These 2 scenarios expand MCL's known manifestations within the GIT.

Vaginal tumor-vesical fistula detected by dynamic fluorodeoxyglucose-positron emission tomography/computed tomography: A case report.

Preoperative fistulas are rare in patients with bladder mucosa-invading gynecological tumors. This is the first reported case of a vesico-vaginal fistula identified using 2-deoxy-2-[fluorine-18]fluoro-d-glucose positron emission tomography/computed tomography (18F-FDG-PET/CT) in a patient with vaginal cancer. A 61-year-old woman with vaginal cancer underwent 18F-FDG-PET/CT for assessment of the mass and lymph nodes. Assessment was difficult because overlap of FDG uptake occurred on 18F-FDG-PET/CT images obtained 60min after FDG injection. However, dynamic 18F-FDG-PET/CT clearly indicated the presence of a vaginal tumor-vesical fistula. This case illustrates the usefulness of dynamic 18F-FDG-PET/CT imaging when assessing a vesico-vaginal fistula.

[Vesico-sigmoid fistula secondary to diverticulitis: a case report]. / Fistule vesico-sigmoidienne d'origine diverticulaire. A propos d'un cas.

Vesico-sigmoid fistula is a rare complication of colic diverticular disease. It develops when the bladder sticks to an inflammatory colon making of a communication between the bladder and the digestive segment, usually the sigmoid. Liquid usually passes from the colon to the bladder because of the existing pressure gradient. Hence, urinary symptoms are the most frequent. Surgery is the treatment of choice. The present case is about a 72-year-old man who had a total hematuria for 3 months. The diagnosis of a vesico-sigmoid fistula secondary to colic diverticulitis was established by cystoscopy, colonoscopy and cystography. Surgery was underlaken and the postoperative outcome was excellent. Through this case the clinical features, special investigations and treatment of vesico-sigmoid fistula, are reported.

Postcaesarean section uterovesical fistula lined by persistent intermediate trophoblast.

We report a unique case of a postcaesarean section uterovesical fistula lined by intermediate trophoblast. The patient, a 42-year-old woman, presented with cyclical haematuria, and she had had a lower segment caesarean section 1 year previously. She was found to have uterovesical fistula, which was excised. On microscopic examination the fistula tract was lined by intermediate trophoblast characterised by cells with abundant eosinophilic cytoplasm, occasional multiclefted nuclei, and cytoplasmic immunoreactivity for epithelial cytokeratins and human placental lactogen. This finding has not, to our knowledge, been previously described and indicates that the survival of third trimester intermediate trophoblast is independent of pregnancy.

Lymphadenopathy and entero-vesical fistula in Fabry's disease.

A case of a 55-year-old man with known Fabry's disease, complicated by entero-vesical fistula and associated with enlarged mesenteric lymph nodes, is reported. Histopathologic and ultrastructural findings of the involved lymph nodes are described, and pathogenesis of the entero-vesical fistula is briefly discussed. This is the first case, to the authors' knowledge, of urologic complication in Fabry's disease.

Seminoma metastatic to the prostate resulting in a rectovesical fistula.

We report an unusual presentation of metastatic seminoma within the prostate gland. Histological diagnosis was obtained using trans-rectal ultrasound guided prostatic biopsy. The patient developed a rectovesical fistula after ten weeks of chemotherapy, which healed following a complete radiological response to treatment

Primary Epstein-Barr virus-associated Hodgkin disease of the ileum complicating Crohn disease.

We describe a case of primary Hodgkin disease of the terminal ileum in a 38-year-old man with Crohn disease of 24 years' duration. The infiltrate was located in an ulcerated fistula involving the terminal ileum and urinary bladder. Reed-Sternberg cells and their variants were characteristically positive for CD15, fascin, and CD30 and showed focal positivity for CD20. Epstein-Barr virus messenger RNA was also detected in the neoplastic cells. Staging revealed no evidence of other lymph node or organ involvement. Although rare, primary gastrointestinal Hodgkin disease arising in the setting of Crohn disease may have a stronger association with Epstein-Barr virus infection than conventional Hodgkin disease.

Vesicouterine fistula in pregnancy: a case report.

BACKGROUND: Vesicouterine fistula is a rare complication of Caesarean delivery. This is the third known report of vesicouterine fistula diagnosed during pregnancy. CASE: Linda (pseudonym), a 28-year-old woman in her second pregnancy, having had a Caesarean delivery in her first pregnancy, was admitted to the delivery unit with possible preterm ruptured membranes at 23 weeks' gestation. She also complained of a fluid-filled sac bulging from her introitus during her admission assessment. Diagnosis of premature rupture of membranes was confirmed by a positive nitrazine paper test and appearance of ferning during microscopic evaluation of vaginal fluid. Cystoscopy, performed 3 days after admission, demonstrated ballooning of amnion into the bladder. At 24 weeks' gestation, the woman had a precipitous vaginal breech delivery. Two months later, the fistula was successfully repaired through a transabdominal route. CONCLUSION: Although uncommon in pregnancy, vesicouterine fistula should be considered in women who present with urinary incontinence or recurrent urinary tract infections after a lower transverse Caesarean section. Evaluation in pregnancy is usually limited to cystoscopy. Treatment is usually surgical and is often delayed until 2 to 3 months following delivery.

Congenital pouch colon associated with segmental dilatation of the colon.

A 1-day-old boy who presented with an anorectal malformation (ARM) was found to have a segmental dilatation of the colon (SDC) associated with a typical congenital pouch colon (CPC) malformation. The distal colonic pouch terminated in a high colovesical fistula. The posterior portion of the perineal raphé was duplicated and ended in 2 anal dimples. Both dilated segments of the colon were excised. The similarity between CPC and SDC is highlighted, and the possible embryogenesis of both conditions is discussed.

Prepubic dermoid sinus: possible variant of dorsal urethral duplication (Stephens type 3).

The authors present the case of 4-month-old girl with a midline prepubic sinus extending from the skin overlying the pubis to the superior surface of the bladder, and continuing to the umbilicus via the median umbilical ligament. The distal portion of the exicised sinus was surrounded by concentric bundles of collagen and smooth muscle with minimal inflammatory infiltrates, which suggests a developmental origin. According to Stephens' classification, the sinus appears to be a variant of dorsal urethral duplication of Stephens type 3.

Umbilical evagination of the urinary bladder in a neonatal filly.

An 8-hour-old Standardbred filly was evaluated because of an enlarging umbilical mass and stranguria. It was suspected that the mass was the urinary bladder; this was confirmed on surgical exploration of the abdomen. Despite a normal umbilical ring, the bladder had descended and partially everted through its urachal communication with the umbilical stalk. Partial cystectomy and umbilical resection were performed and resulted in an excellent clinical outcome. Evagination of the urinary bladder via the umbilicus has rarely been described in human infants, and, to our knowledge, it has not been reported in the veterinary literature.
