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.

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.

[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.

Meckel's diverticulum: an exceptional cause of vesicoenteric fistula: case report and literature review.

UNLABELLED: Meckel's diverticulum is the most common congenital malformation of the gastrointestinal tract. It can cause complications in the form of ulceration, hemorrhage, intussusception, intestinal obstruction, perforation and, very rarely, vesicodiverticular fistulae as noted in six previously reported cases. 66-year-old woman was presented with an enterovesical fistula. Exploratory laparotomy revealed a vesico-diverticular fistula resulting from a perforated Meckel's diverticulum. Pathologic examination revealed that the diverticulum did not contain ectopic gastric or pancreatic tissue. The patient underwent a diverticulectomy and had an uneventful postoperative course. Unlike four of the six previously reported cases, our patient had no coexisting bowel or bladder disease occurring with her vesico-diverticular fistula. CONCLUSION: This is only the third reported case of a vesico-diverticular fistula resulting from a perforated Meckel's diverticulum that did not contain ectopic tissue.

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.

Contrast-material-enhanced MR urography in evaluation of postoperative lower urinary tract fistulae and leakages.

Urinary fistulas and leakages of lower urinary tract are serious complications of various surgical procedures. Radiologists need to have enough information about these situations to perform precise diagnosis and treatment. Various techniques [such as intravenous pyelography, ultrasound, computed tomography (CT), CT urography, cystoscopy, cystography and magnetic resonance (MR) imaging] are used for the diagnosis of these conditions. Application of all these techniques reduces the comfort and cooperation of the patients and increases the cost. Here we present four postoperative patients with lower urinary tract fistula or leakage. To the best of our knowledge, there is no report regarding the use of contrast-material-enhanced MR urography (CE-MRU) in the demonstration of postoperative lower urinary tract fistulae and leakages. In conclusion, CE-MRU could show the existence and location of the urinary fistulae and leakages clearly without the need for another investigation technique, as described in our patients. Also, CE-MRU is a safe and relatively inexpensive technique that avoids exposure to radiation as well as nephrotoxic and more allergic contrast-material administration.

[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.

Cesarean delivery-related fistulae in the Democratic Republic of Congo.

OBJECTIVE: To compare the characteristics of urogenital fistulae after cesarean delivery with those after spontaneous vaginal delivery. METHODS: A retrospective analysis of hospital records of 597 consecutive patients with a urogenital fistula who received treatment at Panzi Hospital, Bukavu, Democratic Republic of Congo, during 2005-2007. RESULTS: Of 576 women with an obstetric fistula, 229 (40%) had had a cesarean delivery; 55 (24%) of the 229 fistulae were considered to be iatrogenic. The distribution of risk factors (age, stature, parity, and labor duration) was similar to that among 226 women with a spontaneous vaginal delivery, but the odds ratios for having a ureterovaginal or a vesicouterine fistula were 11.9 (95% confidence interval [CI] 2.8-51.2) and 9.5 (95% CI 2.8-31.9), respectively. Vesicovaginal fistulae with cervical involvement were also significantly more frequent in the cesarean delivery group. The fistulae in this group had less surrounding fibrosis and there was less treatment delay. Stillbirth rates were 87% (cesarean delivery) and 95% (spontaneous vaginal delivery). CONCLUSION: The data indicate that cesarean delivery-related fistulae are a separate clinical entity. Focus on this condition is important for fistula prevention and provision of adequate obstetric care, particularly for training in surgery and alternative delivery methods.

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.

The colovesical fistula in congenital pouch colon: a histologic study.

PURPOSE: The aim of this study was to perform a detailed histopathologic examination of the terminal colonic pouch and the colovesical fistula (CVF) excised during surgical management of male patients with the more severe forms (types I/II) of congenital pouch colon (CPC) associated with anorectal agenesis. METHODS: From January 2005 to December 2006, 25 male patients with types I/II CPC underwent abdominal exploration with dissection of the terminal portion of the colonic pouch and associated CVF till the bladder, division-ligation of the fistula, and excision of the colonic pouch. In 6 of the 25 patients, a complete dissection of the fistula to the bladder was possible, and in them, the terminal portion of the colonic pouch and the CVF were subjected to detailed histopathologic examination. The 6 patients included 3 newborns in whom this surgery was performed as a primary procedure, and 3 patients aged 3 months, 15 months, and 2 years, respectively, in whom a window colostomy of the pouch had earlier been performed. After due processing, multiple sections from the specimens were stained using the routine H&E method and examined under the microscope under different magnifications. RESULTS: In 4 specimens, the epithelial lining of the CVF consisted of transitional stratified epithelium with underlying anal/urethral glands. In 2 specimens, obtained from patients 15 months and 2 years old, respectively, the lining was of nonkeratinizing, stratified squamous epithelium. Other findings included aganglionosis in the muscle layers (n = 2), submucosal and subserosal fibrosis (n = 1), and thickening of muscle layers in the fistulous portion, suggestive of the presence of an internal sphincter (n = 2). CONCLUSIONS: The CVF in patients with types I/II CPC shows histologic features of the normal anorectal canal.
