Correlation between congenital pelvic floor muscle development assessed by magnetic resonance imaging and postoperative defecation.

OBJECTIVE: Children with congenital anorectal malformation (CAM) experience challenges with defecation. This study aims to assess defecation in preschool-age children with CAM and to evaluate the correlation between pelvic floor muscle developed assessed by magnetic resonance imaging (MRI) and postoperative defecation. METHODS: We collected clinical data and MRI results from 89 male children with CAM. The bowel function scores for children with Perineal (cutaneous) fistula, Rectourethral fistula(Prostatic or Bulbar), and Rectovesical fistula were computed. MRI scans were subjected to image analysis of the striated muscle complex (SMC). The association between pelvic floor muscle score and bowel function score was examined using the Cochran-Armitage Trend Test. RESULTS: We observed that 77.4% of the SMC scores by MRI for Perineal fistula were good. The Rectourethral fistula SMC score was 40.6% for moderate and 59.4% for poor. The SMC score for Rectovesical fistula was 100% for moderate. Furthermore, 77.4% of patients with Perineal fistula had bowel function scores (BFS) ≥ 17 points. Among those with Rectourethral fistula and Rectovesical fistula, 12.5% and 0 had BFS ≥ 17 points, respectively. An analysis of muscle development and bowel function in patients with Rectovesical fistula, Rectourethral fistula, and Perineal fistula revealed a correlation between SMC development and BFS. Subgroup analysis showed that the Perineal fistula had statistical significance; however, the Rectourethral fistula and Rectovesical fistula were not statistically significant. CONCLUSION: A correlation exists between pelvic floor muscle development and postoperative defecation in children with Perineal fistula.

Jejunovesical Fistula Diagnosis After Normal Vaginal Delivery: A Case Report.

Enterovesical fistula represents an abnormal communication between the intestine and bladder. The causes are diverticulitis (56.3%), malignant tumours, which are located mainly in the intestine (20.1%), and Crohn's disease (9.1%). Other causes include iatrogenic injury (3.2%); trauma; foreign bodies in the intestinal tract; radiotherapy; chronic appendicitis; tuberculosis; and syphilis. Normal vaginal delivery as a cause for enterovesical fistula has not been reported in many publications yet. We report a case of a 30-year-old female, who developed an jejunovesical fistula after normal vaginal delivery. It was diagnosed after diagnostic cystoscopy and computed tomography of the abdomen and pelvis. There was jejuno-vesical fistula. Resection of the segment of the jejunum with side-to-side anastomosis with bladder repair was done. A follow-up cystogram was done which showed no contrast extravasation into the peritoneum. The patient was followed up for 9 months after surgery. Keywords: case reports; fistula; jejunum; urinary bladder.

Uterovesical fistula and its treatment in Sub-Saharan Africa.

AIM:  Aim of the study to summarize the current information on diagnostic and treatment options for uterovesical fistula as a consequence of iatrogenic complication. Methods: Literature review of available information on surgical treatment options for uterovesical fistula resulting from previous caesarean section and comparison with our own experience in the developing world. Conclusion: Uterovesical fistula is an abnormal communication between the bladder and uterus. The cause of this pathology in most cases is an iatrogenic complication, most commonly arising after a caesarean section. The incidence of this pathology varies significantly geographically. In developed countries, these fistulas are rather rare. On the other hand, in developing countries, uterovesical fistulas are more common with a significant impact on the subsequent life of the patient due to generally inaccessible health care.

Utilization of point-of-care ultrasound to evaluate for enterovesical fistula.

Enterovesical fistula formation is a relatively rare disease process although a common complication for patients with inflammatory bowel disease (IBD), notably Crohn's disease. Enterovesical fistulas most commonly arise from diverticulitis (65-80%), cancer (10-20%), or Crohn's disease (5-7%). An increasing amount of evidence supports the use of ultrasonography as the primary imaging method for the monitoring of complications in individuals with a documented history of IBD. Our case report presents a 30-year-old female with a history of Crohn's disease who presented to the Emergency Department with concern for possible enterovesical fistula formation. Using bedside gray-scale ultrasonography, a fistulous tract clearly visualizing air bubbles and fecal matter actively moving from bowel to the bladder through the fistula was visualized confirming the diagnosis of an enterovesical fistula. While CT imaging is instrumental in identifying mural and extramural complications of IBD, performing ultrasonography in patients with IBD serves as an efficient, inexpensive, and noninvasive diagnostic aid for the diagnosis of enterovesical fistula.

Enterovesical Fistula in a Lymphoma Patient Revealed by FDG PET/CT With an Oral Contrast Agents.

ABSTRACT: A 60-year-old man with colonic diffuse large B-cell lymphoma was referred for FDG PET/CT for initial staging. He was suspected of enterovesical fistula. After oral administration, large amounts of contrast agents accumulated in the bowel lumen and leaked into the bladder through a well-marked fistulous tract. Corresponding to the fistula, a linear pattern of FDG uptake extended from the bladder into the colonic lumen, and the measured SUV max inside the lesion was as high as that of the urinary bladder. Cystography confirmed the presence of the enterovesical fistula.

Iatrogenic enterovesical fistula secondary to a permanent urinary catheter.

An enterovesical fistula is a rare entity resulting from inflammatory, neoplastic and iatrogenic processes. It can manifest clinically as pneumaturia and recurrent urinary tract infections. Its diagnosis is supported by imaging examinations and its treatment is primarily surgical.

Erudition from primary posterior sagittal anorectoplasty for anorectal malformations over two decades.

PURPOSE: Perioperative and early post-operative outcomes of Primary Posterior sagittal anorectoplasty (P-PSARP) were evaluated. METHOD: Retrospective analysis of cases who underwent P-PSARP from 2004 to 2019 was done. Perioperative care, management, complications, voluntary bowel movement, soiling and constipation, graded by Krickenbeck criteria were studied. RESULTS: One hundred fifty six patients (134 girls) underwent P-PSARP at median age of 5 months (3 months to 14 years) in girls and 5(1-10) days in 21 boys. One male cloaca was operated at 5 months age. Of 20 boys, 5, 8, 4, 3 had rectobulbar urethral fistula, rectoprostatic urethral fistula, bladder neck fistula and male cloaca. Girls had vestibular fistula, rectovaginal fistula, vulval anus, anterior ectopic anus, pouch perineal fistulae and posterior anus with H type fistula in 114, 7, 6, 5, 1 and 1. Complications included wound infection, excoriation, oedema, mucosal prolapse, anal stricture, anal retraction and mortality in 6, 4, 5, 4, 4, 1 and 1, respectively. 35/155(12 neonates) required postoperative dilatations for 5(1-12) months. At follow-up, 96/114(84.2%) had voluntary bowel movements. 46/155 (29.7%) and 9/155 had constipation and soiling. 32:14:0 had grade 1:2:3 constipation, treated with diet (grade 1) and laxatives (grade 2) respectively. 4:3:2 had grade 1:2:3 soiling for initial 3 months, treated with bowel management programme. CONCLUSION: P-PSARP is feasible, subject to proper case selection and good perioperative care, once learning curve is achieved.

Surgical Management and Outcome of Entero-Urinary Fistula Complicating Crohn's Disease: A Single Center Study.

BACKGROUND: Entero-urinary fistulas (EUF) are a rare complication of Crohn's disease (CD), observed in 1.6 to 7.7%. The management of EUF complicating CD is challenging. We aimed to report the outcome and surgical management of EUF in CD. METHODS: A retrospective chart review was performed in all CD patients with EUF who underwent surgery in our center between January 2012 and December 2021. Patient demographics, preoperative optimization, surgical management, postoperative complications, and follow-up information were collected from a prospectively maintained database. RESULTS: A total of 74 eligible patients were identified. The median interval between CD diagnosis and EUF diagnosis was 2 (0.08-6.29) years. Patients with EUF presented with pneumaturia (75.68%), urinary tract infections (72.97%), fecaluria (66.22%), and hematuria (6.76%). Fistulae originated most commonly from the ileum (63.51%), followed by the colon (14.86%), the rectum (9.46%), the cecum (2.70%), and multiple sites (9.46%). The EUF symptoms, weight, nutritional status, laboratory results were significantly improved after preoperative optimization. The absence of EUF symptoms was observed in 42 patients after the optimization and only 9 of which required bladder repair. However, 19 of 32 patients whose symptoms did not resolve required bladder repair (P = 0.001). Only 1 patient developed a bladder leakage in the early postoperative period and 3 patients experienced recurrent bladder fistula. CONCLUSIONS: Surgical management of EUF complicating CD is effective and safe, with a low rate of postoperative complication and EUF recurrence. Preoperative optimization, which is associated with the resolution of urinary symptoms and improved surgical outcomes, should be recommended.

Vesicouterine Fistula After Cesarean Delivery at Full Cervical Dilation.

IMPORTANCE: Vesicouterine fistula (VUF) is an iatrogenic consequence of cesarean section in the vast majority of cases. The worldwide increase of cesarean delivery rates is likely to be accompanied by a rise of this complication, and surgery is the mainstay treatment. OBJECTIVE: The aim of the study is to assess current evidence on VUF pathogenesis and management. STUDY DESIGN: The study is a case report and literature review on PubMed and Embase spanning over the past 2 decades. RESULTS: An early VUF developed after a cesarean section at full cervical dilation and concurrent incidental bladder injury. A transabdominal extravesical repair was performed 3 months after cesarean delivery. Both the cystotomy and hysterotomy were repaired in a double-layer fashion with no interposition flap. A contemporary literature review including 25 patients showed that VUF was repaired transabdominally in 21 patients (84%), and an open approach was adopted in 18 patients (85.7%). In most patients, the uterine side was closed with a single-layer suture and an interposition flap was used to reinforce the repair. Concomitant hysterectomy was performed in 6 patients (24%). Overall, successful term pregnancies were reported in 2 patients after VUF repair. CONCLUSIONS: Vesicouterine fistula is a rare event and is commonly associated with cesarean sections, especially those with a concurrent bladder injury. Careful and meticulous surgical technique may prevent the occurrence of this condition. Delayed repair and double-layer closure of both bladder and uterus, with or without an interposition flap, are recommended.

Unique case of colovesical fistula in a renal allograft recipient.

Colovesical fistula is commonly suspected in cases of diverticular disease, malignancy, trauma, iatrogenic injury or radiotherapy. In a case of allogenic live related transplant, this is rarely expected, especially after 20 years. The presence of gas in the bladder in the absence of history of instrumentation of urinary tract should prompt us to evaluate for colovesical fistula. Pneumaturia, faecaluria and recurrent urinary tract infection are tell-tale features of colovesical fistula, and when patients who are renal allograft recipient present with them, it should prompt a proper workup and swift surgical management, since the outcome is uniformly favourable. From our knowledge in this realm, we know that these are immunocompromised patients and have a high tendency to develop risk factors like malignancy and/or diverticular disease and eventually form colovesical fistula. An expected time period could be from 2 months to 6 years. But in our case, fistula formation occurred long after peak corticosteroid action, in the absence of conventional aetiologies.

An unusual presentation of penetrating bladder injury with vesicocutaneous fistula: a case report.

BACKGROUND: Blunt trauma to the urinary bladder is common with penetrating injury being a rare occasion. Most common entry pint for penetrating injuries includes buttock, abdomen and perineum with thigh being rare. There are a number of complications that may develop as a result of penetrating injury with vesicocutanous fistula being a rare occurrence that usually presents with typical sign and symptoms. CASE PRESENTATION: We present a rare case of penetrating bladder injury through medial upper thigh as an entry point that had complicated into vesicocutaneous fistula with atypical presentation of long-standing pus discharge that had been managed by incision and drainage several times with no success. MRI demonstrated a presence of fistula tract and a foreign body (piece of wood) in-situ confirmed the diagnosis. CONCLUSION: Fistulas are a rare complication of bladder injuries and can cause negative impact on the quality of life of patients. Delayed urinary tract fistulations and secondary thigh abscesses are uncommon therefore a high index of suspicion is needed for early diagnosis. This case emphasizes the importance of radiological tests in aiding the diagnosis and ultimately proper management.

Inferior Vesical Fissure-A Rare Variant of Exstrophy Bladder: Case Report With Literature Review.

Exstrophy variants are uncommon developmental anomalies of the bladder; the variants involving only the bladder neck are extremely rare. There are only three case reports of inferior vesical fissure (IVF) to date, and usually it's uncommonly associated with other malformations. A combination of inferior vesical fistula (IVF) as an exstrophy variant with urethral atresia and anorectal malformation has not been described previously. We report a case of IVF in a 4-year-old male previously operated for anorectal malformation who was managed with fistula closure with bladder neck reconstruction of lay open of stenosed urethra. Recognition of the exstrophy variant is important because the treatment and prognosis are very different.

Robotic Simultaneous Repair of Rectovesical Fistula With Vesicourethral Anastomotic Stricture after Radical Prostatectomy: Step-by-Step Technique and Outcomes.

OBJECTIVE: To report our experience and outcomes using a novel robotic technique for the simultaneous repair of rectovesical fistula (RVF) with vesicourethral anastomotic stricture (VUAS) after radical prostatectomy (RP). METHODS: Between 2019 and 2021, four consecutive patients who underwent robotic-assisted simultaneous repair of RVF with concurrent VUAS after RP were retrospectively reviewed. Baseline characteristics and perioperative outcomes were examined and reported. Complications were graded using the modified Clavien-Dindo classification system and the European Association of Urology Complications Panel Assessment and Recommendations. RESULTS: Four cases with a median age of 68.5 (63.3-72.3) years were treated. Interposition omentum flaps were used in all our cases. One case had perineal urethral mobilization to reach healthy urethral margins and tension-free vesicourethral anastomosis. Surgeries were uneventful, with no intraoperative complications reported. Median operative time, estimated blood loss, and length of hospital stay were 370 (291.3-453) minutes, 255 (175-262.5) mL, and 2.5 (2-3) days, respectively. Median Jackson-Pratt drains, Double-J stents and Foley catheter removal days were 6 (6-10), 38 (32-43), and 30 (27-41) days, respectively. No postoperative complications were reported. The median follow-up time was 16.25 (12-26) months, and no fistula recurrence was shown. CONCLUSION: Robotic-assisted laparoscopic repair could represent an effective approach for the simultaneous repair of RVF with concomitant VUAS. More studies and management standardization are needed to assess the role of the robotic platform in the simultaneous repair of RVF with VUAS after radical prostatectomy.
