INTRODUCTION
Colovesical fistulas (CVFs) account for approximately 95% enterovesical fistulas (EVFs). About 2/3 CVF cases are diverticular in origin. It mainly presents with urological signs such as pneumaturia and fecaluria. Diagnostic investigations aim at confirming the presence of a fistula. Although conservative management can be chosen for selected individuals, most patients are mainly treated through surgical interventions. CVF represents a challenging condition, which records high rates of morbidity and mortality. Our systematic review aimed at achieving deeper knowledge of both indications, in addition to short- and long-term outcomes related to CVF management.
EVIDENCE ACQUISITION
We performed a systematic literature review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) guidelines. Pubmed/MEDLINE, Embase, Scopus, Cochrane Library and Web of Science databases were used to search all related literature.
EVIDENCE SYNTHESIS
The 22 included articles covered an approximately 37 years-study period (1982-2019), with a total 1365 patient population. CVF etiology was colonic diverticulitis in most cases (87.9%). Pneumaturia (50.1%), fecaluria (40.9%) and urinary tract infections (46.6%) were the most common symptoms. Abdomen computed tomography (CT) scan (80.5%), colonoscopy (74.5%) and cystoscopy (55.9%) were the most frequently performed diagnostic methods. Most CVF patients underwent surgery (97.1%) with open approach (63.3%). Almost all patients had colorectal resection with primary anastomosis with or without ostomy and 53.2% patients underwent primary repair or partial/total cystectomy. Four percent anastomotic leak, 1.8% bladder leak and 3.1% reoperations rates were identified. In an average 5-68-month follow-up, overall morbidity, overall mortality and recurrences rates recorded were 8-49%, 0-63% and 1.2%, respectively.
CONCLUSIONS
CVF mainly affects males and has diverticular origin in almost all cases. Pneumaturia, fecaluria and urinary tract infections are the most characteristic symptoms. Endoscopic tests and imaging are critical tools for diagnostic completion. Management of CVFs depends on the underlying disease. Surgical treatment represents the final approach and consists of resection and reanastomosis of offending intestinal segment, with or without bladder closure. In many cases, a single-stage surgical strategy is selected. Perioperative and long-term outcomes prove good.

Review
: To conduct a systematic review of the literature on vesicovaginal fistula (VVF), including reporting on the aetiology, in both developed and underdeveloped countries; diagnosis; intraoperative prevention; and management. : We conducted a systematic review of the literature on VVF through the PubMed and the Cochrane Library according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The search was conducted from 1985 to 2018 in English, using the keywords 'fistula' and 'vesicovaginal fistula'. Prospective studies were preferred; however, retrospective studies and case reports were used when no prospective studies were available. All authors' extracted relevant data related to the proposed review of VVF and carefully examined collected articles. : In all, 116 relevant articles were identified and 43 articles were included in this systematic review. The outcome of surgical reconstruction was >90%, but the outcome may be suboptimal in radiotherapy (RT)-induced VVFs. Absolute indications for an abdominal approach included: ureteric involvement, the need for concomitant bladder augmentation, severe vaginal stenosis, and an inability to tolerate the dorsal lithotomy position (e.g. due to muscular spasticity). Typically, it was recommended to wait at least 3 months to allow the inflammatory response to subside before definitive surgery. Early fistula repair can be performed in the absence of infection and in patients who have not received pelvic RT. : VVF is rare in developed countries. Surgical treatment is the primary method of repair. The outcome of surgical reconstruction exceeds 90%, but the outcome may be suboptimal in RT-induced VVFs. PRISMA: Preferred Reporting Items for Systematic Reviews and Meta-Analyses; RT: radiotherapy; (S)UI: (stress) urinary incontinence; UVF: ureterovaginal fistula; VVF: vesicovaginal fistula.

Meta-Analysis Review
BACKGROUND
Obstetric fistula is a severe condition which has devastating consequences for a woman's life. The estimation of the burden of fistula at the population level has been impaired by the rarity of diagnosis and the lack of rigorous studies. This study was conducted to determine the prevalence and incidence of fistula in low and middle income countries.
METHODS
Six databases were searched, involving two separate searches: one on fistula specifically and one on broader maternal and reproductive morbidities. Studies including estimates of incidence and prevalence of fistula at the population level were included. We conducted meta-analyses of prevalence of fistula among women of reproductive age and the incidence of fistula among recently pregnant women.
RESULTS
Nineteen studies were included in this review. The pooled prevalence in population-based studies was 0.29 (95% CI 0.00, 1.07) fistula per 1000 women of reproductive age in all regions. Separated by region we found 1.57 (95% CI 1.16, 2.06) in sub Saharan Africa and South Asia, 1.60 (95% CI 1.16, 2.10) per 1000 women of reproductive age in sub Saharan Africa and 1.20 (95% CI 0.10, 3.54) per 1000 in South Asia. The pooled incidence was 0.09 (95% CI 0.01, 0.25) per 1000 recently pregnant women.
CONCLUSIONS
Our study is the most comprehensive study of the burden of fistula to date. Our findings suggest that the prevalence of fistula is lower than previously reported. The low burden of fistula should not detract from their public health importance, however, given the preventability of the condition, and the devastating consequences of fistula.

Meta-Analysis
BACKGROUND
Entero-colovesical fistula is a rare complication of various benign and malignant diseases. The diagnosis is prominently based on clinical symptoms; imaging studies are necessary not only to confirm the presence of the fistula, but more importantly to demonstrate the extent and the nature of the fistula. There is still a lack of consensus regarding the if, when and how to repair the fistula. The aim of the study is to review the different surgical treatment options, focus on surgical indications, and explore cumulative recurrence, morbidity, and mortality rates of entero-vesical and colo-vesical fistula patients.
METHODS
A systematic review of the literature was conducted according to PRISMA guidelines. Random effects meta-analyses of proportions were developed to assess primary and secondary endpoints. I statistic and Cochran's Q test were computed to assess inter-studies' heterogeneity.
RESULTS
Twenty-two studies were included in the analysis with a total of 861 patients. Meta-analyses of proportions pointed out 5, 22.2, and 4.9% rates for recurrence, complications, and mortality respectively. A single-stage procedure was performed in 75.5% of the cases, whereas a multi-stage operation in 15.5% of patients. Palliative surgery was performed in 6.2% of the cases. In 2.3% of the cases, the surgical procedure was not specified. Simple and advanced repair of the bladder was performed in 84.3% and 15.6% of the cases respectively.
CONCLUSIONS
Although burdened by a non-negligible rate of complications, surgical repair of entero-colovesical fistula leads to excellent results in terms of primary healing. Our review offers opportunities for significant further research in this field. Level of Evidence Level III according to ELIS (SR/MA with up to two negative criteria).

BACKGROUND
Female genital fistula is associated with significant physical, psychological, and economic consequences; however, a knowledge and practice gap exists around services adjunct to fistula surgery.
OBJECTIVES
To examine rehabilitation and reintegration services provided adjunct to genital fistula surgery, map existing programming and outcomes, and identify areas for additional research.
SEARCH STRATEGY
We searched the published and grey literature from January 2000 to June 2019. Two reviewers screened articles and extracted data using standardized methods.
SELECTION CRITERIA
Research and programmatic articles describing service provision in addition to female genital fistula surgery were included.
DATA COLLECTION AND ANALYSIS
Of 3047 published articles and 2623 unpublished documents identified, 26 and 55, respectively, were analyzed.
MAIN RESULTS
Programming identified included combinations of health education, physical therapy, social support, psychosocial counseling, and economic empowerment, largely in sub-Saharan Africa. Improvements were noted in physical and psychosocial health.
CONCLUSIONS
Existing literature supports holistic fistula care through adjunct reintegration programming. Improving the evidence base requires implementing robust study designs, increasing reporting detail, and standardizing outcomes across studies. Increased financing for holistic fistula care is critical for developing and supporting programming to ensure positive outcomes.

Review
Cervical cerclages are associated with improved live birth rates and have low short- and long-term risks. However, there have been reports of fistula formation or erosion of cerclage into the surrounding tissue. Those complications are uncommon and yet are serious. The risk factors associated with its development are still unclear. The purpose of our study was to evaluate the incidence of fistula formation or erosion following transvaginal cervical cerclage and the associated clinical and sociodemographic factors. We conducted a systematic search of PubMed, Medline, and Embase databases to retrieve articles related to transvaginal or transabdominal cervical cerclage. Databases were searched up to July 2021. The study protocol was registered (PROSPERO ID 243542). A total of 82 articles were identified describing cervical cerclage and erosion or fistula formation. A total of 9 full-text articles were included. There were seven case reports and series that described 11 patients who experienced late complications following cervical cerclage. Many of the cerclage procedures were done electively (66.7%). The most common type of cerclage was McDonald (80%). While all cases reported fistula formation, the main location was vesicovaginal fistulas (63.6%). One patient (9.1%) had erosion of their cerclage and another (9.1%) had bladder calculi. Of 75 patients who underwent cerclage in two retrospective case reviews, the overall incidence of fistula was 1.3% and abscess was also 1.3%. Although rare, the most common long-term complication of cervical cerclage placement is fistula formation, particularly vesicovaginal fistulas.

BACKGROUND
This study is aimed to describe our institutional experience and review the literature to date on prostatosymphyseal fistula (PSF), or puboprostatic fistula, following bladder outlet procedures such as transurethral resection of the prostate (TURP) or laser photoselective vaporization of the prostate (PVP).
MATERIALS AND METHODS
We retrospectively queried our institutional experience for management of PSF following PVP performed for symptomatic benign prostatic hyperplasia. We also performed a systematic literature review for PSF following PVP or TURP. Finally, we describe our surgical approach to the management of this challenging condition.
RESULTS
We identified 7 cases of PSF following PVP from our institution, as well as an additional 7 cases following PVP and 9 cases following TURP from literature review. The diagnosis of PSF was made between 0.5 and 24 months following PVP, and the most specific symptoms were pubic pain and difficulty ambulating. Most patients requiring several evaluations before the diagnosis was made using appropriate imaging studies. Seventy percent of patients required surgical intervention including fistula repair or prostatectomy. Our surgical approach has evolved, and we now routinely perform robotic fistula repair with Y-V plasty and interposition flap with excellent results.
CONCLUSIONS
Puboprostatic fistula is a rare and poorly described complication of PVP or TURP. To the best of our knowledge, this case series of PSF following PVP represents the largest series to date and doubles the number of reported cases in the literature. Robotic fistula repair with interposition of either peritoneal or perivesical fat flaps appears to be a viable management strategy.

Meta-Analysis
BACKGROUND
Obstructed labor is one of the five major causes of maternal mortality and morbidity in developing countries. In Ethiopia, it accounts for 19.1% of maternal death. The current review aimed to assess maternal and perinatal outcomes of obstructed labor in Ethiopia.
METHODS
Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed for this systematic review and meta-analysis. A literature search was made using PubMed/MEDLINE, CINAHL, Summon country-specific search, and Cochrane Libraries' online databases. Search terms were adverse outcome, obstructed labor, maternal outcome, fetal outcome, and Ethiopia. The Newcastle-Ottawa scale (NOS), based on a star scoring system, was used to assess the quality of the included studies. The meta-analysis was conducted using STATA 16 software. The pooled prevalence of an adverse maternal outcome, fetal outcome, and association between adverse outcome and obstructed labor was calculated using a random-effects model. Egger's test and funnel plot were used to evaluate publication bias.
RESULT
Eighty-seven studies were included in this review, with an overall sample size of 104259 women and 4952 newborns. The pooled incidence of maternal death was estimated to be 14.4% [14.14 (6.91-21.37). The pooled prevalence of uterine rupture and maternal near-miss was 41.18% (95% CI: 19.83, 62.54) and 30.5% [30.5 (11.40, 49.59) respectively. Other complications such as postpartum hemorrhage, sepsis, obstetric fistula, hysterectomy, bladder injury, cesarean section, and labor abnormalities were also reported. The pooled prevalence of perinatal death was 26.4% (26.4 (95% CI 15.18, 37.7). In addition, the association of obstructed labor with stillbirth, perinatal asphyxia, and meconium-stained amniotic fluid was also demonstrated.
CONCLUSIONS
In Ethiopia, the incidence of perinatal and maternal mortality among pregnant women with obstructed labor was high. The rate of maternal death and maternal near miss reported in this review was higher than incidences reported from high-income and most low and middle-income countries. Uterine rupture, postpartum hemorrhage, sepsis, fistula, hysterectomy, and bladder injury were also commonly reported. To improve the health outcomes of obstructed labor, it is recommended to address the three delay models: enhancing communities' health-seeking behavior, enhancing transportation for an obstetric emergency with different stakeholders, and strengthening the capacity of health facilities to handle obstetric emergencies.

Meta-Analysis
BACKGROUND
Each year, between 50,000 and 100,000 women worldwide develop obstetric fistulae. Approximately 2 million girls across Asia and Africa are estimated to be affected by this condition. However, there is no reliable data on its prevalence in South-East Asia region (SEAR).
OBJECTIVES
The objective of this study is to systematically review and synthesize the data on the prevalence and management of obstetric fistula in SEAR.
METHODS
We searched for the literature that described the prevalence and management practices of obstetric fistula in SEAR. We followed the PRISMA guidelines to select the articles for the review. The quality and relevance were assessed by two reviewers independently using the SIGN checklist. A total of five articles and reports were selected for the review. To review the management practices, we found 63 original studies that were included in the review.
RESULTS
We found five community-based studies estimating the prevalence of obstetric fistula in SEAR; 3 studies were from India, one from Bangladesh and one from Nepal. The pooled prevalence according to self-reports was 1.11 (3 studies including 671,133 participants, 95% confidence interval [CI] 1.09, 1.14) per 100 women. The pooled prevalence of obstetric fistula based on the clinical examination was 0.10 (3 studies involving 4547 participants, 95% CI 0.01, 0.20) per 100 women. The value was close to the pooled estimate based on the smaller studies.
CONCLUSION
More studies are needed to estimate reliable community-based prevalence data and also need to develop evidence-based management guidelines.

BACKGROUND
Arterioureteral fistula (AUF) is a rare, life-threatening condition wherein communication occurs between a ureter and the common, internal, or external iliac artery. The sensitivity of common clinical imaging examination for AUF is low, which leads to a delayed diagnosis and increased mortality. In addition, the increased use of ureteral stents contributes to the growing frequency of AUF.
CASE PRESENTATION
Our two patients were 74 and 65 years old males respectively. They both had a medical history of bladder cancer and underwent radical cystectomy with ureterocutaneostomy. The patients underwent routine catheter exchange during over 1 year postradical cystectomy and subsequently experienced intermittent gross pulsatile haematuria. After a series of imaging examinations failed to identify the cause, the patients were ultimately diagnosed with AUF and treated with interventional radiotherapy, followed by broad-spectrum antibiotics. Positive effects were found.
CONCLUSIONS
The incidence of AUF is increased with the prolongation of survival in patients with related risk factors. This case report aims to highlight early diagnosis and management of AUF to lower the mortality.
