Iatrogenic genitourinary fistula: an 18-year retrospective review of 805 injuries

Analysis of the efficacy of modified laparoscopic ureterobladder reimplantation in the treatment of ureterovaginal fistula

OBJECTIVE

Analysis of technical improvements and efficacy of modified laparoscopic ureteral bladder reimplantation for the treatment of ureterovaginal fistula.

METHODS

A retrospective analysis was conducted on clinical data from 20 patients who developed a ureterovaginal fistula due to gynecological surgeries and underwent modified laparoscopic ureteral bladder reimplantation at our hospital from September 2018 to May 2024.

RESULTS

20 patients with ureterovaginal fistula were included, with 9 cases on the left side, 9 on the right side, and 2 bilateral. The locations of the ureterovaginal fistulas were all in the distal ureter. The average age was 50.24 ± 5.22 years, and the average body mass index was 23.22 ± 3.98. The average duration of urine leakage before surgery was 12.20 ± 7.05 days. All surgeries were successful (20/20), with an average operation time of 140.85 ± 55.80 min, intraoperative blood loss of 14.50 ± 7.42 ml, and postoperative hospital stay of 8.24 ± 4.47 days. The ureteral stents were left in place for a mean duration of (51.50 ± 9.65) days postoperatively. No complications occurred after the surgery, and imaging follow-up at 9 months indicated that all patients had recovered well.

CONCLUSION

Early diagnosis and treatment are essential for patients with ureterovaginal fistula. During the modified ureteral bladder reimplantation, it is crucial to ensure tension-free anastomosis without excessive dissection of the distal ureter. Laparoscopic ureteral bladder reimplantation is a reliable, safe, minimally invasive, and well-accepted surgical method, deserving of further promotion.

Endoureteral ablation: A novel technique to occlude the ureter in patients with urinary tract fistulae

Urinary fistulae are abnormal connections between the urinary system and adjacent body parts, often resulting from factors such as infection, radiation, malignancy, protracted labor, gynecologic surgery, and gastrointestinal tract surgery. These fistulae can lead to persistent urinary incontinence, skin breakdown, social humiliation, psychosocial trauma, and severe infections. Current treatments include surgical repair, urinary diversion, and ureteral embolization, though these can have complications and are not always successful or feasible for all patients. This manuscript proposes a novel approach to correcting urinary fistulae: Endoureteral ablation using laser or radiofrequency ablation. These techniques, known for treating various conditions, show promise in causing fibrosis to occlude fistulae. Early success in animal and human models suggests endoureteral ablation as a potentially more effective, less invasive, and cost-effective alternative to current methods, especially for patients unfit for surgery. However, further studies are needed to establish its viability and effectiveness.

The Management of Iatrogenic Ureterovaginal Fistula in a Resource-Limited Setting: A 12-Year Experience at Four Fistula Surgery Centers in Uganda

Background Ureterovaginal fistulae usually follow iatrogenic injury to the ureter during pelvic surgery. This manifests as urine incontinence and results in serious psychosocial effects on women. Ureterovaginal fistulae unlike vesicovaginal fistulae present challenges in diagnosis and management especially in resource-constrained settings. Objective The objective of this study is to describe the magnitude, etiology, diagnosis, management, and outcomes of iatrogenic ureterovaginal fistula in Uganda over a 12-year period. Methods A retrospective review of charts for women who had fistula repair at four fistula repair centers in Uganda from 2010 to 2021 was conducted. The diagnosis of ureterovaginal fistula was made clinically using a history of leakage of urine through the vagina following a pelvic surgery, a negative methylene blue dye test, and a three-swab test. All women were managed using open transvesical ureteral reimplantation with or without a Boari flap. The outcome of surgery was successful fistula repair with urine continence and was determined at two months post-surgery. Results Overall, 477 women were managed for genitourinary fistulae during the study period. Approximately one in every 10 women with genitourinary fistula had an iatrogenic ureterovaginal fistula (n=47, 9.8%). The mean age of women with ureterovaginal fistula was 31.9 (SD: ±11.8) years. The majority of ureterovaginal fistulae (n=33, 70.7%) followed cesarean sections done at general hospitals (n=22, 46.8%) by medical officers (n=32, 68.1%). Clinical assessment was accurate in diagnosing ureterovaginal fistula. Successful fistula repair was achieved in 45 (95.7%) cases. Conclusion Iatrogenic ureterovaginal fistulae are common in Uganda, and most follow cesarean section performed at lower-level health facilities by medical officers. In resource-limited settings where advanced diagnostic techniques are not available or not affordable, simple stepwise clinical evaluation is effective in making a diagnosis. Open ureteral reimplantation with or without a Boari flap has a high successful repair rate.

Iatrogenic Female Genitourinary Fistula in Uganda: Etiology, Twelve-Year Trends, and Risk Factors for Development Following Cesarean Section

Purpose

To describe the magnitude and trend of the iatrogenic genitourinary fistula in Uganda, and the risk factors for development following the Cesarean Section (CS).

Methods

A retrospective review of charts of women with a confirmed diagnosis of genitourinary fistula at four regional fistula repair sites in Uganda between 2010 and 2021 was conducted. A fistula was classified as iatrogenic if it was; ureteric, vesico-cervical, vesico-uterine, or vaginal vault fistula that followed an obstetric or gynecological surgery. The annual proportions for the ischemic and iatrogenic fistula over the study period were compared. A sub group analysis of women with genitourinary fistula delivered by CS was done to determine the factors associated with iatrogenic fistula. Multivariable log binomial regression was performed to determine the independent risk factors.

Results

There were 521 women who presented with genito-urinary fistula of which, 169 (32.4%) were iatrogenic. Most of the iatrogenic fistulae followed CS (71%). The proportions of iatrogenic fistulae increased from 8/52 (9.6%) in 2010 to 38/88 (43.2%) in 2020. The risk factors for iatrogenic fistula following CS were; Grand-multiparity (OR = 5.8; 95% CI: 2.1-15.4), Repeat CS (OR = 4.1; 95% CI: 1.8-9.3), CS performed by an intern doctor (OR = 4.8; 95% CI: 1.5-15.5) and CS done at a Health Centre IV (OR = 4.5; 95% CI: 1.2-16.7).

Conclusion

The magnitude of the iatrogenic genitourinary fistula in Uganda is high and most follow CS. There is an observed rising trend in iatrogenic fistula. The risk factors for iatrogenic fistula following CS are grandmultiparity, repeat CS, CS performed by intern doctors and CS performed at lower health facilities. There is a need for continuous training and supervision of lower cadre doctors involved in CS to reduce on the rising trend of iatrogenic fistula.

The burden of iatrogenic obstetric fistulas in Sub-Saharan Africa: Systematic review and meta-analysis protocol

BACKGROUND

Obstetric fistulas are abnormal open connection(s) between the vagina and the urinary tract or the rectum resulting from tragic injuries sustained by mothers during childbirth that lead to urine and/or faecal incontinence. Due to the rapidly growing middle class in sub-Saharan Africa (SSA) and the corresponding quest for hospital delivery and caesarean section, surgery-related (iatrogenic) obstetric fistulas are on the rise. Worryingly, there is scanty data on surgery-related fistulas. This review aims to collate empirical evidence on the magnitude of iatrogenic obstetric fistulas in SSA, generate country-specific data and explore factors that influence obstetric surgery-related fistulas.

METHODS

All relevant databases, PubMed, LILACS, CINAHL, SCOPUS and Google Scholar will be searched from 1st January 2000 to 31st March 2024 using search terms developed from the major concepts in the title without restrictions by language. The Cochrane Library, African Journals Online, Data Base of African Thesis and Dissertations Including Research (DATAD-R D Space) and preprint repositories will also be searched. Reference lists of relevant studies will be searched and experts in the field will be contacted for additional (unpublished) studies. The search output will be exported to Endnote where duplicate studies will be removed. The deduplicated studies will be exported to Rayyan where study screening and selection will be conducted. At least two authors will independently select studies, extract data and assess quality in the included studies using pretested tools. Disagreements between reviewers will be resolved through discussion. Data analysis will be performed with RevMan 5.4. Comparative binary outcomes will be reported as odds ratio (OR) or risk ratio (RR) and for continuous outcomes, mean difference and standard deviations (SDs) will be used. Non-comparative studies will be analysed as weighted proportions. Heterogeneity between studies will be assessed graphically and statistically, and where a significant level is detected, the random-effects model meta-analysis will be performed. All estimates will be reported with their 95% confidence intervals (CIs). Where data permit, we will conduct subgroup and sensitivity analyses to test the robustness of the estimates on key quality domains. The overall quality of the evidence will be assessed using GRADE (Grading of Recommendations Assessment, Development and Evaluation).

EXPECTED STUDY OUTCOMES

This systematic review and meta-analysis uses rigorous methods and best practices to attempt to collate all empirical evidence and estimate country-specific proportions of iatrogenic (surgery-related) fistulas among obstetric fistula patients across countries in SSA. This review will explore context-specific variables, provide insights into their impact and relate them to the type and experience of personnel performing the obstetric procedures that lead to obstetric fistulas. The findings of the full review are expected to inform the development of national and regional Training Programs for Medical Officers, support the development of a consensus "minimum acceptable standard of care" and inform quality assurance standards for clinicians involved in the provision of surgical obstetric care.

Equivalence between physicians and associate clinicians in the frequency of iatrogenic urogenital fistula following cesarean section in Tanzania and Malawi

BACKGROUND

Physicians and associate (non-physician) clinicians conduct cesarean sections in Tanzania and Malawi. Urogenital fistulas may occur as complications of cesarean section. Location and circumstances can indicate iatrogenic origin as opposed to ischemic injury following prolonged, obstructed labor.

METHODS

This retrospective review assessed the frequency of iatrogenic urogenital fistulas following cesarean sections conducted by either associate clinicians or physicians in Tanzania and Malawi. It focuses on 325 women with iatrogenic fistulas among 1290 women who had fistulas after cesarean birth in Tanzania and Malawi between 1994 and 2017. An equivalence test compared the proportion of iatrogenic fistulas after cesarean sections performed by associate clinicians and physicians (equivalence margin = 0.135). Logistic regression was used to model the occurrence of iatrogenic fistula after cesarean section, controlling for cadre, date, maternal age, previous abdominal surgery and parity.

RESULTS

Associate clinicians attended 1119/1290 (86.7%) cesarean births leading to fistulas, while physicians attended 171/1290 (13.3%). Iatrogenic fistulas occurred in 275/1119 (24.6%) cesarean births by associate clinicians and in 50/171 (29.2%) cesarean births by physicians. The risk difference and 90% confidence interval were entirely contained within an equivalence margin of 13.5%, supporting a conclusion of equivalence between the two cadres. The odds of iatrogenic fistula after cesarean section were not statistically significantly different between associate clinicians and physicians (aOR 0.90; 95% CI 0.61-1.33).

CONCLUSIONS

Associate clinicians appear equivalent to physicians performing cesarean sections in terms of iatrogenic fistula risk. Lower iatrogenic proportions for associate clinicians could reflect different caseloads. The occurrence of iatrogenic fistulas illustrates the importance of appropriate labor management and cesarean section decision-making, irrespective of health provider cadre. Given the noninferior performance and lower costs of employing associate clinicians, other countries with insufficient and/or unequally distributed health workforces could consider task-shifting cesarean sections to associate clinicians.

Rare causes of genital fistula in nine African countries: a retrospective review

BACKGROUND

Most genital fistulas result from prolonged, obstructed labor or surgical complications. Other causes include trauma (from accidents, traditional healers, or sexual violence), radiation, carcinoma, infection, unsafe abortion, and congenital malformation.

METHODS

This retrospective records review focuses on rare fistula causes among 6,787 women who developed fistula after 1980 and sought treatment between 1994 and 2017 in Tanzania, Uganda, Kenya, Malawi, Zambia, Rwanda, Ethiopia, Somalia, and South Sudan. We compare fistula etiologies across countries and assess associations between rare causes and type of incontinence (urine, feces, or both).

RESULTS

Rare fistula accounted for 1.12% (76/6,787) of all fistulas, including traumatic accidents (19/6,787, 0.28%), traumatic sexual violence (15/6,787, 0.22%), traumatic injuries caused by traditional healers (13/6,787, 0.19%), unsafe abortion (10/6,791, 0.15%), radiation (8/6,787, 0.12%), complications of HIV infection (6/6,787, 0.09%), and congenital abnormality (5/6,787, 0.07%). Trauma caused by traditional healers was a particular problem among Somali women.

CONCLUSION

Fistulas attributable to rare causes illuminate a variety of risks confronting women. Fistula repair training materials should distinguish trauma caused by traditional healers as a distinct fistula etiology. Diverse causes of fistula call for multi-pronged strategies to reduce fistula incidence.

Vesico-Vaginal Fistula in Females in 2010-2020: a Systemic Review and Meta-analysis

INTRODUCTION

In the Western world today, urogenital fistula, including vesicovaginal fistula (VVF), is rare. However, while it remains significant in developing parts of the world due to prolonged and obstructed labor, in this study, we systematically reviewed the existing literature, discussing VVF occurrence, its etiology, and outcomes.

MATERIAL AND METHODS

We used electronic databases to search relevant articles from 2010-2020. The screening was performed with the help of Covidence. Relevant data from included studies were extracted in excel sheets, and final analysis was done using CMA-3 using proportion with 95% confidence interval (CI).

RESULTS

Fifteen studies reported the VVF among the fistula series. The pooled result showed 76.57% cases of VVF (CI, 65.42-84.96), out of which 27.54% were trigonal, 55.70% supra-trigonal, and the rest with a varied description like circumferential, juxta-cervical, juxta-urethral. Obstetric etiology was commonly reported with 19.29% (CI, 13.26-27.21) with cesarean section and 31.14% (CI, 18.23-47.86) with obstructed labor. Hysterectomy was the commonly reported etiology among gynecological etiology (46.52%, CI; 36.17-57.19). Among different surgical treatments employed for fistula closure, 49.50% were by abdominal approach (CI, 37.23-61.82), and 42.31% by vaginal approach (CI, 31.82-53.54). Successful closure of fistula was reported in 87.09% of the surgeries (CI, 84.39-89.38).

CONCLUSION

The vesicovaginal fistula is the most common type of genitourinary fistula. Major causes of fistula are gynecological surgery, obstructed labor, and cesarean section. The vaginal approach and abdominal are common modalities of repair of fistula with favorable outcomes in the majority of the patients.

A 6-year retrospective clinical review of iatrogenic ureteric injuries repaired in a resource-deprived setting

Background

Seventy percent of ureteric injuries result from iatrogenic causes with about 75% of these diagnosed in the postoperative period. It may have fatal complications such as sepsis and or renal functional damage increasing morbidity and treatment cost.

Objective

The study aimed to identify the risk factors for iatrogenic ureteric injuries from open surgical procedures and the intervention outcome in a resource-poor setting.

Patients and methods

This was a multi-centre study. The clinical records of patients with iatrogenic ureteric injuries seen between 2015–2021 who were managed at the urology units of the Margaret Marquart Catholic Hospital, and the Ho Teaching Hospital, in the Volta region of Ghana, were retrieved. The data extracted included patients’ demographic factors, the clinical presentation, the primary surgery details, the time from surgery to presentation, the intervention offered, and the outcomes. The data were analysed using the Statistical Package for Social Scientists (SPSS) version 24.0.

Results

Twelve patients aged between 24–54 years with a total of 19 ureteric injuries were managed. The injuries resulted from a hysterectomy in 10 cases (83.3%), and one each from emergency caesarean section and inguinal hernia repair with traction and transection injuries respectively (16.7%). Seven out of 12 cases were diagnosed 48 h after surgery. Bilateral injuries occurred in 7 cases (14/19 injuries). Intraoperative recognition was common in unilateral injuries and surgeries performed by specialist surgeons. Ureteroneocystostomy (14/19), uretero-ureterostomy (1/19), and open suture release were the management procedures performed as in the intervention.

Conclusion

Open hysterectomy (83.7%) was the most common procedure leading to iatrogenic ureteric injuries in this study. Intra-operative recognition occurred when trained specialist surgeons performed the surgery. Late presentation with more severe morbidity was found amongst non-specialist surgeons. Thus, improvement in training to allow intra-operative diagnosis should be encouraged in general practitioners to reduce morbidity and improve outcomes.

A retrospective review of genital fistula occurrence in nine African countries

BACKGROUND

Female genital fistulas are abnormal communications that lead to urinary and/or fecal incontinence. This analysis compares the characteristics of women with fistulas to understand how countries differ from one another in the circumstances of genital fistula development.

METHODS

This retrospective records review evaluated demographics and circumstances of fistula development for 6,787 women who sought fistula treatment between 1994 and 2017 in Tanzania, Uganda, Kenya, Malawi, Rwanda, Somalia, South Sudan, Zambia, and Ethiopia.

RESULTS

Most women developed fistula during childbirth, whether vaginal (3,234/6,787, 47.6%) or by cesarean section (3,262/6,787, 48.1%). Others had fistulas attributable to gynecological surgery (215/6,787, 3.2%) or rare causes (76/6,787, 1.1%). Somalia, South Sudan, and Ethiopia had comparatively high proportions following vaginal birth and birth at home, where access to care was extremely difficult. Fistulas with live births were most common in Kenya, Malawi, Rwanda, Uganda, Tanzania, and Zambia, indicating more easily accessible care.

CONCLUSIONS

Characteristics of women who develop genital fistula point to geographic differences in obstetric care. Access to care remains a clear challenge in South Sudan, Somalia, and Ethiopia. Higher proportions of fistula after cesarean birth and gynecological surgery in Kenya, Malawi, Rwanda, Uganda, Tanzania, and Zambia signal potential progress in obstetric fistula prevention while compelling attention to surgical safety and quality of care.

Iatrogenic genito-urinary fistula following cesarean birth in nine sub-Saharan African countries: a retrospective review

Background

Genito-urinary fistulas may occur as complications of obstetric surgery. Location and circumstances can indicate iatrogenic origin as opposed to pressure necrosis following prolonged, obstructed labor.

Methods

This retrospective review focuses on 787 women with iatrogenic genito-urinary fistulas among 2942 women who developed fistulas after cesarean birth between 1994 and 2017. They are a subset of 5469 women who sought obstetric fistula repair between 1994 and 2017 in Tanzania, Uganda, Kenya, Malawi, Rwanda, Somalia, South Sudan, Zambia, and Ethiopia. We compared genito-urinary fistula classifications following vaginal birth to classifications following cesarean birth. We assessed whether and how the proportion of iatrogenic genito-urinary fistula was changing over time among women with fistula, comparing women with iatrogenic fistulas to women with fistulas attributable to pressure necrosis. We used mixed effects logistic regression to model the rise in iatrogenic fistula among births resulting in fistula and specifically among cesarean births resulting in fistula.

Results

Over one-quarter of women with fistula following cesarean birth (26.8%, 787/2942) had an injury caused by surgery rather than pressure necrosis due to prolonged, obstructed labor. Controlling for age, parity, and previous abdominal surgery, the odds of iatrogenic origin nearly doubled over time among all births resulting in fistula (aOR 1.94; 95% CI 1.48–2.54) and rose by 37% among cesarean births resulting in fistula (aOR 1.37; 95% CI 1.02–1.83). In Kenya and Rwanda the rise of iatrogenic injury outpaced the increasing frequency of cesarean birth.

Conclusions

Despite the strong association between obstetric fistula and prolonged, obstructed labor, more than a quarter of women with fistula after cesarean birth had injuries due to surgical complications rather than pressure necrosis. Risks of iatrogenic fistula during cesarean birth reinforce the importance of appropriate labor management and cesarean decision-making. Rising numbers of iatrogenic fistulas signal a quality crisis in emergency obstetric care. Unaddressed, the impact of this problem will grow as cesarean births become more common.

Factors associated with surgical repair success of female genital fistula in the Democratic Republic of Congo: Experiences of the Fistula Care Plus Project, 2017-2019

Objective

We sought to document outcomes and factors associated with surgical success in hospitals supported by the Fistula Care Plus Project in the Democratic Republic of Congo (DRC), 2017–2019.

Methods

This was a retrospective cohort study analysing routine repair data on women with Female Genital Fistula. Univariate and multivariate analyses were conducted to determine factors associated with successful fistula repair.

Results

A total of 895 women were included in this study, with a mean age of 34 years (±13 years). The majority were married or in union (57.4%) and living in rural areas (82.0%), while nearly half were farmers (45.9%). The average duration living with fistula was 8 years (±7). Vesicovaginal (70.5%) and complex (59.8%) fistulas were the most common fistula types. Caesarean section (34.7%), obstructed labour (27.0%) and prolonged labour (23.0%) were the main aetiologies, with the causal deliveries resulting in stillbirth in 88% of cases. The vaginal route (74.9%) was the primary route for surgical repair. The median duration of bladder catheterization after surgery was 14 days (interquartile range [IQR] 7–21). Multivariate analysis revealed that Waaldijk type I fistula (adjusted odds ratio [aOR]:2.71, 95% confidence interval [CI]:1.36–5.40), no previous surgery (aOR:2.63, 95% CI:1.43–3.19), repair at Panzi Hospital (aOR: 2.71, 95% CI:1.36–5.40), and bladder catheterization for less than 10 days (aOR:13.94, 95% CI: 4.91–39.55) or 11–14 days (aOR: 6.07, 95% CI: 2.21–15.31) were associated with better repair outcomes.

Conclusion

The Fistula Care Plus Project in the DRC recorded good fistula repair outcomes. However, further efforts are needed to promote adequate management of fistula cases.

Factors associated with marital status of women with genital fistula after childbirth: a retrospective review in nine African countries

OBJECTIVE

To examine characteristics associated with remaining married with fistula.

DESIGN

Retrospective record review and logistic regression.

SETTING

Tanzania, Uganda, Kenya, Malawi, Zambia, Rwanda, Ethiopia, Somalia and South Sudan.

PARTICIPANTS

Women who developed fistula during childbirth (1975-2017) and sought treatment (1994-2017).

OUTCOME MEASURE

Self-reported status of living with original husband at time of presentation for fistula repair.

RESULTS

Over half of the women lived with their husbands at the time of fistula treatment (57.2%, 3375/5903). The strongest predictor of remaining married with fistula was either parity at fistula development (adjusted odds ratio [AOR] 1.4-4.4) or living kids at fistula repair (among women who had not given birth between fistula development and repair) (AOR 1.7-4.9). Predicted probability of remaining married declined sharply over the first 2 years of incontinence, levelling out thereafter. Predicted probability of remaining married was lower for women with both urinary and faecal incontinence (AOR 0.68) as compared with women with urinary incontinence alone. Probability of remaining married with fistula declined over time (AOR 1.03-0.57). The woman's education was not a statistically significant predictor, but the odds of remaining married were 26% higher if the husband had any formal schooling.

CONCLUSION

Most husbands do not abandon wives with fistula following childbirth. Treatment, counselling, social support and rehabilitation must consider the circumstances of each woman, engaging men as partners where appropriate. Communities and facilities offering fistula repair services should stress the importance of early intervention.

Childbirth-Associated Fistula and Perineal Tears Repaired on Outreach Campaigns in Remote Democratic Republic of Congo

Purpose

To describe the demographics and evaluate the repair of childbirth-associated injuries leading to incontinence in patients in remote Democratic Republic of Congo (DRC).

Patients and Methods

Four surgical outreach campaigns were organised between March 2018 and October 2019. These campaigns specifically targeted women with incontinence secondary to childbirth-associated injuries. Patients were recruited on a voluntary basis, and locations included Katako-kombe (Sankuru province), Wamba (Haut Uelé province), Karawa (North Ubangi province) and Kipaka (Maniema province). Necessary care was provided along with informal teaching with local healthcare professionals.

Results

A total of 481 patients,14–71 years old with a mean of 32 years of age, were included in this study. The average duration of incontinence associated with a childbirth injury was 6.8 years. Vesicovaginal fistulas (277/481; 57.6%) and perineal tears (148/481; 30.8%) were predominant, while the combination of vesicovaginal and rectovaginal fistulas were seen in only 5 (1.0%) patients. Vaginal delivery (259/481; 53.9%), caesarean section (120/481; 25.0%) and laparotomy (hysterectomy) (102/481; 21.2%) were identified as the causes of the fistulas treated during the surgical campaign. Vesicovaginal fistulas were more likely to require complex repairs, as compared to rectovaginal fistulas and perineal tears (P-value <0.0001). As well, vesicovaginal fistulas were less likely to result in successful resolution of the incontinence when compared to rectovaginal fistulas and perineal tears (P-value < 0.0001).

Conclusion

Vesicovaginal fistulas are predominant among childbirth injuries encountered in remote DRC with poorly managed vaginal deliveries being the leading cause. Cure rate of fistulas and perineal tears is high during outreach campaigns; however, long-term follow-up is limited. There remains a need to train and mentor rural medical professionals in the DRC on adequate management of obstetric emergencies.

Vesico-vaginal fistula in Tunisia: Epidemiology and risk factors of treatment failure

INTRODUCTION

Vesico-vaginal fistula (VVF) is a global healthcare problem that has a high prevalence in developing countries. The aim of this work is to study the epidemiological, clinical and therapeutic characteristics of VVF post-obstetric and gynecologic procedures in order to identify the predictive factors of surgical treatment failure.

METHODS

Data were collected from 132 VVF patients in our institution between 1985 and 2017. VVF was classified according to Zmerli's classification. Patients underwent surgical treatment and were evaluated after a follow-up period of 6 months. Successful treatment was defined as the absence of urine leakage whereas recurrence was defined as the presence of urine leakage immediately after the surgery or after a period of dryness with a confirmed VVF. Risk factors of surgical treatment failure were identified.

RESULTS

The average age of patients was 44 years. The patients were multiparous in 62% of cases. VVF was consecutive to hysterectomy in 62.1% of cases, and after childbirth in 34%. VVF was retro-trigonal in 99 cases (75%) and trigonal in 33 cases (25%). The average size of the fistula was 1cm (0.3-2cm). VVF repair was performed by vaginal approach in 68% of cases and abdominal approach in 32% of cases. Treatment failure was noted in 36 patients (27%). Predictive factors of treatment failure were: vaginal fibrosis (P<0.001); trigonal location of the fistula (P<0.001); large diameter of the VVF>1cm (P<0.001); and complex and complicated fistulas (P=0.02).

CONCLUSION

Although Tunisia is a developing country, the main cause of VVF was not obstetrical. Treatment failure, noted in almost one third of cases, was, in our series, correlated with the quality of the vaginal tissue, the size and the location of the fistula, and its complexity.

Vesicouterine Fistula: A Robotic Approach

INTRODUCTION AND HYPOTHESIS

This video demonstrates surgical repair of a vesicouterine fistula via a robotic, uterine-sparing approach.

METHODS

In this video, we present a vesicouterine fistula, which occurred after cesarean delivery. The patient presented with cyclical hematuria 4 years following delivery. She underwent uterine-conserving robotic repair via excision of the fistula tract through an intentional cystotomy. The uterus and bladder were closed in multiple layers.

RESULTS

The patient tolerated the procedure well, and CT cystogram 6 weeks following surgery demonstrated no concern for defect or recurrent fistulization. The patient was asymptomatic 9 months following her procedure.

CONCLUSION

Repair of a vesicouterine fistula may be safely completed via a minimally invasive approach without need for routine hysterectomy.

Toward a complete estimate of physical and psychosocial morbidity from prolonged obstructed labour: a modelling study based on clinician survey

Introduction

Prolonged obstructed labour often results from lack of access to timely obstetrical care and affects millions of women. Current burden of disease estimates do not include all the physical and psychosocial sequelae from prolonged obstructed labour. This study aimed to estimate the prevalence of the full spectrum of maternal and newborn comorbidities, and create a more comprehensive burden of disease model.

Methods

This is a cross-sectional survey of clinicians and epidemiological modelling of the burden of disease. A survey to estimate prevalence of prolonged obstructed labour comorbidities was developed for prevalence estimates of 27 comorbidities across seven categories associated with prolonged obstructed labour. The survey was electronically distributed to clinicians caring for women who have suffered from prolonged obstructed labour in Asia and Africa. Prevalence estimates of the sequelae were used to calculate years lost to disability for reproductive age women (15 to 49 years) in 54 low- and middle-income countries that report any prevalence of obstetric fistula.

Results

Prevalence estimates were obtained from 132 participants. The median prevalence of reported sequelae within each category were: fistula (6.67% to 23.98%), pelvic floor (6.53% to 8.60%), genitourinary (5.74% to 9.57%), musculoskeletal (6.04% to 11.28%), infectious/inflammatory (5.33% to 9.62%), psychological (7.25% to 24.10%), neonatal (13.63% to 66.41%) and social (38.54% to 59.88%). The expanded methodology calculated a burden of morbidity associated with prolonged obstructed labour among women of reproductive age (15 to 49 years old) in 2017 that is 38% more than the previous estimates.

Conclusions

This analysis provides estimates on the prevalence of physical and psychosocial consequences of prolonged obstructed labour. Our study suggests that the burden of disease resulting from prolonged obstructed labour is currently underestimated. Notably, women who suffer from prolonged obstructed labour have a high prevalence of psychosocial sequelae but these are often not included in burden of disease estimates. In addition to preventative and public health measures, high quality surgical and anaesthesia care are urgently needed to prevent prolonged obstructed labour and its sequelae.

Contemporary Issues in Obstetric Fistula

We discuss a variety of contemporary issues relating to obstetric fistula. These include definitions of these injuries, the etiologic mechanisms by which fistulas occur, the role of specialist fistula centers in diagnosis and management, the classification of fistulas, and the assessment of surgical outcomes. We also review the growing need for complex reconstructive surgical procedures, follow-up challenges, and the transition to a fistula-free world in which other pathologies (such as pelvic organ prolapse) will be of increasing importance. Finally, we discuss the need to develop responsive systems of maternal health care that treat women with competence, compassion, respect, and fairness.

Evaluation and management of obstetric genital fistulas treated at a pelvic floor centre in Germany

BACKGROUND

Obstetric genital fistulas are an uncommon condition in developed countries. We evaluated their causes and management in women treated at a German pelvic floor centre.

METHODS

Women who had undergone surgery for obstetric genital fistulas between January 2006 and June 2020 were identified, and their records were reviewed retrospectively.

RESULTS

Eleven out of 40 women presented with genitourinary fistulas, and 29 suffered from rectovaginal fistulas. In our cohort, genitourinary fistulas were more common in multiparous women (9/11), and rectovaginal fistulas were more common in primiparous women (24/29). The majority of the genitourinary fistulas were at a high anterior position in the vagina, and all rectovaginal fistulas were at a low posterior position. While all genitourinary fistulas were successfully closed, rectovaginal fistula closure was achieved in 88.65% of cases. Women who suffered from rectovaginal fistulas and were at high risk of recurrence or postoperative functional discomfort and desired another child, we recommended fistula repair in the context of a subsequent delivery. For the first time, pregnancy-related changes in the vaginal wall were used to optimize the success rate of fistula closure.

CONCLUSIONS

In developed countries, birth itself can lead to injury-related genital fistulas. As fistula repair lacks evidence-based guidance, management must be tailored to the underlying pathology and the surgeon's experience. Attention should be directed towards preventive obstetric practice and adequate perinatal and postpartum care. Although vesicovaginal fistulas occur rarely, in case of urinary incontinence after delivery, attention should be paid to the patient, and a vesicovaginal fistula should be ruled out.

Characteristics of Obstetric and Iatrogenic Urogenital Fistulas in Burkina Faso: A Cross-Sectional Study

Objective

To compare the sociodemographic, clinical, and therapeutic characteristics of obstetric urogenital fistulas (OF) and iatrogenic urogenital fistulas (IF) treated in seven centers in Burkina Faso. Material and Methods. We carried out a cross-sectional study over a seven years' period (January 1, 2010 to December 31, 2016). We considered as iatrogenic all urogenital fistulas (UGF) occurred after elective caesarean section, gynecologic surgery (hysterectomy, myomectomy, and prolapse repair), or induced abortion. UGF following vaginal delivery after prolonged labor without obstetric maneuvers or caesarean section were considered as obstetric. UGF caused by other mechanisms (emergency caesarian section, congenital, and traumatic) were excluded from this study. The statistical analysis was carried out using version 14 of the STATA software. A logistic regression model was used to compare the two groups.

Results

310 cases of UGF were included. IF accounted for 25.8% (n = 80) versus 74.2% (n = 230) for OF. The median age was 35 years for IF and 35.38 years for OF. The vesicovaginal fistulas were predominant (74.5%) in the two groups. All circumferential fistulas were found in the OF group. OF were frequently associated with residence in rural areas (OR = 1.8; CI = [1.05–3.1]), low level of education (OR = 5.4; CI = [2.3–12.9]), and a height under 158 cm (OR = 3.4 CI = [1.7–6.6]). Vaginal sclerosis was less common among IF (OR = 2.2; CI = [1–4.6]). The failure of surgical treatment after 3 months was more associated with OF (OR = 4.7; CI = [1.1–20.5]).

Conclusion

OF were the most common, frequently affecting short women living in rural area and with low level of schooling. Fistulas were also more severe in the OF group. IF gave better results after surgical repair.

Obstetric vesico-vaginal fistulas: Midvaginal and juxtacervical fistula repair outcomes in the Democratic Republic of Congo

OBJECTIVE

This study aims to establish the postoperative success rates of midvaginal versus juxtacervical obstetric vesicovaginal fistula (VVF) repairs. In addition, we aim to quantify the impact of patient sociodemographic variables, fistula classification, and surgical repair techniques associated with postoperative outcomes.

METHODS

A retrospective cohort study was conducted involving 420 women who had undergone a primary obstetric VVF repair. All data were collected from the Panzi Hospital, Democratic Republic of Congo between 2015 and 2017. Patient notes were analyzed to determine sociodemographic variables, symptoms, fistula classification, surgical repair techniques, and postoperative follow up. Binary logistic regression presented as χ² for trend was used to establish P values.

RESULTS

Overall, 95.6% and 96.2% of midvaginal and juxtacervical VVF, respectively, underwent a successful repair. The principal prognostic factor associated with a statistically significant likelihood of a successful repair was the degree of fibrosis noted preoperatively (P =0.004, 95% confidence interval [CI] 2.38-94.61). Furthermore, VVF were more likely to have a successful repair if they were closed in two layers (P = 0.004, 95% CI 1.86-25.81) and sutured vertically (P = 0.005, 95% CI 1.16-2.52).

CONCLUSION

Overall, high postoperative success rates of obstetric VVF repair can be expected among well-trained surgeons but a complex interplay of factors means that the ability to preoperatively foreshadow individual outcomes remains difficult.

Management of Genitourinary Fistulas Following Benign Gynecological and Obstetric Procedures: A Single Surgeon Experience

Background:

Genitourinary fistula results in lot of anxiety in the suffering females. Scant literature regarding the comprehensive management of genitourinary fistula i.e. VVF and UVF is available.

Objective:

The aim of the study was to review a single surgeon experience in dealing with these complex situations.

Material and Methods:

We conducted a retrospective, institutional review board approved chart review of patients who underwent genitourinary fistula repair from Jan 2014 till Dec 2019. Of all the fistulas VVF accounted for 18 and UVF for 12 cases. Pre-operative diagnosis in these patients was based predominantly on the history, local examination and cystoscopy. Of the 18 VVF 12 were managed laparoscopically and 6 by open O'Connor's repair. Of the 12 UVF, 8 were managed laparoscopically and 4 by open ureteric reimplants. All were followed up for three months post operatively.

Results:

A total of 30 patients were treated since 2014 till December 2019. Average age for the VVF was 54.72 ≤ 10.9 years and that for UVF repair was 59.9 ≤ 7.6 years. Hysterectomies for benign diseases accounted for 66.66% of VVF and 91.6% of UVF. Of the VVF patients one required a ureteric reimplantation, remaining were managed with O'Connors' repair. We had one failure which was successfully repaired after 6 weeks. None of our patients with UVF repairs had a failure at three months follow-up.

Conclusion:

Genitourinary fistulas are a debilitating problem in females but a comprehensive approach regarding diagnosis and treatment can cure these patients.

Predictors of Urinary Retention After Vesicovaginal Fistula Surgery: A Retrospective Case-Control Study

OBJECTIVE

The objective of this study is to determine the predictors for urinary retention after vesicovaginal fistula surgery.

METHODS

This was a retrospective case-control study of women who underwent vesicovaginal fistula repair between January 2014 and December 2017 at the Fistula Care Centre in Lilongwe, Malawi. Cases were defined as patients with documented urinary retention, defined as a postvoid residual that is 50% greater than the total void of at least 100 mL. The cases and controls were matched by the 3 components of the Goh classification system in a ratio of 1:5. Univariate analysis was used to detect differences between demographic, clinical characteristics, and operative techniques between cases and control. Logistic regression analysis was performed for estimation of odds ratios (ORs).

RESULTS

There were no statistically significant differences between the 40 cases and 187 controls, when comparing age, gravidity, parity, body mass index, and length of postoperative catheterization. The median amount of postvoid residual noted at the time of diagnosis was 240 mL (range, 55-927 mL). Odds for urinary retention was 3 times higher among those with vertical closure than patients with horizontal closure of the bladder (OR, 2.91; 95% confidence interval, 1.35-6.20). Patients with prior fistula repairs were significantly less likely to develop urinary retention compared to those receiving surgery for the first time (OR, 0.27; 95% confidence interval, 0.10-0.67).

CONCLUSIONS

Vertical closure of the bladder and patients without a history of prior fistula repairs are predictors for developing urinary retention after fistula repair surgery.

Urethrovaginal fistula repair with or without concurrent fascial sling placement: A retrospective review

INTRODUCTION

We sought to review outcomes of urethrovaginal fistula (UVF) repair, with or without concurrent fascial sling placement.

METHODS

All patients diagnosed with UVF at our center from 1988-2017 were included in this study. Patient charts were reviewed from a prospectively kept fistula database, and patient characteristics and surgical outcomes were described. Descriptive statistics were applied to compare complication rates between patients with or without fascial sling placement at the time of UVF repair.

RESULTS

A total of 41 cases of UVF were identified, all of which underwent surgical repair. Median age at diagnosis was 49 years (interquartile range [IQR] 35-62). All patients had undergone pelvic surgery. UVF etiology was secondary to stress urinary incontinence (SUI) surgery in 17 patients (41%) and urethral diverticulum repair in seven patients (17%). The most common presenting symptom was continuous incontinence in 19 patients (46%). Nineteen patients had a fascial sling placed at the time of surgery (46%), with no significant difference in complication rates (26% vs. 23%, p=0.79). Two patients had Clavien-Dindo grade I complications (5%) and one had a grade III complication (2%). Four patients had long-term complications (10%), including urinary retention, chronic pain, and urethral stricture. Two patients had UVF recurrence (5%). Median followup after surgery was 21 months (IQR 4-72).

CONCLUSIONS

UVF should be suspected in patients with continuous incontinence following a surgical procedure. Most UVF surgical repairs are successful and can be done with concurrent placement of a fascial sling.

Characteristics of Genitourinary Fistula in Kigali, Rwanda; 5-Year Trends

OBJECTIVE

To assess the characteristics of women presenting with genitourinary fistula over a 5-year period in Kigali, Rwanda. Genitourinary (GU) fistula is a devastating condition that can result from difficult vaginal deliveries or as a surgical complication. Rwanda has seen notable increases in cesarean section rates as a result of a successful universal health care system. It is unclear how the increase in cesarean section rates may influence the types of fistula diagnosed.

MATERIALS AND METHODS

A cross-sectional study was conducted of women presenting for evaluation to the International Organization for Women and Development in Kigali, Rwanda, between February 1, 2013 and October 31, 2017. Data were collected from medical records, including demographics, surgical history, physical exam findings, and surgical intervention.

RESULTS

Two thousand ninety-one women presented for evaluation during the study period, of these 630 (30%) were diagnosed with GU fistula. Of the fistula diagnosed, 392 (62%) were vesicovaginal fistula, 185 (29%) were vesicouterine or vesicocervical, and 56 (9%) were ureterovaginal fistula. The percent of GU fistula that involved the ureter, uterus, and/or cervix significantly increased over the time period: 29.6% in 2013, 34.6% in 2014; 43.0% in 2015, 42.9% in 2016, and 45.3% in 2017.

CONCLUSION

There was a significant increase in the proportion of vesicouterine, vesicocervical, and ureterovaginal fistula presenting in Rwanda over the 5-year period, with the majority occurring after cesarean section.

Nigeria, a high burden state of obstetric fistula: a contextual analysis of key drivers

Obstetric fistula (OF) remain a source of public health concern and one of the most devastating maternal morbidities afflicting about two million women, mostly in developing countries. It is still prevalent in Nigeria due to the existence of socio-cultural beliefs/practices, socio-economic state and poor health facilities. The country's estimated annual 40,000 pregnancy-related deaths account for about 14% of the global maternal mortality, placing it among the top 10 most dangerous countries in the world for a woman to give birth. However, maternal morbidities including OF account for 20 to 30 times the number of maternal mortalities. This review substantiates why OF is yet to be eliminated in Nigeria as one of the countries with the largest burden of obstetric fistula. There is need for coordinated response to prevent and eliminate this morbidity via political commitment, implementation of evidence-based policy and execution of prevention programs.

Frequency and management of non-obstetric fistula in the Democratic Republic of Congo: experience from the Fistula Care Plus project

Objective

To describe the frequency, causes and post‐repair outcomes of NOF in hospitals supported by the Fistula Care Plus (FC+) project in the Democratic Republic of Congo.

Methods

Retrospective cohort study from 1 January 2015 to 31 December 2017 in three FC + supported fistula repair sites.

Results

Of 1984 women treated for female genital fistula between 2015 and 2017 in the three FC + supported hospitals, 384 (19%) were considered to be non‐obstetric fistula (NOF) cases. 49.3% were married/in a relationship at the time of treatment vs. 69% before the fistula, P < 0.001. Type III (n = 247; 64.3%) and type I (n = 121; 31.5%) fistulas according to Kees/Waaldijk classification were the most common. The main causes of NOF were medical procedure (n = 305; 79.4%); of these, caesarean section (n = 234; 76.7%) and hysterectomy (n = 54; 17.7%) were the most common. At hospital discharge, the fistula was closed and dry in 353 women (95.7%).

Conclusion

Non‐obstetric fistula, particularly due to iatrogenic causes, was relatively common in the DRC, calling for more prevention that includes improved quality of care in maternal health services.

Rising trends in iatrogenic urogenital fistula: A new challenge

Objective

To analyze trends in iatrogenic urogenital fistula among patients admitted for fistula repair at the Pakistan Institute of Medical Sciences, Islamabad.

Methods

In this longitudinal study, all patients who presented for fistula repair between 2006 and 2018 were included in the study. Patient data were collected on age, parity, and type and etiology of fistula, which was classified as ischemic or iatrogenic.

Results

Of 634 fistula patients, 371 (58.5%) had iatrogenic fistula, while 263 (41.5%) patients developed ischemic fistula due to obstructed labor. Mean age of patients was 31.6 years. Yearly trends showed an increase in iatrogenic fistula from 43.2% in 2006–2008 to 71.4% in 2017–2018. The major etiological contributor to iatrogenic fistula was hysterectomy (52.5%), followed by cesarean hysterectomy (26.4%), and cesarean delivery (19.9%).

Conclusion

A rising trend in iatrogenic fistula was observed. This emphasizes the need for optimization of surgical approaches and surgical skills. Moreover, gynecologic surgeries should be restricted to authorized gynecologic surgeons.

A rising yearly trend in iatrogenic fistula was observed over a 12‐year period in Pakistan.

Baseline renal function and renal ultrasound findings in patients with obstetric fistulas (RENFRU): a prospective cohort study

OBJECTIVE

To describe and compare baseline renal anatomy and renal function in patients with obstetric fistulas, and to evaluate whether preoperative renal testing and imaging may aid with operative decision making.

DESIGN

A prospective cohort study.

SETTING

Fistula Care Centre in Malawi.

POPULATION

Women with an obstetric fistula.

METHODS

Baseline creatinine testing and renal ultrasounds were performed. Surgeons completed a short questionnaire on the usefulness of creatinine and renal ultrasound on operative decision making.

MAIN OUTCOME MEASURES

Baseline creatinine and renal ultrasound findings.

RESULTS

Four surgeons performed operations on 85 patients. The mean creatinine in patients with vesicovaginal fistulas (VVF) was 0.60 ng/ml versus patients with uretero-vaginal fistulas (UVF) (0.79 ng/ml, P = 0.012). When a grade 3 or more hydronephrosis is absent on renal ultrasound, the negative predictive value of the presence of UVF is 93.3% (95% confidence interval [CI] 88.6-96.2) with a specificity of 97.2% (95% CI 90.3-99.6). In cases of UVF, surgeons found the renal ultrasound results useful or very useful 87.5% of the time, and the creatinine useful or very useful 75% of the time.

CONCLUSION

In this pilot study, most patients with obstetric fistulas presented with a normal creatinine. In the absence of a grade 3 hydronephrosis or above on renal ultrasound, the probability of not having a UVF is 93.3%. Surgeons should consider performing preoperative renal ultrasound testing in all patients with an obstetric fistula, particularly in women with a prior laparotomy, as this population has risk factors for ureterovaginal fistula.

TWEETABLE ABSTRACT

Most patients with obstetric fistulas have normal renal function. Preoperative renal ultrasounds should be performed.

Delivery mode for prolonged, obstructed labour resulting in obstetric fistula: a retrospective review of 4396 women in East and Central Africa

OBJECTIVE

To evaluate the mode of delivery and stillbirth rates over time among women with obstetric fistula.

DESIGN

Retrospective record review.

SETTING

Tanzania, Uganda, Kenya, Malawi, Rwanda, Somalia, South Sudan, Zambia and Ethiopia.

POPULATION

A total of 4396 women presenting with obstetric fistulas for repair who delivered previously in facilities between 1990 and 2014.

METHODS

Retrospective review of trends and associations between mode of delivery and stillbirth, focusing on caesarean section (CS), assisted vaginal deliveries and spontaneous vaginal deliveries.

MAIN OUTCOME MEASURES

Mode of delivery, stillbirth.

RESULTS

Out of 4396 women with fistula, 3695 (84.1%) delivered a stillborn baby. Among mothers with fistula giving birth to a stillborn baby, the CS rate (overall 54.8%, 2027/3695) rose from 45% (162/361) in 1990-94 to 64% (331/514) in 2010-14. This increase occurred at the expense of assisted vaginal delivery (overall 18.3%, 676/3695), which declined from 32% (115/361) to 6% (31/514).

CONCLUSIONS

In Eastern and Central Africa, CS is increasingly performed on women with obstructed labour whose babies have already died in utero. Contrary to international recommendations, alternatives such as vacuum extraction, forceps and destructive delivery are decreasingly used. Unless uterine rupture is suspected, CS should be avoided in obstructed labour with intrauterine fetal death to avoid complications related to CS scars in subsequent pregnancies. Increasingly, women with obstetric fistula add a history of unnecessary CS to their already grim experiences of prolonged, obstructed labour and stillbirth.

TWEETABLE ABSTRACT

Caesarean section is increasingly performed in African women with stillbirth treated for obstetric fistula.

Rehabilitation and reintegration programming adjunct to female genital fistula surgery: A systematic scoping review

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.

Removing barriers to fistula care: Applying appreciative inquiry to improve access to screening and treatment in Nigeria and Uganda

A research-to-action collaboration sought to understand and respond to barriers to female genital fistula treatment in Nigeria and Uganda. This was guided by appreciative inquiry, a participatory approach for transformative programing with four phases: (1) inquire, (2) imagine, (3) innovate, and (4) implement. Through this process, partners designed and refined a treatment barrier reduction intervention using multiple communication channels to disseminate a consistent fistula screening algorithm and provide transportation vouchers to those screening positive. Partnership between an implementation organization, a research institution, and local community partners enabled data-driven design and patient-centered implementation to address specific barriers experienced by women.

Women's recommendations: vacuum extraction or caesarean section for prolonged second stage of labour, a prospective cohort study in Uganda

Objectives

To investigate what women who have experienced vacuum extraction or second stage caesarean section (CS) would recommend as mode of birth in case of prolonged second stage of labour.

Methods

A prospective cohort study was conducted in a tertiary referral hospital in Uganda. Between November 2014 and July 2015, women with a term singleton in vertex presentation who had undergone vacuum extraction or second stage CS were included. The first day and 6 months after birth women were asked what they would recommend to a friend: vacuum extraction or CS and why. Outcome measures were: proportions of women choosing vacuum extraction vs. CS and reasons for choosing this mode of birth.

Results

The first day after birth, 293/318 (92.1%) women who had undergone vacuum extraction and 176/409 (43.0%) women who had undergone CS recommended vacuum extraction. Of women who had given birth by CS in a previous pregnancy and had vacuum extraction this time, 31/32 (96.9%) recommended vacuum extraction. Six months after birth findings were comparable. Less pain, shorter recovery period, avoiding surgery and the presumed relative safety of vacuum extraction to the mother were the main reasons for preferring vacuum extraction. Main reasons to opt for CS were having experienced CS without problems, CS presumed as being safer for the neonate, CS being the only option the woman was aware of, as well as the concern that vacuum extraction would fail.

Conclusions

Most women would recommend vacuum extraction over CS in case of prolonged second stage of labour.

Our Experience with Iatrogenic Ureteric Injuries among Women Presenting to University College Hospital, Ibadan: A Call to Action on Trigger Factors

Background

Ureteric injuries leading to ureterovaginal fistula (UVF) is less common than vesicovaginal fistula, as a cause of urinary incontinence. Recently, there is a surge in the number of UVF cases presenting to University College Hospital (UCH) following a caesarean delivery. The urogynaecology unit at UCH is at the forefront of providing surgical repair for women with all forms of genitourinary fistulas. We describe our experience with managing UVF arising from ureteric injury.

Methods

A retrospective data collection of UVF cases managed from January 2012–December 2017 at UCH is presented. Information on sociodemographic and obstetric characteristics, presenting complaints, antecedent surgery, treatment received, findings at surgery, and postoperative complications were obtained with a structured proforma.

Results

Eighteen cases of UVFs due to iatrogenic ureteric injury were managed. Majority (N=11; 61.1%) of the women suffered the injury following the emergency caesarean section (EMCS). Abdominal hysterectomy operation accounted for four (22.2%) cases, and one case each (5.6%) was due to vaginal hysterectomy and destructive operations. Prolonged obstructed labour (POL) (81.8%) was the most common indication for the EMCS, while 18.2% had surgery on account of lower uterine segment fibroid. Most of the ureteric injuries were on the left side. Postoperative complications documented were haemorrhage, urinary tract infection, wound infection, and injury to the neighbouring structure.

Conclusion

Caesarean section being one of the most performed surgical operations in Nigeria was surprisingly found to be the most common cause of ureteric injury ahead of hysterectomy. It is a pointer that the surgeons might not have properly learnt the art of the caesarean delivery well. We recommend adequate surgical training of medical officers/surgeons that are involved.

Transvaginal Retropubic Urethropexy Versus Pubovaginal Sling for Treatment of Postrepair Urinary Incontinence

OBJECTIVES

The aim of this study was to compare the success rates of transvaginal retropubic urethropexy with fascia lata pubovaginal sling (PV sling) for treatment of postrepair urinary incontinence at a fistula center in Nigeria.

METHODS

This was a retrospective review of 60 patients who had transvaginal retropubic urethropexy and 46 patients who had PV sling on account of postrepair incontinence at National Obstetric Fistula Centre, Abakaliki, Nigeria, between January 2014 and December 2016. Data were retrieved from the hospital records. Success was defined as negative urinary stress test at 3 months after repair. Data were analyzed with SPSS version 20, and P value <0.05 was taken as statistically significant. χ was used to determine the association between the procedures and success rate.

RESULTS

The success rate of transvaginal retropubic urethropexy versus PV sling was 53.3% versus 82.6% (χ = 9.95, P = 0.02). Complications occurred in 13.2%.

CONCLUSIONS

In conclusion, the efficacy of the fascia lata PV sling was more than that of transvaginal retropubic urethropexy for postrepair urinary incontinence. Urodynamic assessments need to be incorporated into management of these women for better patient's selection for each procedure.

Trajectories of women's physical and psychosocial health following obstetric fistula repair in Uganda: a longitudinal study

OBJECTIVES

To explore trajectories of physical and psychosocial health, and their interrelationship, among women completing fistula repair in Uganda for 1 year post-surgery.

METHODS

We recruited a 60-woman longitudinal cohort at surgical hospitalisation from Mulago Hospital in Kampala Uganda (Dec 2014-June 2015) and followed them for 1 year. We collected survey data on physical and psychosocial health at surgery and at 3, 6, 9 and 12 months via mobile phone. Fistula characteristics were abstracted from medical records. All participants provided written informed consent. We present univariate analysis and linear regression results.

RESULTS

Across post-surgical follow-up, most women reported improvements in physical and psychosocial health, largely within the first 6 months. By 12 months, urinary incontinence had declined from 98% to 33% and general weakness from 33% to 17%, while excellent to good general health rose from 0% to 60%. Reintegration, self-esteem and quality of life all increased through 6 months and remained stable thereafter. Reported stigma reduced, yet some negative self-perception remained at 12 months (mean 17.8). Psychosocial health was significantly impacted by the report of physical symptoms; at 12 months, physical symptoms were associated with a 21.9 lower mean reintegration score (95% CI -30.1, -12.4).

CONCLUSIONS

Our longitudinal cohort experienced dramatic improvements in physical and psychosocial health after surgery. Continuing fistula-related symptoms and the substantial differences in psychosocial health by physical symptoms support additional intervention to support women's recovery or more targeted psychosocial support and reintegration services to ensure that those coping with physical or psychosocial challenges are appropriately supported.

Caesarean section provision and readiness in Tanzania: analysis of cross-sectional surveys of women and health facilities over time

OBJECTIVES

To describe trends in caesarean sections and facilities performing caesareans over time in Tanzania and examine the readiness of such facilities in terms of infrastructure, equipment and staffing.

DESIGN

Nationally representative, repeated cross-sectional surveys of women and health facilities.

SETTING

Tanzania.

PARTICIPANTS

Women of reproductive age and health facility staff.

MAIN OUTCOME MEASURES

Population-based caesarean rate, absolute annual number of caesareans, percentage of facilities reporting to perform caesareans and three readiness indicators for safe caesarean care: availability of consistent electricity, 24 hour schedule for caesarean and anaesthesia providers, and availability of all general anaesthesia equipment.

RESULTS

The caesarean rate in Tanzania increased threefold from 2% in 1996 to 6% in 2015-16, while the total number of births increased by 60%. As a result, the absolute number of caesareans increased almost fivefold to 120 000 caesareans per year. The main mechanism sustaining the increase in caesareans was the doubling of median caesarean volume among public hospitals, from 17 caesareans per month in 2006 to 35 in 2014-15. The number of facilities performing caesareans increased only modestly over the same period. Less than half (43%) of caesareans in Tanzania in 2014-15 were performed in facilities meeting the three readiness indicators. Consistent electricity was widely available, and 24 hour schedules for caesarean and (less systematically) anaesthesia providers were observed in most facilities; however, the availability of all general anaesthesia equipment was the least commonly reported indicator, present in only 44% of all facilities (34% of public hospitals).

CONCLUSIONS

Given the rising trend in numbers of caesareans, urgent improvements in the availability of general anaesthesia equipment and trained anaesthesia staff should be made to ensure the safety of caesareans. Initial efforts should focus on improving anaesthesia provision in public and faith-based organisation hospitals, which together perform more than 90% of all caesareans in Tanzania.

Causes and management of urogenital fistulas. A retrospective cohort study from a tertiary referral center in Saudi Arabia

Objectives:

To review the etiology and management of urogenital fistulas at a tertiary care referral center.

Methods:

We retrospectively identified all patients with urogenital fistula referred to the King Fahad Medical City, Riyadh, Saudi Arabia, between January 2005 and July 2016 from electronic records. We collected data on age, parity, etiology and type of fistula, radiologic findings, management, and outcome.

Results:

Of the 32 patients with urogenital fistula identified, 17 (53.1%) had vesicovaginal fistula. The mean parity was 5.9 (0-15). Obstetric surgery was the most common etiology, accounting for 22 fistulas (68.8%). Twenty of these (90.9%) were complications of cesarean delivery, of which 16 (80%) were repeat cesarean delivery. Forty surgical repair procedures were performed: 20 (50%) via an abdominal approach, 11 (27.5%) via a vaginal approach, 7 (17.5) via a robotic approach, and 2 (5%) using cystoscopic fulguratizon. The primary surgical repair was successful in 23 patients (74%), the second repair in 5 (16.1%), and the third repair in one (3.1%). One fistula was cured after bladder catheterization, and 2 patients are awaiting their third repair.

Conclusion:

Unlike the etiology of urogenital fistulas in other countries, most fistulas referred to our unit followed repeat cesarean delivery: none were caused by obstructed labor, and only a few occurred after hysterectomy. Most patients were cured after the primary surgical repair.

Colorectal-Vaginal Fistulas: Imaging and Novel Interventional Treatment Modalities

Colovaginal and/or rectovaginal fistulas cause significant and distressing symptoms, including vaginitis, passage of flatus/feces through the vagina, and painful skin excoriation. These fistulas can be a challenging condition to treat. Although most fistulas can be treated with surgical repair, for those patients who are not operative candidates, limited options remain. As minimally-invasive interventional techniques have evolved, the possibility of fistula occlusion has enriched the therapeutic armamentarium for the treatment of these complex patients. In order to offer optimal treatment options to these patients, it is important to understand the imaging and anatomical features which may appropriately guide the surgeon and/or interventional radiologist during pre-procedural planning.

Too Long to Wait: Obstetric Fistula and the Sociopolitical Dynamics of the Fourth Delay in Soroti, Uganda

Uganda has one of the highest obstetric fistula rates in the world with approximately 200,000 women currently suffering. Surgical closure successfully treats fistula in the majority of cases, yet there is a severe shortage of facilities and trained surgeons in low-resource countries. The purpose of this study was to examine Ugandan women's experiences of obstetric fistula with the aim of adding narrative depth to the clinical literature on this devastating birth injury. Data were collected through semistructured interviews, focus groups, and participant observation. Resulting narratives were consensus coded, and key themes were member-checked using reciprocal ethnography. Women who suffered from fistula described barriers in accessing essential obstetric care during labor-barriers that are consistent with the three delays framework developed by Thaddeus and Maine. In this article, we extend this scholarship to discuss a fourth, critical delay experienced by fistula survivors-the delay in the diagnosis and treatment of their birth injury.

The association between female genital fistula symptoms and gender-based violence: A multicountry secondary analysis of household survey data

OBJECTIVE

The Demographic and Health Surveys (DHS), which include standardised questions on female genital fistula symptoms, provide a unique opportunity to evaluate the epidemiology of fistula. This study sought to examine associations between self-reported fistula symptoms and experience of gender-based violence (GBV) among women interviewed in DHS surveys.

METHODS

This study used data from thirteen DHS surveys with standardised fistula and domestic violence modules. Data from the most recent survey in each country were pooled, weighting each survey equally. Multivariable logistic regressions controlled for maternal and demographic factors.

RESULTS

Prevalence of fistula symptoms in this sample of 95 625 women ranges from 0.3% to 1.8% by country. The majority of women reporting fistula symptoms (56%) have ever experienced physical violence, and more than one-quarter have ever experienced sexual violence (27%), compared with 38% and 13% among women with no symptoms, respectively. Similarly, 16% of women with fistula symptoms report recently experiencing sexual violence-twice the percentage among women not reporting symptoms (8%). Women whose first experience of sexual violence was from a non-partner have almost four times the odds of reporting fistula symptoms compared with women who never experienced sexual violence. These associations indicate a need to investigate temporal and causal relationships between violence and fistula.

CONCLUSIONS

The increased risk of physical and sexual violence among women with fistula symptoms suggests that fistula programmes should incorporate GBV into provider training and services.

Obstetric fistulae in southern Mozambique: incidence, obstetric characteristics and treatment

BACKGROUND

Obstetric fistula is one of the most devastating consequences of unmet needs in obstetric services. Systematic reviews suggest that the pooled incidence of fistulae in community-based studies is 0.09 per 1000 recently pregnant women; however, as facility delivery is increasing, for the most part, in Africa, incidence of fistula should decrease. Few population-based studies on fistulae have been undertaken in Sub-Saharan Africa, including Mozambique. This study aimed to estimate the incidence of obstetric fistulae in recently delivered mothers, and to describe the clinical characteristics and care, as well as the outcome, after surgical repair.

METHODS

We selected women who had delivered up to 12 months before the start of the study (June, 1st 2016). They were part of a cohort of women of reproductive age (12-49 years), recruited from selected clusters in rural areas of Maputo and Gaza provinces, Southern Mozambique, who were participating in an intervention trial (the Community Level Interventions for Pre-eclampsia trial or CLIP trial). Case identification was completed by self-reported constant urine leakage and was confirmed by clinical assessment. Women who had confirmed obstetric fistulae were referred for surgical repair. Data were entered into a REDCap database and analysed using R software.

RESULTS

Five women with obstetric fistulae were detected among 4358 interviewed, giving an incidence of 1.1 per 1000 recently pregnant women (95% CI 2.16-0.14). All but one had Caesarean section and all of the babies died. Four were stillborn, and one died very soon after birth. All of the patients identified and reached the primary health facility in reasonable time. Delays occurred in the care: in diagnosis of obstructed labour, and in the decision to refer to the secondary or third-level hospital. All but one of the women were referred to surgical repair and the fistulae successfully closed.

CONCLUSION

This population-based study reports a high incidence of obstetric fistulae in an area with high numbers of facility births. Few first and second delays in reaching care, but many third delays in receiving care, were identified. This raises concerns for quality of care.

Diagnosis and management of 365 ureteric injuries following obstetric and gynecologic surgery in resource-limited settings

Introduction

Ureteric injuries are among the most serious complications of pelvic surgery. The incidence in low-resource settings is not well documented.

Methods

This retrospective review analyzes a cohort of 365 ureteric injuries with ureterovaginal fistulas in 353 women following obstetric and gynecologic operations in 11 countries in Africa and Asia, all low-resource settings. The patients with ureteric injury were stratified into three groups according to the initial surgery: (a) obstetric operations, (b) gynecologic operations, and (c) vesicovaginal fistula (VVF) repairs.

Results

The 365 ureteric injuries in this series comprise 246 (67.4%) after obstetric procedures, 65 (17.8%) after gynecologic procedures, and 54 (14.8%) after repair of obstetric fistulas. Demographic characteristics show clear differences between women with iatrogenic injuries and women with obstetric fistulas. The study describes abdominal ureter reimplantation and other treatment procedures. Overall surgical results were good: 92.9% of women were cured (326/351), 5.4% were healed with some residual incontinence (19/351), and six failed (1.7%).

Conclusions

Ureteric injuries after obstetric and gynecologic operations are not uncommon. Unlike in high-resource contexts, in low-resource settings obstetric procedures are most often associated with urogenital fistula. Despite resource limitations, diagnosis and treatment of ureteric injuries is possible, with good success rates. Training must emphasize optimal surgical techniques and different approaches to assisted vaginal delivery.

Management of vesicovaginal fistulas after gynecologic surgery

Objective:

In developed nations, surgery, especially gynecologic procedures, is the major cause of vesicovaginal fistulas (VVFs). We retrospectively evaluated our treatment modalities for VVF repair caused by a gynecologic surgery, and discussed the reasons of selecting certain surgical techniques and their outcomes.

Materials and Methods:

We compared the surgical procedure preferences of surgeons and their results with patient and surgeon characteristics for the management of VVFs after an inciting gynecologic surgery in Süleyman Demirel University Hospital, Isparta over a 10-year period. The surgical procedures were undertaken in departments of urology and obstetrics and gynecology.

Results:

Abdominal repair was chosen for 65%, vaginal repair for 25%, and laparoscopic repair for 10% of patients. For the 75% of the patients that urologists operated, they chose the abdominal route. The mean parity number of patients who underwent abdominal repair was lower than that for vaginal repairs (p<0.05). For the patients managed with the vaginal route, 20% had a Martius flap, and 80% had a simple excision and repair. For patients operated via the abdominal route, 18% needed omental flap; no tissue interposition was used for the rest. The mean hospitalization time was less in patients managed with transvaginal repair (3.4 days) compared with transabdominal repair (9.2 days) (p<0.05).

Conclusion:

The choice of repair method depends on surgeon’s training (gynecology vs. urology). The vaginal route should be the first choice because it does not compromise the success rate and the mean hospitalization time is less. For the transvaginal approach, access to the lesion is the most important factor for the success of the procedure. No flap is needed for tissues that appear well vascularized.

Genital tract fistula: a case series from a tertiary centre in South Africa

INTRODUCTION AND HYPOTHESIS

We describe the demographic profile, aetiology, management and surgical outcomes in women with genital tract fistula presenting to a tertiary urogynaecology unit.

METHODS

This retrospective audit included 87 patients managed in our unit between 2008 and 2015. Frequencies and means with standard deviations are presented for categorical and continuous data. Continuous dependent variables are categorized as above or below the median for bivariate analyses performed using the chi-squared test (α = 0.05).

RESULTS

The mean age of the women was 34.7 years, 64.4% were Black African, 70.2% were multiparous, 49.4% were married, 82.8% were employed, and 21.8% were HIV-infected, with 47.4% on antiretroviral treatment. Vesicovaginal (47.1%) and rectovaginal (41.4%) fistula were the most frequent injuries. The majority of the injuries (67.8%) were obstetric, with 26.4% occurring during caesarean delivery. Repair had been attempted previously in 43.7% of patients. In 63.2% of the repairs the approach was vaginal and in 35.6% abdominal. Interposition grafts were used in 23% of repairs. In 85.1% of patients the initial repair at our centre was successful. Patients with multiple repairs were more likely to have complications (p = 0.03). HIV infection was not significantly associated with complications.

CONCLUSIONS

A high rate of successful repair was found, with previous unsuccessful repairs associated with poorer outcomes, highlighting the need for centralized management.

Presentation and management of vesicovaginal fistulae after delivery at a German women's hospital

Vesicovaginal fistulae are rarely seen after childbirth in developed countries. This article deals with the causes, presentation, and management of obstetric vesicovaginal fistulae in patients treated at a German women's hospital.

Vesicouterine fistula: teaching video on diagnosis and surgical treatment

INTRODUCTION

A 42-year-old woman presented with urinary incontinence 9 years after the last of four vaginal deliveries. She had also had one Caesarean section. Immediately after the last delivery, she presented with haematuria, which resolved within a few hours, but the drain remained prophylactically for 7 days. Nine years later, she was referred to a specialist hospital.

METHOD

The patient presented with continuous urinary incontinence, and physical examination revealed a loss of urine from the vagina, the latter confirmed by a methylene blue test showing loss of urine from the uterine cervix. Other diagnostic techniques used were cystography, cystoscopy and uro-CT. Based on a literature review of the management options for such patients and the relevant clinical details of our patient, a decision was made to perform a total abdominal hysterectomy and fistula repair.

RESULTS AND DISCUSSION

Six months following surgery, the results were entirely satisfactory, with full urinary continence and significant improvement in the patient's quality of life. A discussion about controversial approaches to diagnosis and management is included.
