Percutaneous tibial nerve stimulation for the overactive bladder: A single-arm trial.

AIMS: We hypothesise that PTNS is a safe and effective treatment for OAB. Overactive bladder (OAB) is estimated to affect 11.8% of women worldwide, causing diminished quality of life. Lifestyle modifications, muscarinic receptor antagonist and beta-adrenoreceptor agonist remain the mainstay of treatment but are limited by their efficacy and adverse effects. Access to third-line therapies of intravesical botulinum toxin type A or sacral neuromodulation is limited by their invasive nature. Percutaneous tibial nerve stimulation (PTNS) has emerged as a non-invasive treatment option for OAB. METHODS: This study was a single-arm trial of women requesting third-line treatment for OAB. The primary treatment outcome was patient-reported visual analogue score (VAS) improvement of at least 50%. Secondary outcome measures were Urinary Distress Inventory Short Form (UDI-6) score and two-day bladder diary. Patients also provided feedback on adverse effects encountered. RESULTS: In the 84 women recruited, initial treatment protocol showed a success rate of 77.2% among those who completed treatment based on VAS, with a statistically significant improvement in mean UDI-6 score of 20.13 (P < 0.01, standard deviation: 12.52). Continued success following tapering protocol of 60.8% and a mean maintenance protocol of 14.2 months was achieved. No adverse effects were reported. CONCLUSION: The results from this study are in concordance with previously published literature on the effectiveness and safety of PTNS as a treatment modality for OAB. Further randomised controlled trials to evaluate the optimal treatment protocol are warranted to establish a standardised regime.

Sacrospinous fixation: Review of relevant anatomy and surgical technique.

Apical support is an important component of pelvic floor reconstruction for pelvic organ prolapse. Sacrospinous ligament fixation is a recognized procedure for apical support. Complications from sacrospinous ligament fixation include pain (buttock and leg) and bleeding. There is some debate as to the optimal location for placement of the sacrospinous fixation sutures. This review summarizes the neuroanatomy of the coccygeus sacrospinous ligament as it pertains to the sacrospinous ligament fixation procedure. An appreciation of the neuroanatomy will lead to a better understanding of methods to reduce operative complications and improve suture placement. This paper also describes a technique for the sacrospinous fixation procedure to better assist clinicians in dissecting the connective tissue off the ligament. Removing or clearing the connective tissue off the ligament will allow critical landmarks to be easily palpated and hence a more accurate placement of sutures. This in turn may reduce the risk of perioperative complications.

Interventions for treating obstetric fistula: An evidence gap map.

Obstetric fistula is prevalent in low- and middle-income countries, with between 50,000 and 100,000 new cases each year. The World Health Organization aims to eradicate it by 2030 but a clear idea of the extant evidence is unavailable. This evidence map compiled evidence on treatments for obstetric fistula to identify potential knowledge gaps. The protocol for this work was published on the Open Science Framework (DOI: 10.17605/OSF.IO/H7J35). A survey was developed, piloted and distributed online through organisations with an interest in obstetric fistula and snowballing. Results informed the evidence map framework. Searches were run on MEDLINE, Embase, CENTRAL, Global Index Medicus and ScanMedicine on 16 February 2022 to identify potentially eligible systematic reviews, randomised controlled trials, cohort studies and case-control studies. Forward and backward citation chaining was undertaken on relevant systematic reviews and included studies. Studies were screened, coded and assessed for risk of bias by a single reviewer, with a second checking a proportion. The evidence map results were compared to survey results. Thirty-nine people responded to the survey, half of which were clinicians. Of 9796 records identified, 37 reports of 28 studies were included in the evidence map. Many included studies were at some risk of bias; for observational studies, this was predominantly due to lack of controlling for confounders. Most studies (71%) assessed surgical interventions alone. Reporting on other intervention types was limited. Regarding outcome measures most important to survey respondents, 24 studies reported on cure/improvement in obstetric fistula and 20 on cure/improvement in urinary incontinence. Reporting on quality of life, faecal incontinence and sexual function was limited. There is currently little robust evidence to guide patients and practitioners on the most effective treatment option for obstetric fistula. Further research is required to address evidence gaps identified.

The effect of transvaginal prolapse surgery on anorectal function

Objective: Pelvic floor dysfunction can manifest as a spectrum including anorectal dysfunction, vaginal prolapse, and urinary incontinence. Sacrospinous fixation is a procedure performed by gynecologists to treat vaginal prolapse. The present study aims to evaluate the impact of transvaginal prolapse surgery on anorectal function. Materials and Methods: We conducted a retrospective review of patients undergoing sacrospinous fixation surgery for vaginal prolapse between 2014 to 2020. Those with anorectal dysfunction who had also been evaluated by the colorectal service preoperatively and postoperatively were included for analysis. These patients were assessed with symptom-specific validated questionnaires. The effect of surgery on constipation and fecal incontinence symptoms was analyzed. Results: A total of 22 patients were included for analysis. All patients underwent transvaginal sacrospinous fixation, and 95.4% also had posterior colporrhaphy for vaginal prolapse. There were a statistically significant improvements in the Fecal Incontinence Severity Index (FISI), the St. Mark's Incontinence Score (Vaizey), the embarrassment and lifestyle components of the Fecal Incontinence Quality of Life Score, the Constipation Scoring System, the Obstructed Defecation Score, and components of the Patient Assessment of Constipation Quality of Life score. Conclusion: Transvaginal prolapse surgery leads to a favorable effect on anorectal function, with improvements in both obstructed defecation and fecal incontinence scores in this small series. (AU)

A retrospective case series on transvaginal repair of rectovaginal fistula performed by a urogynaecology operative team in Australia.

BACKGROUND: Rectovaginal fistula (RVF) is an abnormal epithelialised connection between the rectum and vagina. It is a common condition in limited resource settings and is caused almost exclusively by obstetric injury. In contrast, RVF is uncommonly seen in high resource settings. AIMS: This study aims to review the aetiology and effectiveness of RVF management in the high resource setting, identifying predictors for repair success and long-term outcomes. MATERIALS AND METHODS: A retrospective case series study of patients who underwent transvaginal RVF repairs at two secondary healthcare facilities over a 14-year period by one operative group. RESULTS: A total of 41 patients underwent 46 surgical repairs. All patients presented with flatal and/or faecal incontinence and aetiology was identifiable in 78.0% (n = 32). Obstetric cause was implicated in 26.8% (n = 11) and other causes include 26.8% (n = 11) from vaginal and abdominal surgery, 14.6% (n = 6) from perianal abscess, 7.32% (n = 3) as complications of Crohn's disease and 2.44% (n = 1) as a complication of a cube pessary. Fistula was cured in 38 of 41 cases (92.7%) with a primary repair closure rate of 80.5% (n = 33). Post-operative symptoms were limited to flatal incontinence in 4.88% (n = 2), faecal incontinence in 2.44% (n = 1), and persistent perineal pain in 7.32% (n = 3). The success of the surgical repair was not significantly impacted by fistula size, aetiology, presence of a stoma for diversion, history of prior repair, duration since RVF formation or repair technique. CONCLUSIONS: This review identifies aetiology for RVF in the high resource setting and highlights the role of earlier surgical repair to minimise patient morbidity with good success in closure and reduction of post-operative symptoms.

The Vertical Rectus Abdominis Myocutaneous Flap to Manage Vaginal Evisceration.

BACKGROUND: Pelvic organ prolapse (POP) is a significant issue requiring surgical correction in 19% of the female population by age 85 years. Complications of POP, especially in women who have undergone hysterectomy, include vaginal evisceration-a serious complication that carries high morbidity and mortality rates. Rarely, vaginal evisceration occurs after colpocleisis. CASE: A 69-year-old female with recurrent vaginal evisceration following colpocleisis underwent surgical repair using a vertical rectus abdominis myocutaneous (VRAM) flap. CONCLUSION: Recurrent cases of POP and vaginal evisceration that are refractory to conventional treatment require consideration of novel management options. To our knowledge, this is the first case using a VRAM flap for the management of vaginal evisceration.

Surgical repair and follow-up of chronic 4th degree obstetric perineal tear (total perineal defect) in 2 centres in eastern Africa.

INTRODUCTION AND HYPOTHESIS: Fourth-degree perineal tear occurs in up to 0.2% of vaginal deliveries. In limited resource communities, women often deliver in local villages without facilities to repair obstetric anal sphincter injuries. These fourth-degree tears heal by secondary intention and result in total perineal defects. The aim of the study is to present medium-term follow-up of a large number of women following repair of chronic fourth-degree tear. METHODS: Repairs of chronic obstetric fourth-degree tears were undertaken during surgical camps at Kagando Hospital, Uganda and Selian Hospital, Tanzania, from December 2013 to October 2019. Women completed Cleveland Clinic Incontinence Scores (CCIS) on admission (face to face) and during the 7-year follow-up period (via telephone). RESULTS: Two hundred fourteen women had medical history and CCIS completed on admission. The mean age at presentation was 33.9 years and mean duration of the condition was 8.9 years. Over a third of women stated they suffered social abandonment because of the unrepaired fourth-degree tear. Nearly 45% of women suffered the tear during the first vaginal delivery. At 1-year follow-up, 87% of 101 women scored 0 (perfect continence) and 94% of 66 women had perfect continence at 2 years. Forty-one births occurred during the follow-up period (32 vaginal deliveries) with two recurrences of fourth-degree tear. CONCLUSIONS: Follow-up in limited resource communities is challenging. Short- to medium-term results of women who had repair of total perineal defect (unrepaired fourth-degree obstetric tears) are encouraging.

Pelvic organ prolapse surgical training program in Bangladesh and Nepal improves objective patient outcomes.

INTRODUCTION AND HYPOTHESIS: The DAK Foundation (Sydney) has facilitated pelvic organ prolapse (POP) repairs performed by local gynecologists for underprivileged women in Bangladesh and Nepal since 2014. Initially, there was no long-term patient follow-up. When 156 patients were examined at least 6 months after their surgery, an unacceptably high rate of prolapse recurrence and shortened vaginas was identified. This demonstrated the need for surgical up-skilling in both countries. Our hypothesis is that the introduction of a surgical training program in low-resource countries can significantly improve patient outcomes after pelvic floor surgery. METHODS: One-on-one surgical re-training was undertaken to up-skill the gynecologists in fascial vaginal repair and vaginal apical reconstruction utilizing sacrospinous fixation (SSF). Following the surgical up-skilling, a further 289 women (between 6 and 18 months post-operatively) were examined to determine patient outcomes. Outcome measures were: 1. Prolapse recurrence: POPQ (pelvic organ prolapse quantification [1]) ≥ stage 2 2. Vaginal length < 4 cm RESULTS: Prior to implementation of the surgical training program, 76% of patients had recurrent prolapse ≥ stage 2, and 56% had a vagina < 4 cm in length. Following the training program, prolapse recurrence was reduced to 45% with significant reductions in the apical, anterior and posterior compartments. The incidence of unacceptable vaginal shortening was 4%. We could not rely on patient symptoms to determine whether they had recurrences. CONCLUSION: Clinical patient follow-up to determine surgical outcome is essential in low-resource settings. We have demonstrated that surgical up-skilling in vaginal hysterectomy, vaginal repair and introduction of SSF were necessary to achieve acceptable prolapse recurrence rates in our programs in Bangladesh and Nepal.

An International Continence Society (ICS) report on the terminology for female pelvic floor fistulas.

INTRODUCTION: The terminology for female pelvic floor fistulas (PFF) needs to be defined and organized in a clinically based consensus Report. METHODS: This Report combines the input of members of the International Continence Society (ICS) assisted at intervals by external referees. Appropriate core clinical categories and a sub-classification were developed to give a coding to definitions. An extensive process of 19 rounds of internal and external review was involved to examine each definition, with decision-making by collective opinion (consensus). RESULTS: A terminology report for female PFF, encompassing 416 (188 NEW) separate definitions, has been developed. It is clinically based with the most common diagnoses defined. Clarity and user-friendliness have been key aims to make it interpretable by practitioners and trainees in different specialty groups involved in female pelvic floor dysfunction and PFF. Female-specific imaging (ultrasound, radiology, and magnetic resonance imaging) and conservative and surgical PFF managements as well as appropriate figures have been included to supplement and clarify the text. Interval (5-10 years) review is anticipated to keep the document updated and as widely acceptable as possible. CONCLUSION: A consensus-based terminology report for female PFF has been produced to aid clinical practice and research.

Vesicovaginal fistula following pelvic surgery: Our experiences and recommendations for diagnosis and prompt referral.

BACKGROUND: Vesicovaginal fistula (VVF) is an uncommon but known complication of pelvic surgery. Post-operative urine leakage should generate a high index of clinical suspicion for early diagnosis of VVF. AIMS: This study aims to identify areas for improvement and provide recommendations for timely and accurate diagnosis of VVF to minimise patient morbidity. MATERIALS AND METHODS: A retrospective observational study of all patients who underwent VVF repairs unrelated to malignancies in a ten-year period at two primary referral centres in Brisbane was performed to review the aetiology, performance of investigative tests and management of these cases. RESULTS: A total of 56 patients were studied with the identification of significant delays to diagnosis and referral, the performance of multiple unnecessary tests and low rates of primary surgeon referral. CONCLUSIONS: Early recognition of VVF and assessment by outpatient methylene blue dye test can provide quick same-day diagnosis and minimise patient suffering. We hope this will alert gynaecologists and provide guidelines for diagnosis and improved management to allow for prompt referral and repair of genitourinary fistula.

Pelvic floor ultrasound findings in Ugandan women with obstetric fistula, unrepaired fourth degree obstetric tear, and pelvic organ prolapse.

BACKGROUND: While pelvic floor ultrasound is commonly utilised in high-resource locations, our understanding of pelvic floor characteristics in women suffering with obstetric fistula and unrepaired fourth degree obstetric tears in low-resource areas is limited. AIMS: This study aimed to assess the pelvic floor ultrasound characteristics of Ugandan women suffering with obstetric fistula, unrepaired fourth degree obstetric tears and pelvic organ prolapse, and determine whether obstructed labour resulting in obstetric fistula causes more levator muscle defects compared to parous women without a history of obstructed labour. MATERIALS AND METHODS: This was a prospective study in western Uganda assessing 82 women with obstetric fistula, unrepaired fourth degree obstetric tears and pelvic organ prolapse with a pelvic floor ultrasound scan. RESULTS: Demographic characteristics were significantly different, with women suffering pelvic organ prolapse being older and more parous. Hiatal area on Valsalva was significantly smaller in the obstetric fistula group (mean 21.45 cm2 ) compared to non-obstetric fistula group (unrepaired fourth degree obstetric tears and pelvic organ prolapse; mean 30.44 cm2 ); a mean difference of 9.0 cm2 (95% CI: 5.4-12.6 cm2 , P < 0.001). Overall, levator muscle defects were significantly more common in women with obstetric fistula (66.7%) compared to the non-obstetric fistula group (44.7%) with P = 0.048; however, there were no significant differences in complete levator muscle defects between obstetric fistula (28.6%) and non-obstetric fistula (23.7%). CONCLUSIONS: Increased hiatal area on Valsalva was noted in the non-obstetric fistula group compared to women with obstetric fistula; however, there were no differences in proportions of complete levator muscle defects.

Incidence of intimate partner violence among Ugandan women with pelvic floor dysfunction.

OBJECTIVE: To assess the occurrence of intimate partner violence (IPV) among women seeking surgery for pelvic floor dysfunction (PFD) in a rural African community. METHODS: A prospective questionnaire-based study was conducted among women with obstetric fistula, unrepaired obstetric anal sphincter injuries (OASIS), or severe (stage 3 or 4) pelvic organ prolapse (POP) who attended surgical camps at Kagando Hospital in western Uganda between July 15, 2016, and September 14, 2017. The control group comprised women without PFD. Participants completed the Hurt, Insult, Threaten, and Scream (HITS) tool and the Woman Abuse Screening Tool (WAST) to screen for IPV. RESULTS: 117 of the 312 women interviewed reported current IPV: 73/214 (34.1%) in the PFD group and 44/98 (44.9%) in the control group. The PFD group comprised unrepaired OASIS (n=85, 39.7%), obstetric fistula (n=75, 35.1%), and severe POP (n=54, 25.2%). All groups experienced high levels of IPV. The frequency of positive screening results for IPV with WAST (score ≥13.0) and/or HITS (score ≥10.5) were: severe POP (n=17, 31.5%), obstetric fistula (n=28, 37.3%), unrepaired OASIS (n=30, 35.3%), and control group (n=44, 44.9%). CONCLUSION: Women in western Uganda experienced high rates of IPV, regardless of whether or not they had PFD. ANZCTR number: ACTRN12617001073392.

A descriptive study on the efficacy and complications of the Capio (Boston Scientific) suturing device for sacrospinous ligament fixation.

BACKGROUND: Sacrospinous colpopexy is an effective vaginal apical support operation. Due to morbidity associated with traditional approaches which require wide dissection, slim-line suture delivery devices have been introduced in the hope of reducing morbidity without compromise to outcomes. AIM: The aim of our series was to report outcomes and complications (particularly buttock pain and blood loss) of the sacrospinous colpopexy using the Capio suturing device and evaluate it against published results using the Miya hook. METHODS: This is a prospective, multi-centre descriptive study. The primary outcome is objective success at 12 months. Secondary outcomes include subjective success at 12 months, patient-reported outcomes at 12 months, operating time, estimated blood loss and post-operative buttock pain. RESULTS: Fifty-one consenting patients undergoing sacrospinous colpopexy were recruited at four Queensland hospitals. Objective success at 12 months was 95% (41/43) and subjective success at 12 months was 92% (44/48). Eighty-four percent of patients reported buttock pain at one week, reducing to 16% by six weeks, of which 7% required analgesia. CONCLUSIONS: At a mean of 17 months follow up, we found that the sacrospinous colpopexy using the Capio suturing device provided excellent apical support with a low requirement for blood transfusion and an average operating time of seven minutes. We found a high rate of buttock pain immediately post-operatively, but our rates became consistent with previous reports by six weeks post-operation.

Parity as a predictor of obstetric fistula classification.

INTRODUCTION AND HYPOTHESIS: Obstetric fistulas are injuries to the genital tract in women without emergency obstetric services. Parity may predict the characteristics of fistulas that affect closure success and residual incontinence. Circumferential fistulas may predispose patients to postoperative incontinence. We hypothesized that primiparous women have more distal fistulas than multiparous women, leading to more scarring and circumferential fistulas. METHODS: A retrospective observational study was conducted on 1,856 women with obstetric fistula evaluated at three sites by three providers. Fistulas were classified using the Goh classification system. Women aged 10 to 55 years were classified as primiparas or multiparas. Analysis by parity of fistula type and size, degree of scarring, and presence of circumferential defect used the Chi squared or Fisher's exact test, and binary logistic regression. RESULTS: Of the 1,841 (99.2 %) women included, 878 (47.7 %) were primiparas and 963 (52.3 %) were multiparas. Primiparas were more likely to have distal fistulas, type 4 being most common (31.5 %), whereas multiparas were more likely to have proximal fistulas, most commonly type 1 (48.1 %). Primiparas were more likely to have moderate to severe scarring (11.7 % vs 5.6 %; p < 0.001), and category III (57.1 % vs 39.2 %; p < 0.001), but not to develop circumferential fistulas (5.6 % vs 4.0 %; p = 0.127), be present for repeat surgery (7.1 % vs 7.6 %; p = 0.721), or have ureteric involvement (1.5 % vs 2.2 %; p = 0.301). Multivariate analyses confirmed increased risk with primiparity for distal fistula and scarring. CONCLUSIONS: As hypothesized, primiparas were more likely to have distal fistulas and more scarring, but were not more likely to have circumferential fistulas. Surgeons should plan accordingly.

Mental health screening in women with severe pelvic organ prolapse, chronic fourth-degree obstetric tear and genital tract fistula in western Uganda.

INTRODUCTION AND HYPOTHESIS: High levels of mental health dysfunction have been identified in women with genital tract fistula. The aim of this study was to use the General Health Questionnaire-28 (GHQ-28) to screen women in western Uganda with severe pelvic organ prolapse, chronic fourth-degree obstetric tear and genital tract fistula for risk of mental health dysfunction. METHODS: Women undergoing surgery for severe pelvic organ prolapse, chronic fourth-degree obstetric tear, and genital tract fistula were interviewed using the GHQ-28 to screen for the risk of mental health dysfunction. RESULTS: A total of 125 women completed the GHQ-28, including 22 with pelvic organ prolapse, 47 with fourth-degree obstetric tear, 21 with genital tract fistula, and 35 controls. Nearly all women with these serious gynaecological conditions were positive for the risk of mental health dysfunction. In the domain assessing symptoms of severe depression, women with fourth-degree obstetric tear and genital tract fistula scored higher than women with pelvic organ prolapse. CONCLUSIONS: A significant risk of mental health dysfunction was identified in women with severe pelvic organ prolapse and chronic fourth-degree obstetric tear. These rates are similar to the high rates of mental health dysfunction in women with genital tract fistula. Identification and management of mental health dysfunction in women with these conditions should be a priority.

Outcomes following surgical repair using layered closure of unrepaired 4th degree perineal tear in rural western Uganda.

INTRODUCTION: In many rural low-income countries, perineal tears at time of vaginal birth are not repaired at time of delivery. The aims of this study are to describe the surgical technique for management of the unrepaired 4th degree tear, performed without flaps, and short-term follow up on anal incontinence symptoms using a validated questionnaire. METHODS: Women presenting to fistula camps in western Uganda with unrepaired 4th degree tears were interviewed using the Cleveland Clinic Continence Score. Interviews were undertaken pre-operatively, at 4-6 weeks post-operatively and 12 months following surgery. Repair of the 4th degree tear was performed in layers, with an overlapping anal sphincter repair and reconstruction of the perineal body, without flaps. All women were examined prior to discharge. RESULTS: 68 women completed pre-operative Cleveland Clinic Continence Scores. Prior to surgery, 59 % of women complained of daily incontinence to solid stools. Over 70 % of women complained of restriction to lifestyle due to the unrepaired 4th degree tear. About 50 % of the women are rejected by their husbands because of the condition. Only 1 woman had wound breakdown on Day 2. At 4 to 6 weeks follow-up, 61 women were contacted and all reported perfect continence. CONCLUSION: This study highlights the hidden problem of unrepaired 4th degree tears in rural areas of low-income countries where most deliveries are undertaken in the village without professional health care workers. These tears have significant impact on quality of life and anal incontinence. Short-term outcomes following surgical repair using a layered closure are promising.

Treatment-seeking behaviour and social status of women with pelvic organ prolapse, 4th-degree obstetric tears, and obstetric fistula in western Uganda.

INTRODUCTION AND HYPOTHESIS: This study looks at a trilogy of women's health issues including severe pelvic organ prolapse, unrepaired 4th degree obstetric tears and obstetric fistula, all of which can cause significant suffering in the lives of women and their families. METHODS: Women undergoing surgery for severe pelvic organ prolapse, unrepaired 4th degree obstetric tears and obstetric fistulae, were interviewed to assess their perceptions of what caused their condition, subsequent impact on their social situation and sexual activity, and whether they had sought treatment previously. RESULTS: One hundred fifty women participated in the survey, including 69 undergoing surgery for genito-urinary fistula, 25 with faecal incontinence only (including 24 women with unrepaired 4th degree obstetric tears and 1 woman with an isolated rectovaginal fistula), and 56 women with severe pelvic organ prolapse. All groups of women were exposed to abandonment by their families with 42 % of women with genito-urinary fistula, 21 % with unrepaired 4th degree obstetric tear, and 25 % of women with severe pelvic organ prolapse rejected by their husbands. Most of the women had actively sought treatment for their condition with no success due to unavailability of treatment or misinformation. CONCLUSIONS: This study confirms the social stigma associated with obstetric fistula, however also highlights the social stigma faced by women suffering with severe pelvic organ prolapse and unrepaired 4th degree obstetric tears in western Uganda. There is an urgent need for education and training in obstetric management and pelvic organ prolapse management in such areas of limited resources.

Use of periurethral injections of polyacrylamide hydrogel for treating post-vesicovaginal fistula closure urinary stress incontinence.

AIMS: Following successful closure of obstetric genitourinary fistula, stress urinary incontinence (SUI) is a common and challenging problem. Despite many decades of various treatment options, the effective management of post-fistula SUI remains unresolved. This study aims to assess the feasibility of periurethral injections of polyacrylamide hydrogel, commonly used for urinary stress incontinence in non-fistula women, in women with post-fistula closure SUI. MATERIAL AND METHODS: Women with urinary incontinence following successful fistula closure were assessed to exclude detrusor overactivity and urinary residual volumes of more than 100 mL. The urethrovesical junction was identified and polyacrylamide hydrogel was injected through the periurethral skin and vaginal epithelium at three sites. RESULTS: Four women with post-fistula SUI were treated with polyacrylamide hydrogel injections. Three of the four women were dry post-operatively and remained continent at discharge. CONCLUSION: In the short-term, periurethral injections of polyacrylamide hydrogel appears to be a promising method to treat post-obstetric fistula urinary stress incontinence.

Cystocele recurrence after anterior colporrhaphy with and without mesh use.

OBJECTIVE: Mesh reinforcement in cystocele repair has become popular in recent years, with some evidence of reduced recurrence rates. In this retrospective cohort series, we aimed to assess subjective and objective outcomes, including ultrasound quantification of prolapse, following anterior colporrhaphy with and without mesh use for anterior compartment prolapse. STUDY DESIGN: We assessed anatomical and functional outcomes of patients after cystocele repair in three tertiary urogynecology units. Outcome measures included either objective prolapse recurrence (defined as cystocele≥Stage 2 ICS POP-Q or bladder descent ≥10mm below the symphysis pubis on ultrasound) or subjective prolapse recurrence (defined as symptoms of vaginal lump, bulge or dragging sensation post-operatively). Comparisons between mesh use and anterior colporrhaphy-only groups were undertaken, adjusting for potential confounders (age, BMI, vaginal parity, previous prolapse repair, levator avulsion and length of follow-up) using multiple linear regression and logistic regression methods. RESULTS: 183 patients were assessed at an average follow-up of 4 years. Eight-three patients had anterior colporrhaphy between January 2002 and December 2005, and 100 had an anterior mesh repair between March 2004 and October 2008. Forty-six (55%) patients in the anterior colporrhaphy group compared to 33 (33%) in the mesh use group were diagnosed with a recurrent cystocele (≥stage 2) (p=0.002). After adjustment for age, BMI, previous vaginal delivery, previous vaginal repair surgery, and length of follow-up, the benefit of mesh on prolapse recurrence was principally experienced by women with major levator trauma. CONCLUSIONS: At a mean of four years' follow-up, mesh augmentation was associated with reduced cystocele recurrence, but this effect was limited to patients with levator avulsion.

Urinary symptoms and urodynamics following obstetric genitourinary fistula repair.

INTRODUCTION AND HYPOTHESIS: The aim of this study was to evaluate urinary symptoms and urodynamic diagnoses in women following repair of obstetric fistula of the lower urinary tract. METHODS: Women with previous genital tract fistula and ongoing urinary symptoms were evaluated at the Addis Ababa Fistula Hospital. The women were referred to the Urodynamic Unit by doctors reviewing women at the hospital. Consecutive women between December 2008 and September 2009 were assessed (including urodynamic studies) and data collected RESULTS: One hundred and fifty-four women were referred for urodynamic assessment. Only women with previous obstetric fistula were included in the study. Of the 154 women, 5 were excluded from the study-1 declined the assessment, 1 had a non-obstetric fistula and 3 were found to have recurrence of the fistula. Forty-nine percent had urodynamic stress incontinence only, 3 % had detrusor overactivity only and 43 % had both urodynamic stress incontinence and detrusor overactivity. Five percent of women had neither detrusor overactivity nor urodynamic stress incontinence. Seven percent had post-void residual volume of 150 ml or more. CONCLUSIONS: Non-surgical management of post-obstetric fistula urinary symptoms may be neglected. The reduced success rates in surgery for post-obstetric fistula urinary incontinence may be due to the lack of attention to the other reasons for urinary symptoms and markedly impaired urethral function. Urethral closure pressures in this group of women often did not reflect the severity of urinary incontinence.
