Abstract
Scaffolds can be introduced as a source of tissue in reconstructive surgery and can help to improve wound healing. Amniotic membranes (AMs) as scaffolds for tissue engineering have emerged as promising biomaterials for surgical reconstruction due to their regenerative capacity, biocompatibility, gradual degradability, and availability. They also promote fetal-like scarless healing and provide a bioactive matrix that stimulates cell adhesion, migration, and proliferation. The aim of this study was to create a tissue-engineered AM-based implant for the repair of vesicovaginal fistula (VVF), a defect between the bladder and vagina caused by prolonged obstructed labor. Layers of AMs (with or without cross-linking) and electrospun poly-4-hydroxybutyrate (P4HB) (a synthetic, degradable polymer) scaffold were joined together by fibrin glue to produce a multilayer scaffold. Human vaginal fibroblasts were seeded on the different constructs and cultured for 28 days. Cell proliferation, cell morphology, collagen deposition, and metabolism measured by matrix metalloproteinase (MMP) activity were evaluated. Vaginal fibroblasts proliferated and were metabolically active on the different constructs, producing a distributed layer of collagen and proMMP-2. Cell proliferation and the amount of produced collagen were similar across different groups, indicating that the different AM-based constructs support vaginal fibroblast function. Cell morphology and collagen images showed slightly better alignment and organization on the un-cross-linked constructs compared to the cross-linked constructs. It was concluded that the regenerative capacity of AM does not seem to be affected by mechanical reinforcement with cross-linking or the addition of P4HB and fibrin glue. An AM-based implant for surgical repair of internal organs requiring load-bearing functionality can be directly translated to other types of surgical reconstruction of internal organs.

Abstract
IMPORTANCE Data comparing perioperative outcomes between transvaginal, transabdominal, and laparoscopic/robotic vesicovaginal fistula (VVF) repair are limited but are important for surgical planning and patient counseling. OBJECTIVE This study aimed to assess perioperative morbidity of VVF repair performed via various approaches. STUDY DESIGN The American College of Surgeons National Surgical Quality Improvement Program database was used to identify women who underwent transvaginal, transabdominal, or laparoscopic/robotic VVF repair from 2009 to 2020. Associations of surgical approach with baseline characteristics, blood transfusion, prolonged hospitalization (>4 days), and 30-day outcomes (any major or minor complication or return to the operating room) were evaluated with χ 2 , Fisher exact, and Kruskal-Wallis tests. Multivariable logistic regression models assessed the adjusted association of approach with 30-day complications and prolonged hospitalization. RESULTS Overall, 449 women underwent VVF repair, including 252 transvaginal (56.1%), 148 transabdominal (33.0%), and 49 laparoscopic/robotic procedures (10.9%). Abdominal repair was associated with a longer length of hospitalization (median, 3 days vs 1 day transvaginal and laparoscopic/robotic; P < 0.001), higher risk of prolonged length of stay (abdominal, 21.1%; transvaginal, 4.0%; laparoscopic/robotic, 2.0%; P < 0.001), major complications (abdominal, 4.7%; transvaginal, 0.8%; laparoscopic/robotic, 0.0%; P = 0.03), and perioperative transfusion (abdominal, 5.0%; transvaginal, 0.0%; laparoscopic/robotic, 2.1%; P = 0.01). On multivariable analysis, the abdominal approach was independently associated with an increased risk of prolonged hospitalization compared with laparoscopic/robotic (odds ratio, 12.3; 95% confidence interval, 1.63-93.21; P = 0.02) and transvaginal (odds ratio, 6.09; 95% confidence interval, 2.87-12.92; P < 0.001) but not with major/minor complications ( P = 0.76). CONCLUSION Transvaginal and laparoscopic/robotic approaches to VVF repair are associated with lower rates of prolonged hospitalization, major complications, and readmission compared with a transabdominal approach.

Abstract
BACKGROUND Vesicovaginal fistula (VVF) due to posterior bladder wall and/or anterior vaginal wall necrosis is a condition that leads to urinary incontinence. Both microscopic and macroscopic VVFs severely impact quality of life. They are also associated with frequent recurrence after surgery. A non-surgical intervention for VVF is urgently required. A membrane bilayer could act as a mechanical tamponade and stimulate defect closure. MATERIAL AND METHODS This is an experimental study that explored the characteristics of mucoadhesive bilayer membrane complexes for non-operative treatment of VVF in vitro. We synthesized a mucoadhesive bilayer membrane, and inoculated it with cultured fibroblast cells. The mucoadhesive bilayer membrane was prepared with 3 different treatments: (1) estrogen; (2) lyophilized radiation-sterilized amnion (ALSR), a prepared amniotic membrane; and (3) arginine and glutamine (arginine+glutamine), 2 amino acids associated with wound repair. Expression levels of 3 genes, namely tumor growth factor beta (TGF-ß), lysil oxidase (LOX), and junctional adhesion molecules (JAMs), were measured using the Livak method and polymerase chain reaction (PCR). RESULTS On the fifth day after inoculation, there was no statistically significant difference in expression of the genes in the 3 conditions. However, on the tenth day, gene expression of the LOX and JAMs genes in the fibroblast cells inoculated onto the mucoadhesive bilayer membrane with arginine+glutamine was significantly higher than the expression in the fibroblast cells inoculated onto the mucoadhesive bilayer membrane with estrogen or with ALSR. CONCLUSIONS The mucoadhesive bilayer membrane complex with arginine+glutamine gave rise to the highest expression of the LOX and JAMs genes, indicating that the highest proliferation and cell adhesion were found in cells inoculated with the mucoadhesive bilayer membrane complex with arginine+glutamine.

Abstract
This report presents the case of a 63-year-old woman who developed a vesicovaginal fistula as a complication of a previous total hysterectomy. The fistula was treated with the use of the da Vinci X surgical system by a multi-disciplinary operating team, including senior Robotic Urological and Gynecological Surgeons at St. Luke's Hospital in Thessaloniki, Greece. The patient was monitored up to 12 months post-op at the time of writing and she was asked to evaluate post-op quality of life using the SF-36 and ICIQ-SF-UI questionnaires. The robotic surgical procedure was completed successfully. The total operation duration was 105 minutes, without any intra-operative complications. The patient was hospitalized for two days and made a swift, uneventful recovery. Regarding the quality of life, the patient reported satisfactory improvement in almost every domain assessed compared to her pre-op assessment; an improvement that was maintained throughout the reported follow-up period. At the time of writing, the patient reports no long-term complications and satisfactory urinary continence. Robotic-assisted laparoscopic vesicovaginal fistula repair is an effective and safe treatment option for this rare complication, as indicated by both post-operative data and the patient's own self-evaluation in this report. Further research is warranted, focusing on refining the surgical technique and comparing this to other alternative methods aiming to further improve patient outcomes.

Abstract
OBJECTIVES We aimed to report the background of patients with vesicovaginal fistulas (VVFs) at our center, which has treated a relatively large number of such patients in Japan, as well as the ingenuity and outcomes of vesicovaginal fistula closure (VVFC). We also investigated the causes of VVFs. METHODS A retrospective review was performed for 28 patients with VVFs treated at our center. Age, body mass index, etiology, site of fistula, and postoperative outcomes were investigated. RESULTS Twenty-one (75%) fistulas occurred following hysterectomy. The overall success rate of VVFC was 85.7%, and the success rate limited to the first attempt was 89.5%. In 68% of cases, no bladder injury suspected as the cause of VVF was noticed during the surgery. Energy devices were used in all 12 patients for whom information on the type of device used for hysterectomy was confirmed. CONCLUSIONS To our knowledge, this is the first report to evaluate a relatively large number of VVFCs in Japan. Although VVF is thought to be caused by bladder injury during hysterectomy, delayed thermal damage might also result in this pathology, even if there is no apparent intraoperative bladder injury.

Mechanical reinforcement of amniotic membranes for vesicovaginal fistula repair. J Mech Behav Biomed Mater 2023; 139:105680. [PMID: 36701851 DOI: 10.1016/j.jmbbm.2023.105680] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 11/23/2022] [Accepted: 01/11/2023] [Indexed: 01/15/2023]
Abstract
INTRODUCTION Amniotic membranes (AM) have shown its great potential in reconstructive surgery due to their regenerative capacity. However, AM is regarded to be relatively weak when applied for load-bearing purposes. This study aims to produce an AM-based scaffold that can withstand the mechanical loads applied in vesicovaginal fistula repair. Different strategies are investigated to improve the mechanical characteristics of AM. METHODS Single and multilayered AM, and composite constructs of AM with electrospun poly-4-hydroxybutyrate (P4HB) or bovine pericardial tissue combined with the use of fibrin glue, were mechanically tested in this study. Suture retention strength and mechanical characteristics (tensile stress, elongation, tangent modulus and maximum load) were assessed by uniaxial testing. The effect of degradation of the composite constructs on the mechanical characteristics was determined by uniaxial testing after 4 and 8 weeks. RESULTS Single and multilayered AM could not provide the mechanical requirements needed for surgical implantation (>2N load). AM was combined successfully with electrospun P4HB and bovine pericardium with the use of fibrin glue and were able to exceed the 2N load. CONCLUSION The composite constructs with AM showed sufficient mechanical characteristics for surgical implantation. Electrospun P4HB combined with AM seemed the most promising candidate since the mechanical characteristics of P4HB can be further modified to meet the requirements of the application site and the degradation of the P4HB allows a gradual transfer of load. Eventhough the scaffold is intended for fistula repair, it can potentially be applied in surgical reconstruction of other hollow organs by modifying the mechanical characteristics.

Abstract
The main aim of our study was to describe the surgical technique and evaluate the feasibility, efficacy and safety of a vaginal-laparoscopic repair (VLR) of iatrogenic vesico-vaginal fistulae (VVF). Between April-2009 and November-2017, we retrospectively reviewed all clinical, radiological and surgical details of surgery for benign or malignant disease and ended up with VVF. All patients were diagnosed by CT urogram, cystogram and clinical test. The surgical technique was standardised and is described here. Eighteen patients developed VVF after hysterectomy, three after caesarean section and three after hysterectomy and pelvic lymphadenectomy. Twenty-two patients had an average 3 (range 1-5) attempts at fistula repair in other hospitals. In one patient, five attempts were made. The mean size of the fistula was 2.4 cm (range 0.7-3.1 cm). A median 8 weeks (6-16) conservative management with Foley catheter failed in all patients. No conversion to laparotomy and no complication occurred at VLR. Median hospitalisation was 1.4 days (range 1-3). The latter confirmed all patients were dry and tested negative at a repeated filling test. At 36 months follow-up, all patients remained dry. In conclusion, VLR successfully repaired VVF in all patients with primary and persistent VVF. The technique was safe and effective.

Abstract
Background: To evaluate the efficacy of double percutaneous nephrostomy (PCN) combined with ureter occlusion stent for treating cervical cancer complicated with vesicovaginal fistula (VVF). Materials and Methods: A retrospective analysis was performed for 12 patients with cervical cancer complicated with VVF. Regardless of surgical resection, radiotherapy alone or combined chemoradiotherapy were carried out in all patients. After VVF was diagnosed by gynecological examination, imaging, and cystoscopy, concurrent double PCN and ureter occlusion stent implantation were performed for all patients. Results: All patients successfully received ureter occlusion stent implantation after nephrostomy. The success rate of nephrostomy and stent placement was 100% (12/12). After intervention, urinary fistula immediately disappeared in all patients. One week post-surgery, bilateral hydronephrosis disappeared in 4 patients, and their renal insufficiency and renal function returned to normal. One month after operation, 6 patients with genital eczema or ulcer and 5 patients with urinary tract infection were cured. During follow-up, there were no recurrence in urinary fistula, renal dysfunction, and other complications. Conclusion: Double PCN combined with ureter occlusion stent could effectively treat cervical cancer complicated with VVF hydronephrosis, urinary tract infection, and renal insufficiency and contribute to alleviate all kinds of clinical discomfort.

Abstract
INTRODUCTION AND HYPOTHESIS There are limited data comparing patient and operative characteristics for vaginal repair of vesicovaginal fistula (VVF) by surgeon specialty. Our objective was to compare national practice patterns by surgeon specialty for vaginal repair of VVF. METHODS Using the American College of Surgeons National Surgical Quality Improvement Program database, we conducted a retrospective cohort analysis of women who underwent vaginal repair of VVF from 2010 to 2019. Demographic and perioperative characteristics were compared by surgeon specialty. RESULTS A total of 252 women were analyzed. Urologists performed 57% of cases (n=144), gynecologists performed 38% (n=96), and general surgeons performed 5% (n=12). There were differences among surgeon specialties in patient characteristics including age (p=0.002), creatinine (p=0.002), hypertension (p=0.02), morbidity probability (p<0.001), hospital stay (p<0.001), inpatient status (p=0.03). Urologists were more likely than gynecologists to use grafts/flaps (p=0.002). There were trending differences among surgeon specialties in patient race (p=0.07) and ethnicity (p=0.06). Urologists and gynecologists were more likely to operate on younger, healthier patients with differences in racial populations. When directly comparing urologists with gynecologists, there were differences in race (p=0.05) and a trending difference in ethnicity (p=0.06), General surgeons were more likely to operate on older white women with worse health status, more concomitant procedures, and longer hospital stay. CONCLUSIONS Urologists, gynecologists, and general surgeons perform vaginal repair of VVF. Among these specialties, there were differences in patient and perioperative characteristics. This information may help referring providers and patients to understand which types of surgical providers most commonly manage VVF.

Abstract
INTRODUCTION AND HYPOTHESIS Studies on non-obstetric urogenital fistulas (NOUGFs) provide limited information on predictive outcome factors. This study was aimed at specifying and analyzing the risk factors for long-term anatomical and functional results. METHODS A cross-sectional study of surgical repair for non-obstetric urogenital fistula was performed. From 2012 to 2020, a total of 479 patients with urogenital fistulas were treated in two tertiary centers. Patients with isolated ureteral fistulas and rectal injuries were excluded. For evaluation of the long-term results, patients with vesicovaginal and urethrovaginal fistulas with at least 12 months of follow-up were identified and contacted by phone and/or examined in the clinic. The anatomical outcome was assessed by resolution of symptoms and/or clinical examination. The Urinary Distress Inventory (UDI-6) was used for the functional outcomes. RESULTS Overall, 425 patients were studied (mean age was 49.8; BMI 27.5; mean fistula size 1.4 cm, mean follow-up was 12 months). Vesicovaginal fistula affected 73% of patients. Hysterectomy without radiation was the most common etiology (66.3%), followed by hysterectomy with subsequent radiation (16%) and pelvic radiotherapy (12.2%). The transvaginal approach was used in 54.4%, abdominal in 12.4%, transvesical in 22.4%, and a combined approach in 10.8%. The successful closure rate was 92.9% for primary cases, 71.6% for secondary cases, and 66.7% for radiation fistulas. A high risk for relapse was found for NOUGFs with ureteral involvement (RR 2.5; 95% CI 1.3-4.5; p = 0.003), radiation fistulas (RR 2.1; 95% CI 1.3-3.5, p = 0.003); and combined radiation and hysterectomy cases (RR 2.9; 95% CI 1.8-4.6; p = 0.0001). In multifactorial analysis, fistula size >3.0 cm, pelvic radiation, and previous vaginal surgeries were associated with a higher risk for failure or lower urinary symptoms. CONCLUSIONS Factors for successful NOUGF closure are fistula size less than 3.0 cm, absence of pelvic radiation, and previous vaginal surgeries.

Abstract
Vesicovaginal fistulas (VVaFs) are relatively uncommon in developed countries but with devastating consequences for the women suffering them. Conservative management has a low response rate. The surgical repair is a technically demanding procedure. Transvaginal, open transabdominal or laparoscopic (pure or robot-assisted) approaches have been described with similar post-operative results. We report two real-life cases of VVaF after surgery of benign gynaecological conditions, both presenting with continuous urinary incontinence and repaired with laparoscopic surgery. The first case had a simple tract above the trigone and was managed with an extravesical approach. The second is a complex case with multiple fistulous tracts that required a transabdominal-transvesical approach (modified O’Connor technique). Both patients have their fistula closed and are continent after surgery with a mean follow-up of 9 months. Given the lack on evidence for the selection of the best approach, it is important to report the outcomes with the different surgical techniques in both simple and complex fistulae. A pre-operative exhaustive study of the location and number of fistulous tracts is essential, as well as selecting the technique which best allows tissue dissection and tension-free suture to get a successful closure. Therefore, knowledge of several procedures and approaches is mandatory when dealing with this disorder.

Abstract
Background Urinary fistula (UF) is a global health problem but less common in well-resourced countries. Over the past decade there has been a trend toward managing UF in dedicated centres. Most of the evidence for surgical treatment is from individual case series, with few publications that involve high numbers. We describe the repair of recurrent and complex UF cases and outcomes in a tertiary referral setting. Objective To describe UF aetiology, repair techniques, and outcomes. Design setting and participants This is a retrospective study of a series of patients undergoing UF repair at a specialist unit. Outcome measurements and statistical analysis We describe the aetiology, cure rate, complications, and postoperative urinary incontinence rates for the series of UF cases. Results and limitations A consecutive series of 98 patients was identified, all of whom were tertiary referrals. Of these, 31 (31.6%) had at least one prior attempt at repair at another centre. The median age was 48 yr (interquartile range [IQR] 40-60.25). The median time from occurrence to repair was 12 mo (IQR 6-12). UF occurred most commonly following hysterectomy (48.0%), Caesarean section (9.2%), other gynaecological surgery (7.1%), and anti-incontinence surgery (7.1%). Complex fistulae (eg, repeat cases, radiation, ureteric involvement) comprised 41 of the cases (41.8%). Most patients with vesicovaginal fistula underwent repair via a transabdominal approach (70.4%). Tissue interposition was used in 96 cases (98%). There were no Clavien-Dindo grade >3 complications. Two patients (2%) had a persistent UF postoperatively. Two patients (2%) developed recurrence more than 2 yr after their initial repair, and both were successfully repaired at our centre. Twelve patients (12.3%) developed de novo overactive bladder, 22 (22.5%) developed stress urinary incontinence (13 had subsequent incontinence surgery), and two (2%) developed bladder pain (both had a subsequent cystectomy). Conclusions Despite a high rate of recurrent and complex UF, successful lasting closure was achieved in 96% of our cases. A minority of patients developed other problems such as de novo overactive bladder and stress urinary incontinence that may require further treatment. Patient summary Urinary fistula is an abnormal opening or connection in the urinary tract and is less common in well-resourced countries. As a consequence, management of this condition is more frequently undertaken at specialist units. Even patients with a complex fistula and those who have had multiple attempts at repair can experience a cure. Urinary leakage is a common complication after the operation but can be successfully managed with surgery.

Abstract
Lower urinary tract (LUT) injuries may occur during gynecologic surgery due to the close proximity of pelvic organs and vary by procedure, surgical indication, and route. Prevention of LUT injury should be a primary goal of gynecologic surgery. LUT injuries are more common in patients with aberrant anatomy, during difficult procedures, and with surgeons with less experience. Immediate recognition and management of LUT injuries is optimal, although delayed postoperative diagnoses may be unavoidable. Surgical management is based on the size and location of injury and should be performed by an experienced surgeon with thorough knowledge of pelvic anatomy, surgical technique, and postoperative management.

Abstract
Objectives: To describe our multi-institutional experience with robotic repair of iatrogenic urogynecologic fistulae (UGF), including vesicovaginal fistulae (VVF) and ureterovaginal fistulae (UVF). Methods: We performed a retrospective review identifying patients who underwent robotic repair of VVF and UVF between January 2010 and May 2019. All patients failed conservative management with Foley catheter or upper tract drainage (ureteral stent and/or nephrostomy tube), respectively. Patient demographics and perioperative outcomes were analyzed. Success was defined as no vaginal leakage of urine postoperatively, in the absence of drains, catheters, or stents. Results: Of 34 patients, 22/34 (65%) had VVF and 12/34 (35%) had UVF repair. VVF etiology included radiation (1/22, 4.5%) and surgery (21/22, 95.5%). Four of 22 (18%) had undergone prior repair attempt. Median console time was 187 minutes (interquartile range [IQR]: 151-219), estimated blood loss (EBL) was 50 mL (IQR: 50-93), and median length of stay (LOS) was 1 day (IQR: 1-2). Two of 22 (9%) patients had a postoperative complication. At mean follow-up of 28.9 months, 20/22 (91%) VVF cases were clinically effective. UVF etiology was gynecologic surgery in all cases; 8/12 (67%) were left-sided, 4/12 (33%) were right-sided. None was repeat repairs. Two of 12 (17%) underwent ureteroureterostomy, and 10/12 (83%) had reimplant. Median console time was 160 minutes (IQR: 133-196), EBL was 50 mL (IQR: 50-112), and LOS was 1 day (IQR: 1-1). No complications were encountered. At mean follow-up of 29.3 months, 100% of UVF repairs were effective. Conclusions: Robotic repair of iatrogenic UGF may be effectively performed with low complication rates by experienced urologic surgeons.

Abstract
With the widespread dissemination of robotic surgical platforms, pathology previously deemed insurmountable or challenging has been treated with reliable and replicable outcomes. The advantages of precise articulation for dissection and suturing, tremor reduction, three-dimensional magnified visualization, and minimally invasive trocar sites have allowed for the management of such diverse disease as recurrent or refractory bladder neck stenoses, and radiation-induced ureteral strictures, with excellent perioperative and functional outcomes. Intraoperative adjuncts such as near-infrared imaging aid in identification and preservation of healthy tissue. More recent developments include robotics via the single port platform, gender-affirming surgery, and multidisciplinary approaches to complex pelvic reconstruction. Here, we review the recent literature comprising developments in robotic-assisted genitourinary reconstruction, with a view towards emerging technologies and future trends in techniques.

Abstract
Background Genitourinary emergencies in cancer patients are common. Most cancer treatments are administered in the outpatient setting, and patients with complications often visit the emergency department. However, there is no recent emergency medicine literature review focusing on genitourinary emergencies in the oncologic population. Objective of the review. To increase awareness of common genitourinary emergencies in patients with cancer and enable the prompt recognition and appropriate management of these conditions. Discussion. Genitourinary emergencies in patients with cancer require a multidisciplinary approach to treatment. The most common genitourinary emergencies in patients with cancer are related to infection, obstructive uropathy, hemorrhagic cystitis, and complications associated with urinary diversions. The treatment approach in patients with infections, including viral infections, is similar to those without cancer. Understanding the changes in the anatomy of patients with urinary diversions or fistulas can help with the management of genitourinary emergencies. Conclusions Familiarization with the uniqueness of genitourinary emergencies in patients with cancer is important for emergency physicians.

Abstract
Background Vesicovaginal fistulas (VVF) are an unusual problem that may significantly affect a patient's quality of life. The main causes for this condition are labour complications (mostly in developing countries) and pelvic surgeries (in industrialised countries). Treatment may be conservative or surgical. Regarding surgical treatment, there is still debate about the best approach and surgical technique. Objective To demonstrate a correction of a VVF guided by cystoscopy using intravesical laparoscopic instruments. Methods Case report and surgical video of a recurrent VVF treated with a hybrid technique involving direct transvesical insertion of 3 mm laparoscopic trocars and instruments guided by cystoscopy. As far as we know, although there are some reported techniques that use a combination of transvesical laparoscopic instruments and cystoscopy, this is the least invasive and most ergonomic technique described. Results Two years after surgery, the patient remains asymptomatic and with no fistula recurrence. Conclusion The transvesical approach guided by cystoscopy seems to be an effective, safe and ergonomic minimally invasive procedure for VVF repair.

Abstract
Currently, there are no clinically available tissue adhesives that work effectively in the fluid-rich and highly dynamic environments of the human body, such as the urinary system. This is especially relevant to the management of vesico-vaginal fistula, and developing a high-performance tissue adhesive for this purpose could vastly expand urologists' surgical repertoire and dramatically reduce patient discomfort. Herein, we developed a water-immiscible mussel protein-based bioadhesive (imWIMBA) with significantly improved properties in all clinical respects, allowing it to achieve rapid and strong underwater adhesion with tunable rheological properties. We evaluated in vivo potential of imWIMBA for sealing thermally injured fistula tracts between the bladder and vagina. Importantly, the use of imWIMBA in the presence of prolonged bladder drainage resulted in perfect closure of the vesico-vaginal fistula in operated pigs. Thus, imWIMBA could be successfully used for many surgical applications and improve treatment efficacy when combined with conventional surgical methods. STATEMENT OF SIGNIFICANCE: Vesico-vaginal fistula (VVF) is an abnormal opening between the bladder and the vagina, which is a stigmatized disease in many developing countries. Leakage of urine into internal organs can induce serious complications and delay wound repair. Conventional VVF treatment requires skillful suturing to provide a tension-free and watertight closure. In addition, there is no clinically approved surgical glue that works in wet and highly dynamic environments such as the urinary system. In this work, for potential clinical VVF closure and regeneration, we developed an advanced immiscible mussel protein-based bioglue with fast, strong, wet adhesion and tunable rheological properties. This regenerative immiscible bioglue could be successfully used for sealing fistulas and further diverse surgical applications as an adjuvant for conventional suture methods.

Abstract
The study aims to evaluate the effectiveness of local injection of autologous platelet rich plasma (A-PRP) as a treatment for women suffering from stress urinary incontinence (SUI). In a prospective intervention study, twenty consecutive women suffering from SUI were treated with A-PRP injection at anterior vaginal wall where mid-urethra locates. Self-reported questionnaires were used to measure pre-treatment, 1 month and 6 months post-treatment symptom severity. Secondary outcomes of sexual function and treatment effect sorted by age were analyzed with valid statistical methods. A-PRP is effective in relieving SUI symptoms at both 1 month and 6 months post-treatment without significant adverse reactions reported. It seems to have a trend that treatment success rate with cured and improved symptoms was slightly higher in the younger group, although it did not reach statistical significance (P = 0.07). No significant changes in sexual function before and after the treatment were reported by the patients. This pilot study is the first to report A-PRP treatment effect for SUI in women. The result suggested that A-PRP is a considerable treatment option for mild to moderate SUI cases. It also opens up further research opportunities for A-PRP’s clinical applications.

Cost-effectiveness Analysis of Universal Cystoscopy at the Time of Benign Laparoscopic Hysterectomy. J Minim Invasive Gynecol 2020; 28:1470-1483.

Abstract
STUDY OBJECTIVE To estimate the rate of lower urinary tract injury (LUTI) and percentage of LUTI needing to be recognized intraoperatively to make universal cystoscopy cost-effective and cost-saving during laparoscopic hysterectomy. DESIGN A decision tree model was used to estimate the costs and quality-adjusted life years associated with delayed or intraoperative recognition of LUTI at the time of laparoscopic hysterectomy. Probabilities and utilities were estimated from published literature. Costs were estimated from Medicare national reimbursement schedules. Threshold analyses estimated the LUTI rate and cystoscopy sensitivity that would make universal cystoscopy cost-effective or cost-saving. Monte Carlo simulations were performed. SETTING US healthcare system. PATIENTS Individuals undergoing laparoscopic hysterectomy for benign indications. INTERVENTIONS Theoretic implementation of a universal cystoscopy policy. MEASUREMENTS AND MAIN RESULTS The total direct medical costs of laparoscopic hysterectomy under usual care were $8831 to $9149 and under universal cystoscopy were $8944 to $9068. When low LUTI rates (0.44%; estimated using sample-weighted estimates of retrospective and prospective data) were assumed, universal cystoscopy was only cost-effective in 17.1% of the simulations; the incremental cost was estimated to be $111 to $131. With median LUTI rates (2.3%) or high LUTI rates (4.0%; estimated using only prospective data with universal screening), the universal cystoscopy strategy was cost-effective in 93.9% and 99.6% of the simulations, respectively, and potentially cost-saving if the sensitivity of intraoperative cystoscopy for ureteral injury exceeded 65% or 31%, respectively. The estimated potential savings were $18 to $95 per hysterectomy. In threshold analysis assuming the average cystoscopy sensitivity rate, universal cystoscopy is estimated to be cost-effective when the LUTI rate exceeds 0.80%. CONCLUSION In our model, universal cystoscopy is the preferred approach for laparoscopic hysterectomy and is estimated to be cost-effective in contemporary clinical settings where the LUTI rate is estimated to be 1.8% and potentially cost-saving among higher-risk populations, including those with endometriosis or pelvic organ prolapse. If the LUTI rates are less than 0.75%, the estimated incremental costs are modest-up to $131 per case. Administrators and providers should consider the local LUTI rates and practice patterns when planning implementation of a universal cystoscopy policy.

Abstract
INTRODUCTION AND HYPOTHESIS In developed countries urogenital fistulas are rare and usually a complication of surgery or radiation therapy. Surgical repair can be accomplished transvaginally or by laparotomy, laparoscopy, robotic-assisted laparoscopy, or transurethral endoscopy. Closure can be achieved with or without tissue interposition. The vaginal approach is the least invasive and a variety of techniques with or without tissue interpositions and flaps have been described. This study reviews surgical approaches and techniques for the repair of nonradiogenic urogenital fistulas. METHODS We identified and reviewed records from all patients treated for urogenital fistulas at our unit between 2008 and 2018. We analyzed fistula location, etiology, type and duration of corrective surgery, length of hospitalization, as well as complication and success rates. RESULTS Fifty patients (mean age 52 years) were identified. 49 fistulas were related to previous gynecological surgery, 3 were related to obstetric trauma. Thirty-four patients had vesicovaginal, 11 urethrovaginal, 3 ureterovaginal, and 2 neobladder-vaginal fistulas. Forty-eight patients (96%) were operated on using a vaginal approach; a modified Sims-Simon repair was used in 47 cases (94%). No flaps or tissue interpositions were used. In 48 patients (96%) successful closure was achieved with one operation; the modified Sims-Simon technique was successful in all 47 cases. The median operation time was 40 min (range, 20-100 min); the complication rate was 14%. CONCLUSIONS This series demonstrates the feasibility and advantages of vaginal repair of benign gynecological fistulas. The success rate was high and extensive procedures were avoided.

Abstract
BACKGROUND Fistula repair in the perineal region represents a major challenge for surgeons. It is important for the medical community to facilitate and disclose these techniques. OBJECTIVE The aim of this article was to show a stepwise approach for a direct repair and use of a Martius flap for a vesicovaginal fistula. METHODS We show a single case performed in a patient who presented with a vesicovaginal fistula diagnosed after surgery, which did not respond to conservative management. The procedure consists of the following steps: intraoperative cystoscopy, anatomical direct repair of the fistulous tract between the bladder and vagina, and modified Martius flap. CONCLUSIONS Martius flap is a repair technique used for complex fistula in the perineal region. It is a simple, safe, and reproducible procedure with good long-term functional and esthetic results.

Eur Urol Focus 2020; 7:1485-1492. [PMID: 32747296 DOI: 10.1016/j.euf.2020.06.017] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Revised: 06/14/2020] [Accepted: 06/25/2020] [Indexed: 11/17/2022]
Abstract
BACKGROUND A vesicovaginal fistula (VVF) is an abnormal communication between bladder and vagina, as a result of traumatic events to the female pelvis. A VVF is a rare event and challenging to cure. Successful treatment can be achieved through an abdominal approach, especially in complex or recurrent cases. This approach has been used in our institution as the procedure of choice for the past 50yr. OBJECTIVE To analyze the results of the management of VVFs in our institution and to highlight the key points for success. DESIGN, SETTING, AND PARTICIPANTS A total of 138 patients with VVFs have been treated in our institution between 1969 and 2019. Up to now, this is the largest series reported so far on abdominal treatment of VVFs in the developed world. INTERVENTION an abdominal transvesical approach has been performed as the procedure of choice. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: to evaluate the factors influencing the success rate of the abdominal approach at the first closure attempt. Statistical analysis was performed using STATA software. RESULTS AND LIMITATIONS In total, 124 (90%) patients were submitted to transabdominal repair (89 extraperitoneal; 71.8%), 113 (91.1%) presented with a VVF not associated with another fistula, and 36 (29.0%) had undergone previous unsuccessful treatments elsewhere. Successful closure was obtained in 111/118 (94.1%) patients at the first attempt, excluding external noncontinent urinary diversions. Follow-up was possible in 95 (76.6%) patients; 91 (95.8%) patients were dry. Statistical analysis showed a significant association between fistula size and length, and VVF site in the bladder and extraperitoneal approach. Success rate decreased with the number of previous attempts and did not vary with VVF etiology. CONCLUSIONS The abdominal approach for the treatment of VVF has a high success rate. Standardization of the technique, identification of surgical key points, and centralization of care in centers with experience are critical. PATIENT SUMMARY A vesicovaginal fistula (VVF) is a rare clinical condition, with a high impact on patients' quality of life. We report a large series of VVFs treated in our institution in the past 50yr. Key factors for success include proper surgical technique and centralization of care in centers with high experience.

Abstract
CONTEXT Surgical repair of a vesicovaginal fistula (VVF) has been described extensively in the literature for several decades. Advances in robotic repair have been adopted since 2005. OBJECTIVE A consensus review of existing data based on published case series, expert opinion, and a survey monkey. EVIDENCE ACQUISITION This document summarizes the consensus group meeting and survey monkey results convened by the European Association of Urology Robotic Urology Section (ERUS) relating to the robotic management of VVF. EVIDENCE SYNTHESIS Current data underline the successful robotic repair of supratrigonal nonobstetric VVF. The panel recommends preoperative marking of the fistula by a guidewire or ureteral catheter, and placement of a protective ureteral JJ stent. An extravesical robotic approach usually provides a good anatomic view for adequate and wide dissection of the vesicovaginal space, as well as bladder and vaginal mobilization. Careful sharp dissection of fistula edges should be performed. Tension-free closure of the bladder is of utmost importance. Tissue interposition seems to be beneficial. The success rate of published series often reaches near 100%. An indwelling bladder catheter should be placed for about 10 d postoperatively. CONCLUSIONS When considering robotic repair for VVF, it is essential to establish the size, number, location, and etiology of the VVF. Robotic assistance facilitates dissection of the vesicovaginal space, harvesting of a well-vascularized tissue flap, and a tension-free closure of the bladder with low morbidity for the patient being operated in the deep pelvis with delicate anatomical structures. PATIENT SUMMARY Robotic repair of a vesicovaginal fistula can be applied safely with an excellent success rate and very low morbidity. This confirms the use of robotic surgery for vesicovaginal fistula repair, which is recommended in a consensus by the European Association of Urology Robotic Section Scientific Working Group for reconstructive urology.

Abstract
Recent research has been successful in demonstrating the importance of the addition of platelets to the field of cell-mediated therapeutics, by making use of different platelet forms to design modalities able to positively impact a wide range of diseases. A key obstacle hindering the success of conventional therapeutic interventions is their inability to produce targeted treatment, resulting in a number of systemic side effects and a longer duration for the onset of action to occur. An additional challenge facing current popular therapeutic interventions is biocompatibility of the system, resulting in the decline of patient compliance to treatment. In an attempt to address these challenges, the past few decades have been witness to the discovery and innovation of precision therapy, in order to achieve targeted treatment for an array of conditions, thereby superseding alternative mechanisms of treatment. Platelet-mediated therapeutics, as well as employing platelets as drug delivery vehicles, are key components in advancing precision therapy within research and in clinical settings. This novel approach is designed with the objective that the platelets retain their original structure and functions within the body, thereby mitigating biocompatibility challenges. In this article, we review the current significant impact that the addition of platelet-inspired systems has made on the field of therapeutics; explore certain limitations of each system, together with ideas on how to overcome them; and discuss the clinical implications and future potential of platelet-inspired therapeutics.

Abstract
Background Single port (SP) robotic assisted laparoscopic surgery was approved by the FDA for urologic surgery and clinically available in 2018. This new robotic system enables a camera and 3 separate instruments, with fully wristed motions, to be placed through a single 25 mm port. This system was designed to perform complex surgery in narrow deep spaces making it very suitable for complex urinary tract reconstruction surgery. This paper will describe our early experience of using the SP system for several types of urinary reconstruction procedures and will present our lessons learned, surgical philosophy to using the SP and early data. As with all new technologies, there is an associated learning curve and nuances to be discovered and overcome. Methods The da Vinici SP™ surgical system was acquired and delivered to at our institution in January 2019. Five high volume robotic urologic surgeons at our institutions underwent certification with the da Vinci SP™ and have been adding this technology into their armamentarium. Almost all cases were recorded for quality improvement initiatives and evaluated with the goal of creating standard operating procedures in terms of access, steps of procedure and minimizing pit falls. Data from all patients undergoing SP urinary tract reconstruction that were entered into our prospective institutional database were reported. Results From 1/2019 to 8/2019 we have performed 71 urologic SP cases with the SP of which 18 were for urinary tract reconstructive procedures. These cases included 15 pyeloplasties, 1 buccal mucosa ureteroplasty, 1 ureteral implant and 1 repair of vesico-vaginal fistula. This paper outlines our standard operating procedures for table positioning, port placement, access and surgical steps for these complex SP cases. Our early data suggests that use of the SP system for urinary reconstruction is safe and reproducible. Conclusions The SP robotic surgical system has the potential to be used for nearly all robotic urologic reconstructive procedures. Advantages include a superior cosmetic result and ability to access all surgical quadrants without re-docking or repositioning. Limitations include no near infrared fluorescence imaging, smaller working space and slightly increased difficulty with retraction. We believe these obstacles will be overcome with time and experience. The da Vinci SP™ surgical system, in our initial experience, appears to be as safe and effective as its multiport counterpart for reconstructive surgeries.

Abstract
INTRODUCTION AND HYPOTHESIS Vesicovaginal fistulae (VVF) repair success rates for simple surgical fistulae are high, but constitute a significantly greater challenge when occurring in a radiotherapy field. We aim to evaluate the causes, assessment, closure rates and functional outcomes of VVF surgery in patients with previous radiotherapy. METHODS Data on all VVF repairs were collected prospectively. A retrospective review of outcomes in those with VVF performed between 2009 and 2018 was carried out. Details including time from radiotherapy, pre-operative assessments, approach to surgery and functional outcome were analysed. RESULTS Twenty women with VVFs were identified. The mean age was 59 (range 25-88) years. Primary malignancy was cervical in 16 women, with the remaining 4 women having ovarian, urethral, endometrial and rectal cancer respectively. All women had external beam radiotherapy with 6 (30%) undergoing boosted brachytherapy. Mean interval between radiotherapy and fistula repair was 19 (range 0-40) years. Fistulae arose spontaneously in 14 patients, whereas 6 occurred following a further surgical intervention.Closure was attempted vaginally in 7 women and abdominally in 1, whereas 12 had a primary diversion owing to significant bladder contracture and ureteric involvement. The closure rate in those attempted was 62.5%, 40% in those with spontaneous fistulae compared with 100% for post-surgical fistulae, but only 20% for the total cohort. CONCLUSIONS Closure of VVF is a significant challenge, with an initial success rate of 20% and an overall success rate of only 25%. Seventy percent required primary or secondary urinary diversion. Vaginal surgery was utilised in the majority to try to avoid a hostile pelvis, but the surgical approach should be tailored to individual circumstances.

Abstract
OBJECTIVE To explore the experiences of women living with Obstetric Fistula in Ghana. DESIGN A descriptive qualitative design involving face-to-face semi-structured interviews following institutional ethical approval. SETTING Urban and rural setting in the Mfantseman Municipal Area (MMA) in the Central Region (CR) of Ghana PARTICIPANTS: A purposive sample of thirty- two women who had experienced obstetric fistula (OBF) FINDINGS: Three core themes emerged and these were i) Women's perceptions of OBF, ii) Experiences of women living with OBF iii) Coping strategies of women living with OBF CONCLUSION AND IMPLICATIONS FOR PRACTICE: There is a need for a multi-agency coordinated approach to the treatment and management of OBF in Ghana. The findings support the need for a dedicated specialist fistula centre to treat women and to meet the educational needs of health care professionals with strategies to prevent as well as support women with OBF. The hub and spoke organisation design for health care systems has proved beneficial in other health settings providing a level of quality that would not be possible otherwise. It is time to end the suffering of women living with obstetric fistula.

Abstract
Vaginal fistulas (VF) represent abnormal communications between the vagina and either the distal portion of the digestive system or the lower urinary tract, but lack an accepted classification and standardised terminology. Regardless of the underlying cause, these uncommon disorders result in profound physical, psychological, sexual and social distress to the patients.Since diagnosis of VF is challenging at gynaecologic examination, ano-proctoscopy and urethro-cystoscopy, imaging is crucial to confirm the fistula, to visualise its site, course and involved organ, and to characterise the underlying disease. The traditional conventional radiographic studies provided limited cross-sectional information and are nowadays largely replaced by CT and MRI studies.Aiming to provide radiologists with an increased familiarity with VF, this pictorial paper summarises their clinical features, pathogenesis and therapeutic approach, and presents the appropriate CT and MRI acquisition and interpretation techniques that vary according to the anatomic site and termination of the fistula. The current role of state-of-the art CT and MRI is presented with examples regarding both entero- (involving the colon, rectum and anus) and urinary (connecting the bladder, distal ureter or urethra) VF. The resulting combined anatomic and functional cross-sectional information is crucial to allow a correct therapeutic choice and surgical planning.

Abstract
The Latzko transvaginal vesicovaginal fistula repair is a highly effective treatment for even complex fistulae. Our video demonstrates the Latzko repair technique and its application in a variety of circumstances that include fistula management concurrent with treatment of uterovaginal prolapse, after complex urologic surgery, and in the postpartum setting after urologic injury. The technique of the procedure varies only slightly in these diverse conditions. The basic steps begin with hydro-dissecting the epithelium from the underlying fascia surrounding the fistula tract, followed by denuding the epithelium within a circumscribing incision around the fistula. The fistula is then closed with a purse-string suture placed just outside the epithelialized tract. Next, several layers of imbricating sutures are placed to close the defect. Finally, the vaginal epithelium is closed.

Abstract
Background Although relatively rare, vesicovaginal fistula is the most common genitourinary fistula, causing a significant decrease in patients' quality of life. Location of fistula is major supratrigonal, with some cases located in the trigone and rarely below it. Disease treatment is surgical, and repair can be performed by several techniques, including robot-assisted. Case Presentation We present a case of a patient who developed an infratrigonal vesicovaginal fistula after treatment of a cervical cancer. The patient was submitted to robotic repair of the vesicovaginal fistula. Conclusion The use of robot-assisted laparoscopy is expanding over all areas of urology and its applicability to repair vesicovaginal fistulas brings good results.

Abstract
OBJECTIVES To report a large series of vesicovaginal fistula, and to assess the incidence of ureteric injury in association with vesicovaginal fistula. METHODS We retrospectively reviewed a prospective database of patients with vesicovaginal fistula referred to our center between 2004 and 2016. Data on patient demographics, fistula etiology, mode of repair, and any associated ureteric injury and its treatment were noted. RESULTS Overall, 116 patients (median age 49 years, range 23-88 years) were referred for management of vesicovaginal fistula during the study period. Four of these patients (3.4%) had associated ureteric injury, one of whom had bilateral injury. Ureteric obstruction alone was noted in two patients, ureterovaginal fistula alone in one patient, and bilateral ureteric obstruction and ureterovaginal fistula in one patient. All ureteric injuries were managed with simultaneous reimplantation into the bladder at the time of vesicovaginal fistula repair. Five patients had post-radiotherapy vesicovaginal fistula, and the remainder were post-surgical. Three patients with post-radiotherapy vesicovaginal fistula proceeded to primary diversion. CONCLUSIONS Ureteric injury is far less common than previously reported, occurring in <5% of patients presenting with vesicovaginal fistula. It can be successfully managed, and it remains the major indication for abdominal repair of vesicovaginal fistula.

Abstract
OBJECTIVE To analyze the patterns of presentation and management for urologic complications of obstetrics and gynecology in the form of genitourinary fistulas at a tertiary referral center and highlight the social issues associated with them. MATERIAL AND METHODS We conducted this retrospective study analyzing 311 patients with genitourinary fistulas after obstetric and gynecologic surgeries between January 2005 and January 2018. We recorded the patients' characteristics and area of residence and then analyzed the etiology, surgical management and success rates by grouping the patients into four types of genitourinary fistulas. The primary end point of success was patient being leak free. RESULTS Majority of patients (90.4%) were from rural areas. The distribution of genitourinary fistulas in descending order was vesicovaginal (79.7%), ureterovaginal (11.8%), urethrovaginal (10.2%) and vesicouterine fistulas (2.6%). The mean time to presentation was 25.80±48.69 days with a wide range of 10 days to 360 months. The most common etiology was obstructed labour (58.5%) followed by abdominal hysterectomy (32.7%). For vesicovaginal fistulas the route to be used for repair depended on surgeon's preference and both transabdominal and transvaginal routes had almost equal success rates. The success rate of laparoscopic vesicovaginal fistula repair was 89.4% and all (100%) laparoscopic ureteroneocystostomies were successful. CONCLUSION Genitourinary fistulas especially due to obstructed labour are still common in developing world showcasing the problem of inequitable distribution of healthcare. The surgical treatment approach depends on the surgeon's familiarity with the said procedure although versatility is required.

Abstract
BACKGROUND A vesicovaginal fistula is an abnormal fistulous tract extending between the bladder and the vagina that allows the continuous involuntary discharge of urine into the vaginal vault. In addition, the sequelae from these fistulae have a profound effect on the patients in view of their physical, psychological, and social dimensions. The treatment of vesicovaginal fistula is surgical in most cases and the choice of the repair technique is controversial. We evaluated the benefits of a laparoscopic approach in a patient with vesicovaginal fistulae. Here, we present our first experience using a simplified laparoscopic approach technique to repair vesicovaginal fistulae in our country. CASE PRESENTATION A 46-year-old Javanese woman presented with urinary incontinence following an abdominal hysterectomy 3 months earlier and received laparoscopic repair. A cystoscopy was performed to confirm the fistula orifice and a stent was inserted into the fistula tract from her bladder to her vagina. A tamponade was inserted into her vagina up to the vaginal apex, to be able to identify the vagina. She had adhesions; therefore, adhesiolysis was performed using a combination of sharp and blunt dissection to expose the vaginal stump and the superior aspect of her bladder. A simple cystotomy was performed and extended to include the fistulae site, and then the defect was repaired by using a running stitch. A second layer of closure was performed in an imbricating fashion with the same suture. The vagina defect was not closed separately but covered with an omental flap. This procedure takes approximately 2.5 hours; estimated blood loss was minimal and there were no intraoperative complications. She had no recurrent symptoms 6 months after surgery. CONCLUSION Our case report concludes that the simplified laparoscopic approach to vesicovaginal fistulae is a viable option for successful repair and that it reduces the size of bladder opening, causes minimal bleeding, and gives successful relief.
