Frequency of Success in Surgery of Vesicovaginal Fistula by Layered Closure with Graft Repair

Introduction: Vesicovaginal fistulae is abnormal communication between bladder and vagina that cause continous dribling of urine. It is physically, mentally and socially distressing condition. There are various approaches for surgeries of these urogenital fistulae with different success-rate that depend upon the experience of surgeon and surgical procedures. This study can help us to estimate the success rate of layered repair with graft in vaginal route to make stragedy to adopted in severe patient. Objective: To determine frequency of success in surgery on vesic-ovaginal fistulae by layered closured with graft repair procedures among patients admitted in Isra University. Setting: Obstetrics & Gynecology department in Isra university hospital Duration: 6 months from 10.2.2014 to 10.8.2014 Study Design: Case series Subject and methods: A total of 100 patients after having surgery for vesicovaginal fistula by layered closure with graft repair was included in this study. History and examination of all subjects were taken. The follow up visit was planned after 3 weeks of surgery. All women was questioned for recurrence of continuous urinary leakage and that without such symptoms proved by absence of leakage on methylene blue dye test was labeled as ‘success’. Results: - Frequency of success in surgery on vesic-ovaginal fistulae by layered closured with graft repair procedures was observed in 88% cases. Conclusion: The success rate of VVF repair by layered closured with graft repair procedures is high. It is concluded that obstetric urogenital fistula is a preventable condition.

Postradiation genitourinary fistulae: retrospective study

Introduction. Radiation therapy of the pelvic organs, used to treat malignant neoplasms, is the main cause of urogenital fistula formation (UGF). The widespread use of radiation therapy in the treatment of malignant neoplasms of the pelvic organs has led to an increase in the number of patients with radiation injuries. The study of the prevalence, characteristics and long-term results of surgical treatment of fistulas are of great interest. Materials and methods. There are 76 patients with postradial fistulae received treatment in our Clinic Department of Urology of A.E. Evdokimov Moscow State University of Medicine and Dentistry for the last 6 years from 2012 – through 2018; 49 patients (64.5%) were operated on. The majority of the patients were suffering from vesicovaginal fistula 48.7% (37 people). Transvaginal approach was used in 35 cases (71.4%); abdominal approach was in 7 cases (14.3%); laparoscopic approach was in 3 cases (6.1%); robotic approach took place in 2 cases (4.1%); combined – one case (2%), percutaneous puncture nephrostomy – 1 case (2%). The various flaps technique took place in 40.8% of cases (20/49). Results. In total, radiation indced fistula closed in 35 out of 49 patients successfully. As a result, overall efficiency was 71%. The presented data has included our experience over the past 6 years, which is limited by the standardization of treatment and the lack of some data. Conclusions. Closing the fistula can be performed in several stages: by reducing the size of the fistula and giving patients more time to recover.

Vesico-Salpingo Fistula Masquerading as Hydrosalpinx with Neurogenic Bladder - An Interesting Case Report

A fistula is an abnormal connection between two luminal structures of different epithelium. The majority of urological fistulas in developed countries are consequences of iatrogenic injury most commonly laparoscopic hysterectomies, or from radiotherapy in the treatment of pelvic cancers.1 Contrary to this, most obstetric fistulas in developing countries result from obstructed labour during childbirth.2 Common factors that contribute to obstructed labour in developing countries are delayed presentation after trial labour at home, cephalopelvic disproportion and poor nutrition. Due to prolonged compression by head on the pelvic tissues there happens ischemic necrosis of vagina, bladder neck, and urethra3 called obstructed labour complex. Necrosis and fibrotic healing lead to fistula formation with adjacent structures. The vesicovaginal fistula was the most frequent one (78 %) and the common site involved was trigone (51 %) and based on the level it could be a high or low fistula. Others are vesicouterine fistula, vesicourethral fistula, vesicoureteral fistula and rarely vesico-salpingo fistula. During the acute phase of fistula, tissue oedema, hypovascularity, infection, and nonviable tissue hinder proper tissue healing and hence delayed repair is done after 3 months. Recent literature advises early repair for simple fistulas to reduce patient morbidity and delayed repair of complex fistula, multiple fistulas, infected fistulas, post-radiotherapy, fistula due to foreign bodies, immunocompromised patients, hypoproteinaemia patients, urosepsis patients. 4 Fistula repair is preceded by contrast evaluation of ureter and bladder by CT –IVU and cystogram or MRI followed by cystoscopy or retrograde pyelography. Apart from fistula closure, bilateral ureteric implantation may be needed if ureters are close to the fistula. 5 Abdominal hysterectomy is done in uterovesical fistulas. Huge fistulas close to the bladder neck cannot be repaired without compromising continence hence bladder neck closure is done with the Mitrofanoff procedure. 6 A vesico-salpingo fistula is an abnormal epithelial-lined communication between the urinary bladder and the fallopian tube. This rare type of urogenital fistula has only 7 previously published cases in the literature.

Youssef syndrome with a summary of management options

Vesicouterine fistula is one of the rare varieties of urogenital fistula. Type I urogenital fistula or Youssef syndrome is characterised by menouria, amenorrhoea and urinary continence and it mostly follows lower segment caesarean delivery. There are only scattered case reports to help guide diagnostic and therapeutic options for this condition. These patients mostly need a combination of diagnostic modalities to confirm the diagnosis. Here, we present one such case of para 4 live 4 with classical symptoms of Youssef syndrome following a laparotomy for uterine rupture repair. CT urography confirmed the diagnosis and cystoscopy helped localise the exact location. Transabdominal fistula excision and repair was done. The paper also presents a summary of diagnostic and therapeutic options for this condition as reported in previous case reports for easy reference for practising gynaecologists and urologists.

A Rare Case of Vasculitis ANCA of Bladder and Urethra Providing to Vesicovaginal Fistula and Early Recurrence of Illness

Introduction: Vasculitis of the bladder and urethra is a rare disease. Its presentation, as a pelvis tumor, indicates the cancerous nature of the lesion. An incorrect diagnosis can result in the removal of the bladder. Case Presentation: We described a 56-year-old woman (born in 1964) with a vesicovaginal fistula, which arose from vasculitis ANCA. Establishing the correct diagnosis was a long and complicated process. During diagnosis, a urogenital fistula was created due to the deepening of inflammatory necrotic lesions. Remission was achieved by pharmacological treatment. As a result, fistula surgical treatment became possible. An unexpected relapse of vasculitis was diagnosed based on the bladder emptying symptoms. Repeating the treatment resulted in a complete response. Eventually, we obtained a cure of regional vasculitis while maintaining the bladder and urethra, which translated into an increased quality of life for the patient. Conclusions: Correct diagnosis before surgery is of crucial importance. Combined pharmacology and surgery prevents removal of the bladder. Careful observation of symptoms allowed for the early detection of recurrent vasculitis.

Risk factors for perioperative blood transfusions after urogenital fistula repair in Uganda: a retrospective cohort study

Objective: To determine the incidence of and risk factors for perioperative blood transfusions after urogenital fistula repairs in Uganda. Design: A retrospective cohort study. Setting: A community hospital in Masaka, Uganda. Population: Women who underwent fistula repair at the Kitovu Hospital between 2013 and 2019. Methods: Retrospective review of demographics, and clinical perioperative characteristics of patients surgically treated for urogenital fistula. Patient characteristics were compared between those who did and did not require a blood transfusion. Main Outcome Measures: need for perioperative blood transfusion, risk factors Results: 546 patients treated for urogenital fistulas were included in this study. The median age was 31.1 ± 13.2. A vaginal surgical approach was used in the majority of patients (84.6%). Complications occurred in 3.5% of surgical repairs, and the incidence of blood transfusions was 6.2%. In multivariable analyses, women with fistula repairs approached abdominally were 4.3 (95% CI: 1.85–10.00) times more likely to require transfusions than vaginal operations. A borderline association was observed between timing of repair and perioperative transfusions such that patients who underwent repair after three months from the time of developing the fistula were at lower risk of perioperative transfusions (aOR: 0.48, 95% CI: 0.22–1.04). Conclusions: The incidence of blood transfusions among urogenital fistula repairs in our population is twice that of developed nations. An abdominal surgical approach to urogenital fistula is a significant risk factor for perioperative blood transfusions. Timing of repair may warrant further study.
