Prognostic factors of recurrence after vesicovaginal fistula repair

PURPOSE: We evaluate the prognostic factors of recurrence in patients after the surgical repair of vesicovaginal fistula. MATERIALS AND METHODS: From 1985 to 2002, 73 women with vesicovaginal fistula underwent late (> 3 months) surgical repair. A multivariate analysis of the data was performed with the EPI-INFO software. All P-values were two-sided, with odds ratio and 95% confidence intervals. RESULTS: A total number of 73 patients underwent 97 procedures with a mean rate of 1.38 procedures/patient. The overall surgical success rate was 86.7%. Multivariate analysis demonstrated that recurrence was statistically significant for multiple fistulas (single vs two or more), fistula size (>10 mm), fistula type (Type I vs Type II), fistula etiology (obstetrical vs non-obstetrical) and the presence of urinary tract infection before the repair. Recurrence risk was fivefold higher for both the size and the type of the fistula, threefold higher for obstetrical etiology and 4.5-fold higher for multiple fistula. The interposition of flaps was a protective factor for recurrent cases. The surgical approach was not a significant prognostic factor of recurrence. CONCLUSION: Successful closure of a vesicovaginal fistula requires an accurate and a timely repair using procedures that exploit basic surgical principles. Multiple fistula, size and type of the fistula, and obstetrical etiology were the recurrence risk factors. We recommend in all patients with multiple risk factors for recurrence, the interposition of flaps.     

Laparoscopic repair of vesicovaginal fistula

PURPOSE: Vesicovaginal fistula may be a complication of urogynecologic surgery. We describe the technique of laparoscopic repair of vesicovaginal fistula as performed at our 2 institutions. MATERIALS AND METHODS: Since August 1998 laparoscopic repair of vesicovaginal fistula was performed in 15 select patients who had clear indications to undergo surgical treatment through an abdominal approach. Hysterectomy had previously been performed in 14 patients (93%). Conservative treatment was initially attempted for more than 2 months in all cases. Four patients had undergone a previous surgical fistula closure attempt with unsuccessful results. Our technique involved cystoscopy, catheterization of the vesicovaginal fistula, laparoscopic cystotomy, opening and excision of the fistulous tract, dissection of the bladder from the vagina, cystotomy closure and colpotomy with interposition of a flap of healthy tissue. Demographic as well as perioperative and outcome data were recorded. RESULTS: Average patient age was 38 years. None of the cases required open conversion. Mean operative time was 170 minutes (range 140 to 240). Mean hospital stay was 3 days (range 2 to 5). The mean duration of bladder catheterization was 10.4 days (range 9 to 15) At a mean followup of 26.2 months (range 3 to 60) 14 patients (93%) were cured. CONCLUSIONS: We believe that laparoscopic repair of vesicovaginal fistula is a feasible and efficacious minimally invasive approach for the management of this entity.

Congenital vesicovaginal fistula

Congenital vesicovaginal fistula is a very rare entity, the etiology of which has not been clearly elucidated because pathologic features have not been mentioned in previous reports. The case of a 4-year-old girl having incontinence resulting from a congenital vesicovaginal fistula joining with the left ectopic ureter from the hypoplastic kidney is described. This is thought to be the first presentation of congenital vesicovaginal fistula joining with ectopic ureter. A microscopic examination revealed the fistula consisting of transitional cell epithelium, suggesting an abnormal fusion of the ureteral bud and caudal end of the müllerian duct with the urogenital sinus.     

Surgical repair of a vesicovaginal fistula guided by a black braided silk suture line

The purpose of the study was to evaluate the effect of the identification of the margins of a vesicovaginal fistula (VVF) during its repair by passing a black braided silk suture line through the fistula. During the repair of a VVF, a suture line was placed through the fistula. By passing the suture line from the vagina through the fistula tract into the bladder and hence to the outside through the urethral meatus, the circumference of the VVF opening can be easily identified after dissection and excision of the vaginal wall around the fistula opening. There were four VVF patients who underwent a modified Latzko procedure using the thread to guide surgical repair. The operation times and blood loss were 45–90 min and no more than 50 ml, respectively. This trick provides adequate identification of the fistula tract, thus permitting safe and easy fistula repair for a narrow, deep, or atrophic vagina.     

Early laparoscopic repair for supratrigonal vesicovaginal fistula

Laparoscopic repair of supratrigonal vesicovaginal fistula is less morbid and equally effective compared to open repair. This approach is advisable when transvaginal repair is difficult.     

Retropubic repair of genitourinary fistula using a free supporting graft

OBJECTIVE: To report the repair of genitourinary fistulae using a retropubic extraperitoneal transvesical approach using a support graft (free graft) from the anterior abdominal wall fat. PATIENTS AND METHODS: In all, 26 women with genitourinary fistulae (25 with vesicovaginal and one uterovesical) were operated using the free graft method. RESULTS: All patients had no leakage after surgery; while 15 developed urgency three had recurrent urinary tract infection and one developed a small bladder capacity. CONCLUSION: This operation has the advantages of a short operative duration, an easy technique and fewer postoperative complications with a high success rate.     

Congenital vesicovaginal fistula with transverse vaginal septum and ectopic ureter opening in proximal vagina: case report and brief review

Congenital vesicovaginal fistula is an extreme rarity. We report on a case of a 22-year-old lady who presented with menouria and infertility. On evaluation, she was found to have congenital vesicovaginal fistula, a nonfunctioning right kidney with ectopic ureter and transverse vaginal septum. Abdominal repair of the fistula, right nephroureterectomy, and excision of the vaginal septum was performed.     

Laparoscopic repair of vesicovaginal fistula

Introduction In developed countries, the majority of vesicovaginal fistulas develop after gynaecologic surgery, with abdominal hysterectomy accounting for 90% of cases. Several techniques are available for repairing the fistulas. Abdominal approaches give good results even for difficult posterior located fistulas, but are associated with increased morbidity compared with the transvaginal approach. We performed a laparoscopic repair to minimize the surgical morbidity of the transabdominal approach. Methods A 44-year-old female presented with vesicovaginal fistula after abdominal hysterectomy. After a failed trial of conservative treatment with catheter drainage, a transperitoneal laparoscopic repair was performed. Cystoscopy was performed intially to confirm the fistula location and for bilateral ureteric catheterization. A 4-port technique was performed with the patient in the Trendelenburg position with her legs in lithotomy position. Without opening the bladder, the fistula tract was excised with separation of the bladder from the anterior vagina wall. Both the bladder and vagina walls were then closed separately using intracorporeal suturing with an interpositional omentum. Results The operation was uncomplicated. Total operative time was 260 min. Normal diet was resumed on day 1 and patient was discharged on the same day with an indwelling catheter. A cystogram performed 3 weeks post surgery showed resolution of the fistula. Conclusions Laparoscopic repair of vesicovaginal fistula without opening the bladder and using intracorporeal suturing and omentum interpositioning is feasible in selected patients.     

Latzko repair for vesicovaginal fistula revisited in the era of minimal-access surgery

Latzko repair is a technique described for repair of post-hysterectomy supratrigonal vesicovaginal fistulas (VVF) and is often practised by gynecologists, but it has not figured in the armamentarium of urologists the world over. Recently urologists have taken to laparoscopic repair of such fistula but laparoscopic repair is technically demanding with a steep learning curve. We reviewed our experience with the technique of Latzko repair. The study is a review of 10 patients operated by this technique between June 2000 and May 2005, with age ranging from 33 to 55 years (average 39 years). Fistula size ranged from 2 mm to 1 cm. There was no recurrence or sexual dysfunction due to shortening of vaginal length. The results were comparable with laparoscopic VVF repair in terms of morbidity, operative time, blood loss, and patient discomfort. Also, the learning curve involved is minimal. Thus this technique deserves wider adoption by the urological community and should be a benchmark for comparison with laparoscopic repair of VVF rather than the abdominal approach. Bearing in mind the simplicity of the procedure, urologists should feel encouraged to adopt this excellent age-old technique that has stood the test of time rather than exploring more-complex operations such as laparoscopic VVF repair and transurethral suture cystorrhaphy.     

Recognition and management of patients with high-risk vesicovaginal fistulas: Implications for teaching and research

Vesicovaginal fistulas (VVFs) occurring as a result of obstetric trauma are a vast problem in Nigeria and Ghana, where at least 20 000 women await repair, and fewer than 50 physicians have the necessary expertise. Through a series of conferences those VVFs that are at high risk and those at low-risk for repair failure, were identified. A clinic was established where repair of low-risk VVFs was done on an ongoing basis in a remote region of Ghana. A visiting surgical team was utilized to repair the difficult, or high-risk, VVFs, which included 4–6 cm VVFs (3), recurrent VVF (1), combined VVF and RVF (rectovaginal fistula), a large 5 cm juxtacervical VVF (1), and a vesicouterine fistula (1). Management of these patients and others with VVF repair complications is discussed.

New trends in the management of colonic trauma

BACKGROUND: The management of colon trauma seems to have swung from the "diversion dogma" to a more liberal use of primary repair. However, there are still debatable issues, regarding the management of destructive injuries of the left colon. METHODS: A review of the current literature on the management of colon trauma was performed using PubMed, with secondary references obtained from key articles. CONCLUSION: There is strong evidence from prospective randomised trials that the vast majority of colonic injuries can be safely managed by primary repair. It seems, however, that there is a limited role for colostomy, particularly in high-risk patients with destructive injuries of the left colon. The final decision should be based on available scientific evidence in combination with personal experience and clinical judgement on the given patient.
