Management Of Ureterovaginal Fistula Research Articles

Uretero-vaginal fistulas - clinical presentation, treatment and literature overview.

A uretero-vaginal fistula (UVF) describes an abnormal connection between the ureter and vagina causing urinary incontinence, frequent infection, and discomfort. Although UVF might be diagnosed after vaginal delivery, infertility treatment or pelvic radiation therapy, gynecological operations, especially total abdominal hysterectomy, remain the leading cause of ureteral injury and formation of UVF. Traditional ureteroneocystostomy was usually the treatment of choice in patients with UVF. Nevertheless, it is now frequently replaced by less invasive endoscopic and percutaneous procedures which are also highly effective and feasible. That is why, ureteral stenting became the first-line treatment in uncomplicated UVF. The aim of this review is to present clinical presentation of UVF and to assess the current state of knowledge about the diagnosis and management of uretero-vaginal fistula with special interest on minimally-invasive methods.

Ureterovaginal fistulae

Ureterovaginal fistulae are pathological communications between the ureter and the vagina; it commonly occur as a rare but serious sequela of unrecognized distal ureteral injuries during pelvic operations. Patients may present symptoms as leakage of urine from the vagina, flank pain and fever; in some cases it could be possible also the loss of renal function. The purpose of this study is to review the articles from 1991 to 2014 to evaluate the most correct diagnostic procedures and endourological and surgical techniques used in the management of ureterovaginal fistula. Nowadays computered tomography and retrograde pielography are the most commonly diagnostic modalities used to identify fistulous tract and to describe its anatomical position. The major of ureterovaginal fistulae can be successfully managed by conservative methods. Modern endourological treatment will result in resolution of a ureterovaginal fistula if retrograde or anterograde passage of a suitable internal stent is feasible. When stenting failed or in complicated cases, ureteral reimplantation is necessary. Ureteroneocystostomy, psoas hitch and Boari flap are three different possible surgical techniques used to realized an ureteral reimplantation. Both open and mini invasive (laparoscopy and robot assisted) surgical approach have proved successful.

Ureterovaginal fistula: a case series

We describe the presentation, diagnosis, and management of ureterovaginal fistula over a 7-year period at a tertiary care center. A retrospective review of ureterovaginal fistula cases between 2003 and 2011 was performed. Demographic information, antecedent event, symptoms, diagnostic modalities, and management strategies were reviewed. Nineteen ureterovaginal fistulas were identified during the 7-year study period. One fistula followed a repeat cesarean section and 18 fistulas followed a hysterectomy (9 total abdominal, 6 total laparoscopic, 3 vaginal hysterectomies). Ureteral injuries were not recognized in any of the patients at the time of index surgery. Computed tomography (CT) urography was the most commonly utilized diagnostic modality (58%). Primary non-surgical management with ureteral stents was attempted and successful in 5 out of 7 cases (71%). There were 14 total surgical repairs, including 2 cases in which stents were successfully placed, but the fistula persisted, and 6 additional cases where attempted stent placement failed. Surgical repair consisted of 10 ureteroneocystostomies performed via laparotomy and 4 performed laparoscopically, 3 of which were robotically assisted. Despite being uncommon, ureterovaginal fistula should remain in the differential diagnosis of new post-operative urinary incontinence after gynecological surgery. Conservative management with ureteral stent appears to be the best initial approach in selected patients, with a success rate of 71%. Minimally invasive approaches to performing ureteroneocystostomy have high success rates, comparable to those of open surgical repair.

Diagnosis and Management of Ureterovaginal Fistula in a Resource-Constrained Setting: Experience at a District Hospital in Northern Nigeria

During 2007 we were invited at different times to review and manage four women with ureterovaginal fistula following caesarean section performed in different rural hospitals. We describe our experience of a simple technique of diagnosis and management of these indigent patients in a resource-constrained hospital. The condition was diagnosed by the three-swab test in all four patients, and abdominopelvic ultrasound was employed to help find the ureter involved. Transvesical ureteral implantation with a stent was carried out. Stent was removed after 2 weeks. All four patients were dry. Amidst the complexity of and sophistication of modern health care, it is important to remind ourselves of the common occurrence of this distressing condition following caesarean section and the use of a well known simple diagnostic technique and subsequent management in resource-poor communities.
