Transrenal ureteral occlusion with the use of microcoils in five patients with ureterovaginal fistulas.
BACKGROUND
To evaluate the feasibility and efficacy of transrenal ureteral occlusion with microcoils in patients with ureterovaginal fistulas


METHODS
Five women (median age 44 years, range 26-51 years) with ureterovaginal fistulas were treated by transrenal ureteral occlusion with microcoils. The underlying diseases were uterine fibroids (n = 3), a primitive neuroectodermal tumor of the uterine cervix (n = 1), and an ovarian cancer (n = 1). Microcoils with or without gelatin sponges, were placed antegradely through a percutaneous nephrostomy (PCN). A PCN tube was then placed to provide an external diversion


RESULTS
The transrenal ureteral occlusion was technically successfully in all patients. Complete or near complete (<1 pad/day) dryness was obtained in all patients within 3 days. No complications other than a slight proximal migration of the microcoils in two patients occurred. The PCN tubes were removed in four of the five patients during the follow-up period with the subsequent procedures: antegrade ureteral stent placement, patent normal ureter, an ureteroneocystostomy and a laparoscopic end-to-end anastomosis of the ureter


CONCLUSIONS
Transrenal ureteral occlusion with microcoils with or without gelatin sponges is a safe and reliable method for the management of patients with ureterovaginal fistulas.
