Uretero-vaginal fistula.

Six cases of uretero-vaginal fistula are presented. Five patients developed this complication after gynaecological surgery and one after Caesarian section. Constant urinary incontinence combined with normal voiding is typical of this lesion. Excretory urography revealed a stricture in the distal part of the ureter in 5 cases, while in one patient the urographic findings were normal. Accumulation of contrast medium in the vagina was seen on urography in 2 patients. Surgical correction is the treatment of choice, and all patients were successfully treated by resection of the distal part of the ureter with reimplantation of the ureter into the bladder.
