[Vesicovaginal fistula which arose postoperatively after removal of the ureter by the intussusception method for renal pelvic tumor: a case report].

A 64-year-old woman underwent right nephroureterectomy of the ureter by the intussusception method under the diagnosis of right renal pelvic tumor in December 2001. Stress incontinence appeared postoperatively, and though conservative treatment was performed, it did not improve. The result of the pad-weighting test was 56 g indicating serious incontinence. In chain cystography, contrast media from the posterior wall of the urinary bladder to the vagina leaked out by the lateral view, and in cystoscopy, a fistula of about 2 mm in diameter was recognized in the right ureteral orifice trace. Under the diagnosis of vesicovaginal fistula, we performed transvaginal repair of the vesicovaginal fistula in November 2003. The urethral catheter was removed on the 14th postoperative day. After removal of the urethral catheter, urge incontinence was recognized, but it improved gradually. The recurrence of fistula and tumor has not been recognized at present.
