Therapeutic transrenal occlusion of the ureter: solution of plug migration problem.

Vesicovaginal fistulas in three patients and a vesicocutaneous fistula in one patient were treated by percutaneous transrenal occlusion of the ureter with a commercially available silicone occluder (Angiomed, Karlsruhe, Germany) which was secured by means of histoacryl placed on top. Urinary flow was diverted by a permanent nephrostomy tube. We observed no complications (e.g., urinary tract infection, occluder migration, or recurrence of urine discharge) at an average follow-up period of 9.1 months.
