Gardner's syndrome (GS) is complicated by abdominal desmoid tumors in
approximately 8% of cases. We describe two cases of ureteral obstructi
on and fistulization due to rapidly enlarging desmoid tumors. Initial
management consisted of placement of ureteral stents to provide urine
drainage from the kidney as well as from the collection in the cavitie
s within the desmoid tumors. Copyright 1997 by Elsevier Science Inc.
