Percutaneous treatment of Fraley syndrome

OBJECTIVE: A case of upper calyx obstruction of the left kidney from an artery encroaching on the infundibulum is described. Treatment was by percutaneous insertion of a prosthesis. The results show the usefulness of the percutaneous approach in the treatment of this condition. METHODS: A Palmaz prosthesis was inserted into the obstructed infundibulum through a nephrostomy. Intravenous urography was performed immediately postoperatively and at 3, 6 and 12 months. RESULTS: No complications were observed postoperatively. At one-year follow-up the patient is asymptomatic and the urographic controls show improvement. CONCLUSIONS: Percutaneous insertion of a prosthesis in the treatment of infundibular stenosis had achieved good results in the case described herein, although a larger series and long-term follow-up are required to determine the usefulness of this approach.
