Abstract: | Acquired infundibular stenosis is an unusual complication resulting in pancalyceal obstruction. We have cared for 6 patients with acquired infundibular stenosis not associated with tuberculosis. All patients had urinary diversion with ileal conduits for a minimum of eleven years and documented ileal-ureteral reflux and chronic urinary tract infections. The clinical, radiographic, and pathologic characteristics of this syndrome are described and therapeutic guidelines suggested. |
