Ureteric obstruction occurs in about 1% of cases undergoing endoscopic treatment of vesicoureteric reflux (VUR). It usually develops shortly after treatment. We report on a case of obstruction occurring 1 year after subureteric injection of calcium hydroxyapatite. Obstruction was progressive and eventually required open ureteric reimplantation. Ureteric obstruction can occur also in the long-term after endoscopic treatment of VUR and even in the absence of symptoms. Although it is so rare as to make long-term follow-up of all treated cases cost ineffective, physicians should be aware of such complications, especially while testing new bulking agents.
