Vascular polyps of ureter associated with megacalycosis and nephrolithiasis

Multiple benign vascular polyps of the ureter are rare, and the associated congenital megacalycosis and nephrolithiasis are very uncommon. Herein we report a case with vascular polyps of the right ureteropelvic junction dissociated with extensive hydronephrosis which was considered to be megacalycosis. Clinical features and treatment modalities are reviewed.
