Congenital urethral polyps are an uncommon cause of urethral obstruction in male children. The diagnosis is obtained at voiding cystography by demonstrating a filling defect which (typically) moves during micturition. A small polypoid mass with a stalk arising from the region of the verumontanum was observed by sonography in one such patient. We believe sonographic findings may be considered specific of this condition.
Four cases of blind ureteric bud are presented. This unusual abnormality is the result of abortive development of a normal bud or, more frequently, of an accessory bud brought into being by abnormal or premature division of the primary bud. - The disputed relationship between this abnormality and congenital ureteral and vescical diverticula is discussed. It is felt that the embryogenetic and anatomopathological evidence justifies the inclusion of some of the latter within the more extensive term "blind ureteric bud".
