A case of ectopic ureterocele is reported. A 2-year-old girl was admitted for recurrent episode of urinary tract infection associated with fever. IVP showed bilateral duplex kidney, although no excretion of dye was noted from the right upper kidney. IVP also revealed a large filling defect at the bladder neck which was diagnosed as ureterocele by cystoscopy. Cystography demonstrated VUR to the right lower kidney. A complete duplication of ureter with ectopic ureterocele on the right, and incomplete duplication of ureter on the left were found at operation. She underwent complete removal of the ectopic ureterocele and reimplantation of the right two ureters. Her postoperative course was uneventful, post-operative IVP revealed improvement of pyelography of the right lower kidney and cystography revealed no VUR.
