[Pseudo-ureteroceles resulting from the impression of a loop of a megaureter with an ectopic subvesical orifice].
The authors report 3 rare cases of pseudo-ureteroceles corresponding to a vesical imprint of an ectopic extra-vesical megaureter. When an ectopic extra-vesical ureter follows a sharp juxta-vesical buckle, it can give a deep imprint on the bladder and look similar to an ureterocele. I.V.P. and U.S. can be as misleading since the appearance of this type of megaureter and ureterocele can be similar, and differential diagnosis can be difficult. Such situations are rare. In a ten years of pediatric urologic practice, the authors who have investigated 51 ureteroceles and 26 extravesical ectopic ureters, have only observed 3 children with this lesion. These 3 cases corresponded to two simple ureters, in a 3 year old boy and in a 2.5 year old girl, and one upper ureter of a complete duplex system in a neonate baby girl with antenatal discovery. The clinical, radiological, sonographical and endoscopic clues to the diagnosis are discussed and illustrated.
