Abstract/OtherAbstract:	The aims of this study were to demonstrate a case of bilateral intravesical ureterocele associated with megacystis and mega-ureters, unilateral partial duplication of the ureter and unilateral segmental renal dysplasia of the upper pole and an accessory spleen and to propose an addition of the new variant to the classification of ureteroceles. A perinatal necropsy was conducted on the 21-week fetus by employing the Rokitansky procedure with evisceration performed in blocks. The autopsy revealed the aforementioned abnormalities without cardiac or neural anomalies. The amniocentesis report was normal. Ureterocele is a saccular expansion of the distal ureter. It is most commonly observed in females and children and usually affects the upper moiety of a complete pyeloureteral duplication. Four types of ureteroceles are described: (A) ureterocele with single ureter (10%); (B) ureterocele with total duplication and intravesical development (10%); (C) ureterocele with total duplication and extravesical development (62%); and (D) ureterocele with ectopic ureter (3%). One case in a new born with bilateral intravesical ureterocele associated with hydrouretero-nephrosis and hyperechogenic spots in kidneys has been reported, but bilateral intravesical ureterocele with unilateral incomplete pyeloureteral duplication has never been described in the literature.
