title: [Simple orthotopic ureteroceles in children].
abstract: A simple orthotopic ureterocele is a ureterocele developed on the terminal portion of a single ureter normally implanted into the bladder. This type of ureterocele is often bilateral and is less frequently observed in children than heterotopic ureteroceles complicating total duplication (27%-73%). The authors report six such cases, review their classical radiological signs, and emphasize three unusual findings:--A simple orthotopic ureterocele complicated by the presence of stones. --A prolapse of a ureterocele into the posterior urethra in a boy, with subsequent dysuria. --A simple orthotopic ureterocele in a blind ureter from a polycystic kidney, with a contralateral primary obstructive mega-ureter.
