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.
单纯原位输尿管囊肿是指在正常植入膀胱的单一输尿管末端形成的输尿管囊肿。这种类型的输尿管囊肿常为双侧性，在儿童中比合并完全重复畸形的异位输尿管囊肿（27%-73%）少见。作者报告了6例此类病例，回顾其典型的放射学征象，并强调了三个不寻常的发现：——合并结石的单纯原位输尿管囊肿。——一名男孩的输尿管囊肿脱垂至后尿道，随后出现排尿困难。——多囊肾盲端输尿管中的单纯原位输尿管囊肿，对侧为原发性梗阻性巨输尿管。
