Abstract
The author has collected 16 cases of ectopic ureter in girls. In one case, the ectopy was bilateral and was associated with a bilateral triplication. The malformation is detected at a very early age: 5 times out of 16 in children less than 3 years old. The clinical investigation under general anesthesia is of prime importance in the diagnosis in children. In half of the cases, the upper pyelon was dysplasic. If it is not dysplasic, it suffers from interstitial nephritis. In 12 cases, the incontinence was cured by hemi-nephro-ureterectomy. In 4 cases, the condition of the upper pyelon allowed a conservative surgery: the author advises the vesical reimplantation of the only pathological ureter; this process has been successful 4 times in 4 children operated.
