The prevalence of ureteral ectopia is low and it is usually associated with pyeloureteral duplication. In these cases, incontinence is frequent. We present the cases of five female patients treated in our hospital for urinary incontinence due to ureteral ectopia and duplicity. The ectopic ureter reached the uterus in three patients and the vagina in the remaining two. The treatment chosen was heminephroureterectomy due to the presence of hypofunctional or dysplastic segments. Incontinence disappeared after surgery.
