Background: Ectopic ureter is a condition when the ureter does not enter the bladder properly. The occurrence of the ectopic ureter is 1:2.000 - 1:4.000 in general population with gender ratio 6:1 in favour of females. More than 80% of cases of ectopic ureters are generally associated with complete duplication of the pelvic-ureteric system. Still, the ectopic ureter can also occur in a single pelvic-ureteric system, which is typically dysplastic or poorly functioning, such as in multicystic dysplastic kidney. This study aims to evaluate the current management of a single ectopic ureteral system with dysplastic multicystic kidneys at Sanglah General Hospital, Bali, Indonesia.
