Abstract
Ureterocele is rare urinary malformation. We reported a 12-month-old girl case with a prolapsed ectopic ureterocele in the vulva. Urinary catheterization was used as an emergency treatment to minimize the ureterocele. The patient later benefited from an upper polar hemi-nephrectomy, which helped to resolve the issue partially. She sought treatment for the prolapse again a Three month later, this time ureterecelectomy with ureteral reimplantation was employed. The non-consensual management of this malformation must be initiated as soon as possible to prevent complications. The first treatment goal was to decompress the prolapsed ureterocele and remove it endoscopically.
