Ureterocele is a cystic dilatation of submucosal distal ureter. This condition presents an incidence about 1/5000 to 1/12000 and is higher in infants and young children. It is more frequent in women. However, the presentation as urethral prolapse is extremely rare, appearing in only 5% of cases. We present a case with recurrent prolapsed ureterocele, including clinical presentation, images, and management.

A 12-year-old girl presented with occasional protruding mass from genital area which could be reduced spontaneously or with manual push. However, the protruding mass from genital area during defecation was noted and could not be pushed back. Accompany symptoms including pain, urine retention, and bleeding. The patient was then brought to our emergency room. Prolapsed ureterocele was diagnosed after gynecologic ultrasound which showed right hydronephrosis and hydroureter. The transurethral unroofing operation was performed after reduction of prolapsed ureterocele. The symptoms subsided after the operation. Currently, the patient is still following-up in our outpatient department.
