Prolapsing ureterocele in two infant boys

Ureterocele prolapse is a rare complication that obstructs the bladder outlet. This disease rarely presents in infant boys. In this case report, we present two 2.5 and 5-month-old infant boys with suspected posterior urethral valve diagnosis. Sonography demonstrated significant bilateral hydroureteronephrosis and unilateral interavesical ureterocele in both our patients. Voiding cystourethrography showed a filling defect in the posterior urethra associated with severe unilateral reflux. The diagnosis of prolapsing ureterocele should be considered whenever there is a ureterocele associated with bilateral uropathy
