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 uretero-cele associated with bilateral uropathy.
