Ureterocele prolapse eliciting unusual patient behavior to control intermittent voiding

Ureterocele prolapse, an unusual but distinctive finding, may cause voiding difficulty. A 6-year-old male patient was referred to our hospital after his mother discovered that he tapped his lower abdomen when his urinary stream was interrupted during voiding. Voiding cystourethrography indicated a ureterocele prolapse causing the intermittency of voiding; therefore, transvesicoscopic ureteral reimplantation with ureterocelectomy was performed and the voiding consequently improved. However, this condition would not have been diagnosed had the unusual voiding behavior gone unnoticed. Therefore, diagnosing congenital bladder obstructions could be challenging if a patient adapts to a voiding difficulty.
