Ureterocele with embedded stone suggesting a diagnosis of bladder tumor: beware of the diagnostic trap! (case report and literature review).

Ureterocele is a congenital urinary malformation resulting in pseudo-cystic dilation of the terminal ureter under the mucosa. We present the case of a 47-year-old patient who presents with irritative symptoms of the lower urinary tract with hematuria. Initial imaging suggested a bladder tumor with a bladder stone, before correcting the diagnosis of ureterocele with embedded stone by cystoscopy. Treatment included endoscopic ureterocelotomy with laser stone fragmentation.
