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

## TL;DR

A patient's bladder tumor was misdiagnosed as a ureterocele with a stone, highlighting the importance of accurate diagnosis.

## Contribution

This case report highlights the diagnostic challenge of ureterocele mimicking bladder tumors.

## Key findings

- Initial imaging misdiagnosed ureterocele as a bladder tumor.
- Cystoscopy confirmed the correct diagnosis of ureterocele with an embedded stone.
- Endoscopic treatment successfully resolved the condition.

## Abstract

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.
