[A case of ureterocele with ureteral stone and bladder tumor]

A case of ureterocele with ureteral stone and bladder tumor is reported. The patient, a 35-year-old man, presented with the complaint of terminal miction pain. IVP revealed the cobra-head appearances of a left-sided ureterocele, ureteral stone and hydroureter. The stone in the ureterocele and the tumor arising from the ureterocele were confirmed by cystoscopic examination. Transurethral biopsy was carried out and followed cystolithotomy, partial cystectomy, partial ureterectomy and ureteroneocystostomy. Histopathological examination of surgical specimens revealed the same feature of transitional cell carcinoma developed from the ureterocele.
