Adenocarcinoma of the bladder is usually managed by radical cystectomy. However, recent literature shows that internal genital organ-preserving radical cystectomy is feasible in selected cases in order to get a better impact on patient's psychology, sexuality and potential fertility. Here, we report a 32-year-old woman with adenocarcinoma of the bladder who was managed with internal genital organ-preserving radical cystectomy. The patient was never had any child and the radiologic examination (MRI) showed no involvement of internal genitalia organ. This procedure aims to maintain fertility potential of the patient. Intraoperatively, no adhesion was found between the tumor and internal genitalia organ. The internal genitalia organ was successfully preserved during the radical cystectomy
