[Female urethral adenocarcinoma with urinary retention: a case report]

A 57-year-old woman presented with urinary retention. Computed tomography revealed a pelvic mass. Vaginal examination revealed an elastic-hard mass beneath the anterior vaginal wall. Intravenous pyelography demonstrated the filling defect of bladder. Magnetic resonance imaging revealed the mass that had invaded bladder neck at dorsal side of urethra. Pathological examination of transvaginal needle biopsy suggested well-differentiated adenocarcinoma. Total cystectomy and ileal conduct formation was performed. Pathological diagnosis was urethral adenocarcinoma. She had local recurrence at perineum at seven months after the operation, and tumor resection was performed. Five months after the operation, she had no evidence of recurrence.
