Prostate spindle cell neoplasm associated with early voiding difficulty after transurethral resection of the prostate

Abstract

This report presents the case of 75-year-old men with spindle cell neoplasm. The patient underwent percutaneous nephrolithotomy and transurethral resection of the prostate (TURP) for renal stones and benign prostatic hyperplasia. One month postoperatively, the patient was able to void without any difficulty. Five months later, the patient experienced difficulty voiding and presented to the emergency room with severe pelvic pain. Computed tomography (CT) showed regrowth of the prostate mass into the posterior bladder and penile root. The prostate-specific antigen level remained constant at 1.14 ng/mL during the pre-and postoperative periods. Five months before the TURP operation, the patient’s CT scan showed a soft and mildly enlarged prostate with no protrusion into the bladder. Biopsy of the prostate, however, showed a protruding mass, indicative of a spindle cell neoplasm. The patient was subsequently treated with the chemotherapeutic drug adriamycin. Unfortunately, treatment was unsuccessful, and the patient died 18 months later.
