[A case of giant vesical diverticulum with malignant neoplasm].
We experienced a case of giant vesical diverticulum with a malignant neoplasm in which the preoperative diagnosis was difficult. It simultaneously occurred with a vesical tumor. The patient, a 68-year-old man, visited our hospital complaining of pollakisuria, nycturia and microscopic hematuria. He had urinary retention and his vesical urine volume was 1,450 ml. X-ray examination and ultrasound examination revealed a giant vesical diverticulum and moderate hypertrophy of the prostate. A vesical tumor was suspected. Cystometrogram revealed a flaccid pattern with vesical capacity over 900 ml. Diverticulectomy and resection for a vesical tumor were performed. A malignant neoplasm in the vesical diverticulum was found during the operation. Transurethral resection of the prostate was performed after two months. There has been no evidence of recurrence for 3 years postoperatively.
