[A case of leiomyoma of the urinary bladder in a woman with the chief complaint of total urinary retention].
Benign nonepithelial tumor of the urinary bladder is very rare. We experienced a case of a 33-year-old woman who complained of total urinary retention. Vaginal examination revealed a hen's egg sized retrovesical tumor. IVP revealed a filling defect on the cystogram. Cystoscopy revealed protrusion of left side of the bladder neck and intact mucosa. Transvaginal needle biopsy of the tumor was done, and pathohistological diagnosis of the tumor was done, and pathohistological diagnosis of the specimen was leiomyoma. The tumor was intramural type and was resected. It was 5.5 X 5 X 5 cm in size, weighed 80 g, and pathohistological diagnosis was leiomyoma of the urinary bladder. 57 cases of leiomyoma of the urinary bladder including this case have been reported in Japan. No special method of diagnosing leiomyoma of the urinary bladder exists, but in some cases, needle biopsy is very effective.
