[Ureteral malacoplakia: a case report].

Malacoplakia is a condition which occurs most often in the urogenital system, but ureteral malacoplakia is rare. A case of ureteral malacoplakia is presented. The patients was a 54-year-old woman admitted to our hospital with high fever as the chief complaint. Laboratory data suggested urinary tract infection. Escherichia coli were isolated from the urine. Ultrasonography indicated left hydronephrosis and excretory urography showed reduced function of the left kidney. From retrograde pyelography, obstruction of the left distal ureter was indicated. A ureteral carcinoma was suspected and nephroureterectomy was thus carried out. The histopathological diagnosis was malacoplakia. The patient is in good health without any indication of the disease at 1 year 9 months following surgery.
