title: [Malacoplakia in the ureter and bladder].
abstract: We report a case of malacoplakia in the ureter and bladder. A 78-year-old woman was admitted to our department for detailed examination of hydronephrosis. A small-fingertip-sized tumorous yellowish white lesion was detected by cytoscopy at a site that appeared to be the right side of the ureteral orifice. Transurethral resection was performed on the same site. Flat yellowish white protruding lesions were seen at two sites on the right ureter. Michaelis-Gutmann bodies were observed in biopsy specimens from both the bladder and ureter, and a diagnosis of malacoplakia was made. Ascorbic acid and bethanechol chloride were administered postoperatively. Endoscopy performed three months after the operation showed that the protruding lesions in the bladder and ureter had disappeared. Narrowing of the ureter or vesicoureteral reflux has not been seen to date.
