title: [A case of ureteral and vesical malacoplakia].
abstract: A case of ureteral and vesical malacoplakia is reported. A 58-year-old woman was admitted for non-papillary sessile bladder tumor. Ultrasound examination revealed bilateral hydronephrosis and renal function was deteriorated. Escherichia coli and beta-streptococcus were isolated from her urine. Antegrade pyelography demonstrated obstruction of the bilateral ureters. Percutaneous pyeloscopy revealed a bean-sized yellow nodule at the upper portion of the right ureter. Pathohistological the lesions of aggregates of macrophage in which typical Michaelis-Gutmann bodies were found at the punch biopsies of both vesical and ureteral lesions. She was treated successfully with the administration of bethanechol chloride and antibiotics. This case seems to be the second report of ureteral malacoplakia in the Japanese literature.
