Malakoplakia of the urinary tract.

five cases of malakoplakia of the urinary tract are described. It is much more common in middle-aged females (peak incidence in the fifth decade compared with the seventh decade for males) but remains an uncommon condition, although clinically there is a strong association with recurrent urinary tract infection. It causes obstructive stenotic lesions of the ureters or pelviureteric junction, which pose the serious threat. Many cases are associated with non-malakoplakic diseases of other systems which often determine the prognosis. The most commonly used method of treatment was long-term antibiotic therapy; this seemed effective, although controlled trials have not been performed.
