[A contribution to bladder amyloidosis].

It is reported on a localised primary amyolidosis of the urinary bladder with a progressing course. In contrast to the prevailing observations of other authors during two years an increasing bilateral urinary stasis developed so that finally after an at first unilateral nephrostomy due to an infected retention kidney the bilateral ureter-intestine-anastomosis became necessary. Apart from a short description of the amyloidosis from the general and especially urologi-al point of view it is particularly referred to diagnostic difficulties, since the various forms of amyloidosis have a different prognosis and demand a therapy.
