[Migration of cement into the bladder after total hip replacement (author's transl)].

The authors report a case of total hip replacement followed by early infection. The prosthesis was removed after several months but despite this a fistula persisted. Four years later, signs of bladder infection appeared. The patient was operated on and a piece of cement was found inside the bladder and removed. The relationship between the infection and the migration of cement into the bladder is discussed. It was recalled that nay intrapelvic protrusion of cement should be avoided in the course of a total hip replacement.
