Bladder tumor and foreign body after osteosynthesis of the femoral neck using screws and rods - a clinical case report

Femoral endoprosthesis surgery, sometimes referred to as hip replacement surgery, is a proven and effective method for treating a variety of hip joint problems. Despite being very uncommon, bladder issues after femoral endoprosthesis surgery might affect the patient's comfort and overall rehabilitation. Although Iatrogenic bladder injury in endoprothesis surgery is very rare, there are several cases described. Our report describes the case of a 65-year-old man who, due to long-term delay of removal of temporary femoral fixation devices, developed migration of the latter into the bladder cavity and rectal wall, with perforation of the bladder and the development of a malignant tumor of the bladder. The patient underwent resection of the left wall of the urinary bladder and evacuation of the fixation sticks from the side of the hip joint, as well as from the side of the pelvic cavity. All fixation devices were evacuated, resection of the left wall of the bladder without violating the integrity of the rectum. Additionally, excision of the iliac lymph nodes was conducted in one block. The postoperative period went without complications. According to control examinations, the general condition and act of urination were satisfactory. We believe that the case described above is interesting from both a theoretical and a practical point of view, as during an intervention such as femoral endoprosthesis, such iatrogenic complications as migration and perforation of a foreign body (in this case, operative material) in the surrounding anatomical structures are quite rare. It is important that, despite the pathology and the abundance of the latter's complications, the correct diagnosis and intervention took place, on the basis of which remission and complete elimination of complaints were achieved.
