Ureteroarticular fistula after total hip replacement. A case report.

A fistula between the ureter and the acetabular space developed in a woman 69 years of age after revision surgery for a total hip arthroplasty. Symptoms were intermittent macrohematuria and swelling of the leg. The diagnosis was confirmed by arthrography and an elevated creatinine level in the aspirated fluid. After nephroureterectomy, symptoms disappeared. We conclude that the differential diagnosis of persisting unusual symptoms after total hip replacement has to include a fistula between the total hip prosthesis and urinary tract, even in the absence of open sinuses.
