A case is reported of a disrupted femoral anastomosis and infected groin hematoma, which presented with massive hematuria and hydroureteronephro sis. This complication occurred nine months after aortofemoral bypass regraft ing, during which the ureter had been transected and repaired. The infected graft was removed, and the ureteric fistula closed spontaneously. The patient was fol lowed up for nine years until his demise from unrelated causes. The pathogenet ic mechanisms of these complications are discussed, and preventive measures are indicated.
