What symptom combination suggests renal vein thrombosis following renal transplant?

The combination of pain and swelling over the renal graft site is indicative of renal vein thrombosis after a renal transplant. This condition can occur when a clot forms in the renal vein, leading to impaired blood flow and resulting in localized symptoms at the site of the transplant.

Pain over the graft site may arise due to venous congestion or ischemia of the kidney, while swelling can result from increased capillary permeability and fluid retention associated with the compromised venous outflow. Recognizing these symptoms early is crucial for effective management, as renal vein thrombosis can lead to graft dysfunction if not addressed promptly.

The other combinations of symptoms do not specifically point towards renal vein thrombosis following a transplant. For example, increased urine output and normal creatinine levels could indicate adequate renal function rather than a complication like thrombosis. Severe abdominal pain with fever may suggest other conditions such as an infection or obstruction, and hypertension and edema might be more associated with fluid overload or other post-transplant complications, rather than directly signaling renal vein thrombosis.
