Successful surgical thrombectomy of renal allograft vein thrombosis in the early postoperative period.

We report the successful surgical treatment of two cases of renal vein thrombosis, each occurring early after kidney transplantation. Prompt intervention was a result of accurate diagnosis by color Doppler ultrasonography. Invasive radiological procedures were not useful.

[Which is the best performing imaging method for demonstrating residual renal calculi?].

Objectives: To compare the results of plain abdominal films, tomography, ultrasonography and spiral computed tomography in the detection of residual stone fragments after extracorporeal lithotripsy or percutaneous nephrolithotomy.

Material And Methods: Prospective study on 31 patients and 40 renal units comparing the results obtained by plain abdominal films, tomography, ultrasonography and spiral CT.

Results: This study demonstrates the superiority of spiral CT over the other examinations for detection of renal stones (sensitivity of 100% for spiral CT, 89.

[Evaluation of spiral computed tomography in the demonstration of kidney stones. Ex vivo study].

Objectives: The objective of this study was to determine, ex vivo, the limitations of spiral computed tomography (CT) in the detection of renal stones.

Material And Methods: Twelve fragments of calcium oxalate stones, 1 to 10 millimetres in diameter, were introduced into 3 porcine kidneys. Spiral CT was then performed on these kidneys.
