Acute renal vein thrombosis in adults

We had the chance to follow up 7 adult patients with acute R.V.T. for 3 years. Four patients had positive histories of either diagnosed or undiagnosed renal trouble. Dehydration was the most prominent predisposing factor seen in 3 cases of pilgrims due to low fluid intake and hard physical effort in severe hot weather (42-44 degrees C). Massive haematuria and severe lumbar pain were the most characteristic clinical symptoms. With the aid of ultrasonography, we were able to detect perirenal collections in 4 cases. Careful clinical examination, retrograde pyelography and ultrasound examination were found to be non-invasive diagnostic modalities.
