RENAL-VEIN THROMBOSIS - UNDER-DIAGNOSED COMPLICATION OF MULTIPLE RENAL ABNORMALITIES

In 31 cases of renal vein thrombosis (RVT) reviewed retrospectively for clinical, laboratory and radiographic findings, an underlying renal disorder was present in 28 cases and absent in 3. This supports other evidence that RVT is usually a complication of renal disease rather than a primary event and that nephrotic syndrome may be due to renal disease rather than RVT. The findings also confirmed the large spectrum of urographic appearances in RVT and were used as a basis for developing specific and liberal indications for renal venography.
