[Total hematuria with normal intravenous urography. Apropos of 36 cases].

The authors present a critical study and retrospective of 36 cases of hematuria without urographic anomalies. Renal angiography was performed in 69% of the patients. 84% of these angiograms were negative. Only 2 identified the cause of the bleeding. 28% of the patients underwent disappointing surgery. In 40% of the cases the appearance of the kidney was normal. Only one of the 6 nephrectomies was justified. The authors recommend the use of modern and non invasive methods of investigation.
