[Treatment of post-reno-contusive arterial hypertension by upper polar nephrectomy. Results after 10 years].

The authors report the observation of arterial hypertension occurring six years after renal trauma, secondary to the upper polar infarction of the left kidney accompanied by a hypersecretion of bilateral renin and whose cure was obtained by partial nephrectomy. According to a literature review, it seems that post-reno-contusive arterial hypertension is not rare and can be due to various lesions whose common denominator is renal ischaemia. At present, no clinical or paraclinical element enables the prediction with certainty of the reversibility of the hypertension after the surgical intervention. However, the earlier the intervention, the better the chances of recovery, thus showing the importance of the systematic screening of renal lesions after lumbo-abdominal trauma.
