title: Renal trauma and hypertension.
abstract: A retrospective study (1972-1983) was made of 622 consecutive patients who suffered renal trauma, in order to assess the incidence and prevalence of post-traumatic renal hypertension. In 435 (76%) of the 569 survivors long-term followup data and blood pressure recordings were obtained, 13 months to 12 years after trauma (mean, 5.6 years). Renal trauma could not be linked to an increased incidence of hypertension: on first control, only 94 patients (21%) demonstrated a casual elevated blood pressure (greater than 140/90 mm Hg). The presence of a fixed hypertension was validated in only 14 patients. Twelve of them were extensively screened in the Department of Internal Medicine. In none of these patients could a definite relationship between hypertension and renal trauma be documented. Furthermore, an extensive review was done of 223 cases of post-traumatic renal hypertension reported in the literature from 1951 until 1984. Careful analysis of these previously described cases (71 publications) leads us to criticize the widespread accepted cause-effect condition with regard to post-traumatic renal hypertension. It is concluded that adequate management of renal injuries with early diagnosis and individualised surgical treatment can prevent this extremely rare complication.
