[Predictive diagnostic value of renal blood flow measurement in renovascular hypertension (author's transl)].
To improve diagnostic procedures and preoperative prognosis in hypertensive patients with angiographically proven renal artery stenosis pre- and postoperative studies of renal hemodynamics (133xenon washout technique) were carried out in patients with normalized, improved and unchanged hypertensive blood pressure values following renovascular surgery. The results demonstrate that renal blood flow in both the operated and non-stenosed kidneys has to be in a normal range expecting a normalization of blood pressure. The existence of a preoperative normal cortical flow rate in the stenosed kidney may be a hint to a normalization of hemodynamic of the involved kidney following reconstructive surgery.
