[Diagnosis and surgical treatment of renovascular hypertension in patients with a single kidney]. / Diagnostik und chirurgische Behandlung der vasorenalen Hypertonie bei Patienten mit Einzelniere.

ABSTRACT

The study is based on an analysis of the results in operative treatment of 55 patients with vasorenal hypertension, when a functional single kidney is existing. The examinations showed that in the majority of patients function of the kidneys and renin activity in the peripheral blood were normal. The operation performed most frequently in this group of patients were the transaortal endarterectomy by means of the turning-up technique and the resection of the renal arteries with following reimplantation into the aorta or the end-to-end anastomosis. The analysis of the early and late results showed that the surgical intervention in patients with functional single kidney renders possible not only a normalisation or decrease of the arterial blood pressure but also significantly improves the renal function.
