title: [Blood pressure observation during renal cyst decompression--case report on a benign solitary renal cyst as a cause of hypertension].
abstract: In patients with solitary renal cysts and only borderline hypertension for the exclusion of a connection a clarification by side-separated renin determination of the renal veins has been recommended (6). This investigation would finally clarify whether the affected kidney is responsible for the hypertension. However, this somewhat cumberous diagnostics is reserved for larger clinics. It is astonishing that in literature is scacely or not at all referred to the double diagnostic possibility of the puncture of the renal cyst: apart from the exclusion of malignity by cytologic investigation of the fluid and contrast representation of the cystic cavity a decrease of blood pressure after this relatively small intervention might refer to the necessity of further diagnostics. When at the same time a hypertension exists in punctures of the renal cysts one should therefore always use careful measurings of blood pressure before and after puncture, in order possibly to gain a valuable reference to a connection between the solitary renal cyst and the hypertension.
