title: [Prevalence of arterial hypertension, proteinuria and hematuria in patients with simple renal cyst].
abstract: The simple renal cyst (SRC) is a common entity even though its actual incidence is difficult to determine given that it tends to manifest itself in an asymptomatic fashion. Occasionally, cases of SRC with clinical manifestations have been described in the literature, such as arterial hypertension (AHT) and biological alterations such as hematuria or proteinuria. The purpose of this article is to find the prevalence of AHT, proteinuria, and hematuria in patients with SRC detected via echography. 1,197 echographs that explored the renal area--a number equal to that of the number of patients--were reviewed. In 66% of the cases, the echographs were taken for some purpose unrelated to renal pathology. For those who presented SRC, blood pressure, proteinuria per 24 hours, and urine sediment were determined. SRC was detected in 93 patients (7.7%). The prevalence of AHT in patients with SRC was 31%, but 57% of those were older than 85 years. Two patients presented AHT and proteinuria; both fulfilled the criteria for nephrongiosclerosis. Two other patients presented hematuria and proteinuria; one was found to be afflicted with IgA nephropathy and the other with vesical carcinoma. A patient with hematuria was a carrier of renal lithiasis. We conclude that the prevalence of AHT in patients with SRC did not yield a significantly different result from that of the general population. In those patients who presented proteinuria and/or hematuria, one cause was found to be responsible; therefore, the presence of such alterations in patients with SRC should be considered coincidental.
