[Frequency and distribution of arterial hypertension in hydronephrosis kidneys].

By means of a retrospective study disease cases with urinary stasis in the kidney from 1978 to 1982 were investigated. 228 cases were evaluated. The different genesis was demonstrated, in which cases the ureterolith dominated as most frequent cause. 127 (55.7%) patients were hypertensives, whereas 101 (44.3%) had non-hypertensive blood pressure values. With regard to the duration and degree of the kidneys with urinary stasis there were no significant differences between hypertensives and non-hypertensives, though, the hypertensives showed a distinct (p less than 0.05) restriction of the renal function. The prevalence of hypertension of 55.7% in coincidence with urinary stasis in the kidney speaks for a certain causal connection between the two diseases. Investigations of the pressor and depressor systems might contribute to the further clarification.
