[Ultrasonic criteria of chronic pyelonephritis]
Abstract:
Ultrasonic investigation of the kidneys in B-regimen was made in 45 patients with chronic pyelonephritis and mild, moderate and severe arterial hypertension aged 40-60 years. Renal function was intact in all the patients. The results give evidence of a considerable informative value of ultrasonic scanning in diagnosis of chronic pyelonephritis and of moderate correlation between changes of echoparameters in patients with chronic pyelonephritis and severity of arterial hypertension. These relations are significantly reflected by such biometric renal indices as a relative volume of the renal sinus and renal parenchymal index.
