title: [Grey-scale ultrasound in the diagnosis of cystic lesions of the kidney (comparison with excretory urography) (author's transl)].
abstract: In a total of 155 cystic renal lesions diagnozed by means of ultrasound the correct differentiation of cystic or solid consistency could be determined in 96.8% of cases. The sonographic result was inaccurate or false in only 2.6%. Sonography also determined the correct morphological and anatomical type of the liquid space-occupying formation in 89%. Pathological cavities of the renal pelvis as well as hydronephroses were the cause of incorrect diagnoses. 36.6% of solitary renal cysts revealed by ultrasound (average diameter of cyst: 3.9 cm), could not be detected by pyelography; radiology most frequently failed to determine cortical renal cysts. Sensitivity and specificity of nephrosonography for detection of cystic malformation of the kidney were distinctly better than pyelography. Out of a total of 34 patients with hereditary polycystic renal disease (HRPD) sonography diagnozed multiple cysts of the liver in 15 cases (44%). The use of ultrasound in examining relatives of patients with HPRD enables an earlier diagnosis of the chronic progressive disease.
