ULTRASOUND-EXPLORED ANATOMIC CHARACTERISTICS OF THE RENAL SINUS IN HEALTHY CHILDREN

In 195 with no manifest urinary tract disease, of the one to seven years of age,the ultrasound was used to determine the renal sinus dimensions (length and width),Their correlation with age and the kidnev dimensions was examined. The real-timemechanical sector scanner (ALOKA SSD 500) was used with convex probes of 3,5and 5 MHz in the supine position and in the counter-lateral body decubitus. The sinus dimensions kept on increasing continuously during the analysis period, mostintensely during the fifth year of age. The sinus enlargement was in a bettercorrelation with the kidney growth than with the childrens age. Still, there is anevident slight lagging behind in the sinus dimension growth comparing to the kidneydimension growth.
