Echographic dynamic control of the urinary system and fetal development in pregnant women with acute pyelonephritis

: Ultrasonography in 52 pregnant women with acute pyelonephritis has been found to be a useful marker of efficacy of aggressive care. Reversal of inflammation in acute pyelonephritis without an associated disease reduced the kidney size and restored urine flow by the end of the 7-9th day of therapy. In pyelonephritis coexisting with nephrolithiasis, reversal of inflammation did not completely restore urine flow until a stone in the urinary tract was passed or surgically removed. The clinical patterns of pyelonephritis were elucidated in congenital renal malformations. The urine flow was completely restored and kidney sizes were maximally contracted postpartum. With an early therapy, the fetal development was appropriate for gestational age. Frequently relapsing pyelonephritis concomitant with toxemia or severe congenital renal disease led to intrauterine growth retardation.
