The Ultrasonic Study Of Renal Pelvic Liquid Diameter Of Fetuses

Objective: To investigate the normal value of the renal pelvic liquid diameter (RPLD) of fetuses in various gestational weeks and the diagnostic criteria of fetal hydronephrosis.Methods: The RPLD of 5988 kidneys in 3000 fetuses that were examined in January 2005 to January 2006 in our hospital was observed and registered with ultrasound. Statistical management constituted the normal value of the RPLD in various gestational weeks. The ultrasonic diagnostic criteria of fetal hydronephrosis were constituted by the RPLD, the pelvic dilatation, the renal size, the thickness of renal parenchyma and the relevant gestational weeks. The 78 kidneys that the RPLD was overstepped the normal value in the 50 choosed fetuses among them followed termly up and recorded the change and ending. The infants were followed still up and recorded the RPLD of them. The operational outcome was recorded if they were operated.Result: The RPLD of fetuses in various gestational weeks was...
