Isolated fetal hydronephrosis: Beware the effect of bladder filling

The aim was to assess the role that fetal bladder size has in the determination of fetal hydronephrosis. Forty‐three fetuses were evaluated for fetal hydronephrosis in the second trimester of pregnancy. Anteroposterior measurements of the renal pelvis were obtained with a full bladder and again when...

description The aim was to assess the role that fetal bladder size has in the determination of fetal hydronephrosis. Forty‐three fetuses were evaluated for fetal hydronephrosis in the second trimester of pregnancy. Anteroposterior measurements of the renal pelvis were obtained with a full bladder and again when the bladder emptied in each fetus. Statistical analysis was performed using the Spearman rank order correlation coefficient to assess the relationship between bladder status and renal dilation. The anteroposterior size of the fetal renal pelvis diminished from 6.8 ± 1.8 mm on a full bladder scan to 4.5 ± 1.6 mm when the bladder was emptied (P
