Mild renal pelvic dialation (both kidneys) has been identified for the first time at 27 weeks gestation on my baby boy, measurements range from 4 to 7 mm. I do however have an asymptomatic (not haemolytic and oxygen saturation normal) form of hereditary elliptocytosis, where 30-40% of red blood cells are elliptical. My research suggests that this is carried on the X chromosome and thus I may have passed the condition on to my son - my question is could this perhaps be the cause of this pelvic dilation?
I must appreciate your awareness about your Disease. I would like to re-assure you that one-sided pelvic dilatation during pregnancy is extremely common & less common is bilateral one.& is caused by pressure of pregnant Uterus over urinary bladder & disappears after delivery. Precaution to be taken to prevent UTI by maintaining adequate fluid intake, good hygiene, resting mostly on sides rather than on your back. Lastly, just to again assure you that Hereditary Elliptocytosis is certainly not the cause of Pelvic dilatation
