No Hydronephrosis noted

My husband and I were so happy to hear from my doctor that there was no hydronephrosis noted on our second baby's ultrasound. I had my ultrasound done last week and we are noe relieved after knowing the result. Our first son, Zachary, has a congenital hydronephrosis. So when the technician told me that we are having another boy again this time. My heart pump so fast because hydro is common to boys. It didn't bother me that our second baby is a boy again. What bothered me is the hydro. Thank You Lord for hearing our prayers.
