My baby girl is 10 month old before delivery in my last scan she was diagnosed with minimal splitting of pelvicayl system of 13mm left renal.after birth at regular intervals we did her scans now the measurement is 3mm.But the problem she still pees alot like every 20 mins she doesn't pee at one go.every time she pees is in big amount not less.and neither she cries while peeing.she does not have any kind of illness weight gain is also good everything is fine but then also I still worry of peeing.
