my dd has moderate hydronrphrosis, with dilated kidney but shes 4. it was only picked up this year after a scan, referred by gp after recurrent urine infections...
its thought she was born with a ureter narrowing that wasnt picked up, backlog of urine putting pressure on her kidney, and infections scarring the tube n making the blockage worse... its good that they picked this up early so it can be nipped in the bud.
at the moment, dd is under a urology specialist, on daily antibiotics to prevent more infections til its sorted. she had a renogram (scan with dye injected) to see kidney function and due for another scan soon... one kidney is draining about 2hours behind the other (which only takes a few minutes)...
as far as i know, treatment depends on the severity of the problem... with mild cases early on, theyll prob give low dose antibiotics to prevent infections and monitor it with scans... when they know the true nature of it or what issues its likely to cause, then they cn decide best kindof treatment...
theres a surgical procedure that can clear blockages, where i think they put in a stent or something to widen it, or to remove the blocked sectionof the tube... but i think they generally only use surgery if its necessary...
dd's consultant has been umming n ahhing about it for weeks, i wont find out the plans for another 2 months yet.
apparently its actually not uncommon to be born with a slight tube narrowing (so doc says) its about keeping an eye on it n seeing if the problem persists/develops... im sure bubba will be ok n well looked after
