Brief Answer:
There seems to be an obstruction which needs to be removed.

Detailed Answer:
Thanks for asking on HealthcareMagic.

I have gone carefully through the details provided. It seems that there is an obstruction somewhere in the renal tract. It so happens that if there is an obstruction, the urine gets retained and thus creating a backpressure. This pressure leads to the swelling of the ureters and the kidney canals, the conditions what we refer to as hydroureter and hydronephrosis. The kidney is trying to comepensate but the backpressure would cause damage to the kidney parenchyma or the functional area of the kidney, thus causing decrease in the parenchymal thickness. The condition is likely to worsen unless the cause of obstruction is removed. Posterior urethral valve (PUV) is the simplest form of obstruction but an assumption cannot be taken in this regard. I would suggest you to consult a pediatric nephrologist/urologist and discuss about undertaking a DMSA scan ( isotope scan ) for further evaluation of the same. Depending upon the findings, surgical intervention might be required.
