Dear friend, welcome to HCM.
USG size is little subjective too, and can vary to some extent on different ocassions.
one good thing is that the renal functyions are normal as per your info.
mobile stones can also cause obstruction, UTI, (infections ), fullness/ dilatation of calyceal system and slowly with repeated attacks , kidney
function may worsen.
so, keep close follow up, report any fever
, pain, bleeding per urinary tract
, pus in urine etc early.
do you still get pain, UTIs?
lab tests (creatinine
) get abnormal after >70% kidney function is lost !
what tests have you undergone?
pl. post them or ask your doc to rule out CKD
take care and keep me posted on your progress.
