Hello and welcome to HCM.
As an
Urologist, i understand your concern,with regard to stone treatment.
You should know a few fundamentals, of tests done so far.
1.The left ureteric stone on
ultrasound,has confirmed,cause of pain.
2.Plain X-ray KUB, is not an accurate test, hence stone not seen well.
3.NCCT/plain CT-KUB is advised,as it's more accurate than ultrasound.
4.A 7mm stone,may reduce in size,with medical treatment given so far, and even pass off spontaneously.
If 7mm stone still seen on plain
CT scan,clear it with
lithotripsy (URS).
5. Drink 12-15 glasses fluids daily,with potassium
magnesium citrate syrup, till stone is out,then minimum 12 glasses daily.
If you've any other doubts,send it to me as a direct question.
Dr.Matthew J. Mangat.
