How long can it take to clear sludge from a kidney? My grandson is 8 and had surgery for a blocked ureter (it was a vein) twice. Now almost a year later he has similar pain. An ultrasound shows no frank hydro nephrosis. Surgeon suggested it is sludge. Can a CT scan show the presence of this?
Hello ya CT can show it but u don't need to go for CT unnecessarily for any so-called sludge.had the sludge been in any significant amount it would have appeared on ultrasound itself
