Ultrasound scan uses no radiation, good for screening for hydronephrosis, kidney cysts, tumors & stones. ...Read more
Recently found out that kidney enlarged due to hydronephrosis size of 18.8cm x 9.1cm x 10.4cm then renal scan no function is there a way to recover?
Hydronephrosis: A kidney that is completely obstructed may show porr to no function on renal scan. The kidney should be drained with a stent or nephrostomy tube and the renal scan repeated after 4 weeks with the drain in place. If there is still ni function, then removal may be indicated. Discuss this with your urologist as soon as possible. ...Read more
Having sharp pains under left rib, went for renal scan showed nothing but my CRP level is sitting at 43. Doctor doesn't know what it could be?
Need more info: This is not a site in which to attempt to establish a diagnosis, but would suggest that if you have had two abdominal surgeries in less than one year that your doctor should be looking assiduously for an intra-abdominal source of the pain, and a renal scan covers only the kidney. You might want to discuss this with them and if not satisfied consider getting a second opinion. Best wishes. ...Read more
I recently had a renal scan and after urinating an getting back on the table i couldn't see the left one only the right why? I have a stent already
Complicated Answer: Renal scans help determine blood flow, function and excretion from the kidneys. When there is not a kidney seen at the end of the study it could mean it was never seen(bad) or that it has completely emptied (good). With a stent i assume there was blockage. A renal scan is confusing to look at, since the left sided kidney is the left kidney. Your doctor will explain your findings in detail. ...Read more
