Hello and welcome to HCM.
As an
Urologist, i can fully understand your concern.
Many people are born with a single
kidney, which doesn't cause any health problems, if it's normally functioning. It's usually slightly larger in size,compared to a normal kidney.You should get examined by an Urologist,urgently, as you've symptoms of left
flank pain with chills,frequency, and have a family history of
Diabetes,and are hypertensive.As your scan shows mild pelviectasia, You should get certain tests done, like 1.Blood routine,2.urine culture,3.FBS and HbA1C,4.CT-IVP.
After showing the reports to Urologist,proper treatment will be started. Till reports come,you may start, Tablet
Ciprofloxacin, twice daily,with the Paracetamol650mg,twice daily and 10-12 glasses water daily.
You may send reports to me, as a direct question,for an expert opinion.
Dr.Matthew J. Mangat.
