Does mild Kidney scarring cause pain

Ct/Kub/Contrast shows mild scarring on both kidneys. Could that be the cause of ongoing kidney pain after kidney stone blockage of the Urethra two years ago, that caused a blood infection. I presume this was the cause of a change in kidney function 67/33% Bloods/urine are ok. James

Can anyone advise on kidney scarring or where can I get info on the subject. Thanks James
