HI, welcome to HCM
PSA is wihtin normal range so it os not a cancer , so dont worry about that.
Inhomogeneous echotexture, enlarged prostate
with pus cells and normal PSA points towards a infective pathology like abscess
formstion in prostate after UTI.
Your doctor is on right traclk and you also continue with antibiotics.
Dont worry and do repeat scan definately.
