It is not calculus or cancerous. Parenchymal calcification may be due to many causes like vascular etc. It is not a serious finding, and it is generally an age related finding. Main findings are thickened urinary bladder wall and significant post void residual urine. Thickened urinary bladder wall may be due to changes of cystitischronic infection in urinary bladder. As size of prostate is normal, significant post void residual urine may be related to neural component. Findings also suggest a small cyst in kidney, it is generally age related developmental finding. In short, findings doesnt indicate cancer or calculus. You need proper evaluation by a urologist.
