Hi, Thanks for writing in to us. The kidneys as mentioned above are normal in size. The renal pelvis is the area where the upper end of ureter, tube connecting kidney and urinary bladder starts. In the absence of stones or any infection of kidneys it is unlikely that the prominent renal pelvis is a matter of concern. It is mildly prominent and clearly mentioned no hyronephrosis. It is still possible that an infection can move from urinary bladder to kidneys and cause prominence of the kidney pelvis on both sides. This can be confirmed only if there is significant bacterial growth in your urine and if the bladder is also showing signs of infection and cystitis on ultrasound scan. The cysts are very small and will not cause any problems in your case.
