CT scan
CT scan provides anatomic details and helps in distinguishing intra-renal and extra renal pathologies.
It is difficult to distinguish hydronephrosis from pyonephrosis on CT scan.
The indirect signs of pyonephrosis on CT scan include:
Enlarged kidneys
Presence of an infected collecting system in the setting of hydronephrosis.
Perinephric fat stranding
Striated nephrogram
Pelvic wall thickening
Fluid-fluid levels and gas within the collecting system can sometimes be seen
Other conditions like neoplasms
