CT scan
CT scan provides anatomic details and helps in distinguishing intrarenal and extrarenal pathologies.
It is difficult to distinguish hydronephrosis from pyonephrosis on a CT scan.
The indirect signs of pyonephrosis on CT scan include[1]:
Enlarged kidneys
Presence of an infected collecting system in the setting of hydronephrosis.
Perinephric fat stranding
Striated nephrogram[2]
Pelvic wall thickening
Fluid-fluid levels and gas within the collecting system can sometimes be seen
Other conditions like neoplasms
